Wireless power could revolutionize highway transportation

By the time this is implemented widely enough to matter, electric cars will already have good range and quick recharge times. The hell is the point?
 
Does this team consist of 3rd graders? Because this technique is not new, nor innovative - and that diagram is terribly rudimentary.
 
meh I would go above ground instead. You know how trolley's and bumper cars are powered? With the electrical grid overhead connecting to the motor via the pole?

Why not use this method with stations every few miles. Where the driver can extend the recharging pole when his batteries need a charge. Use capacitor to battery system in car for quick energy dump so that each station need not be more than a few 10s of meters long.

I doubt (and hope) this will not happen. Having lost two (2) parents to cancer ... the fact they had a transformer (underground cables) and a cell phone had NOTHING to do with the brain cancer and multiple myeloma ... right?

Some advancements have too high a price ...

It didn't have anything to do with it, you are correct.
 
This should not be in the road, but in parking spaces at rest areas, etc. Your car could fast-charge as you are parked.

This type of wireless charging is actually very old and has been used for a while on many small appliances like toothbrushes.
 
Parking lots at very busy areas, yes, the highway, no.

You can't cost effectively dig up that much road. Academics has had their head up their own ass for a long time. If technology is supposed to be our energy savior we are pretty much doomed lol.

There aren't enough rare earth elements for everyone. IE Lithium, which isn't even good enough anyway.

You need to (re)watch the live action Mario Brothers movie. 😛

That's the point of fuel cell technology. The cell(s) convert a gas or chemical into realtime electricity without also creating excessive amounts of heat.

This technology is new and works very different than what you are thinking.

From what I read, it works basically the same way. Magnetic fields are used to transmit power over a short distance. Basically, you split a transformer in half. You put one half in the device, and one half in the base, or road. Bring them near each other, and power flows.

The "new" part here is using multiple "bases" strung along the road and intelligently co-ordinating the charging.
 
Repaving all of our highways will surely fix our energy problems. Nevermind that asphalt is an oil product, pay no mind at all.

No the new part is it uses resonate induction rather than direct.

I doubt resonate induction is new. Choosing which frequency to couple with can't be a new concept. I'm sure it's like radio, where, if people are going to begin to go down this path of transmitting signals through the air on some frequency carrier, they have to consider the possibility that a wide range of frequencies will be used in the future, and properly filter out unwanted frequency bands. But I think some posters are oversimplifying the problems I'm sure the stanford team is busy solving.

The first use of resonate induction was in 2006 to power a light bulb over a few feet. It is newer and more complex than you think.

Probably because it sucks. They got the grant money because it was a "green" energy project. To me it is really just a misallocation of capital.

No because it is new technology. You people are very misguided about thus technology.

It is commonly used.

Now what? Do we go to italics or bold to break the tie?

Wrong there are no consumer technology that uses this. Please do a little research before you speak

Show me 1 consumer product that uses this technology.
