Hey gang!
Top of the morning to you all.
Anyone interested in sand batteries out there? I like the idea... Cheap materials etc
https://polarnightenergy.fi/sand-battery
Want to try and DIY a smaller, insulated prototype for a suburban/residential use (Heating mostly I guess to start with).
If anyone if keen to kick around ideas on materials and basic designs please jump in.
Also keen to hear why its maybe a dumb idea ;)
