The empowering people. Award recognizes creative technological solutions for sustainable improvment of basic services. In 2016, the third prize was awarded to aQysta for the Barsha Pump – Hydro-powered Irrigation. Developed to help farmers, this waterwheel utilizes the energy from the flow of rivers and canals to pump water, regardless of the flow velocity. The device, which can pump long distances, is not only affordable but uses indigenous materials. It needs little maintenance and does not require any fuel or electricity to work. This ensures that the pump has no operating expenses.

Context: Nepal, high mountains and farmers breaking their backs while carrying buckets of water from the brook to their fields.
Solution: pump the water from the brook to the field, using hydro-power for the pumping, eliminating expensive fossil fuel. Pump and generator combined in a single device.
Inventors: Pratap Thapa (Nepal) and Fred Henny, working together in Aqysta, Delft, the Netherlands. Mr Thapa meanwhile operates in Nepal and mr Henny runs the business in Holland.
Installed base: 50 pumps world-wide and 40 in Nepal.
Required flow: 0.5-2 m/s, generating 1.6 bar air pressure
Max. elevation: 20 meters
Flow rate: 0.5 liter/second
Application potential word-wide: 250 million hectare agricultural soil
Price: 2,000 euro (diesel pump cost few hundred euro, but with the Barsha pump you have 10 years no fuel cost, resulting in 70% overall pumping reduction cost)
Potential new markets: Colombia, Indonesia, Ghana, Guatemala and Zambia
Innovative aspect: oval rather than circular hose diameter, allowing for higher pressure buildup

Product comes as a kit from parts produced in Europe.
Nepalese government wants to subsidize 200 pumps.
Larger prototype under development for Spain and Turkey.
Winners Siemens Empowering People Award.
