The return of Tesla's solar (and other low heat input) design for home and commercial power systems using inexpensive technology discarded last century due to then cheap oil prices.

Ambient heat?

The article says this turbine can generate power from "ambient heat." I'm skeptical of that claim. Any sources to back that up? Novel compound 19:34, 19 June 2010 (PDT)

:I believe that the translation of this phrasing could mean that an active temperature gradient can be used to propel a turbine. Such gradients exist in places like deep water lakes upon which sunshine is available at the surface and on the land on the shore.

:I'm guessing the following scenario could be what could take place...

:Consider that the entire ammonia system is pressurized to a substantial amount so that the change from liquid to gas back to liquid is facilitated at an average temperature about half way between the warm temperature and the cool one.

:To facilitate the liquid to gas to liquid flow, atomizing heat exchangers would be employed. The sunshine strikes a passive solar panel having black coloring, the heat is transferred to the liquid ammonia that boils / atomizes easily causing it to expand propelling a turbine, the gas moves towards the cool lake water, where upon it liquifies again when pushed under pressure into a smaller transport tube. The ongoing gas pressure would push cooled ammonia up from the cool lake water into the surface level heat exchanger. The cycling of this action would continue as long as the temperature gradient was sufficiently large.

:Presumably, also, the system could be made reversible so that night time or winter time temperatures on the surface would cool the ammonia, and the moderated water temperature of the deep lake could heat the ammonia to levels where vaporization could be attempted?

I have said for many years now that the ammonia refrigeration cycle should be used as the air conditioning system of automobiles with the ICE exhaust heat as the energy source for the cycle.

Fully agree fran, not only that but what if you used the electrical energy you could havest to produce the hydroxy with the wasted heat???

Efficient Harvest of Low Heat Input

There is no uniqueness to the ammonia working fluid device over others [e.g. freon, propane]. Its only advantage is that it conveniently uses low

temerature heat sources. It is standard physics

otherwise. Ammonia, though toxic, has been

demonstrated to be adequately safe with the history of

aqueous ammonia refrigerators such as Servels that

have served for decades without a problem. Though the

Servels do not have turbines, turbines can be made

with hermetic seals by magnetic coupling through the

stainless steel piping typically used.
