Re: long duration storage with liquid air

Are you agreeing with MikeNowak - who seems to be saying that scaling this up won't work because (if I understood it right) large volume storage of liquid air demands such high pressure that the container becomes either unbuildable or disproportionately expensive? If that's so it's a pity, as it lo...

Re: long duration storage with liquid air

Don't we have (or had) loads of air liquification and distillation plants around the UK...? I'm sure I have seen lorries of liquid N 2 on the road and delivering to scientific/research facilities - and liquid oxygen is also a regular thing. I have even done jobs on sites where other people have bro...

Re: Tesla's "cheaper car" ?

Given it's getting to be a bit elderly compared to the competition, it needs to be. Main point is that they're burning up their own margin in the process - bad place to be against Chinese competition.

Re: Cybertruck seized in Manchester

According to GMP it was seized under S165 of the RTA: no insurance. Nothing to do with being UK legal. Getting insurance if it isn't UK legal is going to be tough - as I understand it they bought it overseas (Albania?) and imported it as if they were a tourist. Insurance presumably became invalid w...

Re: BMWs to run on vegetables

I assume (dangerous I know, but I'm going to) that it's nigh on impossible to produce enough bio/synthetic fuel for the World's current ICE fleet. Plus, it won't help much with localised emissions from the tailpipe. The big issue isn't the world ICE fleet. It's that a whole bunch of industries are ...

Re: Lucid comes to Europe

If they're only selling a few thousand cars, it'll be the overheads that are killing them not the cost of manufacturing the car. IF they can increase sales, their cash bleed will go way down.

Re: Electric catamaran passenger and car ferry

but how is a battery going to provide redundancy? Given that conventional ships only have propellors anyway, I guess that a back-up generator for the electric drive would be better than that! https://www.wartsila.com/images/default-source/products/e-pms-landing-page/the-propulsion-battery-and-energ...

Re: Electric catamaran passenger and car ferry

Presumably it would use only full power to accelerate and reduce the power by quite a percentage when up to cruising speed? Analogy : Dunno about all EVs, but mine can discharge at a bit over 3C on acceleration, but at 70mph and a range of, say 210 miles, it will be discharging at about 0.3C for mo...
