I doubt that supercaps will ever achieve the energy density of
batteries, and if they get close they will be equally explosive.

People are inventing super "capacitors" that sound awfully
electrochemical to me.

The threshold for a press release seems to be to make something that
will light an LED, which takes about a microwatt.

Yes, new batteries are invented every week it seems.
Now super capacitors too
We will have to wait for it to be in the shops.

Methane has half the carbon of a long-chain liquid hydrocarbon. In
most situations, a 2:1 improvement is considered to be pretty good.
CNG cars work. But the greenies hate methane. As they hate nukes and
hydro power.

They hate energy.

But in the current situation a 2:1 improvement isn't good enough.

We have to cut our carbon emissions right back to stop global warming -
the aim is to get the atmospheric CO2 level back to the regular
inter-glacial 270ppm.

For good reason.
Post by john larkin

For very different reasons.

They aren't enthusiastic about nukes - we still haven't got an
acceptable way of dealing with nuclear waste. It does stay dangerous for
abut 100,000 years.

The aren't all that enthusiastic about flooding valleys to create
hydro-electric reservoirs. It does mess up the local environment, and
always seems to drive some species or other to extinction.
Post by john larkin

They don't. They just have reservations about some of the ways we
generate it.

This is good example of you expressing yourself clearly, but expressing
unfortunate opinions you have picked up from climate change denial
propaganda, which you should have been able to recognise as fatuous
nonsense but have swallowed, hook, line and sinker.

That would only stop man-made global warming, which is a tiny fraction
of the overall effect. Volcanos, forest fires and decomposing
vegetation have far more effect than mankind has.

What mankind has done to apparently increase 'global warming' is to skew
the data collection and statistics, supported by (and supporting) a
growing industry of self-appointed environmentalists.

Then why don't they oppose tree planting and support the clearance of
forests, which are the biggest source of methane when the trees and
other plants die and decompose?


I definitely think we should be less profligate with our natural
resources, but we should not be treating it as a religion and proposing
feel-good knee-jerk 'solutions' which haven't been properly thought
through.

Rubbish. The natural CO2 cycle does dump 790 gigatons pf CO2 into the
atmosphere every year, but it also takes it out again.

About 60% human generated 29 gigatons per year stays in the atmosphere,
while 40% dissolves in the oceans.

https://www.che-project.eu/news/how-do-human-co2-emissions-compare-natural-co2-emissions

The human generated CO2 is low on C-14, and that started messing up
carbon dating around 1945

Not really.

https://climate.nasa.gov/vital-signs/methane/?intent=121

NASA blames natural processes for 40% of the current emissions and human
activities for the other 60%, which is why atmospheric methane levels
have more than doubled over the past 200 years - you can get that number
from ice core data.

Since you didn't check your claim before you posted it, you don't seem
to have done a proper job of thinking about what you posted.

And John Larkin's claims about what greenies think come from climate
change denial propaganda. I've not heard any real greenie say anything
anything like that stupid.

There was an other bunch of greens chaining themselves to a museum entrance in Amsterdam last week.

I think their argument was that ING bank had something to do with CO2 and financed the museum?

The "greenies" that John Larkin fulminates about don't actually exist.
They are an invention of the climate change denial propaganda machine.

If John Larkin had ever had a proper education he might be able to
distinguish truth from concocted stories. Perhaps not - he doesn't seem
to be able to learn much at all.

It's a pretty silly thing to complain about, but the ING Bank does lend
money to people who dig up fossil carbon and sell it to be burnt as
fuel, which is an activity which we are giving up quite rapidly - if not
quite as fast as we should. The side effects are nasty, and getting nastier.

If morons glue their hands to airport runways, the appropriate
response is to instruct the pilots and truck drivers to ignore them.

Same inside museums.

You need psychopathic pilots and truck drivers for this to work, and
there aren't nearly enough of them.

It's that kind of practical detail that escapes the right-wing
psychopaths who post here. They don't really appreciate quite how
unpleasant and anti-social their lunatic propositions look to saner people.

Absent some revolutionary new technology, I suspect you may be right. Mind
you, we have people who are quite happy to only be able to drive for only
200 miles in an EV and wait several hours between re-charges. And suffer a
*massive* deprecation on their 2nd biggest asset. *And* pay a fortune to
have their old battery recycled. Fuggin' idiots.

Tesla's super-chargers are quicker than that, and 200 miles is a rather
short range for modern EV.

And electricity is quite a bit cheaper per mile than gasoline.

The "massive depreciation" is a temporary blip in a developing market.

The fuggin' idiot here is Cursitor Doom, who would still be getting
around by horse and buggy, if he could afford it.

I isn't cheaper in the UK. If you compare the basic prices of diesel
and petrol without tax against electricity without tax, electricity is
certainly no cheaper if you recharge at home and massively more
expensive if you recharge at a public charger. if you factor-in the
depreciation of the battery, it gets even worse.

Not that you have bothered to show us your calculations.

https://pod-point.com/guides/electric-car-vs-petrol-car-cost-comparison-in-2024?gad_source=1&gclid=CjwKCAjw_4S3BhAAEiwA_64YhiPZWvyTJXK_rDvTwGF4EV8_06OHAjhgHsfYEukLpko6G2r3IHrERRoCD9sQAvD_BwE&gclsrc=aw.ds

does suggest that you have got it wrong.

Figuring in the depreciation of the battery is legitimate, but you have
to compare it with the depreciation of a internal-combustion-engined car
which is also pretty dramatic, and you haven't bothered to do that either.
