The problems is nothing is inexpensive to build at this point.
The second problem is that in many areas on the Puna side, it would not make a bit of hot water for 4 months out of the year, which I'm not sure is economical.
Still, these "sorts" of systems are proven. Just beware of designs from Phoenix or Sacramento and think you can plug it in here in Hawaii.
Be careful of hippie engineering. I would not want to introduce a bunch of plastic and hose and stuff into my potable water supply.
By the way I'm not trying to discourage anyone. Just understand the limitations.
