New "nanoantenna" material sucks heat from any source to cool devices, generates electricity
We're always up for another way to harvest energy from the sun, but this new nanoantenna material developed by the DoE's Idaho National Laboratory makes solar panels seem a little passe. The material, composed of tiny gold antennas set in polyethylene plastic is tuned to gather 80 percent of energy from infrared rays in its production version, and can gather energy from the sun, earth, or even your PC's warmth. The antennas can be tuned to different parts of the infrared spectrum, and the thin material can be sandwiched together to cover the full desired range. Unfortunately, the resulting current generated alternates at rates too high to be converted to DC with current technology -- new manufacturing processes will needed -- but once that problem is solved, nanoantennas should easily best solar cells in efficiency and production costs.[Via DailyTech]
NYC Dept. of Education suspends Mac orders pending wireless issue fix
Apple Insider is reporting that the New York City Department of Education has put all shipments of Macs to schools on complete hold while they're apparently waiting for Apple to fix a Wifi connectivity issue with OS X (which should be fixed with the 10.5.3 update). And Apple is apparently scrambling to get it worked out -- they've sent an apologetic email to faculty and have asked schools to try and separate any orders of computers that won't need wireless (that will use a regular ethernet hookup) to ship now.Unfortunately, there's no hint of exactly how many Macs we're talking about here, but if this is a substantial number of computers, and word gets out causing other organizations to delay shipments as well, Apple will feel more and more pressure to get the problem fixed ASAP. Bad news for the kids who want Macs in New York City (that's the DoE's seal on the right, in case you didn't recognize it), but good news for anyone else having this problem -- Apple's working hard on a fix.Thanks, Rich!
