And what was the point of heating wet sand? Serious question.

@jsd21hb Hi there! In this first simple/small scale test I just wanted to see how easy/efficient different heating methods were. I have made a new, bigger scale 24h test which I will upload here tonight. kzitem.info/news/bejne/0K6K2KyJfp6eg3osi=QGbb8kggciukRri3 The final version, which will heat our house during the winter, is ment to be over 45 ft long, and over 7 ft in diameter, and will be insulated with enormous amounts of rockwool insulation! :)

How long did it take for these to cool? I'd love to hook something like this to the input/output of a water heater/freezer respectively via heat pump. I haven't seen any data on the concept. I've seen reviews of heat pump water heaters and folks say it makes their garage/cellar cold. Phase Change Materials could also be super fun. Seen nighthawk's videos on 'em?

Okay! Check out my second sand battery concept video, you will need a LOT of insulation since the sand temperature can get many several hundred degrees Celcius/Fahrenheit. The DeltaT gets enormous... In my final test, I will use longer pipes, more sand mass, and a LOT of insulation. :) m.kzitem.info/news/bejne/0K6K2KyJfp6eg3o
