I am by no means an expert, but it is my understanding that the reverse osmosis process requires many stages to achieve almost pure water and requires quite of bit of maintenance. Deans water purifier, that we saw last July at Deka, was not a Stifling unit, but was powered by a Stirling generator, but it could use any electrical source of power. It uses the "pressurized distillation" process that reduces the required energy to distill water by a factor of almost 50 and it is also my understanding that this distillation process produces absolutely pure water. It could use any water source including sea water and is maintenance free. Amazing stuff.
