ICE phase-out delay

[grr666]

Like I said, why can't we have both? If those that want and can afford electric cars go ahead and buy them then
that's fine. Let's say about a third of ICE car drivers do just that, an approximate 30% reduction of ICE cars will
reduce the UK's contribution to global emissions down from about 1% to about 0.65% which has got to be an
improvement hasn't it? Smoke churning old bangers will disappear in exactly the same way Ford Sierras did
(once not that long ago one of the commonest cars on the roads) by just being worn out/crashed/rotted away. Only
the cleanest running ICE engined cars will remain anyway, with any new ones sold up to current Euro standards as
a matter of course.

From google - The most popular battery pack supplied by Tesla contains 7,104 18650 cells in 16 444 cell modules capable of storing up to 85 kWh of energy.

7000+ 18650 batteries in a car battery pack. Surely there has to be a better configuration for car batteries than that especially bearing in mind....

If one cell fails open, or shorts and causes the fuse wire to open, the usable pack capacity will drop about 1.4%, assuming no active recharge from the battery management system (BMS). If the cell fails as a partial short and pulls more current than the BMS can balance, the pack will ultimately fail.

Conventional batteries are two plates separated by an electrolyte, normally a liquid (which is why "Solid State" batteries should be more exciting than they sound.)

Anyhoo, this usually translates to something like two sheets of metal foil with paper soaked in a chemical in between. The two common topographic configurations are flat packs (think phone batteries) and rolled up (18650, 217000.) Even old stuff fits these two camps: lead-acid batteries use a stack of plates side by side and the AA batteries in your TV remote are rolled up just the same as 18650s.

"Why use loads of round batteries? Seems like a waste of space." True but they're easy to make to a standard, transport, etc. - a known quantity - and when making a battery pack one can utilise the gaps in the stacks to pass a non-conductive coolant.

As to improvements it's true we haven't hit the limits yet but there is a theoretical limit to any system where gains are not possible. For example the thermal efficiency of a conventional 4-stroke petrol engine is 30% and there's no way past that. "But! But! I've made an engine that can do better!!!" fine, maybe you have but it won't be a 4-stroke it'll be something else (e.g. a turbine.)

AFAIK we're about half way there with Lithium Ion batteries. If a Tesla did 500 miles now theoretically the battery tech could be pushed to do a thousand. However as with anything, it get's harder and harder to squeeze in improvements as you approach the limit so expect the range increases to make smaller and smaller jumps as time wears on. Hopefully before we approach the limit something new will have come along like solid state batteries.

Ultimately, with both batteries and ICE, we're relying on extracting energy from chemical reactions and there's an upper limit even there. Don't worry though we still have nuclear fission, fusion and anti-matter if we need more

Can't say it fusses me, we'll still be able to buy petrol, probably til I'm dead. I'm perfectly happy with used bikes

New bikes are better at some things - they're easy to ride and safe and comfortable. In terms of character and pure joy of riding they've become stilted in my opinion.

Wonderful engineering in the light of restrictive legislation but in terms of how I feel riding a new bike vs an old bike?

Doubtless they'll tax it all to hell but what's new? Governments hate everyone who isn't a toff anyway.
