A Texas company has figured out how to keep bread fresh for over 60 days, in the form of a huge homogenized microwave cannon.
Duke University scientists David Smith and Nathan Landy have achieved "perfect invisibility" — something that researchers around the world have been working on for years. Up until now, cloaking has been incomplete as each test has reflected some light back and made the object appear only partially hidden.
Most military weapons systems rely on sophisticated electronics for control, so if you can somehow knock out the circuits, the weapons will become useless. A new type of missile tested last week by Boeing and the USAF exploits this vulnerability, by zapping selected buildings with microwave energy so powerful that all electronics inside will stop working.
Microwaves aren't very smart. It generally has no idea what you're trying to heat up, and if it's (say) a burrito and not (say) a frozen turkey, a bunch of extra microwave... waves... are going to waste. This blue box can suck up all of those spare microwaves and turn them back into electricity that — wait for it — can power your microwave again.
Improvised Explosive Devices, or IEDs, are a huge problem in Iraq and Afghanistan. How should the military take care of them without damaging any people or equipment? The new strategy: microwaves.
The Japan Space Agency, along with Mitsubishi Electric Corp. and IHI Corp., are getting even closer to next big thing: harnessing the power of the sun with a solar collector in geostationary orbit. Now there's cold hard cash involved. The...
