Bod Posted December 6, 2018 Report Share Posted December 6, 2018 http://www.instove.org/node/130 Just seen this, 500w max power, would it be any use? Provides hot water as well as electricity. Bod Link to comment Share on other sites More sharing options...
Jess-- Posted December 6, 2018 Report Share Posted December 6, 2018 $8000 for a 500w system!!!!!!! far to high a cost for general use 1 Link to comment Share on other sites More sharing options...
stegra Posted December 6, 2018 Report Share Posted December 6, 2018 And that excludes the cost of the stove. Link to comment Share on other sites More sharing options...
Machpoint005 Posted December 6, 2018 Report Share Posted December 6, 2018 "It will use water-cooled thermoelectric technology to output both electricity and hot water" but how does it work? BTW, USD 8000 was always expensive but given the relative directions of travel of the US Dollar and the Pound Sterling it's getting more expensive all the time!

I'd be asking myself how the effect is scaled up, bearing in mind the vast amounts of energy put out by an Ecofan ( ).. Link to comment Share on other sites More sharing options...
