Conduit hydroelectricity. Conduit hydroelectricity (or conduit hydropower) is a method of using mechanical energy of water as part of the water delivery system through man-made conduits to generate electricity. Generally, the conduits are existing water pipelines such as in public water supply. Some definitions expand the definition of conduits to be existing tunnels, canals, or aqueducts that are used primarily for other water delivery purposes than electricity generation.

Historically, electricity generation from water pipelines was rare because the water would have been pumped by other engines in the system prior to the intake of water turbines to generate electricity. The energy generated from the turbines would have been offset by the power used in pumping, canceling out the power generation benefit. However, there have been renewed interests to apply this method to recover energy when there is a need to reduce pressure in the water supply system that is normally done through pressure reducing valves. The conduit hydroelectricity generation in this case can be done by replacing the pressure reducing valves with small turbines and electrical generators.

Since 2008, there has been considerable technological development in off-the-shelf "“water-to-wire” turbine technologies including reaction, impulse, and hydrokinetic turbines that target the sub 1-MW in-conduit hydroelectric market."

Portland, Oregon uses conduit generation in its water pipes. The Imperial Irrigation District had plans for 14 new conduit hydropower projects in 2016. 

In 2013, the US had "a total of 236 FERC authorized conduit exemption projects."

Damping capacity. Damping capacity is a mechanical property of materials that measure a material's ability to dissipate elastic strain energy during mechanical vibration or wave propagation. When ranked according to damping capacity, materials may be roughly categorized as either high- or low-damping. Low damping materials may be utilized in musical instruments where sustained mechanical vibration and acoustic wave propagation is desired. Conversely, high-damping materials are valuable in suppressing vibration for the control of noise and for the stability of sensitive systems and instruments.

Overview 

A large damping capacity is desirable for materials used in structures where unwanted vibrations are induced during operation such as machine tool bases or crankshafts. Materials like brass and steel have small damping capacities allowing vibration energy to be transmitted through them without attenuation. An example of a material with a large damping capacity is gray cast iron. 

An understanding of this effect can be gained from observation of a stress-strain diagram with exaggerated features. The units of stress are force per unit area, while strain has units of length per length. Any area covered by integrating each instant of a loading and unloading cycle will then be in terms of force times length per volume, which is equivalent to energy per unit volume. This energy represents the amount of mechanical energy being converted to heat in a volume of material resulting in damping.

Sri Lanka Railways S10. Sri Lanka Railways S10 is a class of Diesel-electric multiple unit (DEMU) train set built for Sri Lanka Railways by China South Locomotive & Rolling Stock Corporation and imported in 2008. Fifteen S10 DEMUs were ordered to strengthen commuter services on crucial commuter lines.

Technical specifications
At nearly  the Class S10 provides power outputs to give high rates of acceleration and passenger capacity.

The engine is equipped with common rail diesel injection technology which helps to control internal combustion correctly. The alternating current which is produced by the generator is converted to direct current and transferred to traction motors. A computer system is installed to control most of the activities of the engine. The driving cab consists of a desk type control stand and touch-sensitive visual display unit. The Class S10 can also be used for multiple unit working and up to three train sets can be coupled with one another.

The Class 10 possesses only Third class interiors as it is used exclusively for commuter services.

Operations
The Class S10 can be used on any line except the Kelani Valley Line, owing to the great length of the coach bodies being unable to traverse the line's tight curves. S10s are commonly used in stopping passenger services.

Zoetron therapy. Zoetron therapy is an ineffective cancer treatment based on a large doughnut-shaped electromagnetic device (the "Zoetron machine").

The device was marketed by the CSCT company (standing for "Cell Specific Cancer Treatment", an alternative name for the therapy). It was claimed to detect cancer, and to "destroy cancer cells without harming adjacent normal cells". The promotion of the machine was backed by the publication of a number of misleading case reports.

In 2003 the U.S. Federal Trade Commission took action against CSCT in coordination with the Canadian and Mexican authorities, alleging that the company had been falsely promoting its device as a cancer treatment online, and charging for its use in cancer clinics in Tijuana, Mexico. In 2005 criminal charges were bought against the company's officers for making false or misleading claims about the worth of the Zoetron machine.

Patients being treated with the machine had been asked to pay up to US$15,000 in advance, however the treatment had no therapeutic value: on inspection the device was found to consist of weak magnets that could have no effect on cancer. Quackwatch states: "There is no scientific evidence or reason to believe that exposure to weak magnetic fields will kill any cells or that cancer cells accumulate iron or respond differently than normal cells to a magnetic field."

Karl A. Grosch. Dr. Karl Alfred Grosch (1923-2012) was a rubber industry scientist noted for his contributions to understanding tire friction and abrasion.  Dr. Grosch is the developer of the LAT 100 Abrasion tester that is used widely in the tire industry to evaluate the friction and wear properties of rubber compounds.

Personal

Grosch was born in , today  An der Heide 11, 07387 Krölpa/Trannroda Thuringia, Germany, on February 16, 1923, died July 15, 2012.

Grosch served in the German military during World War II, and was captured by the British as a prisoner of war.

Education

He received a B.S. (Special Physics) from the University of London in 1958, and a Ph.D. (Science) from the school in 1963 under the supervision of David Tabor of Cambridge and L.R.G. Treloar of Manchester University with the title Friction and abrasion of rubber.

Career

In 1955, Grosch started his career as a research assistant at the MRPRA, under Adolf Schallamach.  Grosch helped establish that rolling friction and grip on dry roads are governed by the viscoelastic properties of rubber.  In 1963, he was named principal scientific officer.

In 1969, Grosch joined Uniroyal in Germany, working there until his retirement in 1988.

After retirement, he developed the LAT 100 laboratory friction and abrasion tester, which is marketed by VMI Holland BV in the Netherlands.

Cota (power). "Cota" is the name for a patented technology designed to deliver wireless power, it was developed by Ossia Inc.

The technology sends radio waves at a frequency of 2.4GHz, which are then received by a receiver device equipped with a Cota chip. The receiver converts the radio waves into usable electrical power, which can then be used to charge batteries or power electronic devices.

One of the key advantages of Cota is that it can transmit power over distances of several meters, even through obstacles such as walls and furniture. This makes it a potentially useful technology for powering devices in homes, offices, and public spaces without wires or cables.

Features 
Cota can detect the position of a power receiver within its network and focus a signal to only that position, enabling up to 1 watt of power to be transmitted wirelessly. Since the charging hub can detect, focus, and send the signal to a specific point in the 3-dimensional space, there is no risk of injury compared to other means of wireless power, such as microwave power transmission. Additionally, since Cota uses the same frequency range as Wi-Fi, its range is about 30 feet, an improvement over inductive wireless standards such as Qi which typically have a range of only a few centimeters.

FCC Approval
In June 2019 the Federal Communications Commission granted Ossia equipment authorization for the Cota wireless power system (Cota Transmitter and Receiver), approving its wireless power delivery and data communications under Parts 18 and 15, respectively, of the FCC's rules and certifying the system to be marketed and sold in the U.S.

Overview & History
SpaceHub Southeast was cofounded in Atlanta, Georgia, in 2012 by Beau Martin and Meryl Mccurry with the mission to provide access to the upper atmosphere to the general public.

PongSat Program

PongSat stands for ping-pong satellite and consists of any experiment that can be contained within a ping-pong ball. Projects range from things as simple as a marshmallow to programmed circuit boards. Not all PongSats are scientific, some are purely artistic. The program does have restrictions:
 Anything that sticks out of a PongSat must be pre-approved
 No volatile chemicals
 No combustion reactions etc.
 May not be heavier than 3 oz.
 Any device that emits a radio signal must be pre-approved

Partnerships

ZPM Espresso

Space Hub Southeast and ZPM Espresso partnered in 2013 to send the first whole bean espresso coffee into space. The partnership resulted in special balloon launch carrying one pound of whole bean coffee to the upper stratosphere, which was then brewed and consumed. ZPM commented that the espresso tasted 'Gross' and lacked flavor.

The Westminster Schools

The Westminster Schools has served as the launch venue for the PongSat launches since 2012.

TinyCircuits

TinyCircuits produced the 'TinyDuino' Board, "an Arduino compatible board in an ultra compact package". Space Hub Southeast has worked with TinyCircuits in making these board available for free to select PongSat students. The Space Hub Southeast TinyDuino Scholarship provides students with the opportunity to apply for a TinyCircuits TinyDuino, free of charge.

Omnilink

Since 2013 Omnilink has provided Space Hub Southeast with an OM210™ system that they use to track the high altitude payload. The device is extremely durable and has been unaffected by the harsh environment. Space Hub Southeast has been featured on Omnilink's home page.
