The Microwave Magician

PopSci - Best of What's New 2007

I’m not sure if I’m watching a magic trick, or an invention that will make the cigar-chomping 64-year-old next to me the richest man on the planet. Everything that goes into Frank Pringle’s recycling machine — a piece of tire, a rock, a plastic cup — turns to oil and natural gas seconds later. “I’ve been told the oil companies might try to assassinate me,” Pringle says without sarcasm.

The machine is a microwave emitter that extracts the petroleum and gas hidden inside everyday objects — or at least anything made with hydrocarbons, which, it turns out, is most of what’s around you. Every hour, the first commercial version will turn 10 tons of auto waste — tires, plastic, vinyl — into enough natural gas to produce 17 million BTUs of energy (it will use 956,000 of those BTUs to keep itself running).

Pringle created the machine about 10 years ago after he drove by a massive tire fire and thought about the energy being released. He went home and threw bits of a tire in a microwave emitter he’d been working with for another project. It turned to what looked like ash, but a few hours later, he returned and found a black puddle on the floor of the unheated workshop. Somehow, he’d struck oil.
