BURN ME UP, SCOTTY
Super-Hot Trash Zapper May Yield Hydrogen

This just in: The future is now. "Plasma torch technology" is=20
gaining acceptance among corporations and governments, and may soon=20
show up at a waste facility near you. Here's how it works: Trash --=20
anything from municipal garbage to toxic waste to PCBs -- is zapped=20
(at least we think that's the technical term) with a plasma torch=20
that burns three times hotter than the sun. The resulting products=20
are obsidian-like stone, heavy metals that can be recovered for=20
industrial use, and hydrogen-rich gases that can serve as fuel. One=20
company has already developed a filter that will extract pure=20
hydrogen from the gas, which means plasma torch technology (we love=20
saying that) may one day play a role in the much-ballyhooed,=20
possibly-just-around-the-corner "hydrogen economy." The consensus=20
among scientists, enviros, and sci-fi devotees is that the new=20
technology is "rad."
