Hi there
I once saw in California, a specific kind of solar water pump.
It worked on the same principal as this one on the link, but it was for serious pumping
This one is just a toy;

I need its big brother.
Solar power charges a capacitor, then when the capacitor fires, that drives a piston to pump water.
The more sun, the more times per minute the piston fires.
The piston is the only moving part (or maybe it is a diaphragm)
I think this is a great use of solar power, with no battery storage.
It would suit my purposes very well and i want to buy one.
Unfortunately I can not find it anywhere on the web.
Does anyone know what i am talking about?
I need to find the supplier.
Many many thanks - Mark

Is this the type solar pump you are looking for?
