Who would think that a "carousel in Paris" and "renewable energy" would be in the same sentence? On July 6, 2011, this interesting carousel was introduced, a carousel in which at least a portion of the power is generated through "pedaling" the horses and other vehicles. Marcel Campion along with the assistance of Pascal Pouzet created this carousel of "renewable energy" from an existing merry-go-round. For those who do not ride the carousel, there are several positions with recumbent bikes off to the side to help generate the power. Additionally, there are photosensors, solar cells, a small windmill... and a more traditional motor to assist when little legs do not pedal quite fast enough to turn the gigantic carrousel.
Oh, and the bonus is that structure looming in the background...
