..and the metal chassis, shorting the loop out.

Indeed - in fact "metal anything"

 

[DetlefSchmitz]

It's not "my definition'. It's what I thought (perhaps wrongs) was being talked about Harry, yourself and perhaps the article to which bernard linked. In other words, I thought you were also talking about "how effective" inductive coupling was as a means of transferring energy from A to B (e.g. from a source to an EV).

No, basically you were strawmanning us, and that is not worthy of you.

I really don't understanding your problem.

As I've said, I was merely pointing out that what I thought (perhaps wrongly) people were talking about (i.e. how "effective" the inductive coupling was as a means of transferring energy at a useful rate from A to B) is NOT the same as "efficiency" (which is a word that was being used, by yourself and others). If my belief about 'what people were talking about was wrong, then I apologise for that, but my comment was obviously based on what I believed.

Ideally make them always green for EVs, because ideally that would enrage the anti-EV bigots so much that they would die of apoplexy and we would thus be spared their chuntering.

 

[ericmark]

I am not against EV's I have three, two e-bikes and a mobility scooter, but if the only way to get people to take up EV's is huge tax concessions, VIP parking bays, and turning traffic lights to green for them, clearly there is a massive problem with them.

 

[morqthana]

Tax concessions are not necessarily a bad idea in principle if the government wants to encourage particular behaviour - I wonder how many of the anti-EV fanatics are quite happy to take tax concessions on pensions, ISAs, etc? Or grants for insulation? But I agree that long-term subsidies for the EV market are not sustainable.

VIP parking bays? Don't know what you mean, but if it's reserving bays next to chargers for EVs, well, yes. But EV drivers taking the p--- by using them but not charging should get penalised. (DISCLAIMER - maybe they do).

As for lights - that was a joke.

 

[ericmark]

VIP parking bays?

The chargers often cause trip hazards, I know this can't really be avoided, but to place parking bays at the back of a car park, at least reduces the risk, however they seem to be placed closer to what ever the car park serves, pushing disabled and mother and child bays further away, and typically you get 6 EV bays to replace 8 non EV bays. Clearly EV's are wider than non EV's?

The way to promote EV's is not to alienate non EV users.

 

[EFLImpudence]

It's no different than Gordon Brown telling everyone to buy diesels.

 

[morqthana]

How on earth do they do that, unless people park in a not-EV-charging bay, and drag the cable over one of the footways?

typically you get 6 EV bays to replace 8 non EV bays. Clearly EV's are wider than non EV's?

My guess is that there needs to be an allowance for space on both sides of the car, not just the driver's, in case the charge port is on the nearside??

The way to promote EV's is not to alienate non EV users.

Frankly no. Gratuitous alienation should of course be avoided, but no accommodation with whinging snowflakes should be sought.

Parking spaces are too small anyway.

Parking spaces are too small anyway.

Or vehicles are too large?

I suspect that is driven by trying to keep the costs/losses of the feed cabling down.

Tonight, I went to collect an item I'd bought, from a large Victorian terrace of properties. The layout was really strange....

The front had bit of garden, the, other side of a public footpath, the terrace, a bit of a back yard, then a rough access road (adopted it seemed, then a variety of parking places, garages, then beyond those, more garden, where some had built conservatories, huts and etc..

Several of the occupiers, had run cables from the houses, across the road, to provide power to the garages etc., including a few cars being charged. Where cable crossed the road, they had just been laid on the road, but with those cable protectors. The road was damp, but heat from some of these cable had caused a dry stripe across the road surface.
