electric cars with no battery - power from the road
 

Its now possible to have an electric car with no battery and get the power under the road.

this would make the cars very cheap and much lighter.

Am I the first today to point out what a fucking idiot you are?

That's fucking brilliant really. We'll never have to pay for gas, and never have to plug our cars in. They'll just run.

Well it might be if the news wasn't about 2 years old.

What would be interesting is if electric cars could run without a battery and get it's power straight from the road. Instead, the video is about inductive charging.

I will watch pretty much anything Robert Llewellyn does.

An ex of mine has an electrical car ..the Leaf. It was good stuff but the charging situation was the only issue. Since I live in a city, I could see it as a viable choice if there were more charging stations around but so far there aren't enough.

:2 cents:

Tesla would make "free energy" cars, but he is born in bad time :)

watch it near the end.

they say they could put them in a line under a road and the car would get all the power as it drives down the road.

the sugestion is just to have a small battery for when the car is not on the grid.

this will be the question.

will it be that they install the points once people start to buy the cars a lot.

or...

will it be they install lots of points to encurage people to buy the cars.

i remember in the uk when cars went from leaded to lead free. at first finding lead free petrel was almost imposible. today its at every station.

the advantage to firms is that if you have it in your supermarket car park (a charging point) it means you have people who will be hanging around to charge there cars, so it should result in sales.

Oops!

Inefficient as Hell, requires terrifically huge amounts of electricity, most of which is wasted in the inductive transfer and would require complete reconstruction of every road equipped for this kind of electric car.

" Electrified roads could power cars from the ground up

13 September 2011 by Wendy Zukerman

The cars of the future could be powered by electrified roadways. Such technology would allow electric cars to forgo their heavy batteries, which not only add to a vehicle's weight, increasing the energy needed to move it, but also force it to sit idle while recharging.

The idea has been around for decades. Previous attempts used an electrified coil in the road to create an electromagnetic field that interacts with a coil attached to the car. "Since the coils must be exactly aligned face-to-face to achieve a high energy efficiency, such schemes may be useful for [charging] vehicles in a parking lot, but never very effective for cars while running," says Masahiro Hanazawa at Toyota Central R&D Labs in Nagakute, Aichi, Japan.

Hanazawa and Takashi Ohira at Toyohashi University of Technology, also in Aichi, are developing a system that transmits electric power through steel belts placed inside two tyres and a metal plate in the road. "Our approach exploits a pair of tyres, which are always touching a road surface," says Hanazawa.

To test how much energy would be lost as electricity travelled through the tyres' rubber, Hanazawa and Ohira set up a lab experiment in which they put metal plates on the floor and inside a tyre. "Less than 20 per cent of the transmitted power is dissipated in the circuit," says Ohira. The team presented its work in May at the International Microwave Workshop Series on Innovative Wireless Power Transmission in Kyoto, Japan.

With enough power the system could run typical passenger cars, says Ohira, and the team are now developing a small-scale prototype to prove it. He admits, however, that the system's energy loss is "much higher than regular batteries".

John Boys, an electrical engineer at the University of Auckland, New Zealand, notes that with this system, the metal pads on the road would need as much as 50,000 volts to power the car, the same voltage used to operate tasers. "You wouldn't want to step on that," he says.

What's more, at the energy levels needed, the electric plates would produce a large magnetic field that would "cause significant radio-frequency interference that might create chaos with all manner of electrical systems", says Boys.

It would be expensive to "rip up the roads and install the necessary infrastructure", says Daniel Friedman at the University of New South Wales in Sydney, Australia. But he adds that one way around that may be to limit metal plates to main highways, and then run cars on other roads using small batteries."

trolleybus. hardly a new idea.

Damn cool, let's see what will come of it!

goddamnit, could you stop your inane dribble please? You moron

News:

They are going to do it in the UK.

I wonder what the EMF effects will be on humans and animals if this is rolled out en masse.

This is from 2012. I read the other day that in England they are testing roads charging cars while they are driving on the freeway.

Amazing what technology is coming to, glad I live in this generation.

It's a fun filled buzz, couldn't ever go without it ;).

From what I gather none.

No more than any magnet.

^^ this

They could use proven technology today to make intracity commuter car lanes where there would be stops where you could disengage the "trolley rail" and continue under the stored electric power that you charged from the rail as you commuted.

Intercity and interstate would be too costly to construct but more than 50%? of travel is on intracity high speed highways. This would also create good jobs in electrical engineering and construction as well as new good pay road construction jobs.

The vested interests in the internal combustion fuels industry (Big Oil) would be the only opponent. The ''trolley rail'' lanes could be self supporting via a usage fee or monthly permit.

interesting

Same here. I think its a really exciting time, science and technology wise.

On the subject of wireless charging: You can buy a wireless charger for your garage. I decided not to because its beyond my budget, and since there's some energy loss, it takes longer to charge the car.

However wireless charging on roads seems like a great idea. Maybe in a few years the price might come down enough to make it really worth while.

The idea makes total sense though. Can't wait to start seeing it in action.

which is it, a battery or no battery?



no matter your dribble, it's possible to have power with a battery

The battery would be required. You would of course need it to travel on roads where in-road charging was not available, and it would also act as a kind of a "buffer" between the electricity from the road and the motor itself. Otherwise your car would probably be subject to variations in energy such as spikes and drops.

Used "today", If current electric cars had the receiving coil in them now and there were highway lanes that were producing inductive charging, it would extend the range of cars like Tesla's and Chevy Volt's to thousands of miles per charge.

So it works on the street??? Intresting?? What happens During a power outage?? The gas cars can still go....
