There's also lack of energy... do all the distillers come with free solar panels? Otherwise you need to have fuel.

- andygeers 19y agoThat's why the article refers to the Stirling engines as a potentially partner - you chuck your cow dung or whatever into the Stirling to generate the heat needed to distill the water
- LogicHoleFlaw 19y agoNot only that, you get electricity out of the engine as well. The waste heat from the electric generator is used to power the water purifier.
- jws 19y agoThe numbers in the article suggest the stirling engine needs 1kW of energy input. There is no need to use expensive photovoltaic panels. 1kW is about 1 square meter of mirrors in a solar concentrator on a sunny day at many latitudes. Solar concentrators and stirling engines pair nicely, though there may be issues at that small scale. Nothing more mirrors won't fix though.
