A couple of my favs:
- The Aquaduct a tricycle for transporting water from a distant (3rd world?) water source and purifying it along the trip. It converts to a stationary mode to continue filtration. This solves a real problem in many parts of the world.
- the Pedal Powered Mobile Call shop. This great little idea is not only a pedal powered application,it’s a full fledged business model.
- a Pedal-Powered Fridge
. Another real-world application here, this could potentially keep vaccines cool off the grid.
