It is claimed that it is capable of pumping water up to a height of 25 meters, with a maximum flow of one liter per second. The moving water turns the wheel which in turn uses a spiral mechanism to compress the air. That air propels the water through a connected hose that lifts the water up to the fields, a European union climate innovation initiative that recently selected a jury of employers, financiers and entrepreneurs to award funding to what they considered to be the best clean technology innovations from Europe in 2014.
Climate-KIC, a climate innovation initiative of the European union, recently selected a jury of entrepreneurs, funders and businessmen to award funding to what they felt were the best cleantech innovations in Europe in 2014. First place was taken by the Dutch start-ups in a Delft University of Technology spin-off company that manufactures what is known as the Barsha irrigation pump. It can reportedly increase crop yields in developing nations by up to five times, yet it doesn't require fuel or electricity to run.
Although the Barsha pump, in Nepal called the rain pump is a new product, it is based on a very old design that has its origins in ancient Egypt. The pump itself is essentially a water wheel on a floating platform, which is moored in a nearby river with its moving waters. The hydraulic energy of the water turns the wheel which in turn uses a spiral mechanism to compress the air. That air drives the water through a connected hose to the fields.
It is claimed that it is capable of pumping water up to a height of 25 meters, with a maximum flow of one liter per second. According to its designers, it has zero operating costs, only the movement part, the pump can be built with locally available materials, and should provide a return on investment within one year of use by saving diesel energy, they claim that the pump is designed for about 10 years. Of course, it also doesn't create emissions.
The first Barsha pump was created in Nepal this July, and a new business was established there to manufacture and market the devices. The plans foresee a similar development in Asia, Latin America and Africa.
