10 December 2009—This week at the International Electron Devices
Meeting (IEDM), in Baltimore, Md., Cornell University engineers
presented research that shows progress in powering cybernetic organisms
with a radioactive fuel source.
Electrical engineering associate professor Amit Lal and graduate
student Steven Tin presented a prototype microelectromechanical systems
(MEMS) transmitter—an RF-emitting device powered by a radioactive source
with a half-life of 12 years, meaning that it could operate
autonomously for decades. The researchers think the new RFID
transmitter, which produces a 5-milliwatt, 10-microsecond-long,
100-megahertz radio-frequency pulse, could lead to the widespread use of
radioisotope power sources.

New Wind Turbines Are Designed To Look Like Trees
Business Insider
A lot of people moan about how wind turbines make the countryside look bad. Clean, renewable energy often comes at a price. Enter "turbine trees" — one company's way of tackling the issue of aesthetics in sustainability.
Designer NewWind R&D has created a "silent" turbine called the Tree Vent that is supposed to blend into the landscapes which house it. It's a 36ft-tall structure made of steel with 72 artificial leaves.
