“I visited a friend’s house with a unique take on solar air heating. He coins his invention the Solar Coffin. This device heats air up to well over 100 degrees C within the “coffin” unit. The air is then moved under the slab of his house which stores the solar energy for release during the winter. This system is based on a system called annualized geo-solar developed in the US as a strategy to get off the heating grid.”
“Check out how I heat my house with my greenhouse! It’s so easy to do and it gives us (almost) free heat and many other benefits too. This could easily be an off grid way to heat a house.”
