Solar Impulse

[collecture]

I'm taking the kids to see this on Tuesday as it has made its' first stop here in Phoenix. Looks pretty neat!
You have to register, but it is free. It has a wingspan like a 747, but weighs no more than a car.
Also stops in Dallas, then St. Louis, Washington D.C. and finally New York.
