Brexit, for once some facts.

At maybe 5% efficiency!
.

The energy needed for the adsorption process concerning the CO2 is very little, it's mainly electrostatic.
the energy needed for charging the battery is recovered later so efficiency in this particular cycle is near 90%-95%.
In the future, they may develop the process without needing the battery.

 

[oyster]

Other residues also need to be scrubbed off the exhaust gas before separating CO2.
recovered CO2 can be disposed off where it's more suitable to do so. You can pump it into the soil where it can be digested or freeze it for example.
This method shows us a promissing technique where CO2 can be removed efficiently using a small volume and relatively lightweight equipment. At the moment, your e-cars carry a 200kg-300kg kit to do just that: removing CO2 from the city to release it elsewhere.

Inject it in the soil - and then what happens?
Freeze it - and then what happens?

I know some inejct-into-rock approaches exploit an inherent possibility of chemical combining. But anything else could end up just being a long-winded way of slightly deferring release. Shove down an oil well - then it bubbles up over however many decades.

Grow things ... Lets say timber or bamboo, and store the timber. CO2 gone efficiency about 2% . Oh and make things from the timber .and bambo...like aircraft, buildings, underwater.

Managing to incorporate a large proportion of the carbon dioxide is going to be difficult. I know higher carbon dioxide levels can result in higher growth rate. But what percentage can be incorporated without significant loss to the atmosphere (e.g. simply due to greenhouses which leak)?

And you can imagine the ludicrous idea of growing things - especially timber - and then seeing the product sent to Drax to be burned!

I don't know which is best method to recycle CO2 but we do use CO2 to make fertilisers, building materials and fizzy drinks.

Britain is slowly waking up to the truth: Brexit has left us poorer, adrift and alone | John Harris

CO2 is a by-product of making fertilisers, isn't it? That's why there have been CO2 shortages when fertiliser plants are not operating.

Many building materials emit a load of CO2 during manufacture. Cement and the classic, lime, for sure.

And fizzy drinks only hold the CO2 in the bottles/cans until they are opened. Highly transient.

We'll see. I'm a cynic where all new invention announcements are concerned. I doubt one in a thousand ever come to fruition.

No, they are almost certainly The Glistening Inkcap, Coprinellus micaceus. Like all the Ink Cap mushrooms they deliquesce into black ink.

If you want black food, think squid ink which is safe to consume.

I will almost never say a fungus is safe to eat. Partly because identification isn't easy and especially so online. (And I know enough to know I am no expert.) But also as in this passage:

From tree stumps or buried wood of broadleaf trees, Coprinus micaceus, formerly known as the Mica Inkcap but now called the Glistening Inkcap, arises in small to medium-sized clumps from spring until early winter. This edible mushroom is potentially poisonous if collected from roadsides or polluted land, where the mycellium can bioaccumulate heavy metals such as cadmium and lead; this results in the mushrooms containing high concentrations of these toxins.

Indeed, both these comments go for all mushrooms. We can say they are not safe to eat from online photos, but can never say they are safe to eat.

The name changes add another danger, that of misidentification. In this case the Coprinus family name has also been superceded, by Coprinellus.

Not at all ludicrous. The advantage is that Energy gets stored and then consumed when it makes the best use. But the new difference now is that PV related systems are now more efficient in production

It is ludicrous as a way of taking CO2 out of the atmosphere.

It isn't ludicrous as a part of a whole continuing cycle fully thought through and carefully implemented.

If you mean the ban coming in 2035, yes it is wise.

Already quite a few who've bought them often don't bother to charge when it's inconvenient, treating them as nearly full time IC cars, and the electric range of most models is very small.

But the real problem from 2035 would be those who buy them only intending to use them as pure ic cars to get around the ban on IC only.
.

Those are behaviour issues and there must be plenty of ways for govt to make this kind of misuse unattractive.

One that I'm thinking of is to regulate towards the norm being a capable 50 mile EV with a small IC engine for occasional use, a bit more than the 40hp it takes to keep a car moving at 70mph. There'd be some variation of course but gross exceptions for private use would be hard to obtain.

These days it takes a 250 mile battery to sell an EV in preference to an IC car, when either is likely to average 20 miles a day. That sets a pattern until at least 2035 and doesn't sound like a convincing low carbon outcome overall.

Would hybrids become acceptable or is this just too controversial?

And while the tories fixate on themselves, there's a quite serious mortgage crisis meets recession quietly lurking closer. In USA they argue its inflation rather than debt fuelled and absolutely fine, and different from 2008

How Bad Could the Next Recession Be? | Morgan Stanley

If history is any guide, an inflation-triggered recession would be less severe than one caused by credit excesses.

www.morganstanley.com

I'm not at all convinced that's true in UK. Its overinflated asset prices, again, and unsustainable debt. The fact that the numbers are different is immaterial.

What the hell are Morgan Stanley playing at? It's very different - inflation exacerbated by war.. for as long as it continues. Therefore it isn't "absolutely fine", and won't be for years - even after it ends. The UK is a much smaller kwasier economy, where property prices have been kept high by hook or crook... about 36-42% of all "Wealth" is in property here... people have become somewhat dependant upon it's overinflated value. Has our economy actually recovered from 2008?

It's a MS advert to increase brokerage revenue through diversification of portfolios. The MS TV ad should have been made by the team behind M&S's Christmas campaigns - "This isn't just inflation... this is war inflation," with visuals of tiny mangled cadavers and bloody human body parts being tipped over a slow rising mushroom cloud, using a giant white jug.
