New Antennae Harvests Lost Heat Energy

July 12, 2018 | Leave a Comment

Sandia National Laboratory researchers have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power. The rectenna, short for rectifying antenna, is made of common aluminum, silicon and silicon dioxide using standard processes from the integrated circuit industry. Converting electrical power to heat is easy. […]

A New Solar Power Antenna

March 1, 2013 | Leave a Comment

University of Connecticut (UC) engineering professor Brian Willis has developed a novel fabrication process called selective area atomic layer deposition (ALD) to fabricate a working solar power antenna device.  Solar power antennas are incredibly small nanosized antenna arrays that are theoretically capable of harvesting more than 70 percent of the sun’s electromagnetic radiation and simultaneously […]
