They tested one vehicle on a 200 meter length of track!
Hardly a real life situation 

If you read the article, they installed it on a 1.6km length of public road (and 700m of public road in Israel). The 200m truck test is the first phase. They're seeking permission to do multi-vehicle tests with the full length.

The next test stretch is going to be between Milan and Brescia, in Northern Italy, on the A35 Autostrada.

It also says that it achieved a transfer rate of 70kW but is that 70kW to the vehicle or consumed by the track ?

Its going to need, probably thousands of times this amount to cope with all of the traffic - and that's just a short length of track

Why are you even interested, you're "sticking with IC to the end"?
PS the word "transfer" clearly  infers it's the rate to the vehicle.

Right and what's the efficiency going to be of such a sysem?
25% or even less?

That means that immense amounts of power will be required

I mean - something ini the order of 300KW per 30mph vehicle

So - for 1000 vehicles at 30MPH - 300MW or

 almost the full output of HinkleyA power station

Can you see what I am getting at here ?

Yes, I can see that you've got a problem with EVs and will try and pick at anything to discredit them.
Am I close?

Someone else with common sense !

I certainly do have a point - you work out the additional resources required and it is impossible to power the tracks needed !

I could say the same thing about people who are against IC engines !

But all the arguments against ICE engines are proven.
Most arguments against EVs are ill-informed barstool nonsense.

It would appear not, as even a cursory google gives articles stating the 'electric road' is 97% efficient.
TBH I probably didn't even need to google it to see that his guesstimate of 25% efficiency seemed ridiculous.
Using his 'common sense' analogy, it seemed unlikely people far cleverer than he or I would let such an inefficient system get to the stage it has.

The transfer of power from the track to the car is by inductive coupliing - which is almost 100% when two coils are fixed in close proximity / virtually touching (ie in a transformer) - but not in a moving application.  They've managed to get 60% efficiency on a bus at a 4.7 inch gap - The efficiency drops off at an inverse square rate over distance . OK My guess was slightly out - say 50% which still means vast amounts of power - from where ? Solar - so we can only drive during daylight ?

Wind - so we can only drive during storms ?

The national grid is struggling as it is - without the extra demands of 30 million cars and trucks

Capacitive coupling cannot cope with the power demands of a vehicle !

And then there's the scalextric controller - who gets to use it ?
