Now this is cool...

If it in fact works, the Hawk-10 might be of significance:
"Take a piece of copper wiring," says Meddick. "It is encased in plastic – a kind of hydrocarbon material. We release all the hydrocarbons, which strips the casing off the wire." Not only does the process produce fuel in the form of oil and gas, it also makes it easier to extract the copper wire for recycling.

Similarly, running 9.1 kilograms of ground-up tyres through the Hawk-10 produces 4.54 litres of diesel oil, 1.42 cubic metres of combustible gas, 1 kg of steel and 3.40 kg of carbon black, Meddick says.

Watch a video of tyre powder being reduced by the Hawk-10.

It seems useful enough to be dollar-positive.

Anything that takes waste and produces something useful can be profitable.

But is it hydrocarbon-positive? Are the diesel fuel and gases enough to offset the coal and gas burned to make the power.

Another argument for nuclear power, perhaps. It makes items like these so much easier to get excited about. Because with a semi-clean power source, these kind of systems are very cool because they become positive in terms of dollars AND energy.
Of course, the rising prices of copper also make this sort of thing more economically viable.
