Default pulser pump video (Simplest pump in the world)

So why not just cut & paste an extract?
Eg

capacity.

WORKING MODEL Approx. Flow 260 liters per minute of water , head 0.5
m, going 2.5m deep and pulsing to 3.6 m gave 4 liters per minute. The
same setup gave 1.5 lpm at 5 meters high. This was with a split process
pump using 10 cm (4 inch) pipes for the stream water and using 19 mm
(3/4 in) for the pulsed water delivery. The efficiency decreases like
this as one pumps higher. On the other hand, 2 stages to 7 meters will
give about 2 liters per minute with the same setup. Going deeper also
increases the efficiency. Perhaps you have an abandoned well that you
can use?

So input power 260 x 0.5 x g/60 joules

Useful output 4 x 3.6 x g /60 joules

Efficiency 11%

At 5m lift it's 6%.

It's not rocket science.
