The ElectraFlyer C is a carbon fiber-shelled mini plane that runs on electricity, and it also looks like a lot of fun. It's a mash-up of a commercially available glider body and a lightweight battery and motor/propeller assembly. It can fly for 90 to 120 minutes at up to 90MPH, and you can recharge it in about six hours from a regular 110 volt outlet for about 60 cents. Oh, and it's received its airworthiness cert, meaning it's perfectly legal. [ElectricFlyer via Wired]
