     Field 
     The described embodiments relate to transportable datacenters. 
     Background 
     Many datacenter facilities have very high power requirements and can require substantial cooling to maintain computing equipment within its acceptable operating conditions. It can be advantageous to locate such datacenter facilities in geographical locations with relatively low-cost electrical power, cold ambient air temperatures, or a combination of both. In a datacenter, electrical power is used for two things: to power the many microprocessors within, and to drive cooling of the microprocessors to maintain a safe operating temperature. 
     Active cooling (i.e. using a chiller, condenser, pump, cooling towers, etc.) is one commonly used option for cooling the datacenter. This approach has drawbacks however, including high electrical power requirements, high equipment costs, and high maintenance costs. 
     The economics of data processing on a large scale often vary considerably based on the availability of low-cost power. Cold ambient air is desirable as an input to reduce electrical power consumption for cooling. The opportunity to exhaust heated air into the atmosphere is also desirable. 
     Conventional datacenter design has drawbacks that inhibit such designs from use in transportable datacenter facilities. For example, conventional datacenter design generally involves air intake from fans or an air conditioning unit via a raised floor having gratings generally in front of each rack in the cold air plenum, and air exhausted upwards and into a return air plenum in the ceiling. Such a design itself presents numerous challenges for use in transportable datacenter facilities. For example, access to the server racks in the datacenter requires operator access to the cold air plenum directly in front of the processors in the rack, and operator access to the hot air plenum directly behind the processors in the rack. The requirements for operator access in datacenters having a cold air plenum beneath the raised floor and the hot air plenum above the server racks mean that frequently the cold air plenum and the warm plenum do not have barriers defining the plenums as between different racks. It is desirable to provide a more practical design for cooling a transportable datacenter. 
     The location of low-cost power and cold ambient air is often distant from population centers and areas of industrial manufacturing, making the utilization of the low-cost power and cold ambient air difficult. It is desirable to provide transportable datacenter facilities that can be manufactured in convenient manufacturing facilities and then transported to appropriate locations where they can more efficiently be put into operation.

However, it will be understood by those of ordinary skill in the art that the embodiments described herein may be practiced without these specific details. In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the embodiments described herein. Furthermore, this description and the drawings are not to be considered as limiting the scope of the embodiments described herein in any way, but rather as merely describing the implementation of the various embodiments described herein. 
     It should be noted that terms of degree such as “substantially”, “about” and “approximately” when used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. These terms of degree should be construed as including a deviation of the modified term if this deviation would not negate the meaning of the term it modifies. 
     In addition, as used herein, the wording “and/or” is intended to represent an inclusive-or. That is, “X and/or Y” is intended to mean X or Y or both, for example. As a further example, “X, Y, and/or Z” is intended to mean X or Y or Z or any combination thereof. 
     Reference is first made to  FIGS.  1 - 3 A , which illustrate a transportable datacenter  100 . The transportable datacenter  100  has a housing  102  which, in this example, is a transportable shipping container having sidewalls  104  and  106 , end walls  108  and  110 , a floor  118  and a ceiling or roof  120 . The housing  102  may be a typical shipping container suitable for transport by truck, rail or boat. The housing  102  will typically be made of rigid, weather resistant material capable of withstanding an outdoor environment. The housing  102  of the transportable datacenter provides a generally weather resistant and enclosed volume in which other elements of the transportable datacenter are installed. In some embodiments, the housing may be freight container or a transportable intermodal container compliant with a corresponding standard such as ISO  668  or ISO  1496 . In some cases, multiple transportable datacenters may be stackable one atop another. 
     Transportable datacenter  100  has a ventilation system for cooling processors that may be installed in the transportable datacenter. The cooling system may also serve generally to provide ventilation through the transportable datacenter. Ventilation is provided through the transportable datacenter  100  by air flowing through datacenter from an air intake to an air exhaust, typically from one sidewall to the opposing sidewall. In transportable datacenter  100 , ventilation is provided from sidewall  104  to sidewall  106 . Sidewall  104  having the air intake may be referred to as the intake side. The sidewall  106  having the air exhaust may be referred to as the exhaust side. 
     Air intake sidewall  104  has one or more air intake openings  114  to allow intake of cool air from the environment. Each of the intake openings  114  will typically have a filter or other protective element installed in the intake opening to reduce the flow of dirt, dust and other particulate matter and contaminants into the transportable datacenter  100 . The air intake openings may have baffles or other physical protective elements to reduce the flow of rain and other materials into the transportable datacenter  100 . In some embodiments, some or all of the intake openings may have an air intake fan installed within them. 
     The intake openings may be sized identically or differently from one another, for example, as shown, intake opening  114   a  may be smaller than the intake openings  114   b ,  114   c , and  114   d.    
     The end wall  110  may have a door  124  that allows operator access into the transportable datacenter  100 , typically into a cold air plenum  154 . 
     Air exhaust sidewall  106  has air exhaust openings  116  to exhaust hot air from within transportable datacenter  100  to the environment. Each of the exhaust openings  116  will typically have an exhaust fan  128  installed within it. The exhaust openings may be sized identically or differently from one another. For example, as shown, exhaust opening  116   a  may be smaller than exhaust openings  116   b ,  116   c , and  116   d . As with the air intake openings, the air exhaust openings  116  may have a filters or baffles or both to protect the interior of the transportable datacenter from contamination. 
     A plurality of racks are installed in the interior of the transportable datacenter  100 . While seven racks are shown in this example, other numbers of racks may similarly be installed in the transportable datacenter. Each rack  134  has a plurality of shelves  136 , with each shelf  136  having a plurality of processor bays  138  having a front face  140  and a rear face  142 . In operation, a processor  500  ( FIG.  5   ) may be installed in each of the processor bays  138 . 
     Reference is next made to  FIG.  3 B , which shows a cutaway portion view of a transportable datacenter  100 . In one embodiment an external intake fan  180  is disposed outside of the transportable datacenter  100 . The external intake fan  180  may have baffles or other physical protective elements to reduce the flow of rain and other materials into the transportable datacenter  100 . In a similar fashion, the exhaust fans may be disposed outside of the transportable datacenter  100  as well. The external exhaust fans may have baffles or other physical protective elements to reduce the flow of rain and other materials into the transportable datacenter  100 . As shown in  FIG.  3 B , the external intake fan  180  may be larger than the intake opening  114 , which may allow for larger intake fans that intake a higher airflow rate, or a higher volume of air per minute than an intake fan disposed inside the intake opening  114 . An external intake fan  180  that is larger than intake opening  114  may allow for increased laminar flow into the transportable datacenter. The external intake fan  180  may extend and be generally sized to the height of the transportable container  100 . The external intake fan may extend beyond the perimeter of the transportable container  100  (not pictured in  FIG.  3 B ). 
     It is generally understood that the cross-section of the fan blade path in an intake fan is circular, and that the intake fan may further comprise a fan housing. The external positioning of the intake fan  180  may allow for the intake opening to be completely covered with the cross-section of the fan blade path of intake fan  180 , whereas an intake fan disposed within the intake opening  114  would include a housing partially obstructing the opening  114 . Further, the external intake fan  180  may provide a higher airflow rate by ensuring the intake opening is covered by an inner portion of the cross-sectional of the fan blade path, the inner portion having a higher airflow than an outer portion of the cross-section of the fan blade path. The increased airflow in the inner portion of the cross-section of the fan blade path as compared to the outer portion of the cross-section of the fan blade path may be due to potential edge effects of the fan blades. 
     The external intake fan  180  may be installed on the outside of the transportable datacenter  100  when it arrives at an operational site. The installation of the external intake fan  180  may be done using fasteners, straps, or any known method. The external intake fan  180  may be removably attached to the transportable datacenter. 
     Similar to the above description of external intake fan  180 , the exhaust fans may also be external to the transportable container and sized larger than the exhaust openings. 
     Reference is next made to  FIG.  4 A , which illustrates the intake side of a rack  134 . The rack  134  has a plurality of shelves  136 , each shelf  136  having a plurality of processor bays  138 . Each processor bay  138  can accommodate a processor  500 . 
     Each processor bay  138  may have a liner along the intake or exhaust side of the processor bay. The liner may be a thermally insulating foam liner, that provides thermal insulation between the hot plenum and the processor bay  138 . The liner may line the processor bays  138 , and optionally the plurality of shelves  136 . The liner may act as a gasket between the processor bay  138  and a processor  500  to provide an air seal around the intake edges of the processor  500 . The liner may have be made from a fire resistant material. The liner may provide a frictional attachment between the processor  500  and a processor bay  138 . 
     Referring to  FIG.  4 B , which illustrates the exhaust side of the rack  134  of  FIG.  4 A . The exhaust side panel  522  may have a thermally insulating foam liner similar to the foam liner of  FIG.  4 A . The exhaust side of rack  134  may have an exhaust flap  520  for a processor bay  138 . While only flaps  520  for a single row are shown, there may be one flap for each processor bay in the entire rack. The exhaust flap  520  may extend from either side of the processor bay  138 . The exhaust flap  520  may have a varying angle compared to other processor flaps relative to the rack. The angle of the flap  520  may be determined based on the airflow through the processor bay  138  and the proximity of the processor bay  138  to the exhaust opening of the hot air plenum. The exhaust flap is for channeling the air exhaust output into the hot air plenum. 
     Referring also to  FIG.  5   , typically, a processor  500  will be a self-contained or substantially self-contained computing unit. Some processors may have an external power supply  518  that is mounted to or sits adjacent to the processor  500 . Other processors may have an internal power supply or may not require a power supply. Each processor  500  is installed in the corresponding processor bay  138 . In transportable datacenter  100 , this is accomplished by placing in the processor (including, if present, its power supply or any other external components) in the processor bay  138 . In other embodiments, a processor  500  may be fixedly mounted in a processor bay  138  with one or more fasteners. Each processor has a maximum cross-section from its front  504  to its rear  506 . In some cases, the cross-sectional size of a processor may be generally consistent from front to rear, such as in the case of a processor that has a processor housing  508  that is generally shaped as a rectangular cuboid with three sets of opposing generally parallel faces. Each processor bay  138  is preferably shaped to conform to the cross sectional shape of the processor  500  that will be positioned in that processor bay  138 . In some cases, an optional processor bay trim may be used to reduce or eliminate gaps between the processor and the sides of the processor bay. In some embodiments, the processor bays may not be specifically shaped to conform to the cross-sections of processors. In some embodiments, the processor bays may be positioned sufficiently close to one another that the majority of air flows through the processors positioned in the processor bays, and relatively little air flows between the processors. In some embodiments, the processor housings may contribute to the cooling of some or all of the processors and the processor bays may be spaced to allow airflow between the processor housings to cool the processor housings. 
     In some cases, during the operation of transportable datacenter  100 , a processor bay  138  may not have a processor  500  installed in it. Such empty processor bays  138  may have a blanking panel  524  installed in them. The blanking panel  524  blocks all or most of the cross-section of the processor  138  to reduce or eliminate airflow through the empty processor bay  138  as is shown in relation to processor bay  138   e.    
     In operation, each processor  500  generates heat, as is typical with computing devices. A processor  500  may have an optional processor cooling fan  512  that draws cold air into the front of the processor. As air flows through a processor  500 , it absorbs heat generated by the processor and thereby cooling the processor. A processor may have a processor cooling fan that expels heated air from the rear of the processor  500 . Some processors may have both an intake cooling fan and an exhaust cooling fan while other processors may not have any such cooling or ventilation fans. 
     Transportable datacenter  100  includes a relatively large number of processor bays, allowing for many processors to be installed within it. Transportable datacenter may be particularly suitable for tasks that require substantial parallel processing by many processors, such as mining cryptocurrencies, identifying large prime numbers, operating blockchain based information systems and many other such tasks. 
     Reference is next made to  FIG.  6   , which illustrates air flows created by the ventilation system through transportable datacenter  100 . Each rack extends from a hot air plenum barrier  158  to the exhaust sidewall  106  of the housing  102 . The front face  140  of each processor bay  138  opens into a cold air plenum  154  (which may also be referred to as a cold air zone). The rear face  142  of each processor bay  138  opens into a hot air plenum  156  (which may also be referred to as a hot air zone). The airflows in transportable datacenter  100  include intake airflows  602  and exhaust airflows  604 . Intake airflows  602  extend from the intake air openings  114  on the intake side of housing  102  to the front of the processor bays  138  through the cold air plenum  154 . Cold intake air then flows through the processor bays  138 , where it cools processors  500  installed in the processor bays  138  and which warms the air. The warmed air exits from the rear of the processor bays  138  into the hot air plenum  156 . The warmed air is then exhausted through the exhaust side of the housing as shown by exhaust airflows  604 . 
     In transportable datacenter  100 , the hot air plenums  156  are substantially fluidically isolated from the cold air plenum  154  so that warmed air exiting the rear face  142  of the processor bays  138  does not substantially mix with cold air that has not yet reached the front face  140  of the processor bays  138  when the ventilation system is in operation. The ventilation system progressively draws air from the environment of the transportable datacenter  100 , through the air intake openings  114 , the cold air plenum  154 , the processor bays  138 , the hot air plenums  156  and then through the exhaust air openings  116  back to the environment of the transportable datacenter. 
     For example, hot air plenum  156   a  is enclosed or contained within a volume or space defined by hot air plenum barrier  158   a , end wall  110 , side wall  106  and the rear faces  142  of the processor bays  138  on a first rack  134   a . Rack  134   a  may extend from the floor  118  to the ceiling  120  of the housing, in which case, the floor and ceiling  120  also define the enclosed volume of hot air plenum  156   a.    
     Hot air plenum  156   b  is enclosed between the rear faces of racks  134   b  and  134   c , a hot air plenum barrier  158   b  and side wall  106 . Racks  134   b  and  134   c  may not extend to the ceiling  120  of the housing  102 . Instead a hot air plenum cover  160   b  (shown cut away in  FIG.  3 A ) is installed between the tops of racks  134   b  and  134   c . The hot air plenum cover  160   b  also defines the enclosed volume of hot air plenum  156   b . The hot air plenum may be enclosed in other manners, for example, if a rack does not extend to the ceiling  120 , a hot air plenum barrier may be installed from the top of the rack to the ceiling  120 . This may allow a hot zone with a larger volume, and possibly larger exhaust fans with greater air moving capacity to be used, provide greater air movement through the transportable datacenter and greater cooling for the processors  500 . 
     Similarly the other hot air plenums  156   c  and  156   d  are enclosed between respective racks  134 , a hot air plenum barrier  158  and sidewall  106 , as described above. 
     In transportable datacenter  100 , intake airflows  602  and exhaust airflows  604  are generated by exhaust fans  128 , which draw relatively cold air from the environment through the intake air openings  114 , along intake airflows  602 , through processor bays  138 , exhaust airflows  604  and out of the transportable datacenter  100  through exhaust air openings  116 . Some or all of the processors  500  installed in processor bays  138  may include processor intake fans  512  or processor exhaust fans  514  or both. Processor fans  512  and  514  move cold air from the cold air plenum  154  to the hot air plenum  156  through the corresponding processors  500 . When provided, the processor fans also contribute to generation of the intake airflows  602  and exhaust airflows  604 . As noted above, air intake fans may be installed in some or all of the air intake openings  114  to blow relatively cold air from the environment of transportable datacenter  100  into the cold air plenum  154 . In various embodiments, a transportable datacenter  100  may include any combination of cold air intake fans, processor fans on processors  500 , and hot air exhaust fans  128 . In any particular embodiment, at least one type of fan will be provided. 
     Referring to  FIG.  7 A , transportable datacenter  100  has an electric power terminal  714 , which may include a one or three phase interface for receiving an external power supply from an external power source. Power terminal  714  is coupled to a series of power supplies  716  mounted on the hot air plenum barriers  158  facing the cold air plenum  154 . From each power supply  716 , a cable assembly  718  provides a bay power signal to each processor bay  138  in the adjacent racks  134 . The cable assembly  718  may include power cables and power cable harnesses that connect the power supply to a power plug  720  positioned at each processor bay. The bay power signal provided at each processor bay has a voltage suitable for the processor to be installed at that bay, with sufficient power to provide the processor&#39;s power requirements. 
     In some embodiments, the power supply may simply couple the external power source to the power plug  720  positioned at each processor bay. For example, this may be done if the external power supply provides power at a voltage suitable for directly powering the processors. 
     In other embodiments, the power supply may include one or more transformers to transform the external power supply to bay power supplies having one or more voltages suitable to power the processors. The appropriate bay power signal for each processor bay is provided at each respective power plug  720  at each processor bay  138  through the cable assembly  718 . 
     In various embodiments, there may be any number of power supplies  716 . For example, some transportable datacenters may include a single power supply  716  that provides power to each processor bay, while others may include a plurality of power supplies located proximate different groups or racks of processor bays as shown in  FIG.  7 A . 
     In the present example embodiment, each power supply includes a power supply panel that includes switches to selectively enable and disable the bay power supply at each processor bay. Each switch may be part of a circuit breaker that can automatically disable a bay power supply if an over-current, over-temperature or other trigger condition occurs. In some embodiments, the power supply may consist of a cable assembly that couples the external power supply to a power plug at each processor bay without any intervening switches, transformers or other elements. 
     Electric power from the external power supply is also used to power any intake fans (if provided in any particular embodiment) and exhaust fans  128  (if provided in any particular embodiment) built into the transportable datacenter  100 . Each intake fan and exhaust fan will typically be powered from a fan power supply  722  that provides an appropriate power signal for each intake fan or exhaust fan. In some embodiments, the intake fans and exhaust fans may simply operate at full capacity when they are powered up. 
     In other embodiments, some or all of the intake fans or exhaust fans may include an onboard speed controller that adjusts the speed of the respective fan in response to one or more measured air temperatures. For example, each fan may include or be connected to temperature sensors that measure the air temperature in the environment of the transportable datacenter, in one or more areas of the cold air plenum, or within one or more areas of one or more of the hot air plenums, or a combination of those locations. The fan may adjust its speed in response to the measured temperatures. For example, an exhaust fan will typically operate at a higher speed in response to a higher air temperature in the corresponding hot air plenum. An intake fan may operate at a higher temperature in response to a higher air temperature in any of the environment of the transportable datacenter, the cold air plenum or a hot air plenum. In any particular embodiment, each fan may be configured to adjust its speed in response to various temperature conditions, or combinations of temperature conditions in order to maintain a desired temperature or temperature range within one or more areas of the transportable datacenter. 
     In some embodiments, some or all of the intake fans or exhaust fans may operate under the control of a central fan controller. The central fan controller may be coupled to temperature sensors that sense air temperatures in the environment of the transportable datacenter, in one or more areas of the cold air plenum, or in one or more areas of one or more of the hot air plenums, or in a combination of those locations. The fan controller may vary the speed of each intake fan or exhaust fan to maintain a desired temperature or range of temperatures within one or more areas of the transportable datacenter. 
     Controlling the speed of some or all of the intake fans or exhaust fans provided in any particular embodiment may reduce the power consumption of transportable datacenter. For example, when a transportable datacenter operates in a colder environment, less air flow may be required through the transportable datacenter to maintain desired temperatures. Other factors affecting the cooling requirements of a transportable datacenter may include the number of processors installed in the transportable datacenter, the layout of racks and processor bays, heat generated by the processors (which may vary from processor to processor, or from rack to rack, or both), or the rate of change of temperatures in the environment or interior of the transportable datacenter. 
     Reference is next made to  FIG.  7 B , where an alternate embodiment of an electric power system for transportable datacenter  100  is shown. The electric power terminal  754 , includes an interface for receiving an external power supply from an external power source. Power terminal  754  is coupled to each of the racks  134 . At each rack  134 , a bus bar  758  provides a bay power signal to each processor bay  138  in racks  134 . The bay power signal may be provided by a plug attached to the bus bar  758 , the plug connecting to a processor disposed in the processor bay  138 . The bus bars  758  may be integrated with the rack  134 , and may have an integrated bus connection that may couple with the bus bar  758  with the plug via a terminal, a clip, a crimping connection, or another electrical connector. The bay power signal provided at each processor bay has a voltage suitable for the processor to be installed at that bay, with sufficient power to provide the processor&#39;s power requirements. Optionally, there is a relay system (not shown) provided allowing a user to disable a rack, a shelf in a rack, or the transportable datacenter. The electric power system having bus bars  758  may enable easy processor installation. 
     Reference is next made to  FIG.  8   , which also illustrates transportable datacenter  100 . Transportable datacenter  100  includes an external communication network connection  802 . Typically, the external network connection  802  allows processors and other computing devices in transportable datacenter  100  to communicate with external computing devices using an external data communication network  806  such as the Internet or another communication network. 
     External network connection  802  is coupled to a data network  804  within transportable datacenter  100 . The data network  804  may include various network devices such as routers, switches and cables to provide network connectivity at some or all of the processor bays. The data network  804  may include wireless communication devices  808  that facilitate wireless communication between network devices and between processors and the data network. Any particular processor bay may be provided with either wired or wireless network connectivity or both, allowing a processor in the processor bay to communicate with other devices (including other processors) coupled to the data network  804 , and to communicate with external computing devices. 
     A transportable datacenter may be designed for transport in various ways. Transportable datacenter  100  has a housing  102  which is a transportable shipping container. The shipping container is adapted to be transported by truck, rail or ship from a location at which it is manufactured to a location at which the transportable datacenter will be put into operation. For example, the shipping container may include twistlocks  162  ( FIGS.  1 ,  2   ) or other appropriate mounts to allow the container to be mounted on a truck, trailer or rail car or other transport platform. In other embodiments, a transportable datacenter may be built on a frame or base that has or can be equipped with wheels for transportation. For example, a transportable datacenter may be built on a trailer that can be hitched to a truck for transport. In some embodiments, the mounts used to mount a transportable datacenter for transportation may also be used to stack multiple transportable datacenters. 
     Referring to  FIG.  9   , a transportable datacenter may be installed by method  900 :
         At  902 , manufacturing or assembling the transportable datacenter at an assembly facility manufacturing facility is shown. Manufacturing or assembling the transportable datacenter includes:
           Providing a housing having air intake openings and air exhaust openings.   Installing a plurality of racks in the transportable datacenter, with each rack including a plurality of processor bays.   Substantially fluidically isolating the cold air plenum at the front face of the processor bays from the hot air plenum at the rear face of the processor bays.   Installing a cooling system for progressively drawing air from an environment of the transportable datacenter through the air intake openings, the cold air plenum, the processor bays, the hot air plenums and through the air exhaust openings back to the environment.   
           At  904 , the assembled transportable container is transported to an operating location.   At  906 , the transportable datacenter&#39;s external power supply is connected to an external power source.   At  908 , the transportable datacenter&#39;s external communication network is connected to an external data communication network.   At  910 , installing processors in the processor bays of the transportable datacenter, by positioning each processor in a processor bay, and connecting each processor to a respective power plug and connecting the processor to the transportable datacenter&#39;s data network.       

     Once the transportable datacenter has been installed, the transportable datacenter may be initiated in operation by activating the intake fans (if provided), exhaust fans (if provided), and the processors. When the processors are activated, any processor intake cooling fans and processor exhaust cooling fans will be activated under the control of a fan controller built into the respective processor. 
     In some situations, the transportable datacenter may be substantially assembled prior to transport to an operating location, where assembly of the transportable datacenter may be completed. For example, the transportable datacenter may be shipped with protective covers over the intake openings  114  and the exhaust openings  116 . Intake filters and exhaust fans  128  may be installed at the operating location. Similarly, the transportable datacenter may be shipped without other elements installed in their final position, and those elements may be installed prior to putting the transportable datacenter into operation. 
     Reference is next made to  FIG.  10   , which illustrates a rack  1134 . Elements of rack  1134  that correspond to rack  134  are identified by corresponding reference numerals. In rack  134 , the processor bays are arranged generally at a right angle to the long direction of the rack. In rack  1034 , the processor bays  1138  are arranged at an oblique angle to provide a straighter path for air flow between the intake airflows  1602  and the exhaust air flows  1604 , potentially reducing turbulence in the air flow in the transportable datacenter, and potentially increasing the cooling effect of the air flows. Rack  1034  may be used for some or all of the racks in a transportable datacenter. 
     Reference is next made to  FIG.  11   , which illustrates another transportable datacenter  2100 . Elements of transportable datacenter  2100  that correspond to transportable datacenter  100  are identified by corresponding reference numerals. In transportable datacenter  2100 , the racks  2134  extend from hot air plenum barrier  2158  towards exhaust sidewall  2106 , but are spaced apart from the exhaust sidewall  2106 . This provides a hot air plenum  2156  that extends along the length of exhaust sidewall  2106  and allows additional exhaust fans to be installed along a greater portion of the length of sidewall  2106 , potentially providing greater airflow and cooling through the transportable datacenter. 
     Reference is next made to  FIG.  12   , which illustrates another transportable datacenter  3100 . Elements of transportable datacenter  3100  that correspond to transportable datacenters  100  and  2100  are identified by corresponding reference numerals. In transportable datacenter  3100 , the ventilation system includes a plurality of hot air mixing fans  3170  that are operable, under the control of a central fan controller, to draw air from one or more hot air plenums  3156  into to the cold air plenum  3154  through ducting  3172 . The central fan controller may activate and control the speed of the hot air mixing fans  3170  in response to temperature measurements in the environment, in the cold air plenum  3154 , or at one or more processors, or a combination of these and other locations. In some environments, cold air drawn from the environment of a transportable datacenter into the cold air plenum  3154  may be sufficiently cold to negatively impact the operation of the processors or other elements of the transportable datacenter. In those situations, it may be desirable to heat the air in the cold air plenum  3154  by mixing hot air from one or more hot air plenums  3156  into the cold air plenum. In this example, hot air from two hot air plenums  3156   b  and  3156   d  is mixed with cold air in the cold air plenum  3154 . In other embodiments, a greater or smaller number of hot air mixing fans  3170  may be provided to mix hot air from any number of hot air plenums into the cold air plenum  3154 . 
     Reference is next made to  FIGS.  13 A and  13 B  which illustrate another embodiment of a transportable datacenter  3200 . The transportable datacenter  3200  has intake ports  3206  on the roof of the transportable datacenter for providing ventilation of cool air from the environment into the cold plenum. Each of the intake openings  3206  will typically have a filter or other protective element installed in the intake opening to reduce the flow of dirt, dust and other particulate matter and contaminants into the transportable datacenter  3200 . The air intake openings may have baffles or other physical protective elements to reduce the flow of rain and other materials into the transportable datacenter  3200 . In some embodiments, some or all of the intake openings may have an air intake fan installed within them. The intake openings  3206  may be sized identically or differently from one another. The air openings provide intake air flows  3208  from the intake opening  3206  to the plurality of processor bays on the rack  134 .

In rack  134 , the processor bays are arranged generally at a right angle to the long direction of the rack. In rack  3314 , the processor bays  3318  are staggered in order to provide a straighter path for air flow between the intake airflows and the exhaust air flows, potentially reducing turbulence in the air flow in the transportable datacenter, and potentially increasing the cooling effect of the air flows. The two racks  3314  in a pair of racks may form a “v-shaped” configuration with an end of each rack in the pair forming an angle as shown. Rack  3314  may be used for some or all of the racks in a transportable datacenter. Intake openings  3306  are provided to allow for the intake of cooler air from the environment.

The recirculation of hot air may be controlled by an independent control mechanism. The ducting may be internal or external to datacenter  3350 . In this embodiment, air intake occurs through the intake openings  3306  on roof  3374 , but air may optionally intake through the intake openings  3306  on roof  3374  and intake openings on side wall  3372  (see  FIG.  2    at  116 ).

This independent control mechanism may be an air flow switch or a flue. The air flow switch may switch between recirculating hot air flow from the exhaust opening to the intake opening, and exhausting the hot air flow into the environment. The recirculation may be performed to increase the intake air temperature if the ambient air temperature in the environment is below an operating threshold for the processors disposed in processor bays  3368 .

The processor circuits  3714  may be wires, a bus bar, or another electrical power transmission device that interconnect the processor circuit breaker  3706  to the plurality of processor bays. 
     Referring next to  FIG.  17 B , there is shown a cross section view  3750  along the line  3710 - 3710  in  FIG.  17 A  showing a plurality of processor circuits.

The plurality of processor circuits  3708  distribute power from the integrated power system  3720  to the processor bays. 
     Referring next to  FIG.  18 A , there is shown a cutaway portion view  3600  of another transportable datacenter having an evaporative cooling system. The transportable datacenter shown in the cutaway portion view  3600  has two or more racks  3614  inside the transportable datacenter. Intake sidewall  3607  has intake openings  3606 , and exhaust sidewall  3608  has exhaust openings  3608 . A cold plenum  3602  is generally defined by the end walls (not shown), the intake side of the plurality of processors disposed on racks  3614 , and the intake sidewall. Intake fans may be positioned inside the intake openings  3606 . 
     Air from the ambient environment is drawn into the cold plenum using intake fans in the intake openings, and provides cooling as it passes through the plurality of processors in racks  3614 , and then the hot exhaust air exhausts the hot plenum  3604  via the exhaust openings  3608  in exhaust sidewall  3610 . 
     The transportable datacenter in  FIG.  18 A  further comprises an evaporative cooling system, having a pump  3617  in fluid communication with a fluid source, a intermediate pipe  3615  in fluid communication with the pump, and one or more output pipes  3612  in fluid communication with the intermediate pipe  3615 . The pump  3617  includes a motor, such as an electric motor, an internal combustion engine, or another motor means. The pump  3617  draws fluid from a fluid source, and has an output providing the fluid to the intermediate pipe  3615  at an increased pressure. The one or more output pipes  3612  extend from the intake sidewall  3607 . In one embodiment the output pipes  3612  extend generally in front of the intake openings  3606 . There may be an output pipe  3612  in front of each intake opening  3606 . The distal end of each of the output pipes  3612  has a nozzle (not shown) for providing a mist, or an aerosol  3616 , of the liquid pumped through the evaporative cooling system. 
     In one embodiment, the fluid used in the evaporative cooling system is water. In another embodiment, other fluids having higher values of enthalpy of vaporization may also be used, such as methanol or ethanol 
     In one embodiment, an optional collection pan  3632  may be provided to recover liquid from the one or more output pipes  3612 . 
     The nozzle of the output pipe  3612  receives pressurized cooling liquid through the output pipe  3612  and the intermediate pipe  3615  from the pump  3617 . The received liquid produces a mist  3616  as is exits through the nozzle of the output pipe  3612  into the ambient environment proximate to the intake sidewall  3607 . The mist  3616  exits as liquid droplets and evaporates to generate liquid vapor. The evaporation is done using heat from the air in the ambient environment, thus cooling the air proximate to the intake openings  3606  of intake sidewall  3607 . 
     Optionally, a collection pan  3632  may be positioned underneath each of the one or more output pipes  3612  to collect water from the mist  3616  that does not evaporate. The collection pan  3632  may return the water to a reservoir to be reused. 
     The evaporative cooling system of  FIG.  18 A  may further be used in conjunction with the embodiments of the transportable datacenter shown in  FIGS.  1 ,  2 ,  3 A,  3 B,  6 ,  7 A,  10 ,  11 ,  12 ,  13 B,  14 ,  15 B,  15 D,  16 A, and  16 B . 
     Referring next to  FIG.  18 B  there is shown a side view  3630  of the transportable datacenter of  FIG.  18 A . The transportable container has end wall  110  having access door  124 . Extending from the intake sidewall of the transportable container, the one or more output pipes  3612  are shown extending generally parallel to the supporting surface below the transportable container. The output pipes  3612  each have a nozzle at the distal end, and generate a mist  3616  from liquid pressurized through the transmission pipe to the one or more output pipes  3612 . 
     In one embodiment, a collection pan  3632  is positioned below the output pipe  3612  to collect cooling liquid that does not evaporate. 
     Referring next to  FIG.  18 C , there is shown a system view  3660  of the evaporative cooling system of  FIG.  18 A . The evaporative cooling system has a pump  3617 , intermediate pipe  3615 , output pipe valves  3618 , processor  3634 , sensor  3636 , one or more output pipes  3612 . 
     The pump  3617  is a liquid pump such as a positive displacement pump, and includes a motor means such as an electric motor or internal combustion engine to drive it. The pump operates to draw liquid from a reservoir or liquid source into an input, and urge the liquid under pressure into the intermediate pipe  3615 . The pump may be in communication with the processor  3634 , for example, through the use of a relay, in order to enable the processor to programmatically control the operation of the pump. The control of the pump may be simply on/off, or may be a variable speed control. 
     The intermediate pipe  3615  carries pressurized cooling liquid from the pump  3617  to the one or more output pipes  3612 . The intermediate pipe  3615  may be a pipe or hose as is known, including for example polyvinyl chloride (PVC) piping. 
     Each of the one or more output pipes  3612  carry pressurized cooling liquid from the intermediate pipe  3615  to the distal end of the one or more output pipes  3612 . The distal end of the one or more output pipes  3612  includes a nozzle to produce a mist or aerosol  3616  of the cooling liquid in the ambient atmosphere proximate to the intake side of the transportable datacenter. 
     Each of the one or more output pipes  3612  may have an output pipe valve  3618 . The output pipe valve  3618  may have an actuator for operation of the valve to open, close, partially open, or partially close the valve. The closure of the valve may stop the flow of cooling liquid through the output pipe. The actuator for the output pipe valve  3618  may be in communication with the processor  3634 . The connection of the processor  3634  with the actuators of the output pipe valves may be done using a solenoid, or similar means, and may allow for the programmatic control of the fluid flow through the output pipes  3612 . The output pipe valves  3618  may be independently controlled by the processor  3634 , or may be operated together. 
     Each of the one or more output pipes  3612  may be generally aligned with an intake opening  3606  of the intake sidewall  3607  of the transportable datacenter. The operation of the evaporative cooling system generates a mist or aerosol  3616  of cooling liquid  3616  that evaporates in the ambient atmosphere to cool the ambient air prior to intake into intake openings  3606  of the intake sidewall  3607  of the transportable datacenter. 
     The sensor  3636  may be a temperature sensor, a light sensor, a humidity sensor, an optical sensor, or a combination of a light sensor, a humidity sensor, and an optical sensor. The sensor  3636  is in communication with the processor  3634  for providing sensor data on the ambient atmosphere. 
     The processor  3634  may be any computer having one or more processors that can provide processing power for controlling the evaporative cooling system and a memory for storing program instructions. Processor  3634  may be a desktop processor, for example, an Intel® Xeon®, or AMD° Opteron™. In another embodiment, the processor may be an embedded computer system such as an Arduino® or a Raspberry Pi®. In another embodiment, the processor may be a Field-Programmable Gate Array (FPGA), or a purpose built controller. In one embodiment, the processor is a proportional-integral-derivative controller (PID controller) that operates a control loop for the evaporative cooling system. 
     The processor  3634  receives sensor data from the sensor  3636 , and controls the actuators of the valves  3618  of the one or more output pipes  3612  and the pump  3617 . The processor control  3634  of the evaporative cooling system may begin cooling as the ambient temperature of the air entering the intake openings exceeds a threshold. Similarly, the processor control  3634  may reduce or disable the evaporative cooling system if the humidity at the intake openings exceeds a threshold. 
     The processor  3634  may further comprise a network controller. The network controller is any interface that enables the processor  3634  to communicate with other devices and systems. In some embodiments, the network controller can include a serial port, a parallel port, and/or a Universal Serial Bus (USB) port. The network controller  156  may also include at least one of an Internet, Local Area Network (LAN), Ethernet, Firewire, modem, or digital subscriber line connection. Various combinations of these elements may be incorporated within the network controller. 
     The processor  3634  may be in communication with the one or more intake fans (not shown) and the one or more exhaust fans (not shown) in conjunction with the pump  3617 , and the actuator of the output pipe valves  3618 . The processor  3634  may function to control the fan speed of the intake fans, and the exhaust fans based on the operation of the output pipe actuators. 
     Referring next to  FIG.  18 D , there is shown a system diagram  3680  of the evaporative cooling system. The processor  3634  may be available for connection for remote administration via network  3682 . A user at user device  3684  may connect to the processor remotely and administer the evaporative cooling system. 
     The network  3682  may be the Internet, Ethernet, a point to point connection, plain old telephone service (POTS) line, public switch telephone network (PSTN), integrated services digital network (ISDN), digital subscriber line (DSL), coaxial cable, fiber optics, satellite, mobile, wireless (e.g. Wi-Fi, WiMAX), SS7 signaling network, fixed line, local area network, wide area network, and others, including any combination of these, capable of interfacing with, and enabling communication between the processor  3634  and the user device  3684 . 
     The user device  3684  may be a personal computer, a smartphone, an electronic tablet device, a laptop, a workstation, server, portable computer, mobile device, personal digital assistant, Wireless Application Protocol (WAP) phone, an interactive television, video display terminals, gaming consoles, and portable electronic devices. The client system may operate to access the processor using a web browser, or using a client-server application, in order to administer the evaporative cooling system.
