Check out this video, about the Williamson Ram Pump, a pump that concentrates the potential energy in a water stream to pump it to high pressures. No fuel needed, and very reliable. It seems it can be used for pressure dependent processes like reverse osmosis desalination.
Wave driven desalination is often done using direct wave energy, but this pump allows you to store the energy for use later, either to drive a turbine or desalinate. If the difference between eb and flood is small, this device can still amplify it to drive a serious turbine, provided the volume is 20 times larger than the pumped water. This device can even pump fresh water if the driving stream is polluted, they won’t mix.
"You can predict with 87 per cent accuracy the wave pattern for 30 days" (bron)
Wave energy is only allowed to develop slowly. Like tidal turbines suddenly environmentalists are all over these companies, like we seen with oil companies in Russia recently, it’s abuse of the law for commercial purposes. Wave energy potential is huge, enormous, can be 20 kW/m (meter wave front) and much more constant than wind meaning it could replace carbon base load.
"And there’s general agreement that you can produce energy for two to three cents per kilowatt hour without any subsidies."
The various wave energry concepts developed over the years are listed here (8 in total). The problem is the way these projects are set up, usually recieving serious investment after starting up, but then left to die firmly in the grip of the banks (whose main money maker is fossil cashflow).
Some of the companies below have since dissapeared. It would be interesting to ask the ones that are active what projects they have. We are working on a system that makes these sort of reports easy to make.
