Design News - Captain Hybrid - Wireless Power Pitched as Replacement for EV Batteries Yes, we probably do need that battery pack. There's no estimate of cost whatsoever in the article. The infrastructure would be huge. Can you imagine how much copper this would require?
Yeah, this would take more than it would to implement charging stations, and until all roads are covered, aren't you screwed on a road with no coils without a battery to store the energy you previously received? Could be a good complementary tech, but not a replacement -- not now anyway.
Well, if you had a 60 km range battery, and all major roads had this technology, then it would all work. That's a pretty big if, though.
Lots of fun in the lab, impossible to implement in the real world. They can't maintain the roads properly as it is, and bullet trains should be built first to reduce air travel. By that time, batteries will have improved a lot...
also how are they going to handle billing how do they tell how much power I'm using and how many cars/trucks can use it at the same time (sektion/power)
If the government took the money that they subsidize oil this could be paid for, at least the infrastructure. Use could easily be determined by miles, or sensors in the road. While I dont agree that it will replace batteries, it will allow you to have a smaller battery as your battery use will be limited to "off grid" driving.
This idea goes all the way back to Nicola Tesla. Too much infrastructure and who wants that much EMP going through their body anyway.
