I supervise road construction and paving for a living. All they have to do to change my mind is put a hundred foot section into service in an interstate highway with twenty thousand ADT (average daily traffic) for a year in an area where snow plowing occurs regularly and record the KWHs produced, the repair costs and the friction numbers when wet or snow covered. Should be a piece of cake. SWMBO wants to know how far her forty foot school bus will slide across a glass highway covered with snow or rain water.

That's where Nikola Tesla tech comes in - beam it to the cars - or a bumper cars scenario with a metal strip in the lane aligned with a metal strip on the bottom of the car.

you're missing the point. Direct solar powered, no matter how the electricity is transferred from the road to the cars, is not going to be able to power any sort of highway traffic. especially at night.

Actually equally stupid. The cost to build a weight-bearing structure over a rail line would be prohibitive. It would have to withstand snow, winds (even strong gusts) and wide enough to allow for rail work and access to trains. Figure $100,000/100ft. That would be $5 million/mile, $1 billion 200 miles. Cost doesn't include the PV, controllers, electrification of rail line and engines.
Roofing over rail is not a bad idea. Though I think positioning panels next to the train tracks and at an angle would be a better idea.ian807 wrote:OK, the roadway idea is stupid. The idea of say, roofing over all railways with solar panels, less stupid.
