Businesses that have a few extra parking spaces and about $850,000 extra in their budget can invest in the GEM (Green Energy Machine) to crunch up trash. The generator accepts food, cardboard, plastic and organic waste, shreds it and turns it into pellets. These are then fed into a gasifier which produces synthetic gas that burns in a natural-gas microturbine. GEM will not accept metal and class because they have no energy content and can convert up to three tons of waste. Here’s hoping some enterprising person/company will create a GEM for the rest of us at lesser prices.
