The Finnish system is just heat->heat. They generate heat when the wind is blowing, and inject heat back into the district system when it isn't. Super simple - resistive heating, and passive heat transfer.
This system produces electricity. Exciting, but much fancier.
- dubcanada 3y agoA stirling engine can generate heat from electricity, such as those used in MicroCHP, you can burn wood, produce heat, and generate electricity from that heat. You could do the same with a pile of sand. You just need to pipe liquid through the sand, and a supply of cooler water.
