IST Energy GEM

The trailer-sized Green Energy Machine (GEM) is the first all-in-one, on-site device to produce clean energy from trash, letting business parks, universities and towns make their own power. IST shrank the components of big gasification plants found in several American cities. Companies toss trash in, and the machine compresses and blasts it with 1,600°F heat, turning it into a mix of combustible gases. The gas can then be funneled to a nearby generator. Three tons of waste a day can heat and power a 200,000-square-foot building, as well as the GEM itself.
