Green Lantern (Slate) sez: "Given how little we know about plasma gasification's environmental impact at this point, the Lantern advises caution. While the process certainly holds promise, beware of any company that touts it as a zero-emissions miracle that will quickly pay for itself. And no matter how many millions your town pours into plasma, it's not going to change the fact that we should focus first on reducing waste, rather than figuring out ways to perpetuate the more reckless aspects of our consumption."
