London Gets First Electrified Roads That Charge Cars Wirelessly

lmao.

awesome clip! i almost died laughing at that episode the first time i ever got high lol.

That would be akward :(

Of course not.

True Story...
I had a neighbor who had new rims on his truck and a dog kept pissing on them. He took a 330 Volt capacitor and charged it with a spark plug while the engine was running......... Now we are talking at least 5 Thousand Volts DC.... He ran a wire to the back of the rims and connected it.... He was thinking he was going to get that damn dog but good...
Later that night we were all drinking beer and joking around in his garage. He decides to take a piss next to his truck in the driveway.....drunk as a skunk he forgot the wiring job he did......He remembered pretty quickly....my face hurt for a week from laughing so hard.
That had to hurt but it was over in a flash...punn intended.☺

That was a great clip.!

lmao. epic.

ROFL

I read somewhere that comedy is funny because it's true.

Which would probably explain the number of votes on this post =)

And what will provide all of that power? What power source will be used and what about voltage drop? For example a 20 amp conductor #12 will carry 120 volts for up to 350 feet more or less depending on covering of the conductor. After that the voltage drops to 90 volts. The longer the lenght of the wire the more impedence and the more voltage drop.
Just wondering what super conductor could be used at normal temperatures with no voltage drop. Cars would speed up and slow down, speed up and slow down, depending on the amount of traffic, make sense?

They are removing the spammer profiles as fast as they can - there is obviously either a huge team of spammers or a bot doing the spamming. I keep flagging the profiles of new spammers, and they are then quickly removed.

I am sure not right away, they will probably want to see how it works within the city first fix any kinks so your car doesn't screw up 20 miles from town. If it does screw up in the city at least you might be able to park or pull over if not HELLO rush hour traffic! I am sure though you can drive from one city to another you would just need to have enough power or have to stop at a charging station. It seems more about the roads being able to charge the car while its running or parked then the cars running strictly from the power from the road themselves.

it's the charging system that is being integrated into the roads, not a car that is designed specifically for them. if the charging pads were embedded in the roadways in between cities, you could feasibly drive for 100's of miles in a car that would normally only be able to travel

In general, all-electric cars are designed for urban use, which contributes to lowering the pollution in cities. For long haul and driving in the country, hybrids are better suited.

It would be interesting to see the first cars, with antennas' sticking up in the air to run on the power line. They could call it a Trolley Car. yuk , yuk,....

Hahah that would be cool i don't care if they are the ugliest things in the world, as long as it is helping our environment that is what really counts.

Actually, they can get around a bus that is stuck - they have batteries with a certain amount of autonomy.

No hazard. No wires, nothing to touch. Same principal as the way an electric tooth brush is charged. Coils encased in plastic are placed near coils also encased in plastic, and through induction, current is passed between them. Not as efficient as direct contact, but safe.

No, it doesn't, there's no danger whatsoever. I have an induction cooker - I can put my hand on the plate-areas that are switched on, an I don't get an electric shock, neither is there any heat. I need special pots and pans with a thick steel base. The induction will heat the pan and the pan will cook the food.

My induction cooker is far more efficient than any other cooker, whether electric or gas, and uses far less energy than other cookers to boot.

You're comparing apples to oranges. If you compared the efficiency of your induction cooker to the same with a direct connection, the induction would have about 80% efficiency of the directly connected.

I've had gas cookers and electric cookers. Not only are my energy bills significantly lower with my induction cooker than they were with my previous cookers (gas and electric), water boils and food heats up and cooks several times faster with the induction cooker than with the electric or gas cookers, and I have absolute heat control with the induction cooker - even better and more immediate than with a gas cooker. So, my induction cooker has over 100% better efficiency than the normal electric and gas cookers.

Still apples and oranges. Compare induction to non-induction (direct connection).

My induction cooker is directly connected to the electric current. What kind of cooker are you referring to as "direct connection"? As I stated above, induction cookers are more efficient and less energy-hungry than gas or electric cookers, which is why they are so popular.

"Induction cookers are faster and more energy-efficient than traditional electric hobs; moreover, they allow instant control of cooking energy, which no energy source other than gas offers."

"According to the U.S. Department of Energy the efficiency of energy transfer for an induction hob is 90%, versus 71% for a smooth-top non-induction electrical unit, for an approximate 20% saving in energy for the same amount of heat transfer."

Ah, I see where the confusion is. You're speaking of the efficiency of transferring heat from a stove top to a pot, whereas in this case (electric cars/roads) we're talking about the transfer of electricity from the road to the car via an induction coil. It would be more efficient to plug an electric car in directly, as opposed to using the induction coil. Obviously, plugging in is not feasible for a moving vehicle. See this article on resonant energy transfer: http://en.wikipedia.org/wiki/Resonant_energy_transfer
Specifically, "the efficiency is somewhat lower (around 80% at short range) whereas tightly coupled conventional transformers may achieve greater efficiency (around 90-95%) and for this reason it cannot be used where high energy transfer is required at greater distances." The distance between the car's coil and the road's coil would not be very close, so I'd say the 80% number is more accurate.

I cannot but concur! :)

On the other hand, the confusion was not mine, since I was responding to your words: "You're comparing apples to oranges. If you compared the efficiency of your induction cooker to the same with a direct connection, the induction would have about 80% efficiency of the directly connected."

I wish for quick implementation of this technology around the world! (hey, a guy can dream...)

Oh, man! Forgive me for not just dropping this, but I'm a science kind of guy, and can't resist. I still stand by my statement regarding apples and oranges - especially because the type of induction you were referring to has little to do with that referred to in this article.

Induction is induction, the principle is the same.

Check out my profile, where I say what I would change about the world, my friend...

Nice, I cannot disagree :)

On the other hand, it all depends on which education and who is giving it. Taliban means student(s), they were intensely and lengthily educated in Madrassas run by extremists, for example.

Ouch. I think we can agree that isn't education. It's brain washing.
