That is an awesome pump. But if you want a true earth-moving experience then go to Cobdogla (the South Australian riverland) and take a look at the world's only operational Humphrey Pump on one of the days when they fire it up. Simply amazing.

Here's a page on how it works: http://www.angelfire.com/ak5/energy21/humphreypump.htm

Wow, I've never heard of one. Thanks for the link Mark. It might take me a few more reads to get my head around it though. There were some really smart people for their times. Humphrey appears to be one of them. Not sure how the residue from combustion would impact water quality, but might be minimal due to the volumes involved.

I had heard of the Humphrey pump but never seen details of operation. It is not mentioned in several of the textbooks I have about pumps and pumping.
Worth googling "Humphrey pump" if you are intrigued. Also try "fluidyne".

Greenpeace and FAO are trying to resurrect this idea for small pumps in impoverished areas of India.

Thanks Mark for the link.

These pics are of a bush fire, on the edge of a lake, near our home. They were taken a couple of years ago.

View from our upstairs balcony.

The water chopper.

The chopper reloading with water from another nearby lake.
