Heat source pumps, underground heating, wind generators & solar. They are all trying to do it right but they are all still so expensive compared to fossil fuel
On my pool Im going to use a heat source pump which uses compressed air. I am very much wondering about using the soloar panel idea to run the rest of the pool electrics.
Other than that, the size of these homemade solar panels on the roof would be huge to create enough for tumble dryers & overs.
