it's called geothermal energy, but the stupid hippies won't let us build a geothermal plant on the super-volcano under yellowstone.

as for dust, i'm pretty sure it's the remnant equivalent of crystalised mana in things like magic the gathering, in MtG, mana is the life force of the planet, raw energy produced by the plane and attuned to one of 5 elents(or rather colors) based on the location it is drawn from. mana cna be crystalised and congealed in a number of forms, such as in the ravnica cycle books whee blue mana is used to make blue tear-drop shaped healing items. of course, those healing crystals can have severely detrimental long term effects if overused, namely mana poisoning. perhaps dust can have a similar effect if overused?
