I don't think people think electricity is evil.

It is just charging an ev even for 200km is not a realistic mass ownership option with current infastructure .

.petrol is just to bloody convenient

I'm of the opinion that the so called clean electricity created by burning biomas is not as clean as might be suggested.

And 200Km (125miles) is (or should be) readily achievable by the majority of EV cars on the road today.

If I were to go EV then a range of 200 miles would cover (probably) 95% of my current needs. (pun unintended)

But, a 180 mile journey (to Bradford) might be a nightmare in winter with lights, heater, wipers and the possibility of A1 or M1 closures and diversions. When a 3 hour journey turns into a 4 or 5 hour misery run.

Currently I would start with a full tank of fuel and be safe for 400 miles.

I've just watched this video about upcoming battery developments.

I thought it was interesting but make your own minds up.

Aaaaaarggghhh My brain has got indigestion!!!! Too much information.....
I wonder who paid for that film - when something sounds too good to be true..... could be true, its amazing what 'they're' doing these days. All we need now is world peace.

Too too much information - what are they really saying?

Seems battery developments are ongoing, and in the future batteries will be cheaper and more power dense.

Yep, that does get filed under the no shit Sherlock category. The problem always seems to be getting from the lab prototype and patent application to a actual mass produced product. But I guess to be slightly cynical, only the first two parts are required to obtain funding. I suppose also, that there is no real point in putting a new battery into production if its 1% better than current with the knowledge that one that offers 1.5% better may be along in 6 months. And of course different applications have different versions of "better".

Yep, and we could sit around for years waiting for the promised technology to arrive on the market or, as I choose, we can invest in the best currently available and enjoy the pleasure it brings now.

Actually, while its likely, it is entirely possible they may be cheaper or more power dense, but maybe not both at once.

The iron air battery is has a better power density and doesn’t use exotic materials, just got to wait for the guys at Stamford to perfect the reversible part. EV battery research is useful as it will hopefully yield something we can use for energy storage cheaply, to peak lop the grid requirements. The thread amuses me, Phil finds some sh*te on the web. Electric conversions for escorts, ffs.

Yep, there is also loads of other metrics that matters for batteries depending on use. Charge rate, number of charges, discharge rate and so on. Not something I know much about, but there are folk that do and are working away at the problems.

I am not that upto speed with EV’s. I do work with a guy who used to design power trains for Rover in the 80’s and is into VW campervans. He investigated electrifying one of his flat screen vans when the engine blew up, but concluded that existing IC car transmissions aren’t really suitable to dropping an electric engine in due to torque issues. You get none of the benefits of regeneration either. Suggesting they are a gimmick.

The best zero emission proposal I have seen is using liquid air to power a turbine. Air can be compressed using excess power from solar or wind.

compressed air, who'd a thought it!!

I remember in the 60s we had small model aircraft that had reciprocating engines powered by sparklets bulbs. That was in the 60s but I regularly attend the vintage model aeroplane meets at Old Warden and these motors still exist and are still being built. I've never seen one scaled up though.

Not sure I follow what you are saying there. Are you saying regeneration is a gimmick which seems unlikely or just in the case of restomod type use wich if true is a bit ok, so what.

I have seen that suggested for energy storage for grid leveling, pumping air into underground spaces and then using the pressure to drive turbines when required. But never for vehicle use.
