Looking for a good idea to add something to your upcoming outdoor green event? Want to make an existing event even more interesting and green?
Check out The Biker Bar - a portal power generation station that's powered by the crowd. And some bikes. There's even a rolling stage, whose energy comes from the very pedals that it's pulled by.
If your office were powered in this fashion, you could eat doughnuts all day long. From @gianttree_jeff
