This Mini, Portable Wind Turbine Could Charge Your Phone Or Power Your House - 2 views

The largest size (2500 watt) could provide enough power for a small house (though would obviously need backing up). The 1000 is good for RVs and boat owners, the Agustssons say, while the smallest 50 watt one is right for USB devices and laptops. The turbines can also back up electric cars when the grid isn't available.
