My idea was to put piezoelectric ceramic plates under the road and when cars run over the plates it presses on the plates in-order to produce electricity.
... put the copper coils in the vehicles tires,, and with load stone inside the asphalt,, would produce eletro magetic generation.
RDyou said the road would act like a break because of eddy currents, we thought of that. That's why the magnets/coils would only be on down hill roads. the force of gravity is were the energy comes from, I hope I cleared up that problem
I would have been happy to see that the roads would produce just one kilowatt let alone 20 kilowatts for 1 kilometer of road. That's all energy that would have otherwise been wasted. The roads could generate just enough power for street lamps and stop lights (billboards and what not) In my mind your article is proof of concept. It would work.
The lamps used in streetlights vary in both size and consumption, but are typically between 35 and 400 watts,
The MIT News reports that two MIT graduate students in architecture have proposed to extract energy from the motion of humans through public spaces such as train stations:Quote A responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station's main lobby. The slippage of the blocks against one another as people walked would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current.But if there's enough motion to provide harvestable energy, there's enough motion for the humans to notice. Ever walked along a pedestrian suspension bridge that bounced under your feet? It takes more energy to walk on such a surface than it does on a rigid surface.Where does that energy come from? From you, of course. It's like carrying a parasite that takes a little bit of your energy. In fact, this approach is also called parasitic power generation. By keeping the parasite fed, you get a little more tired and you eat a little more food. In effect, you become a highly inefficient motor that runs on food.Food calories are inefficient to produce. A wheat field is a giant biochemical solar panel that turns a small part of the sun's energy into chemical compounds that you can eat.And then those compounds have to be kept cool and transported large distances, then cooked and eaten. By comparison, traditional electric power generation is hugely more efficient.So when you see celebrity Ed Begley Jr. using a stationary bicycle to turn a generator to power his toaster, remember that this is a crime against the environment--not environmentalism.The same goes for parasitic energy generation--it creates exceptionally expensive energy.
