The 'Wind-Helmet' is a dome-saver that one-ups most clean energy designs by harnessing energy from the wind--like a head-mounted windmill--as you ride your bike or motorbike. It's a concept entry by Wai Hoong Leng for Core77's Greener Gadgets competition.
Wearing the 'Wind-Helmet' lets you charge your cell phone with the same wind you feel on your face while whizzing down the street on your bike. Can't get much greener than that!
Implications - This helmet is perfect for the many people who tend to forget to charge their phone before heading out for the day. Not only is this gadget great for the environment, but it also allows bike riders to stay connected with friends and family at all times of the day.
