Using the 4th power of axle weight formula (beloved of people spreading this myth) if you made all 34 million UK cars 100kg heavier and removed 1000x 38-tonne petrol tankers from the roads, our roads would get better, not worse.

If you’re genuinely worried about damage to roads you’d be focused on HGVs, each of which does as much damage as 5000 cars if 4th power of axle weight theory is correct.

If we all drove EVs it would take a fleet of over 1000 HGV petrol tankers off our roads.

Very significant reduction in brake dust pollution from EVs too

Even if EVs are a bit heavier than ICE vehicles they don’t need 38-tonne petrol tankers to service them, which do more damage to roads than thousands of cars (if the 4th power of axle weight rule is anything like correct).

Plus, hardly any electrons will actually cross the border anyway. And they’ll be re-exported back to Canada within one-sixtieth of a second.

I would expect A2W Monobloc installations in the UK are almost 100% for heating. In my case, the ASHP is a direct replacement for a gas boiler, and supplies warm water to radiators and underfloor heating. I don't have the possibility of using it for cooling in the summer.

Rosebank at full production would be 0.07 million barrels per day. Not exactly transformative.

If you think of oil as the world’s transport fuel you’re not far off. Almost all transport (road, marine, air) runs on oil and roughly two-thirds of oil use is for transport.

50% of oil is put in road vehicles though. So hugely significant. Less than 5% of oil is burned to make electricity, mostly in the Middle East. Petchem is around 10%, lubes less than 1% of oil consumption.

UK storage is far more than just Dinorwig. We now have over 5GW of battery storage. Dinorwig is only 1.7GW.

I think it must be million btu per hour. 19 would be 5.5kW and 54.24 is 16kW.

Do you drive an EV? My experience is that charging on long journeys is fine. You only need to charge if you’re driving over 200 miles so you need a break anyway. Yes it would be nice if it were cheaper but green H2 will always be far more expensive than electricity!

Yes uranium and actinides could be cycled, which is great! but fission products are not consumed and more are created including some with unfortunately long half lives. I just think people shouldn’t get away with saying “no waste” because it isn’t true.

Low level waste is not what a thorium reactor produces. It makes highly concentrated high level waste that includes nuclides like technetium with half life of 200,000!years.

Could be. But thorium reactors still produce waste. All fission reactors do. Maybe in a less bulky more concentrated form but still highly radiotoxic material which will be with us for tens of thousands of years.

Tell me about these reactors that don’t produce any waste. How is that even possible. I mean fission makes fission products, no?

I don’t need any road fuel tankers to be able to drive my car.

Of course there are far more cars than big trucks on the road. But I’d be interested whether switching all cars to slightly heavier EVs would create more particulates than would be saved by removing the fleet of heavy road tankers that fuels them.

I would have thought that commercial vehicles which have far heavier weight per tyre and far more tyres would create far more particulates than even the heaviest cars. Road fuel tankers for example…
