Brexit, for once some facts.

placing the receiver coils inside the vehicle tyres would eliminate any air gap problems

Not an effective mechanism because the transmitter coil needs to be parallel with the receiver coil for efficient magnetic flux transfer.
I think the correct way forward is clean fuel. Purify the diesel before use and use urea to clean the exhaust gas.

Must take more tablets, I agree with Oldtom

Mike, tillson, old Tom.
You three are formally warned.
That's not the expected behaviour on this thread. You get a final warning in the event of reoccurrence, unless it's with Zatlan where agreement is an instant suspension offence.

I've posted him an agree this evening.

You have to hand it to Theresa May,she has managed to get a bill through Parliament that 70% don't agree with,including most of the opposition.
She has also managed to avoid the country in having a say in what she is doing. I think that more people are anti Brexit than pro Brexit,that may be wrong but we are not going to be given an opportunity to find out.
A minority of Tory right wingers have got their way and taking us in a direction that none of us can control,thank you Cameron.
Really is that democracy?
Whilst all this Brexit nonsense is occupying the news and taking up all of parliament time,the NHS and social care is being ignored.
When all of Brexit is finalised,whatever the outcome,our country will be a social and economic mess.
Theresa May bought off the Surrey referendum by saying that Surrey could keep 100% of the council tax,she is going to have to do that with every borough,where is she going to replace that money....it seems this government may be forced to become a tax and spend government,where did they get that model from,hehe? That is not going to please the Jams!
KudosDave

Politics being what it is these days (Nobody can predict the outcome, particularly political hacks), if Marine Le Pen wins in France, there may not be anything to Brexit from.

But much less bad than diesels, and when used in hybrids do greatly reduce airborn pollution in comparison with diesel, which is the big health problem.



Indeed, but as said not a health problem. They are just premature inventions, hopefully given time the battery solutions will evolve



The problem is inefficiency, the transfer rate suffers the airspace gap and current airgaps under vehicles are much too large. But of course the gap is necessary for road use.

Some bus designs have solved the problem by settling down at stops to give close contact between the road and bus transfer coils for burst charging. So far the most successful implementation of that form of current transfer has been in high-speed-flywheel driven buses in Switzerland. At stops the bus settles and the motorised flywheel is driven up to very high revs, the energy stored in the flywheel then drives the bus to the next stop. No battery necessary.
.

I think the problem is more effectively than inefficiency, the coupling between the coils at large separations is poor
A better system might be to use the scaletric cars principle a where conductive brushes connected with a slot and drew power and perfect tracking ... There could be an auxiliary battery for overtaking.....

Mrs May would lose her job if parliament does not approve her deal with the EU.

But at the cost of a very restricted contact area so inefficient. If moulded into the tyre rubber they could also be a major problem with lightning strike, albeit very rare.

Regardless of how often it's idea is promoted, current transfer coil to coil is relatively inefficient and demands a very small airgap and substantial area of transfer. The knowledge of this method is very old, but the problems are why the practical applications seen so far are just those I mentioned above.
.

Not with you on the lightning strike as they would surely act the same as a lightning conductor?
And the Faraday Cage protective effect of the car metal body shell would not lose integrity because of that.
improvements in the Technology have made Magnetic Resonance capable of quite large distance application
http://www.witricity.com/assets/highly-resonant-power-transfer-kesler-witricity-2013.pdf
Here is an extract
The MIT team demonstrated the highly resonant technique using a magnetic field to transfer energy over a mid-range distance of 2 meters, and an industry was born. In some instances, this technology is also referred to as “magnetic resonance”, and it is often contrasted to “induction” for its ability to efficiently transfer power over a range of distances and with positional and orientational offsets. Since that initial demonstration, the use of HR-WPT, or magnetic resonance, has enabled efficient wireless energy transfer in a wide range of applications that was not possible before. System Description Across an application space that spans power levels from less than a watt to multiple kilowatts,

OG, that method is still premature. It's true that higher frequency is more efficient, OK for toothbrushes and small appliances but there are quite a few obstacles to charging cars wirelessly. Your bike for example must not emit more than a couple of milliWatts in radio frequency. Charging a car effectively must supply it with just as much power as the car uses and more, that is around 3KW in RF power. There are also some required technical advances that are needed. We still looking for better ways to collimate strong magnetic fields if you don't want to microwave the passengers.

This system does not use transmitted RF it uses Magnet Resonance and According to the Blurb
"Applications range from very low power levels for wireless sensor and electronic devices needing less than 1 watt, to very high power levels for industrial systems and electric vehicles requiring in excess of 3 kilowatts."
Is already powerful enough to be useful

they try to blind the readers with science. MR and microwave ovens have much in common. Both are based on the same mechanism to transmit energy using electro-magnetism. You connect a transmitter to a receiver with a magnetic flux. Anything on its path may get fried.

Magnetron radiation is not the same as Magnetic Resonance, so the comparison of Microwave ovens is inappropriate.
Entirely different type of energy transference is taking place.

Bmw are working on such a system too

RM magnetic nuclear resonance or microwave or a shining torch, it doesn't matter much. The principle of transmission is the same for all of them, you convert the energy at the source to a beam that traverses space with little loss then convert the beam back to energy. The problem is our body interacts with the beam (either magnetic or electro-magnetic, magnetic flux is converted to electric inside our body) so the beam has to be confined or our body protected.
