A novel fabrication technique developed by a University of Connecticut engineering professor could provide the breakthrough technology scientists have been looking for to vastly improve the efficiency ...

The upper part of the structure suspends an array of dishes that acts as a surrogate satellite, focusing sunlight, converting it to energy and sending it down to the ground, where a rectenna dish ...

Researchers built a small, flexible device that harvests wi-fi, bluetooth and cellular signals, and turns them into DC electricity. Christopher Intagliata reports. One of the biggest drawbacks to ...

(a) Outdoor OMEGA-SSPS ground demonstration and verification system, and (b) prototype of OMEGA-SSPS ground demonstration and verification system. SE: sun energy; TX: transmission antenna; RX: ...

How did a Georgia Tech team overcome certain limitations to develop an antenna that harvest energy in the 28-GHz band? The key role played by the Rotman lens in making it all happen. Test results ...

It's been the dream of visionaries for decades: Sunlight converted into direct current to use for recharging emission-free electric cars. Photovoltaic cells offer that capability today, but now ...

The efficiency of optical rectennas made from carbon nanotube diode arrays can be improved by adding a double insulator layer to them. Doing this also makes the devices stable in air for the first ...

Engineers at the Georgia Institute of Technology have developed a new form of technology that combines two well-established technologies — a rectifier and an antenna — to create a device capable of ...
