Non-stop solar flight

So interesting already. Not around the world, but aloft for over 7 days over the U.S., the Zephyr broke the previous record of 30 hours. Soon, the record will be years. For science, and the earth, this is fantastic!

Successful round the world, while dark, solar flight

Solar Impulse, the completely electric, solar powered plane, completed it's maiden overnight journey yesterday. Still to go: transatlantic, then the world.

Someday we'll see autonomous electric cargo shuttling around the world, safer, cheaper, and cleaner. When these become passenger planes, I hope I'm still alive.
