with what you've explained so far. It needs water but dry air, which sounds like desert conditions with water as a fuel source. Does anyone see a problem with this scenario?
How water is expected to be lost in evaporation? If it's a lot, then it sounds like it be competing with an expensive commodity in an area where it's most valuable. I suppose it doesn't have to be potable and could use rainwater even. So basically, we don't know if it's economically viable because a prototype hasn't been built yet.
In any case, the permanent magnet motor looks VERY promising and from what I hear, it's already being used in those 50+ mpg Japanese cars. The US better get with it or it's going to be left on the ash heap of free energy history...
