Wirelessly Charging Electrical Vehicles

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.

pretty cool but rather than installing them on higways i would place them in parkings, i think it would be more practical

[BeyondWorldsEnd]

the next step would be mario kart boost-stripes

супер

@rage02k Absolutely, it's unworkable. It would take more copper for the coils than remaining sources can provide. Efficiency would be a problem too.

[krasteller]

wouldn't the magnetic coils slow the car down which in turn would mean the car would need more energy to accelerate again??

[Chant88]

i dont like it

[rage02k]

This is so impractical. Even though if one implements it, expense to lay down such highways and maintain the coils would be really expensive. Its similar to having electric lines for trains only the tracks are missing. Rather have the car connected by an electric line below and between the two points of travel much cheaper.

These cars can charge themselves. Why chase something that would impede progress? Motion is a form of energy. Making the car move opens it to that energy and allows to tap and use that energy. Come on, this physics one Oh one. I would expect a little more from Stanford

Next, let's start building high voltage powerlines on rooftops; oh wait, Hollywood is not protesting so it must be a good idea.

thanks

Sounds ok

[NEWTUBE2012]

ok
