Don't believe everything you see – common sense meets heating miracle

A GAIA member has sent us a TikTok video. In it, someone builds a heater out of copper pipes, old refrigerator parts and a few fans. Powered by 12 volts. It looks impressive. A bit of tinkering, a few components that might otherwise have ended up in the bin – and supposedly you can heat your room cheaply. That makes you curious. And that is a good thing. After all, not every good invention comes from a large research laboratory. Sometimes it begins in a garage, at a workbench or at the kitchen table. But between a good idea and a working invention there is sometimes quite a long road.
