Electric cars

Oh dear! Mind your head on that wall. :

Care to find me an engineering or scientific source that states that a liquid fuel rocket motor is not an internal combustion engine?

Just one will do.

Good grief! I'm a non-technical girlie modern history graduate, albeit I've been around a bit. If you don't appreciate the import of the E in ICE, it's not much point trying to enlighten you.

Rockets, other than cold-gas thrusters, are a type of internal combustion engine

Hi

Agreed, however, there is a huge difference between 'is a form of' and 'is' and the two should not be easily confused ...

When referring to an 'ICE', there is acceptance as to what is being conveyed (an engine to convert chemical energy to mechanical energy through a process which is fully contained within the engine itself), just as there's acceptance & understanding of meaning in the case of 'Diesel', 'Jet', 'Rocket', 'Pulse-jet', 'Turboprop', 'Turbofan' etc ...

Anyway, let's not fall further for the normal diversion & distraction tactics being used in an EV thread by those opposed to EVs and get back on track with a positive report on the latest predictions from National Grid ....

This time last year National Grid data estimated that the electric cars could increase peak demand electricity by as little as 8GW by 2030.

In its latest report the same amount is likely to be needed only by 2040 if consumers charge vehicles at off-peak times and through vehicle-to-grid technology.

... interestingly, this detail is released & reported on just days after the government were told by an influential technical body that their plan for additional nuclear generation should be reviewed on capacity & cost grounds .... looks like momentum is building for the pro-side in the EV debate!

# Noted the additional ..." main combustion chamber" etc .... have a look at what process happens in the thrust chamber in the cut-away diagram & consider whether that's also internal ... it's not as if it's an exhaust pipe! .. as mentioned, 'a form of' & 'is' are different!

"as little as 20%". Oh, well, there we go.

Hi

On the contrary ... although adding 8GW represents around 15% of current capacity, that's not what's really being reported ....

What they are saying is that given the same rate of EV roll-out, the full provision of an additional 8GW of generation capacity won't be necessary for a further decade, therefore almost doubling the time available to build capacity ...

What really needs to be recognised is that the uptake in EVs in the decade between 2030 & 2040 will be far greater than the decade running up to 2030 therefore the implications on total eventual capacity to cope with close to 100% of vehicles being EVs (whenever that may be) is huge ...

But of course, in things related to the supply of electricity, the obvious retort from those posting in opposition to EVs would be to claim that they in some way know better than National Grid ... fine, I'm all for an alternative, however I suspect that the power expertise at the National Grid don't have much to fear!

Couple of news items:

Researchers In Norway Claim Lithium Ion Battery Breakthrough

The discovery will lead to batteries that can power an electric car for 600 miles or more, the researchers claim. “You can say we have found the X factor we’ve been looking for. This has enormous potential and is something scientists around the world are trying to make,” says IFE research director Arve Holt, according to a report by Bergens Tidende.

Electric Trucks Are Coming

Many people still doubt that trucks will become electrified. But according to financial energy specialist Gerard Reid, the adoption of electric vehicle technology in the freight sector will take place faster than expected. He gives four reasons why he is positive about electric trucks. Courtesy Carbon and Energy blog.

That's a bit poor of Hyundai. It's almost like they have no faith in the marketability, and have it more as a publicity stunt than a viable model.

I presume there's a reasonable drivetrain crossover with the Kia Soul EV.

I'd say 'that's a bit poor of Hyundai UK, or their dealers'. Hyundai, the car company, has gone to the expense of actually designing and attempting to build the thing. Lack of dealerships to sell and service the EV (including salesmen) lets it down. Same story for Kia - they have 13 dealerships in the UK that can service EVs. It'll be similar, but perhaps not as bad, for other manufacturers. EV servicing is still specialist, because <2% of cars on the road are electric. Specialist, not complicated.

And yes, I can see similarities between the Leaf and my Soul EV (similar dashboard readout, 3 blue charging lights on dashboard), and in turn, the software on the screens look very similar between the Soul EV and Ioniq EV - there'll be plenty of shared/evolved tech underneath too.

"as little as 20%". Oh, well, there we go.

That should not be translated to 'we need 20% more power plants' - that's not the case. Power plants are utterly awful at dealing with peaks and troughs (try switching one off and on again!). Leave power plants running all the time for efficiency, use wind, solar, hydro and batteries to deal with peaks and troughs. Likely more locally than we're used to. I didn't even mention vehicle to grid but you can file that under 'batteries' above.
