Water pumping
Posted: Sun Aug 15, 2021 2:45 pm
Something Shirley mentioned in the viewtopic.php?f=21&t=4218 thread about moving the water from the flooded Nth Qld rivers to the Upper Darling, sparked my interest, so I Googled it and found this. It was called the New Bradfield Scheme ://www.abc.net.au/news/2019-11-01/bradfiel ... e/11662942 .
Expecting all of Australia to foot the bill for water reserved for Qld was never going to get support outside Qld, but could enough water be moved using renewable energy rather than building a mega dam and drilling holes through the mountain?
A few ideas:
An Archenemies Screw, lots of info on Google https://www.google.com/search?rlz=1C1CH ... 36&bih=723 A series of these water lifting devices powered by renewable energy and a series of dams to get the water high enough for a siphon system of pipework to get it over the hill.
A series of big ram pumps, explained here https://www.youtube.com/watch?v=zFdyqTGx32A that is a self fuelled pump that as been around for yrs. The ones I've help install had an air bleed in valve that just had a ball bearing is the sealing device, much like the snorkel and pin-pong ball that was used in the diving gear for kids ... well when I was a kid anyway
The top of the chamber used to store the generated kinetic energy from the water falling was shaped like an upside down bell, so they were nick-named bell pumps. The idea was the air pressure across such a large area could push the water up the pump line at a greater pressure and therefore higher than a straight tube could .....
A combination of such devices could move water but still return water to the river so it wasn't starved of flow completely ......
OK, lunch is over, anyone have any great ideas to add to the scheme .... or reasons why it just wouldn't work?
