is it a definite no?
Believe me, there are few areas of technology that have been raked over as thoroughly as this one.
Articles imply a lot of things. Some journalists will believe absolutely anything.
And who knows what this MIT prof is doing, taking calls from guys like this? Maybe he hopes to gently steer the poor guy into the therapy that he clearly needs. Maybe he likes seeing his own name in print. Or maybe he's a crackpot, too. The fact that he's an MIT professor is hardly very reassuring. I've met some very eccentric Ivy League profs...
That or our nation's physics education is not so hot.
Or, much more likely, we'd heat the Earth up enough that we could successfully radiate the excess energy out into space. Al Gore would not like that plan one bit.
Of course, while you're violating the second law of thermodynamics, I suppose you could always build a second machine that takes the exhaust heat from your perpetual-motion-powered cars and planes and sends it back to wherever it came from.
Energy just comes up out of the ground, as trees or coal or oil or uranium, and we use it, and when we need more we just do more digging or chopping!
Geologic time is an alien concept for humans, far more alien than anything ever shown on Star Trek. Even those of us with lots of science education have trouble grasping it. It's really quite hard to look at an oil field and think of it as the accumulation of millions of years' worth of solar energy. It's like trying to remember that you are one of seven billion people in the world: that number is so much larger than the number of your friends that you can't really understand it.
