Formula e on the bbc

Completely bloody useless round here

That would barely get me to work & back at this time of year. Looks like the future is hybrid so you have back up when the leccy goes away..

Their model has that ability from the small petrol engine and fuel tank but to me it defeats the object if you still have to fill it with petrol.

Until the batteries improve unless you are only doing the kiddie run in it there will be the fear of running out of juice. Electric vehicles are not going to make much real impact until the range is 200+ miles in proper driving conditions - eg a cold winters day when you need to defrost the windows & have the lights on

There was an interesting report on the BBC over xmas saying words to the effect that most hybrid cars are bought by companies for the tax breaks & the charging cables are left unwrapped in the boot as they are only ever run on the engine.

A client of mine visited the site I was working on over Christmas in a electric Mercedes without checking beforehand the electric grid had been connected. They spent about two hours pleading with the neighbour ( who had previously been the victim of supply theft for a cannabis farm ) on running an extension lead over the fence and across their garden so they could get a charge for the return journey.

Carrying a second motor around to charge up the battery will only make sense if it is exceedingly lightweight and runs off a renewable pollution free source , I'm unsure why manufacturers are not using a hydrogen cell for this purpose. Even so the continuous requirement to carry something around, for use in an emergency only does come with the loss of lowering of efficiency, plus the risk of it not functioning when needed.

There are safety concerns with the hydrogen cell in real life accident conditions which are genuine, I suspect and hope that this joint Australian Israeli solution will be the answer to such safety concerns
Cars could be powered by water with new Israeli technology

There is little need for new technology, since 20 years of improvements in safety around hydrogen have been in the main rectified, the only real developments remaining after the discovery of sodium aluminium sponges in the container is the seal improvement for long term storage. But this is not about powering the vehicle, but charging the battery of an electric cell, and so the total capacity required in the average car remains small (can be built larger to function at considerably lower than the Type 4 tanks with 10kpsi capability).

Welding uses compressed nitrogen and oxygen stored at around 2/2.5 kpsi per tank, the technology behind them isn't new, or from the realms of rocket science. When did you last see a delivery lorries using anything more than cages and chains, which is more about theft than collateral damage.

Sorry I do not agree with you on that point, there is always a need for new technology especially in this case because the introduction of long range ecologically friendly electric cars is still far over the horizon, therefore there is a need:- and an even greater impetous to develop is to reduce the reliance of the West on Arab oil because in case anyone has missed it, we are being played and manipulated when it comes to petrolium based supplies.

Aren't we also being played and manipulated with green energy based stuff?...
Most electric cars have like half of advertised range in real world, they certainly don't explain to people that batteries will only perform at their best at around 25ºC and when they are brand new, other than that battery capacity will drop severely. Of course high end evs will perform much better, but maybe you have to rob a bank first just to get one!

Of course we are. Those who told us years ago that diesel was the way to go have now had their information 'disproved' so now the environmentally sound option is to scrap millions of vehicles and build new ones (which won't last as long).

And, electric cars don't eliminate pollution; they just move it somewhere else.

And the idea of hydrogen seems to be popular at the moment, ostensibly producing water as bi-product, but where does the hydrogen come from? Don't think electrolysis of water is very efficient, so it's down to good old hydrocarbons (unless you know different), which needs a goodly amount of energy input.

No, there isn't . There never has been.
Localised legislation (plus some personal /preferential lobby groups) is behind innovation stifling that would have given the world a better fuel some fifty years ago.

It doesn't all come out of the ground.

I am disagreeing persay with your statement that we do not need to do R & D, we always need to strive to find better more efficient ways of doing things otherwise we may as well put just blow our brains out. R & D is what allows us to continue the exploration of the universe, or do you wish we were all back in caves rubing dry sticks together?

Of course R+D is necessary to improve things for the future, however a hydrogen cell generator for charging up car batteries can be more than satisfied using current technology.

I agree the concept exists but not for vehicular applications, everyone driving around with a 25Kg cylinder of hydrogen in their boot is obviously deemed by HSE as an accident waiting to happen otherwise this would already be on the road, whereas everyone driving around with a tank of water and a tank of an enzyme to produce hydrogen on demand as per my post #25 is obviously going to be a safer solution therefore worth developing further.

 

[Channel Hopper]

Ah, that was just an example of the devices out there. Nobody would require the size portrayed unless they were driving a fully loaded e-van in the inner Hebredies and got stuck in a ditch.
A 16kg canister (54-B - listed on page 8) would be adequate to get the vehicle mobile and back to a charging point, and/or the next hydrogen supply.

There are also hybrid /hybrid generator designs, hydrogen is not the only fuel that can be used in the event a supply becomes scarce.
