Maybe this is old news but have you folks seen this?

From about 3 mins 30 seconds in. Is there any other information out there as to how effective this could be?
Guess it could be used in housing as well if built in from new.

That looks great. It works on the same principle as a rocket mass heater, charging some mass with excess heat that gets radiated back slowly. I could see this being used for home heating with an attached greenhouse. Let the sun heat up the air in a greenhouse and then pump that air through pipes embedded underneath the flooring of your house. The flooring would then radiate that heat slowly over a long period drastically reducing the need to heat the air in your house. Great idea!

Yes I thought of that as well. In fact the rocket mass heater thing is something that fascinates me at the moment and I've started another thread about an idea about that in the rocket mass heater forum (otherwise it will get confusing!).

Back to this sand climate battery - anyone else think its a good idea? Does anyone know any details? Is there a better way to prevent overheating in a greenhouse and usefully store the heat?

 
I am a man of mystery. Mostly because of this tiny ad:
