Electric vehicles

recall reading somewhere though that to get the same donkeys out of a lump on H2 in comparison to oil based fuels, requires virtually doubling the engine's size -- or put another way - you only get half the power from hydrogen as a fuel, in comparison

I think I might have said that a couple of years back. The problem is actually on-machine storage - you can’t easily carry the same amount of energy in hydrogen as you can diesel, at this time anyway, but things are moving. So basically you can produce the power, but not for so long until storage improves.

but things are moving.

Tbf the answer to all our problems might be just around the corner but completely unimaginable at the same time.
Nuclear fusion could be cracked or battery technology could take a massive leap.

JCB's business plan doesn't seem to actually be based on getting the hydrogen engine to be the best it can - more about selling / renting companies solutions for creating and delivering the hydrogen on sites.

There’s not a lot of point optimising the engine until there’s a reliable source of hydrogen. Look at early diesels.

or electric.. noone wants all these electric vans… I bet if you offered them 5k they’d take it!!

Caught tail end of news earlier government just opened a consultation with manufacturers to see how they can achieve 2030. You can bet your arse they will throw money there way to try and achieve it

might as well just burn the £5k in the wood burner, for what it'll be worth in a very short space of time .... can't see many scrappies taking it either

only way it'll happen is the gov. buys all the vehicles they're all starting to cease production of .... or sell them at giveaway/too good to resist prices to punters to throw away as issues arise with them.
a major issue I see these days is so few ppl actually OWN their vehicles, so binning them off isn't an option, when the payments still need to be made and can't see many finance houses wanting to repo. the piles of crap

It's what they want, everyone leasing remember "you'll own nothing and be happy"

that is the thing i worry about ,the amount of money being poured into battery research is humongous.and yet nothing much to write home about in the big jump in battery run time length ,

 

[pettsy]

Vw transporters worth good money on second hand market, the electric versions used however are available for peanuts!

If you want a laugh look up 5 year old teslas

I've seen reports of some very efficient high energy density batteries. Just can't be recharged or recycled.
Also the big tech like drip feeding advancements and string things out to maximize profit

i agree with the above ,but the big jump will make zillions ,so i think companys would like to be the first with say a 650 mile battery that charges in15 mins

trouble is you can't get more out than you put in and 'filling it up' at that rate would need some sort of infeed
unlike a, say, liquid fuel, where the energy stored is condensed and converted for use ... what you get back is the same as what you put in, less losses.
can't condense leccy's energy for transfer

Depending on where battery technology goes there will be options. If they can increase the storage density with cheap and easily available materials then battery exchange is
an option. Whilst they can't condense electric they might find the technology to charge them at 10x the power output of current chargers. Big cables but if the tech is there then a universal port might be available that you drive the car onto to so no need for cables.
Might even end up with sections of road that charge. The possibilities are endless.

Just thinking about battery's in reality.
Dad had one of the first Bosch cordless drills ....with chuck 30 odd years ago.
Took hour or two to charge and lasted a Good shift.
Have they actually improved that much when you step back?t
if that rate of improvement carries on leccy cars will take a while to get much better
Or are we being conditioned to just drive and stay local ...

Easy.
Did you ever watch Get Smart - same, but without the shoe.

I shall give one or 2 a go at some point …. Couple of my employees could easily have off road charging and don’t do big miles and don’t tow.
New prices still mental though
