Pyroelectric Asphalt Roads

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... http://www.pyroelectro.com/

Piezo Sidewalks http://artfuldodger...c-Energy-Harvesting
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...
useful.
