Well, if it works, it works. Archive: https://archive.today/COsoH From the post: >>[Zen Garden Oasis] wanted to heat and light a space using a candle. But candles aren’t always convenient since they burn down and, eventually, you must replace them. So he built copper candles using a common copper pipe and an old glass jar. Of course, the candle still takes fuel that you have to replace, but the candle itself doesn’t burn down. The basic idea is that the copper tube holds a high-temperature carbon wick that stays saturated with fuel. The fuel burns, but the wick material doesn’t. The copper part is actually concentric with a 3/4-inch pipe mostly enclosing a 1/2-inch pipe. The inner pipe extends further, and there are several holes in each pipe for fuel and air flow. The extended part of the pipe will be the candle’s flame. The wick wraps the entire inner pipe, stopping when it emerges from the outer pipe.
