Has JCB saved engines?

Wait, what, not 50%??
I'm shocked, shocked i tell you.....
This is a problem we see a lot of, that because electrification is so new to most people, they simply don't have an instinctive handle on what is, and what isn't b*llsh*t.
If i said
"My golf 2.0 diesel will do 300 miles per hour"
Pretty much every single person on this forum would know i'm talking crap, because they have had years to "calibrate" themselves as to the likely sensible range of values for various common, but poorly understood by the lay person, factors.
When it comes to kWh, efficiencies and other things, people are generally simply not yet clued up about what is, and what isn't "sensible numbers"
BTW, an 87% RTE means roughly a 93% single trip efficiency. Which is pretty poor these days, and most manufacturers are aiming for rather better than that as i have mentioned, both the get the best certification figures, but also to reduce the cooling / thermal work required, which broadly means cheaper devices

You seem reasonably intelligent
Think of as many reasons as you can why I might, then think of as many reasons as you can why I might not.
The only reason I can think of is that you have no knowledge on this subject at all. Evident by the evidence you have provided too.Think of as many reasons as you can why I might, then think of as many reasons as you can why I might not.

So 5 minutes ago it was too expensive but that's total bullcrap as at your prices we could have 10 times the amount of filling stations for the cost of one train line........ and you have the gall to question what i've said......LOLOLOLOL
Sorry, you may have missed my question earlier: What does HS2 and hydrogen fuel stations have to do with each other?
t then?Literally five seconds of thought should be enough to show that the place for H2 storage is directly AT the point of renewable electricity generation. This is because you want to move the least efficient point in the system as far upstream as possible to avoid the multiplying effect of the low efficiency part acting on your distribution network.
ie say your distribution network is 90% efficient. Move 100kWh and you "loose" 10 kWh. But move 200 kWH and you loose twice as much (which is why percentage efficiencies do not tell the full story. So if we have H2 cars, that use between 2 and 3 times as much energy at a vehicle level, we loose twice as much energy in the transport network.
So, put the H2 storage system next to the wind turbines and solar farms. Make hay whilst the sun shines and the wind blows, and use that local but mid scale storage system to boost the network when the sun isn't shining. Safer, cheaper, more efficient. An absolute no-brainer.
It should come as no surprise that this ^^^ is exactly what is happening........

Another clue Braddy my sarcastic little flower is that neither v2g or hydrogen solutions to smooth the demand spike in the grid in the evening happening any time soon so that’s all good then isn’t it….and then when things are in place legislation will drive take up. Do keep up dear boy
Odd. V2G is already being used. Interesting numbers from those doing it

Genuine question - why would I want a smart meter?
............
so we just read two numbers and send the readings in when asked to by our electricity supplier.
Well that would be enough for me. ............

I get not everyone would like to be alerted to things like a sudden spike like a leak in the gas or sudden boiler inefficiency - and some people like to get sudden surprises from their electricity provider that they then need to squabble over for months.
But mostly, the data is pretty interesting. Combine it with the grid intensity figures and add some disaggregation and you can change your impact fairly substantially. It would be interesting when there are price plans available based on time of use and carbon intensity. Then imagine having something with a big battery that could smooth out your draw from the grid. Perhaps even sell green energy back to the grid for a profit. But no, its too hard.

Why don't you tell us how many people in the UK are using it then.....
(BTW I don't disagree at all that the technology exists and in principle 'could' eventually work nationally and in a small controlled sample does work now)
I have no idea how many in total, but your mates at the National Grid should be able to tell you that. (BTW I don't disagree at all that the technology exists and in principle 'could' eventually work nationally and in a small controlled sample does work now)

And as for batteries, the current tech works. It's just not efficient or superior to petrol in any way other than local pollution there is a reason why humans are the master species and that is because even the dumbest one can adapt easily and rapidly to changed environments.
Absolute bunkum, sorry!A current EV uses around 3 times less energy over it's life time to provide a faster, quieter, cheap to run, easier to drive, bigger interior space, lower maintainance passenger car than the equivalent ICE.
For most people, that's more than enough.
