Barsha pump provides irrigation water, but doesn't need fuel

• newatlas.com by Ben Coxworth

Taking first place was Dutch startup aQysta, a Delft University of Technology spin-off company that manufactures what's known as the Barsha irrigation pump. It can reportedly boost crop yields in developing nations by up to five times, yet requires no fuel or electricity to operate.

Although the Barsha pump (Nepalese for "rain pump") is a new product, it's based on a very old design – it has its origins in ancient Egypt.

The pump itself is essentially a water wheel on a floating platform, that's moored in a nearby flowing river. The moving water rotates the wheel, that in turn utilizes a spiral mechanism to compress air. That air drives water through an attached hose and up to the fields.
