I wouldn't give a penny of my money to Elon Musk, however distant the transaction.
I live in London and I'm seriously considering going car free and I LOVE cars. I can (and do) walk or cycle to pretty well any daily destination - shops, doctor, dentist, pubs, restaurants, cinema,...
I'm not in the least bit interested in an EV but there is no chance that hydrogen or ammonia will be anything but a niche solution for private transport. The energy efficiency is so much lower than...
Though if you want your battery (or solar) system to power your house in the event of a power cut you need your house system setup for "islanding" in order to do so. Its kot automatic, as normally...
Agreed, that is certainly a good point and a viable use case.
I’m pretty sure battery swapping is a dead end - it’s too restrictive in terms of vehicle design and manufacturer specific requirements. Improvements in battery tech in terms of range/capacity and...
That’ll be a long wait I think …
It’ll pass, it’s the usual Luddite push back against any new disruptive technology.
Given the effort that is devoted to vehicle packaging and space efficiency I would be quite surprised if that was really the case.
In any event the required shape of high pressure hydrogen tanks...
My point was not about range but about the internal space taken up by the hydrogen tank - and was responding to an earlier comment that fuel volume didn’t matter only the mass, however, for a private...
Except in personal cars where the volume is rather important - I don’t think hydrogen will ever be viable for cars. Large vehicles like trucks, earth movers, construction perhaps.
Indeed they are though largely because there is significant government funding to support it.
As I say it’s likely to have a part to play in the total transport portfolio, but with 15,000 hydrogen...
It’s certainly not hydrogen. Too many compromises and inefficiencies for cars; possibly a solution for LGV and similar.
Yes, in principle you can set the priority for supply, I’m not aware of any minimum amounts, quite often you will see small rates of charge to the battery - every little helps! I don’t have an EV but...
Well, depends on the exact situation/layout I suppose but my house is three storeys as well and they were installed just using ladders ... each panel only weighs a few kilos and the fitter just...
Ah, OK so you would be using the car as the “battery” to store the excess production during the charging day. That makes sense though as I say I doubt if a 14 panel system will actually produce all...
Can I confirm the bit on bold do you mean you/your house use about 25 kWh per day?
As if so there is little to no chance that 14 panels will supply that with anything left over.
I have a 12...
God, yes, and a more inappropriate car for the transport challenges Barnes presents (not) it is hard to imagine!
You are probably right - as I say I don’t have an EV so it is merely what i have observed.
Regarding Putney Exchange, I remember when those went in, didn’t realise they were free to use (though...
I live in Barnes, so adjacent borough to Ryan and we seem to have loads of chargers, including the lamppost ones that I assume are very slow. I don’t have an EV and no way of charging at home, but...
Thank you for that - a very interesting read. Certainly if something like that can be made to work cost effectively it would be a game changer. I find it slightly surprising that there seems to be...
I’m very dubious about hydrogen for ordinary cars in any form.
It seems to me it has three big problems:
1. Making the stuff*
2. Distributing and storing the stuff*
3. Using the stuff*
* where...
That is of course “mostly” true. Perhaps I should have said “... are the norm ...” and “... nobody needs to own an every day car.”
But he needed it now not in 5 or 6 years time - his point was that today an EV could not meet his needs (including the purchase price).
I find the religious fervour on this topic fascinating ......
