We have been over-looking the cheapest, most efficient and sustainable energy source out there– KIDS PLAYING!  The PlayPump is an incredibly simple but effective invention that helps people in Africa access clean drinking water. While children are playing on a merry-go-round up to 1,400 liters of clean water can be pumped into a tank that stands seven meters above the ground. The tank’s walls are used to place ad billboards while two sides are reserved for educational messages. The revenue from ad-sales is put into the maintenance of each pump.  Talk about "Meet me where I am".
