Re: Marble Coals
It will really be the next step in the evolution of hookah smoking, when someone comes up with a good way of getting around the coals. Cigarette smoking by it's nature involves inhaling burning matter, and that can't be changed. But with hookah, all we want is vaporized glycerin with flavor, and perhaps some nicotine. That leaves tremendous room for the improvement of the apparatus.
Reaper: It sounds like a vaccum activated heat coil system would be the most effective alternative means of heating the tobacco. It might be too much trouble for someone to make such a contraption themselves, but once someone simplifies it into a marketable product, they'll probably make a lot of money off of it.
