Yeah, that's it. Taking free crayons from Crayola, turning it into fuel, and selling it to NYSE: X (US Steel) is real boring stuff that the market wouldn't be interested in. Would be a real yawner not worthy of PR.
Good call.
lol
PS -- nothing novel my butt. The American Society of Mechanical Engineers has a different perspective than a "we need more information" still patent pending from the USPTO.
