I know this is “low-tech” but still think it might be possible to fabricate something even if it means spending some of your power budget maintaining the vacuum with a pump.
- jacknews 1y agomaybe vacuum insulated panels. A big thermos would be much more challenging, though there are already long vacuum bottles/tubes used as solar cookers.
- kragen 1y agoI have in fact cooked eggs at night by running water over them that was heated in such vacuum-insulated-tube collectors, then held in an insulated tank. This used to be an economical way to get hot water when PV was more expensive.
