Description:
BACKGROUND OF THE INVENTION AND THE PRIOR ART  
         [0001]    California recently has had rolling blackouts and power outages with disastrous consequences for health, convenience, and earnings, due to ill-considered legislation, attitudes, and practices. California has required power companies to supply power at a fixed price while preventing the same companies from contracting to buy power for a fixed price. Such laws, attitudes and practices have led to deterioration of electrical infrastructure in all of fuel supply, hydroelectric reserves, power-generation, and power-transmission lines. Other related facts of business in California include strict requirements on construction and complex, time-consuming and burdensome restraints and permitting associated therewith. Recent events may lead to improvements, but improvements will take a long time, and in the mean time there is a need for emergency power and for avoidance of the delays associated with construction of infrastructure.  
           [0002]    Some people and companies have recently obtained their own emergency power plants, all the way from little Honda package generators for keeping the food cold in the refrigerator to full-blown power plants on a building site, just as many hospitals, office buildings and industrial plants have always done, but the delays, the first investment, the devotion of building resources and site space, of construction of such plants all are burdensome. Having bought and installed a power plant, little of its value will be recoverable after the need has gone away.  
           [0003]    Portable generators are ubiquitous, all the way from the little motor-generators in the back of a pickup truck for use of job-site carpentry saws up to enormous multi-megawatt barge-mounted power plants, at least one of which was made in Japan and floated across the Pacific to serve as the power plant for a city and associated agricultural complex in Brazil. Jackup barges used for oil exploration and production offshore comprise large power plants, as do ships. However, all of these require infrastructure construction for safe service to land facilities.  
           [0004]    A particular type of portable motor-generator is the hybrid automobile, truck, and diesel-electric railway locomotive. Such cars are now offered by Honda and Toyota, such a truck is being developed by Lockheed-Martin and the U.S. Army National Automotive center, and the locomotive is ubiquitous. The power generated is for motivation of the vehicle, although it serves other ancillary purposes of the vehicle, such as headlights, horns, and large and small accessories, and the vehicles are not seen as being motor-generators in the usual sense.  
           [0005]    Packaged power plants such as are used by hospitals and stores to continue essential services during outages are well-known, but emergency provision of such a plant power plant for use by a food-processing or manufacturing plant involve all of the difficulties of new construction including especially delay and the taking up of space. Commonly the service entrance would be obstructed by such things as fireplugs and ancillary structures, so often even the placement of a portable plant in the yard would involve new construction, or exposure to the hazard of a jury rig.  
         BRIEF SUMMARY OF THE INVENTION  
         [0006]    The invention comprises a hybrid vehicle, i.e. a vehicle having a heat engine driving an electrical generator which produces motive power for the vehicle, said vehicle being converted to a site-stationary emergency power plant by incorporation of power conversion apparatus including switch gear and a transformer or an inverter, and inclusion of self-erecting transmission-line means and protective switch-gear for introducing the emergency power to the site. Also included for some embodiments are walking foundation means such as walking jacks or caterpillar tracks. A notable feature of the invention is the pre-engineering and pre-qualification of major parts under various codes so as to enable immediate temporary emergency stationary establishment without the expense and delay of site construction and permits except for the uncontroversial electrical service entry and switch.  
         THE OBJECT OF THE INVENTION  
         [0007]    The main object of the invention is to protect and improve the health, comfort, habitat, safety, and livelihood of people living where electric power is in short supply and in a time of troubles, largely by utilization of existing motor-generator capacity found in existing hybrid vehicles, thereby saving the people and the institutions of an area the burden of large and unrecoverable fixed investment made to get through a time of troubles which will end and, ending, thereupon obviate the continuation of need for the said investment. In particular, there are diesel-electric locomotives all across the country which can be mobilized very quickly and at low cost to meet these purposes as taught herein, since the ancillary power adaptation and transmission means of the invention cost only a fraction of what the standby diesel-electric skid-mounted motor-generators and accessories of installed systems costs, and since, even if the ancillary means were discarded they would cost about the same in money as and much less in time than their fixed-system counterparts of the prior art, but they would not be discarded, because they would be much more salvageable or re-usable elsewhere than fixed-installation such means, partly because they are on wheels. Another object of the invention is to save time and money in installation of auxiliary power supply by saving the time and troble associated with fixed construction an of removal of fixed construction, both of which require permits. Another object is to provide a new source of income to railroads having idle engines and utilities having idle pole trucks, and a related object is to provide relief from railway labor contract requirements of crew-member rank and crew size for stationary locomotive engines by removing the engines from the railway. Another object of the invention is to provide political subdivisions bargaining power and negotiating slack that they might not otherwise have by increasing alternatives. Another object is to provide a market for coal with attendant conservation of natural gas and other fluid fuels. Another object is to give military hybrid trucks the means to give AC power to facilities damaged in war. Another object is to provide rapid transmission-line installation and removal for emergencies.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0018]    [0018]FIG. 1 shows diesel-electric locomotive  1  having removable tap means  2  connecting and tapping into the 480 v. 3-phase AC generator within locomotive  1 , which said  1  is of the type wherein the diesel engine drives an AC generator, which in turn gives motivation to the locomotive wheels. Means  2  feeds the 480 v. AC to transformer-and-switch-gear hookup means  3  which is adapted to transform the power carried by means  2  selectively to conform to the demand at the emergency site to be served. Car  4  carries spool means  5  and knuckle-boom crane  6 . Attached to and behind car  4  is car  7 , car  7  being a diesel-fuel-carrying tank car carrying hose and pumping means  8 , which was installed previously partly by use of crane  6  before leaving the rail yard from which the whole came, before which car  7  was simply an ordinary tank car . Means  8  is for refuelling tractor means  1  during operation of said tractor  1  at a site of emergency power service, if and as needed. Means  8  can be handled from car  7  onto a newly-arrived replacement for car  7  by jackup legs  8   a  on means  8  and other self-mobilizing power and control means thereon not shown.  
         [0019]    [0019]FIG. 2 shows car  4  in end view and parked on track  9  at the site of emergency need, in deployment for emergency electrical service to building  10 . It happens that building  10  and other buildings not shown commonly receive 240 v. 3-phase service through weatherheads  11  (called  11   a  in case of building  10 , otherwise not shown) through pre-existing utility service transformer  12  on pre-existing pole  13 . Since transformer  12  is a stepdown transformer receiving 480 v. and delivering 240 v., transformer means  3  is set as if at 1:1, i.e. putting out the same as it receives, although it is adapted to other ratios and connectedness for other emergency sites as needed. In this view, means  5  seen before, but not shown in this Fig. feeds cable  14  through emergency switch gear  15 , set by the utility company on transformer  12  for this emergency, into the 480 v. primary side of transformer  12 . Gear  15  of the invention can be set to receive power from the preexisting line or from cable means  14  as desired, but not from both at the same time, thereby enabling the safety, economy, and convenience of isolation of the regular and emergency power supplies from each other and rapid conversion from one the one source to the other. The means  5  feeds line to crane  6  which then carries said  14  on insulators  6   a  of crane  6  to safe connection to switch  15 , and during power transmission by line  14 , means  5  interlocks with the motive means of crane  6  so as to prevent dangerous motions thereof. Track  9  is too far from building  10  for for the crane  6  to suffice to carry the line  14  all of the way, so truck  16  having knuckle-boom crane serves to support line  14  over a part of the distance, using insulator arm  17   a  of crane  17  for the purpose. Outrigger footings  17   b  are down to stabilize truck  16 , and portable concrete highway median casting  17   c  has been placed over footings  17   b  to further stabilize the whole.  
         [0020]    [0020]FIG. 3 shows truck  16  just seen, which happens to be a hybrid diesel-electric truck, and which has crane  17  on the back for usual knuckle-boom uses, as well as the use shown in FIG. 2, where crane  17  of said truck  16  had been modified to adapt it to emergency-pole use of the invention by addition of insulators  17   a . and by addition of ballast  17   c  to the usual outrigger footings  17   b . Truck  16  is a hybrid vehicle whose generator produces DC, not AC like tractor  1 ; such DC powers not only the wheels, but may power various tools and implements as desired. In this case, as in FIG. 2, this DC powers the compact knuckle-boom crane  18 . However, FIG. 3 shows inverter means  18  which was not present on truck  16  in FIG. 2. Inverter  18  has been added to convert truck  16  into an analogue of tractor  1  No detail is shown, since  16 ,  17  and  18  are analagous to 1, 6, and 3 of FIGS. 1 and 2, except that the whole runs on rubber and the power out of truck  16  is DC, so the conversion  17  is by inverter rather than transformer; so by reference to the foregoing FIGS. 1 and 2, and FIGS. 4 and 5 following, the whole emergency power plant of FIG. 3 may be easily be implemented by those skilled in the art. This shows the practice of an important benefit of the invention, that the elements of the invention are available for a variety of uses, and can be modified and remodified to reduce the first-cost penalty of the emergency power plants prior art.  
         [0021]    [0021]FIG. 4 shows yet another hybrid vehicle, this time an automobile  19  having a gasoline engine driving a DC generator charging a bank of batteries, but having the added feature of inverter and connection apparatus  20  in the trunk. Car  19  is shown parked in the garage of house  21  with hatch  22  open and apparatus  20  connected to pre-existing electric breaker box  23  with service conduit  24  of house  21  by cables  25  and  26  respectively, and by means to appear in FIG. 5 FIG. 5 shows details of parts of FIG. 4. Means  20  carries outlet box means  27  having circuit breaker  27   b  and selector switch  27   a  and having three outlet receptacles similar to those found in most houses in America, i.e. two 120 v. receptacles  28  and one 240 v. 1-phase receptacle  29 , the latter being shown occupied and plugged into by cable  25  leading to socket  38  to mate with shrouded connector means  39  on breaker body  30  at the other end. Box  27  also carries ground jumper cable  26  with clamp  31  for clamping onto ground means such as conduit  24  of FIG. 4, where cable  26  is shown to be so clamped. Means  30  is a 240 v. 1-phase circuit-breaker sufficiently resembling the circuit-breaker usually housed in breaker box  23  that means  30  can replace the said usual breaker, to provide the benefits of the invention to the owner of car  20  and of house  21 , including quick installation and switching between utility-company service and emergency service. Breaker  30  also has switch handle  32  and screw contact means  33  below which receive the usual to-be-hot wires of the house wiring circuits in the usual way when the said substitution is made. Breaker  30  has bus prong sets  34  and  35  resembling those of the pre-existing breaker, except in respects to be explained. In addition to the apparently usual features switch  32 , screw  33 , and prong sets  34  and  35 , body  30  also has prongs  36  and  37  in some correspondence to and alternative to prongs  34  and  35  respectively, i.e. they receive power from inverter means  20  when prong sets  34  and  35  do not serve to receive power. The prongs  36  and  37  receive it through cable  25  end socket  38  which goes into shroud  39  and around prong sets  36  and  37 ; shroud  39  is shown cut away in the FIG. 5. The body  30  contains sensors sensing not only electrical stress, but also mechanical stress in prongs  34 ,  35 ,  36 , and  37 , and contains logic and control means so that certain conditions are required to be met before certain actions can occur, to provide safety of operation. In particular,  
         [0022]    no electrical transmission can occur through box  30  unless prong sets  34  and  35  are mechanically statically stressed as by being plugged into a breaker box,  
         [0023]    no electrical transmission can occur through prongs  36  and  37  unless prongs  36  and  37  are also mechanically statically stressed as by being plugged into means  38 ,  
         [0024]    prong set  35  will be made electrically inert and isolated by appearance of a voltage on any part of prong sets  36  or  37 , and  
         [0025]    the breaker will be thrown by any change in the above conditions, or by disappearance of pre-existing voltage from any of said prong sets, except that when service is from means  20 , such service can continue during intermittency of voltage on prong sets  34  and  35 .  
         [0026]    The above just-said provides that switching from utility company service to inverter  20  service can only be accomplished with everything plugged in, and provides that no danger will appear to users if cable  25  is unplugged either intentionally or unintentionally. Other and usual interlocks are also part of means  30  and of means  27 , according to the prior art.  
         [0027]    The first  5  figures show hybrid self-propelled vehicles adapted to embody the invention. The next  5  figures show purpose-built embodiments.  
         [0028]    [0028]FIG. 6 shows a three-rail-car embodiment of the invention newly arrived and parked on spur  41  having car-bumper  42  at the end. Said 3-car embodiment comprises replaceable and modular coal-car  43 , an open-top rail car filled with coal  44  shown in the cutaway. Middle car  45  is a flatcar carrying hopper  46  feeding firebox  47  serving boiler  48  to operate steam turbine  49  to drive electrical generator  50 . all disposed and co-operating by means well-known in the prior art. Structural means not shown carry conveyor means  51  shown partly cut away, the cut away portion being denoted by outline  52 , said conveyor  51  having been carried in transit in the travelling position denoted by outline  53 , directly above car  45 . Conveyor  51  has just been relocated to position  52  in FIG. 6. Said cutaways of conveyor  51  and car  43  also show level belt conveyor  51   a  and sweeping bucket elevator  51   b  disposed as in the prior art to comprise conveyor  51 ; not shown, but present, are vacuum cleanup means of conveyor  51 . Environmental protection means comprising tarp and sealing means  54  and other apparatus not shown but well-known in the art are included herein.  
         [0029]    [0029]FIG. 6 also shows caboose car  55  which carries cherry-picker  56 , transformer  57 , switchgear  58 , control-house  59  and bucket truck  60  all in travelling position, although by now cherry-picker  56  has been operated to set conveyor  51  to position  52  from position  53  and to help place environmental protection means  54  as said. Cherry-picker  56  comprises main boom  61 , telescoping boom  62 , and insulator hanger cross-arms  63  and hook means  64  for general hoisting tasks, such as setting conveyor  51  as said, and will be used to pick up bucket-truck  60  by its headache rack  69  and set it on the ground as needed and as follows. Transformer  57  and switchgear  58  are disposed to co-operate by well-known means and through cable means  65 ,  66 , and  67  to provide suitable voltages as needed. Cable means  67  is spooled from spool means  68  as will be shown in FIG. 7. Truck  60  comprises headache rack  69  which comprises lifting adaptations for said handling by cherry-picker  56 . Truck  60  also has adaptations not shown to serve as a car-puller for replacing car  3  by another such coal car as needed. Truck  60 , being a bucket truck, is thereby adapted for electrical work to be shown.  
         [0030]    [0030]FIG. 7 shows the means of FIG. 6 deployed at another site and viewed along the axis of travel rather than broadside; the cars have arrived on rail line  71  which is not a spur, but a traffic-carrying line. and the view FIG. 7 shows car  55  sitting alongside and clear of line  71 , not on it, with car  55  carried by walking jack sets  72  to be shown further in FIG. 8. This offsetting allows line  71  to serve normal rail traffic. Cranes  56  and  60  are shown deployed to connect cable means  67  now partially unspooled from means  68  and hanging from insulators  63  in preparation for connecting into pre-existing transmission line  73  by means not shown, but comprising switching electrical tap means, to provide the benefits of the invention to loads along the line  73 . Cherry-picker  56  is thus disposed to serve as a transmission-line pole requiring no site construction, in addition to being useful in usual cherry-picker ways. FIG. 7 also shows jack legs  75  of jacks  78  with footings  79  all operated by walking spars  76 , i.e.  76   a  and  76   b . The footings  79  of spars  76   a  are shown lifted up in preparation for shifting further out of the way of track  71 , while the footings  79  of spars  76   b  are locked down and supporting the whole. For final founding, all eight footings  79  will be down and will thereby provide safe stable transmission.  
         [0031]    [0031]FIG. 8 is a plan of part of FIG. 7, showing walking jack apparatus  72  supporting rail car  55 , shown only in outline. Each of the two four-footed pieces  72  comprises U-shaped frame  74  and powering and control means  75  therefor mounted thereupon. Each means  72  further carries one each sliding spar boom means numbered  76   a  and  76   b  respectively, shown in the FIGS. 7 and 8 with  76   a  to the left and  76   b  to the right; of course, during walking the positions will alternate when booms  76  slide alternately through sleeves  77  to walk. Each boom  76  has at each end thereof demountable jacks  78  for urging footings  79  up and down for walking and for stable foundation after walking into position, all according to means well-known in the art. Not shown are detail of the pump means  75  or any part of structural racks and couplings on car  45  for carrying and mounting means  72  and components thereof since such are well-known in the art.  
         [0032]    [0032]FIGS. 9 and 10 show a semi-trailer embodiment of the invention which parallels the rail-car embodiment of FIGS. 6, 7, and  8 , just as FIG. 3 parallels FIGS. 1 and 2, and so FIGS. 9 and 10 will be elliptical, as was FIG. 3, since those skilled in the art will see the parallels and implement easily.  
         [0033]    [0033]FIG. 9 shows flatbed semi-trailer  80  travelling down a road. Trailer  80  is analagous to cars  45  and  55  in that it carries corresponding elements, but is different in that all are on a single flatbed, the whole being smaller and for smaller electrical loads, and adapted to liquid fuel. Trailer  80  carries motor fueling and environmental protection apparatus  81  mounted on motor  82  to drive generator  83  having transformer and hookup apparatus  84 . Trailer  80  has two folding articulated cranes  85  and  86  monted and folded crossways ath the rear and front respectively. Trailer  80  also carries belly-pad footing  87  carried high on links  88  centered below the width of trailer  80  for founding and walking as will be seen. Trailer  80  also carries two walking jack assemblies  89  standing astride means  82  and  83 , held there for transport by rack means not shown. Assemblies  89  are analagous to means  72  except that the presence of belly means  87  makes only one sliding spar  90  needed for each frame, rather than two each spars  76   a  and  76   b  respectively per jacking assembly as before. Spars  90  have jacks  91  with footings  92  at each end, similar to jacks  78  and footings  79  shown before.  
         [0034]    [0034]FIG. 10 shows trailer  80  and means thereof deployed at a site similar to the deployment of FIG. 2. The crane  85  has articulated boom manipulating fuel line  91  and fuel hookup and spill-protection coupling  92  to bring all into engagement with a fuel-tank truck not shown. Crane  86  with boom  93  is carrying electrical line  94  from spool means of electrical gear  84  preparing for connection to an electrical load at the site not shown. The footings  87  and  92  are shown all down, serving as foundations, having walked trailer  80  into the desired position. Cranes  85  and  86  were operated to lift frames  89  from the travelling position of FIG. 9 into locked engagement with trailer at and below each end of trailer  80  as shown in FIG. 10. Jacks  91  have operated to lift the weight of trailer  80  off of its wheels and front fifth wheel support and thereby enabled footing  87  to swing on links  88  into the lowered position of FIG. 10, and to be locked there by struts  95 . Then jacks  91  operated to lift footings  92  while the whole was supported on pad  87 , and the spars and jacks operated cyclically to walk the whole to the desired spot, as shown. The remainder of FIG. 10 is sufficiently parallel to the deployments of previous Figs. that implementation by those skilled in the art will easily follow.  
         [0035]    The FIGS. 1 through 5 show adaptations of hybrid vehicles, i.e. thermal engines driving electric generators which normally serve to drive the wheels, but adapted in the Figs to emergency power service. The FIGS.  6  throught  10  show custom-built embodiments and show fuel-conveyance and walking jacking foundation means, variations of which may be adapted to the hybrid vehicles of FIGS. 1 through 5 by those skilledd in the art. Each hybrid-vehicle embodiment employs a hybrid vehicle whose envisioned purpose was transportation, not stationary use, with ancillary power-supply a secondary consideration. Use of vehicles for stationary power provides great savings over emergency site-built power plants in that the motor-generator costs of the emergency power plant are largely unrecoverable if need goes away, but the hybrid vehicle is hardly diminished in value by short-term use as shown.  
         [0036]    Some hybrid vehicles known in the art employ the heat engine as a direct motive means as well as using the generated electricity to motivate the wheels. Some produce AC with the AC then being used to produce DC to drive the wheels. Some have large battery arrays and some have few and small batteries, and some travel on battery power alone at times. For the purposes of the invention, these are equivalent.  
         [0037]    The matter of scale arises wherein a quantitive difference becomes, at some scale, a qualitative difference. For example, in an old car without such interlocks as are now commonplace, it was possible to move the car a distance by engaging the clutch and pressing the starter button; sometimes mechanics would do this when the engine was disabled or overheated. In the sense of countable identifiable elements, the said old car is a hybrid vehicle having a heat engine driving a generator to charge a battery, and the car was motivated for a time by an electric motor (the starter); however, such literal readings do not make the car a hybrid vehicle in a reasonable sense, partly because the intent and recommendations of the manufacturers would discourage such use. Similarly, stationary power-plant use of the car can be discovered in the playing of the radio with the car doors wide open at a picnic, with or without the engine left running, or the use of headlights for emergency illumination by an ambulance crew at a wreck-site on a highway. Likewise, portable generators usually used by construction workers provide stationary and perhaps emergency power at a site, maybe to operate a refrigerator or a respirator; however, such use involves trailing and/or draping of perhaps orange extension cords around the site; such practices are restricted in some jurisdictions, and are inconvenient and a little hazardous as a matter of course. All of these readings of the prior art rely on literal logic which denies ordinary logic which recognizes that a change of scale sometimes embodies a change of kind; i.e., the foregoing literal equivalents are unequivalent; equivalents are much the same, but the said literal so-called equivalents are not much the same.  
         [0038]    [0038]FIG. 5 shows the outlet box  27  with its three-position switch  27   a , which when centered is off, and when to the right, as shown, disconnects the 110 v. outlets  28  and connects or empowers only the center 240 v. 1-phase outlet  29  into which cord  25  is plugged. When switch  27   a  is to the left it energizes only the now-empty 110 v outlets, each with one half of the 240 v. deliverable to outlet  29 , i.e. the output of inverter  20  is always 240 v 1-phase. Also, in FIG. 5, breaker body  30  is adapted to use in box  23  of FIG. 4, which has no rain cover, being in the garage of house  21 . This design is the service entry means of the invention, and has the advantage that many jurisdictions allow homeowners to change their own circuit breakers, and many howmowners feel comfortable doing so. In any case, even if an electrician-contractor or power-company worker installs the means  20 , the installation can be a one-time thing, since it is safely repeatedly switchably reconnectable to the car  19  through means  27 .  
         [0039]    Many variations of the means of FIG. 5 may be provided for various embodiments of the invention. A first obvious variation is a 120 v 1-phase variation to be used in the sockets  27  and plugged into a box such as box  23 , either alone or in pairs. A second obvious variation is the provision of a variation for a box with a rain-cover. Most such boxes are surface-mounted with knockout plugs accessible, so a variation of body  20  wherein screw-terminals connect to a rainproof electrical coupling, the whole comprising a rain-proof equivalent to body  20 , will be easily implemented. A similar rain-proof access to the means  20  or modification of means  20  for outdoor use are likewise easy to envision. Analagous means are easily envisioned, e.g. in means such as means  15  of FIG. 2. Many variations of such service-entry devices will be needed and provided by those skilled in the art, ranging all the way from simple double-throw switches with some circuit-protection and rain-protection up to uninterruptible power-supply-type couplings of means such as 15 to means such as locomotive  1  for automatic changeover in a matter of seconds. These variants on the service-entry means of the invention are generally equivalent and will be well-understood and easly provided by those skilled in the art.  
         [0040]    Another variation of the invention which may be illustrated by reference to FIGS. 4 and 5, but which differs substantially therefrom, is the embodiment wherein means equivalent to means  20  (call it means T) are not carried on the hybrid vehicle, but are more or less permanently installed on the floor or wall beside the breaker box  23  equivalent. In such an embodiment means T receive the usual DC power from a DC cord from the hybrid vehicle; said vehicle would only be altered to the extent of providing safe plug-in means, if altered at all. The rail equivalent would comprise an inverter in the building and a DC service entry to the building. These embodiments would be especially valuable in case of medical need, for example at a hospital in addition to the ubiquitous hospital emergency motor-generator sets, or at a house with an invalid resident with urgent need for power. Notice that high power could thus be made avaliable to a hospital, i.e. thousands of horsepower or many megawatts would be available from one or more locomotives.  
         [0041]    Concerning the self-erecting pole means, the Figs. and disclosure show knuckle-boom cranes or cherry-pickers of the prior art adapted by insulation, transport, and interlocking means to service of the invention. Envisioned is a plural array of such adapted truck-mounted boom cranes for carrying power over a distance, for example, across a street, waterway, or small building, in cases where there is a good distance between space for the invention and the demand. Additionally, knuckle-booms and cherry-pickers are valuable for such service, since, when not in service as power-transmission devices, they are quite useful and marketable for other service, just as the hybrid vehicles are, and give similar recoverability of investment. However, purpose-built other mobile and self-founding pole types will be seen to be equivalent for transmission-line service of the invention. One such type might use the familiar portable concrete traffic barriers which are used as temporary guardrails in highway construction as counterweights or foundations for such poles as a means of avoiding permanent construction according to the intent of the invention. Notice that such barriers also have the feature of high value recovery on completion of service, just as the cherry-pickers and locomotives are valuable elsewhere and for other purposes.  
         [0042]    Note that the invention envisions a turbine-electric or steam-electric equivalent of the hybrid vehicles, and also envisions coal, fuel-cell, gas, liquefied gas, or vegetable-oil fueled eqiivalents of the diesel and gasoline fuels as equivalent for the purposes here. Further envisioned here are equivalence of simple pad footings and crawler-tracked footings, said tracked footings being powered for lateral motion or not powered, e.g. being actuated by external towing means into place for founding. Another equivalent walking foundation means is the straddle truck, either with crawler tracks or with wheels. Straddle trucks could be made to lift a locomotive off of the railroad and hold the locomotive founded near a transmission-line or service entry which could not otherwise be approached without obstructing rail traffic. So displacing the locomotive, thus making it a stationary engine, would reduce crew size requirements.
