There’s been many solar research models lately. Many are trying to get aircrafts to fly around without nothing but power from the sun. This is actually a remarkable research, as who knows, in the future we might be flying around using cute looking aircraft powered by solar energy. Totally green indeed! It’s a great thing to know that everyone’s getting into the ‘save Mother Nature’ move.

The Zephyr drone from QinetiQ will be running around again, with a new record that it hopes to blow away. 7 days in the air, and counting! The craft, which took off from the Army’s Yuma Proving Ground in Arizona last Friday, is being billed as an “eternal aircraft,” one that can stay in the air for extremely lengthy periods of time for use as recon and communications platforms. The earlier world record for a UAV was set by NASA’s Global Hawk, which stayed aloft for 30 hours and 24 minutes.
