asteroza + engineering + desalination   1

Interesting use of a linear piston motion of a wave power buoy to drive a mechanically driven high pressure seawater pump for a reverse osmosis water desalination rig. RO requires high pressure, which typically requires a lot of electric power for a electric pump, but by using gradual pressure building using a wave driven seawater pump, you can achieve equivalent pressures. Potentially convenient for small island resorts that have very little electrical power. But the long water pipe is a bit of a problem. If it were me, I would use the wave buoy to send pressurized seawaater directly via pipe to a beach building with the RO rig and a pressure accumulator tank, since that keeps the more finicky parts out of the water.
