This seems to be solving a problem that doesn't exist, or at least isn't nearly as important as energy storage.
We are OK with "plugging in" gasoline hoses, and I don't think anyone has a problem with plugging in an electric plug. It's the charge time and energy storage capacity that are the real issues.
- dogma1138 11y agoWell efficient wireless charging can also be used to power the car while on the road think of ev lanes that charge a capacitor bank in your car while you are driving so you don't have to drain the battery.
- akerro 11y agoDon't electric cars have solar panels in windows and on roofs? I've seen one like that.
- dogma1138 11y agoNo, not unless they are some competition ultra long endurance type projects. Even with 100% efficiency cars don't have enough surface area to come to even being close to be able to be driven on solar. Heck with a regular car the added weight most likely will make it less efficient.
- rz2k 11y agoFor fun here are some very rough figures. ~ 1000 watts per square meter from the sun ~ 5 horsepower from the surface of a car ~ 10-20hp for a car to travel at highway speed I imagine that 1 horsepower is much more realistic from solar panels on a car, even in perfect weather at noon.
- adrianN 11y agoThis will make building roads orders of magnitude more expensive. I don't think we'll ever have "power lanes".
- daurnimator 11y agoWhat about "power traffic lights"? slightly more plausible...
- mrexroad 11y agoParking spaces are probably as feasible as we'd get before energy model for vehicles changes. Parking spaces can be retrofitted versus having to rebuild transportation infrastructure. Plus, being a stationary discrete position simplifies the problem significantly.
- carlob 11y agoI think what you're describing are trains :)
- ethanbond 11y agoNo no, here in America we want cars that are cheap, safe, eco-friendly, fast, self-driving, and comfortable. Trains certainly won't do.
- the_mitsuhiko 11y agoIt does not solve anything for personal cars but it has some applications for public transit. In Vienna they started equipping new buses with pantographs so that they can charge from the overhead tram electrification when they are idle somewhere. Looks like this while charging: http://www.trolleymotion.eu/www/verwaltung/common/nimages/1368833221-Wien%20immaginePost-Ori-52.jpg http://www.trolleymotion.eu/www/verwaltung/common/nimages/13...
