To set the scene, currently Google and Facebook are arguing over who would own the technology that could one day provide wireless internet to the most remote areas of the world. At that same time numerous engineers and designers compete to make the best and most efficient, compact, easily transported, solar …
Italy is known for its plans to develop photovoltaic power as one of their main sources of energy. Having such a wide experience in solar power harvesting, several issues arise regarding the solar panels’ maintenance. Every PV plant has a sensor verifying the quantity of light arriving at its location at any given moment during the day.
Scotland built a 180 m tube they call “The Sea Snake”, that will capture the waves’ movements and energy and transmit it via subshore cables to the land.
IBM, through its “Big Green” – “Battery 500” project, aimed to produce a battery for an electric car that would be able to carry a family-sized sedan up to 500 miles, spotted the lithium-air (STAIR) invention as its goal, and predicted that they could improve the STAIR battery further with the nanoscale semiconductor manufacturing techniques they possess.
Too often, regardless of the energy sources being used, the GSM transmission towers’ power fails, because of various reasons: theft, heavy rain/snow, disturbances in the grid lines. Helix, a San Diego-based wind company, is working on a wind turbine that is designed to power base stations in hard to reach, remote locations from Africa and the US.
Researchers from Purdue University discovered precisely how fluid boils in capilary cooling sytems, and that by designing a system by using those rules they got a much more efficient heat transfer between the object to be cooled and the liquid.
Oregon State University engineers have innovated a new nanostructure film technology that they can deposit on any surface and reduce the reflectance of light. Their technology should perform better and have a lower price.
Yet another efficiency record has been established for mass-producible solar cells: 23.4%. The Fraunhofer Institute for Solar Energy Systems (ISE) from Germany succeeded to manufacture a single-crystal silicon solar cell of a thin p-type semiconductor layer residing on an n-type semiconductor substrate. The solar cell’s area is 2x2cm.
An Oregon-based company, Arcimoto of Eugene, designed their fully electric vehicle capable of reaching no less than 190 mpg, if we take mpg as an energy reference.
Engineering assistant prof. Dane Morgan and Ph.D. student Edward (Ted) Holby, from the University of Wisconsin-Madison have discovered that making the fuel cells from very small platinum nanoparticles decreases their lifetime. Making them bigger is, though, better.
