Pyroelectric Asphalt Roads   (+3)  [vote for, against]
Hot Roads that Generate Electricity

Before we decide to relay all the asphalt roads, or redo our infrastructure in the US, perhaps you should evaluate the potential for laying a pyroelectric layer so that when those roads heat up they generate electricity and thereby pay for themselves :]

I don't know what this has to do with anything...

Not the article I read, but the same thing. A little light on the science, no mention of any implementation. [Alterother, Aug 17 2011]

Strain and Spin Makes for Ultralow Energy Computing http://www.machines...ow-energy-computing
Traffic driving over strain gauges could also make computers as well, perhaps. [quantum_flux, Aug 19 2011]

Or possibly 'pyroelectric'. Or, perhaps, 'thermoelectric', which might even be relevant to the situation [q_f] describes.

HOT roads=PyroElectric! (oops, I didn't read [lurch]'s anno) but I found a pyroelectro link.

Either PopMech or PopSci floated a proposal a few years back about piezo-sidewalks at busy intersections to power the streetlights and traffic signals. The article said that one city in the US was giving serious thought to the idea; I think it was Philly. I'll link later if I find it.

Spelling Corrected, it's Pyroelectric, sorry

No need to apologize, he's dead.

In an airplane accident, so maybe he should have had a road take him home.

Before the name change I was looking forward to all of the street signs rendered in pieroglyphics.

Now it's just...
