Theoretical Wave Action Pump, Making Fresh Water and Electricity
Intro: Theoretical Wave Action Pump, Making Fresh Water and Electricity
The theory: use wave action from the ocean to pump sea water uphill through a series of one way valves and reduced piping to a lipped dome reservoir, catching fresh water condensating inside the dome in the "lip", returning the sea water back to the ocean, thereby allowing hydro electric generation through gravity and water flow.
The question is this: will the wave action with the force of the ocean behind it be able to push sea water uphill to the reservoir?
If this can be accomplished the rest has all been done before.
If this can be done in area's of good wave action it may alleviate water and power shortages along much of the worlds coast-lines
Your comments would be appreciated

The waves may be a problem - pushing fluid up-hill, during low tide particularly.

Hi
The whole theory of this concept is based on large scale construction. The walls been between 50 and 100 m long, channeling the force and direction of the sea water to the pipe opening. There would be a one way valve opening inwards so the push of the ocean would hopefully have enough pressure behind it to force the water inside the pipe on-wards and upwards. Due to the one way valves low tide should not be a problem. As I said it is and idea and if it can be done, YIPPEE

i'm sort of convinced that with the whole ocean and wind pushing the wave to shore, that by channeling this force to a small area, one would be able to raise water through this method.
This would be and intresting project for those smart kids at university to try in a small scale wave pool to prove concept

A couple of beers and we are out to save the planet. The original idea was to produce fresh water on a constant basis to supply water to desert like coast lines, like the west coast of South Africa and Namibia. the fresh water would be used to plant pioneer plants buy digging away about 2 m of the surface sand, laying plastic sheeting, (rethought instead of plastic sheeting, a biodegradable material that could hold water and degrade over a period of time), recover the sheeting with the removed surface sand, water and plant.
r-philp - the scope of the idea is massive. the directional wall would be between 100 and 200m in length, the first stage one way valve, anything from 10 to 50 m square
Regarding the condensation aspect, the domed reservoir would heat up during the day (daytime temp between 30 and 40 degree's C, night time temp often below 0 degree's C) and as far as I am aware, as long as the dome cooled to less than the water temp, condensation would occur
Ironically, electricity production was an afterthought.
Rebellemming and Ranie-k: thanks for the comments, the concept although initially very costly was to have few moving parts and to be low maintenance
Your comments are greatly appreciated, lets work on this one and reclaim our desert like coastlines

1) wouldn't the constant influx of cool seawater inhibit the evaporation of the seawater, unless you restricted the incoming flow to a trickle?
2) if you did reduce the flow that much, it would seem that locating your generator on the return line might not be as efficient as placing it at the seawall, where the full force of the waves could act upon it.
Electrical generation aside, the idea of using wave action and tapering pipes to pump seawater to an evaporator is a great idea. It would be interesting to see how high water can be "pumped" with this method.
