Solar concentrator/trough style steam generator
I've got a steam heated brick house with a flat roof.I was planning on building some solar hot air boxes to supplement the heat in the winter. Then I started reading about parabolic /trough solar steam generators.Does anyone think its possible to to make enough steam on a sunny day with a big enough array to pipe it in to the steam system and actually fill the radiators?
