harrymcc writes “On August 3, 1977, Radio Shack announced its TRS-80 microcomputer at an event in New York City. For the next several years, it was the world’s most popular PC — but it never got the respect it deserved. (I still wince when I hear ‘Trash-80.’) Over at TIME.com, I’m celebrating the anniversary with some reflections on the machine and why it was so underappreciated.”

judgecorp writes “Everlasting green energy for RF tags and other low-power devices could be possible as scientists have harvested energy from ambient radio waves using cheap antennas printed by an ordinary inkjet. The scientists, from Georgia Tech, started at 100MHz but have now produced systems which scavenge power at up to 60GHz, allowing them to draw power from most of today’s major radio technologies.”
