Pratap Thapa has designed an efficient and inexpensive solution that allows water to be pumped without relying on fuel. The Barsha pump, developed by the Dutch company aQysta, of which Pratap is a co-founder, is a waterwheel placed on a platform floating in a river that uses the kinetic energy of water to pump water through pipes.
For their design, they were based on technologies developed in ancient Egypt.
Its operation is simple, does not use any type of fuel or electricity for its operation, uses the kinetic energy of the water flow to move the wheel. Each time the wheel spins, it will collect some water and air, and the pressure exerted by this air is what will then allow the water to be forced out through the pipes into the field.
It is a product suitable for small farmers, with few hectares and whose geographical location has little access to electricity or fuel.
Some of its main features are:
- It is able to pump water up to 25 meters high.
- You can irrigate between 0.5 and 3 hectares.
- It is capable of pumping up to 45,000 liters / day.
- It does not use any type of fuel or electricity for its operation.
- Savings of up to 70% of the total cost of irrigation (pump plus fuel), the investment can be amortized in just 2 years.
- It can work 24 hours a day.
- Quick and easy installation.
There are currently 35 such pumps in service in Nepal, Indonesia, Turkey, Zambia and Spain.
The The only one in Spain is in the Cortijo San Rafael, from Villanueva de la Reina, Jaén.
In 2014, he won the first prize of Climate-KIC, a climate innovation initiative of the European Union.
