If you could recharge your electric car through induction coils in the road and charging coils at supermarkets and cars parks . There would be no need to spend hours recharging batteries ,would you buy one ?.

As long as we build more coal and oil fueled electricity generating power stations then this will work.
i would love to have an Electric Car. :Razz
I would rather like an electric car too. I'm not fussed if it can go faster - as long as it can keep up!
I find it shocking
only as clean as the source of supply
You are kinda right but actually it is a little more complicated than that.Quote:

Electric motors are more energy efficient, less heat is wasted and more energy is converted into movement.
Lighter, I don't think so.
a Nissan Leaf kerbweight is circa 1500kg
a nissan micra weighs in at a svelt 1100kg
Electric may be supplied to your sockets but it has to be transmitted to your sockets from the source of supply and the range of an electric vehicle is so poor you would need to calculate your journeys very carefully to avoid a flat battery when out and about.
I do think electric cars are the future and probably the present for city motorists, but we are some way off a useable electric option for rural motorists.
in the future we won't own cars anymore, we will tap on an app and an autonomous vehicle will pop around to take you to your destination.
We can pick and choose which models to compare but the premise still holds. Burning petrol in a car is a big waste of fuel in the conversion process where there are big heat losses. The potential for electric car development is huge as battery sizes decrease and energy storage capacity increases.Quote:

How do you envisage it going with freight? The huge lorries are surely the major polluters and there seems to be no solution for that although maybe, robots will just make absolutely everything we use on the spot in the future, thereby cutting the need for that form of transport. I don't know!
The only thing wrong with electric cars is they have electric motors, which like wind turbines use millions of tones of rare earths to manufacture magnets for the generators, the increase of electricity consumption will only increase this - perhaps not as green as you think. This is happening in China, Brazil, Africa - but I suppose as its not happening here its OK (NIMBY)
LYING hidden in an little-known corner of China is a town that will horrify you.
Baotou is the world’s biggest supplier of rare earth minerals — the fundamental ingredients used to make today’s technologies — and it’s hell on Earth.
This pastureland turned wasteland on the edge of the Gobi desert is a toxic nightmare, evidence of the horrific effect the pursuit of consumerism has had on Earth.

factor in the damage caused to the highways if the road weight of all vehicles increases by 30% then we will have increased potholes and resurfacing works required. All that hot burny tar won't be so good on the environment
I gather the US car firms will shortly be exporting coal-powered cars. Hopefully they can be adapted to burn multi fuels like wood and peat so its cheap and easy to fill up at the side of the road.... :)

yes the hydrogen fuel cell versions, a few hydrogen buses nipping about in AberdeenVirtually silent and no black smoke.Also quicker refueling than plug in vehicles, IMO thats the way the car should be heading.
Thank you. I did not know that.
And if powered by windmills, then one can hope they'll travel at least 50 miles before stopping for fifteen minutes and then heading on for a further ten?Quote:
