He’d done it.  Just like Dr. Frankenstein, he’d brought the beast to life:  his Thermo-Depolymerization Unit, or TDU, lived – years in the making, like nothing the world had ever seen, and until five minutes ago, only a theory.  Marty had envisioned that the TDU would take garbage, computers, old sneakers, last night’s dinner, yard waste, old fence posts, plastic tupperware, with or without lids, old sweatshirts, used ball point pens, broken picture frames, old love letters, paint waste, empty cardboard boxes, broken refrigerators, busted telephone poles, wrecked car parts, or the whole car for that matter, old comic books, unwanted furniture, hell, this machine could take anything carbon-based, and do something magical with it, something that, to date, no one else had figured out how to do – take trash, and convert it into oil –  pure, unadulterated, car-starting, engine-revving, turbo-driving, eighteen-wheeler-moving oil.  Marty figured that the TDU would mimic what Mother Nature did every day hundreds of miles below the earth’s surface:  break down fossils into fuels.  But Marty’s contraption would take about three hours instead of millions of years, combusting nothing, and leaving no waste.  After twenty years of toil, Marty’d had his share of false starts.  But now the whir and hum of booster pumps and coolant fan units was evidence:  modern-day alchemy.  Marty had called down the vision.
