MMKamp ’10 hosted Ralf Schreiber with workshop on wind and sun powered instruments. Workshop was focused partially on recycled plastic botlles that were used as wind mills that were introduced as a way to power machines.

This is short video showing a concept with 4 bottles on fixed pivot (pivot moves together with the propellers, for the difference where propellers move and pivot is static).
