that's the old thread, a lot of our opinions are already in there. as for me i think it's a complete waste. an air compressor and a coal burner will do the same thing.
but i'm not huge on aesthetics when it comes to inventions like this. coal burners and compressors lying around may not look great but to me they do the job just fine and have been for a while so i'll stick with that.
i'd still love to see someone get this and do a review
