If you try this, be careful to make sure this won’t be near anywhere it might get knocked over. Reports are these are fairly unstable, and, naturally with using candles, there is a fire hazard.
We havent’ tried this, but it is supposed to produce enough heat from four lit tealight candles to head a room for about 15 cents or so a day.
Considering winter’s here, and for folks who are trying to keep electricity costs down, it’s worth investigating, or maybe it would make a cool science project for a student.
