Pedal Pump On YouTube.
Around the world communities struggle with access to their most important commodity -- water. When you're not plugged into the grid, providing water becomes a daily survival challenge. But we don't have to be plugged in to pump. Instead of relying on fuel-burning generators or resource-consuming infrastructure, we can get water with human power. The Pedal Pump is a portable and versatile water pump for off-grid applications. I built the pump using salvaged materials and off-the-shelf plumbing parts to make it easy for anyone to duplicate with minimal tools. The core of the pump is a piston and cylinder from a small air-cooled engine -- in this case a lawnmower -- paired with the crank arms and pedals from an old bicycle. With each stroke the piston pulls water up through a one-way valve, into the cylinder, and out another one-way valve. And with leg power instead of a hand pump, you can pump a lot longer. The pump could provide drinking water from a well, pump from a river for irrigation during the dry season, and remove water from flooded buildings during the rainy season. There it is -- a simple pedal-powered water pump with great potential. Globally, water is our most valuable resource, and for many communities the availability of water determines survival. When we innovate, we live.
