I could be completely wrong, but my understanding of Stirling engines is that they are external combustion engines, as opposed to our common internal combustion (gasoline/diesel) engines.

I was under the impression that the heat from the external source (fuel) was used to heat the water, which ran a steam powered turbine, or some variation of that.

The clean water is a byproduct of the engine, in that it was vaporized and then recondensed. There still is a need for a membrane free filtering system so that the contaminants do not re-enter the reconstituted water.

The electricity is the product of the engine, in that a generator is what is spun by the engine. (as opposed to an irrigation pump, or some other mechanical tool)

I also thought he had considered adding a cell phone receiver/transmitter to the package, so that this one machine can modernize the tiny village by bringing electricity, clean water, and communication with the outside world all in one package.
