By David Greenfield – A number of efforts are currently being employed across industries to harvest energy typically lost during production operations. A number of these projects involve energizing low-power devices, such as sensors, through capture of wasted energy from vibrations or heat dissipation. But that still leaves a massive amount of energy being released by industrial systems that remain uncaptured for greater use.
To help address this, the German Federal Ministry of Economics and Technology is funding a project at Deprag Schulz GmbH & Co. (a supplier of air motors) to capture excess process gas for energy generation. Of course, energy recovery from excess process gas in not a new idea, but Deprag Schulz’s new project does add a new twist. The Deprag Schulz project involves converting small amounts of residual energy (5 -20 kilowatts) directly into electricity using a small generator. more> http://twurl.nl/ulmrxo
R&D Mag – Like atomic-level bricklayers, researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are using a precise atom-by-atom layering technique to fabricate an ultrathin transistor-like field effect device to study the conditions that turn insulating materials into high-temperature superconductors.
“Understanding exactly what happens when a normally insulating copper-oxide material transitions from the insulating to the superconducting state is one of the great mysteries of modern physics,” said Brookhaven physicist Ivan Bozovic.
Superconducting FETs might also have direct practical applications. Semiconductor-based FETs are power-hungry, particularly when packed very densely to increase their speed. In contrast, superconductors operate with no resistance or energy loss. Here, the atomically thin layer construction is in fact advantageous—it enhances the ability to control superconductivity using an external electric field. more> http://twurl.nl/fjhmbr

NASA – As Labor Day arrived in 1965, the hard work to construct Launch Complex 39’s Pad A was complete, and the pad was ready to be turned over to NASA. Designed to launch the Apollo Program’s Saturn V rocket, Pad A was the first of two planned pads in the complex to be completed. Construction began in November 1963. The prime contractor was a joint venture of Blount Brothers Construction Corp. and M. M. Sundt Construction Co.
Looking like a giant erector set, is the construction of the payload changeout room for the Space Shuttle Program at Launch Pad 39A. It allows the capability of loading the shuttle vertically, and making installation or removal of payloads at the launch pad possible.
This is one of several concepts prepared by Kennedy Space Center’s 21st Century Space Launch Complex Program planning team depicting Launch Pad 39A reconfigured to support a number of heavy-lift, commercial crew or other launch vehicles. more> http://twurl.nl/0txdbn
