Pint-sized Wind Power
Courtesy Aurea Technologies
A camper charges a phone with wind power.
If you’re planning a camping trip, you may want to pack a Shine. This small portable device uses wind to generate electricity. It can power small electronics like smartphones.
Wind power is a type of renewable energy that doesn’t create pollution or use fossil fuels. Often, wind power requires huge stationary structures called wind turbines. But Shine users can produce their own clean energy as long as the wind is blowing!
The Shine works in wind speeds up to 28 miles per hour (mph). A wind turbine’s top wind speed is 55 mph.
Is a wind turbine’s top wind speed more or less than twice that of the Shine?
