Electric car batteries

[dextrous63]

I think something along the lines of hydrogen fuel is the way to go.

EVs with very long charging cables

No No it's the batteries that are the problem.

Just use mains electric motors - no batteries so no need to charge. Run some wires overhead and power the motors from those. To prevent mishaps with the pickups coming off the overhead wires it would be best to use some sort of tracks to keep the cars directly under the wires. No need to steer then either the car can just follow the tracks.

I think I might be onto something here. I'll ponder some more.

If we didn't have to steer,  perhaps we might as well all buy those driver-less cars then. 

BTW,  whatever is the point to them in the first place,  does anyone know?

Not too keen on the idea of overhead wires.  I think something more like turning roads into scalextric tracks.  These grooves would also help cyclists keep en route.

Me neither.   It would look really unsightly for a start,  and would so many wires give off any radiation?

Imagine the chaos in winter storms, if the cables came down, too.   :

And where would the money come from to wire hundreds of miles of motorways, I wonder?  
Perhaps cut us OAP's pensions a bit more?

Also, think of a the random training shoes hanging down from those cables.  Wouldn't be so bad if the wires could double up usefulness and act as washing lines.

You would have to hold the ladders while I pegged my smalls  (or not-so-smalls)  out though.

Peg 'em up with a wire to ground and they'd be dry in no time.

I was thinking that would be a good way then realised the problem - they would be a trip hazard. People would be tripping over the bodies of those who got electrocuted on the tracks and they might sue the council if they twisted their ankles or something.

Ah but,  what if they took off on a windy day, and stuck to someone's windscreen?  It could cause an accident. 

[klondike]

There are indeed lots of accidents due to drawers not being firmly attached.

Electric is not the way forward for road vehicles.  It isn't the problem of lack of chargers.  It isn't the problem of long charging times.
The real problem is lack of electricity.

If the ridiculously impossible 'nett zero' policy is to continue, and to add to that problem the insistence of heat pumps for domestic heating, the only solution would be to greatly increase the generation of electricity.
Windmills and solar panels cannot cope, especially in winter and no wind.

Nuclear power is the only real solution for reliable electricity generation, but we only have enough of that for about 25% of our needs.  Even so, there is a lot of opposition to that anyway, partly due to fear of radiation leakage and difficulty of disposal of used fuel rods.

Consequently, we have a choice of petrol or diesel, or the possibility of the future use of hydrogen or other fuels.

I agree, JBR.   But wouldn't you think they would know that before they started making them?   
Perhaps this winter's cold spell will make them realise this.

Toyota and Mazda working in partnership, claim to have developed a 'Hydrogen' drive that's lighter than the traditional internal combustion engine. It does about 35 miles on a gallon of water. Even more exciting is the V8 superstructure they are currently patenting. In series it drives Trucks, ships, and in time planes too hopefully. What an expensive malady the EV could turn out to be, a continent wrecker!

On its own this achievement, if it manifests to real production could right the Japanese Economy single handed.

Can you imagine Labour taxing water, I bet they'd cock that up too! Lets hope for his own sake 'Red Ed' can walk on water too, like his better known historical relative

I find that very interesting, and and apparently viable alternative to EVs and possibly traditional engines.
35 miles to a gallon of water sounds attractive, as water is virtually free at the moment, but to extract Hydrogen from water requires a great deal of energy, and presumably electricity.
Do you have any further information please?

What about in these increasingly hot summers, when we get a water shortage, and can't even use hosepipes?

Years ago,  people lived and worked in the area they were born in.  They either walked, or had a bicycle.
Now look at us.
