In msg 2081843 I did miss out one very important problem for Boris. While we are struggling with these forced costs how is he, or his replacement, going to balance the books due to the loss if £18 billion in taxes on carbon based fuels each year.

Of course it will not be a problem for Boris, he will just find another tax to replace losses at about £550/car owner or £650/household.

I was watching a bit today on the local free to air TV here, but so far a link has yet to surface for it so I did a bit of web surfing instead for a bit more info.

It looks like "green hydrogen" is the way to go for this country. Our current government shouts it out to the world as its way to go zero emissions, but sadly they arn't really supporting the cause all that much.

But the Australian Capitol Territory (our equivalent of Washington D.C., only much larger in size and higher in elevation, but without so many pollies) along with several companies have turned out the 1st Green Hydrogen refueling station in Canberra.

This is inline with the Territories' "Environment, Planning and Sustainable Development Directorate - Environment" policy on Zero Emissions Vehicles.

This is inline with a study by Bosch into its merits, especially with heavy transport.

BMW and Mercedes have trailed the technology here, but both worked with "Blue Hydrogen" and little is now heard about them here, but Toyota and most especially Hyundai have gone the "Green Hydrogen" way.

1 of 20 Commonwealth fleet Hyundai NEXO's has been test driven.

And I've already linked, The Australian inventions that could change the world.

It's just a shame that our current ring wing federal government's hand isn't positioned where its mouth is as it will still keep throwing $'s around trying to help out the local fossil fuel market.

Cheers.

None of what you or others do or propose will have any effect on Climate. Chaotic forces on the Sun and in our atmosphere determine the climate trends and records that have always been here since before the ice age. Yes, lets plant trees and switch to Nuclear power--plenty of other reasons to do so.

Fusion leaps closer with hot superconducting new super powerful magnets:


Fusion startup builds 10-foot-high, 20-Tesla superconducting magnet
wrote:
In 2015, a group of physicists at MIT did some calculations to rethink how we're approaching the problem of fusion power. High-temperature, nonmetallic superconductors were now commercially available and could allow the generation of stronger magnetic fields, enabling a simpler, more compact fusion reactor... they formed a company, Commonwealth Fusion Systems, and set out to put their calculations to the test.

On Tuesday, Commonwealth Fusion Systems announced that it had hit a key milestone on its roadmap to having a demonstration fusion plant operating in 2025. The company used commercial high-temperature superconductors to build a three-meter-tall magnet that could operate stably at a 20-[T]esla magnetic field strength. This magnet is identical in design to the ones that will contain the plasma at the core of the company's planned reactor...

... "The vision is simple: Can fusion energy be in time to make a difference to climate change?" said Dennis Whyte of MIT. "That's what everybody on this team was dedicated to going toward. Fusion is the energy source that the world needs, and it needs [it] kind of fast. And we're on the brink of harnessing that for humankind."

Waiting for decades to get to fusion will allow renewable power to expand its current cost advantage over all other forms of energy generation. And the time will give engineers opportunities to learn how to manage the challenges of the intermittency of wind and solar power. In this timeline, fusion risks being irrelevant by the time it's a solved problem.

That's why by 2025, Commonwealth Fusion Systems wants to have a reactor that will break even—i.e., a system in which fusion reactions release as much energy as is needed to start them. That milestone will be followed by what the company hopes will be a commercially viable fusion plant in the early 2030s...



Way to go! And sooner!

The race is on to outdo the already older-tech ITER...

Martin

World’s biggest factory to suck carbon from the sky turns on in Iceland
Orca system mixes greenhouse gas with water and pumps it underground
The world’s first and largest factory to capture and convert carbon dioxide from the air into stone began operations in Iceland on Wednesday.

The Orca plant set up by Swiss startup Climeworks AG to reduce the effects of the greenhouse gas on the planet represents a milestone in the direct air capture industry.

While Climeworks has built 16 installations across Europe, the Orca plant is the only one that permanently captures and stores CO2 rather than recycling it.

According to Climeworks, every year the factory has a capacity to capture 4,000 tons of CO2, which is safely and permanently stored via a chemical process developed by Carbfix, an academic-industrial partnership in Iceland.

In this process, CO2 captured from the atmosphere is mineralised underground and converted into stones.

Monash University with support from the Commonwealth Government through the Australian Research Council and the Department of Industry, Innovation and Science has found that a little bit of sugar can make lithium batteries go further.

A spoonful of sugar opens a path to longer lasting lithium sulfur batteries.

The Monash team, assisted by CSIRO, report in today's edition of Nature Communications that using a glucose-based additive on the positive electrode they have managed to stabilise lithium-sulfur battery technology, long touted as the basis for the next generation of batteries.

"In less than a decade, this technology could lead to vehicles including electric buses and trucks that can travel from Melbourne to Sydney without recharging. It could also enable innovation in delivery and agricultural drones where light weight is paramount," says lead author Professor Mainak Majumder, from the Department of Mechanical and Aerospace Engineering and Associate Director of the Monash Energy Institute.

In theory, lithium-sulfur batteries could store two to five times more energy than lithium-ion batteries of the same weight. The problem has been that, in use the electrodes deteriorated rapidly, and the batteries broke down. There were two reasons for this -- the positive sulfur electrode suffered from substantial expansion and contraction weakening it and making it inaccessible to lithium, and the negative lithium electrode became contaminated by sulfur compounds.

Last year the Monash team demonstrated they could open the structure of the sulfur electrode to accommodate expansion and make it more accessible to lithium. Now, by incorporating sugar into the web-like architecture of the electrode they have stabilised the sulfur, preventing it from moving and blanketing the lithium electrode.
It can be good to be a bit sweet. ;-)

For another small bit of positive noise:


Boris Johnson: Humanity is reaching a turning point on climate change
wrote:
A climate summit of world leaders in 40 days' time will be the "turning point for humanity", PM Boris Johnson has said in a speech to the United Nations.

He warned that global temperature rises were already inevitable, but called on his fellow leaders to commit to major changes to curb further warming.

Four areas needed tackling - "coal, cars, cash and trees", he said.

Countries must take responsibility for "the destruction we are inflicting, not just upon our planet but ourselves".

"It's time for humanity to grow up," he added ahead of the UK hosting the COP26 summit in Glasgow.

The prime minister also said it was time to listen to the warnings of scientists. "Look at Covid if you want an example of gloomy scientists being proved right."...

Does that add up to:

    Fine words?

    All just hot air?

    Positive action?

    Soon enough??

Where all the protest groups have seemingly failed before, despite some very big splashes in the mainstream news, here's hoping this latest group make enough of a news splash to prompt some useful positive immediate action:


Port of Dover: Arrests made as Insulate Britain blocks port
wrote:
Seventeen people have been arrested as climate activists blocked the Port of Dover, causing queues of vehicles attempting to cross the Channel.

Insulate Britain, which has brought chaos on the M25 five times in the past fortnight, said more than 40 people gathered at Dover.

The port - Europe's busiest ferry terminal...

... Insulate Britain also held a demonstration outside the Home Office's Westminster headquarters.

A government spokesman called the port protest "guerrilla tactics" and said the campaigners had "wreaked havoc" in recent weeks. He added: "Peaceful protest is a cornerstone of our democracy and there will always be space for people to make their voices heard, but that is not on busy roads or at a vital port..."

... Insulate Britain, which is calling for government action on home insulation, said: "We are blocking Dover this morning to highlight that fuel poverty is killing people in Dover and across the UK.

"We need a Churchillian response: We must tell the truth about the urgent horror of the climate emergency."...


Most urgent is to clean up the home building industry that has a defacto monopoly for obscene profits in building short term cheap and shoddy homes that superficially look 'good' but are forever damagingly costly to heat and maintain. The homeowner is left forever paying the consequences of that shoddy build.

Heating badly insulated (and sometimes still, uninsulated!) homes is a very big blast of expensive polluting gas...

Note that "voluntary regulations" simply do not work for the unabashed greedy building industry...

Can our politicians 'overcome' their very cozy lobbying?...

For some highly mathematical world changing solutions:


Nobel in physics: Climate science breakthroughs earn prize
wrote:
Three scientists have been awarded the 2021 Nobel Prize in Physics for their work to understand complex systems, such as the Earth's climate.

Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi were announced as the winners at an event in Stockholm.

Research by Manabe and Hasselmann led to computer models of the Earth's climate that can predict the impact of global warming...

... The climate models that have built on the winners' research form a crucial part of the evidence on which leaders at COP26 will base their decisions.

Syukuro Manabe, 90, who is senior meteorologist at Princeton University in New Jersey, demonstrated how increased levels of carbon dioxide in the atmosphere could lead to increased temperatures at the surface of the Earth. In the 1960s, he led the development of physical models of the climate.

Roughly a decade later, Klaus Hasselmann, 89, from the Max Planck Institute for Meteorology in Hamburg, Germany, created a computer model that linked together weather and climate. His work answered the question of why climate models can be reliable despite weather being changeable and chaotic...



We have the science and the technology:

Time for positive ACTION, now!

The solution is simple. Everyone other than those that live totally off the land should move to the Moon or Mars as soon as transportation is available. A few hundred thousand natives from Africa, S.E Asia and South American would have no significant impact on the climate. P.S. Anyone willing to live under those conditions should stay too.

Improving the atmosphere here on our only one Planet Earth:


Artificial lightning zaps farm stink
wrote:
... The technology entails firing a bolt of plasma at slurry to break up toxic ammonia and climate-heating methane.

The artificial lightning is plasma – a stream of matter heated so hot that electrons are ripped away from the atoms and molecules break down.

The action smashes ammonia molecules to produce pure nitrogen, which is absorbed into farm slurry.

That saves the farmer money because nitrogen applied to fields in slurry is an essential fertiliser...

... reduces ammonia in slurry by 90%. The plasma process also reduces the emissions of methane – a potent greenhouse gas – by 99%.

If the technology proves affordable it wouldn’t just tackle climate change and improve the smell of the countryside, it would also present an opportunity to tackle air pollution in urban areas...

... The big question is the cost of the electricity that produces the bolt of plasma. At Holly Green Farm it’s produced by an array of solar panels.

But the question will be who pays for farmers to clean up...


Note also that we are all already paying very high costs by that pollution NOT being presently cleaned up...


Is that not a "no-brainer"?...
