Hydrogen-Powered UAV Breaks Record

Uav10 It might not sound like much, this 78 mile flight, but the recent journey by the Pterosaur Unmanned Aerial Vehicle (UAV) was actually a record-breaker.

Powered by hydrogen fuel cells, the Pterosaur flew 28 miles farther than the previous record for micro-UAVs, which weigh in at around 11 pounds or less, and its developers say it only used a fraction of the fuel in its tank. Eventually they claim it should be able to go 310 miles. Singapore-based Horizon Fuel Cell Technologies developed the propulsion system in conjunction with scientists at several U.S. universities.—Gregory Mone

Big Wheels for Little Cars

Chemists build the world´s smallest auto dealership, molecule by molecule. No toy models, these cars actually drive

The most prolific car manufacturer on the planet resides in a Rice University laboratory in Houston, where chemist James Tour and his colleagues have built one trillion trillion nanoscopic cars. The tiny four-wheeled vehicles are only four billionths of a meter wide-25,000 of them parked side by side would be about as thick as a piece of paper. Not just another nano-gimmick, Tour´s cars could one day carve tiny channels in silicon, creating more-powerful computer chips.
