Im going to need to get water into the bit that will eventually be used as an allotment/garden . The burn is adjacent but down a few feet , so i need to raise the water. And I thought an Archimedes screw might be the answer . So its time for some experimentation.
The necessary bits:
- a long hollow tube ( plastic for its lightness) . this is 6" diameter ducting
- some tubing to transport the water . 1 1/2 " plastic pipe
- Ducktape (you cant make anything without ducktape)
And then taped the tube to the outside of the ducting and took it to the pond
and rotated the top ( replacing it in the notch in the bench each time .
And water was lifted out of the pond and deposited in a bucket !
So the principle is good.
The outstanding problems are :
getting the thing centred on an axle. Ive got length of 2"x 2" timber but it will be too heavy.
fixing it in the burn. Some sort of cone arrangement fixed to the bank ,that the ducting pipe sits on so that the water pipe dips into the flow and the ducting pipe to rotate?
Getting it powered. Something wind powered is the obvious source of energy. Attached to the top? Gearing ? Fail-safe so it stops in 70mph winds ?
This pipe is too heavy , so the next thing to try is a length of downpipe.
