Pulser pump New video 2011
The pulser pump combines a low pressure tromp (discovered in Italy in the 16th or 17th century with a low pressure airlift pump. This combination has no moving parts and can be used to get power from little streams or rivers. The type of airlift that the pump uses is called plug flow or slug flow. This is NOT the same as in typical airlift pumps. The pump isn't just for pumping water. Other uses are possible too. The pump could be very useful in certain situations (it is just pipes joined together) where the cost of typical hydroelectric power machinery is impossible to justify. It can also be a new "first step" on the ladder of development.
