Aren't there more than bikes?
on September 3, 2012
I loved that the book told me all about different human powered events all over the world, and the description of how electricity is made was basic enough for me to understand. However, all of the devices suggested in the book involve bicycles. Maybe it's true that it takes a pedal to make something run or make electricity, but I was thinking of other ways to power things.
The book is very well written and friendly.
