Climate Change is here and man made

[Deleted member 77198]

Although, while Britain doesn’t fair well in woodland and peat size and volume and Manchester has that poor air quality; Manchester is aiming to contribute positively to climate change, at least in small steps.

Reported today, yet unconfirmed, that Sicily has recorded Europe’s hottest ever temperature: 48.8 degrees centigrade.

I realise this isn't the point your making but tech wise, But, Fusion, Fusion will help if and when we get it working. we could replace all electrical supplies very very quickly once we do. clean and plentiful electricity for all and the ability to power CO2 scrubbers to actively remove the CO2 from the atmosphere.

the biggest hurdle will be how to get around the legalities of patents etc if its a company that makes it 1st so it can be user globally for as cheap as possible,

Isn't the biggest issue with fusion energy that we haven't yet identified a way of containing the plasma field generated by the reaction long enough to do anything useful with it (given that it's approximately 10x hotter than the core of the sun)?

Are you still sitting in your mess from yesterday?

Banging away on that legacy laptop may distract you from the smell but it won't stop it going crusty.

Call your carer's agency if she is still not picking up.

Were in lockdown unfortunately fode no one is allowed to visit and I mean no one seriously.

Police in their thousands patrolling the streets in case anyone is outside loitering.

21 cases with 5 infectious while in the community has caused this latest lockdown because the premier reckons if we don't have a hard lockdown our hospitals will be over run despite the fact our hospitals in are empty presently in the covid wards.

The region namely the rest of the state was lockdown for 5 days on a " suspicion " of a case which turned out to be false.

Chalk up 200 days of lockdown soon and no end in sight.

The harshest lockdowns in the world of an major city since the pandemic started and from the last two outbreaks the stats are 4 in ICU and no deaths from over 400 recorded cases plus no doubt a few more because some are afraid to come forward knowing the lockdowns will continue if they do.

You may laugh at our situation but those who are sitting in the mess have no one to clean it up.

Having a PC is my salvation fode I am sure you won't be too harsh on me for that as you have been through a lot as well and I am happy you have one to use and long may that be the case.

Is that one of your deliberately garbled nonsense posts that you've put there just to see if anyone pulls you up on it, or did you not realise that it was incoherent rubbish?

No its neither westy but its good to see you are on your game today.

Honestly mate, I don’t think he’s all there.

I have no issues with using your computer as much as you see fit but maybe you have become over reliant on it for social contact judging by the garbled nonsense full of tangents and digression.

Perhaps it's time to consider living in a retirement community?

Failing that, consider some home improvements. A walk-in wetroom coupled with adult diapers will sort out the issue with your mess.

You’ll be doing the same for Bigga next!

Must admit that that reference in the rambling rant did confuse me slightly. No idea wtf Bigga has to do with anything.

Yeah from my understanding ( v limited, just bullet point level stuff ) that’s the main issue.

the record is held by China at around 101 seconds.

There are a few different types of reactors being built for testing. From massive warehouse size reactors down to reactors that could fit on a truck. these are being build by Lockheed martin Skunk works but I would guess these would be mostly aimed at Military contracts to power the US navy.

the design of the one in Germany is right out of Akira. they used supercomputer to design the best magentic field for containment and designs.

Absolutely. It's all about energy. Once we have fusion, we have effectively limitless clean energy. Not only does that at a stroke almost completely eradicate our CO2 output in itself, it also provides near limitless energy to power carbon capture "devices" - be they enormous machines, or vast bio-engineered floating algae tanks covering thousands of square kilometers, or whatever else you care to dream up.

It would also allow the removal of all hydro electric dam's. allowing water to flow to the places that the rivers used to feed.

I was watching 1 program where they were saying the Sarah desert grew in size around Morroco/Algeria due to hydro electic dams blocking water supplies that used to feed it.

Still very pie in the sky at the moment but as a species we should be lobbing as much money and resources at Fusion as we can.

CO2 Scrubbing wise I read something about some being built but were horrifically power consumption heavy at the moment. But then fusion fixes that.

Agree that we should continue to pursue fusion - at the same time - the difficulty of creating the enormous pressures/temperatures to fuse hydrogen into helium is enormous.

As unpopular as fission is - it's nuclear fission that we'll likely need to rely upon if we're to avoid a greenhouse catastrophe while at the same time meeting society's energy demands.

Again, I agree. The problem with renewables is that they just aren't available enough: no wind power when it's not windy, no solar when it's night time. OK, so we could do more with hydro and with ocean waves perhaps. But it's very hard to see how you could run heavy industry such as a steel or aluminium plant off a bunch of wind turbines. So we either have to (a) stop making stuff - hardly an option; (b) carry on making stuff and burning coal to do so - also not an option; or (c) use nuclear.

(c) is the only option and of course whilst no nuclear is completely clean and safe (even fusion) then at least fusion is safer and cleaner than the others. Incidentally I read that China is making great inroads with Thorium (rather than Uranium or Plutonium) fuelled reactors. Thorium is cheaper and more plentiful, but whether Thorium reactors are safer, I don't know.

At least with fission reactors, we know how to build them, as opposed to fusion which is still experimental. But we've got to figure out how to build fission reactors more quickly. The current lead time from initial inception to live running is like what? 20 years? How long have we been talking about Hinkley C? It's way too long. We'll have fourth runway at heathrow by then.

the lack of sun/wind is a surmountable issue when it comes to wind and solar. Im not sure why they are taking so long to build and test ( there is a test one in Edinburgh at the moment ) but gravity energy stores are a good way around how to store excess energy produced by renewables and use it when its dark/still.

This one seems to be a pretty solid idea. basically a bunch of computer controlled cranes that build a tower of heavy concrete blocks when there is excess power, when power is needed they attach the blocks to turbines and slowly lower them generating power as they drop.

One of the "popular" solutions for existing generators is to pump water into hydro dams for storage. but I personally wouldn't like to build more hydro damns to that.

I do agree Nuclear, while unpopular is needed. as you say Thorium is probably a good way to go. far less dangerous than uranium/plutonium and cannot be weaponised so the tech can be spread freely. and as you say, Thorium is very wide spread.

Molten Salt reactors seem to be a good step too.

A viable commercial scale fusion option could be decades away.

Sadly, so are any new (as yet unplanned) new nuclear power stations!

 

[grunge]

Unfortunately yep. there needs to be a stop gap. be it large scale renewables and gravity batteries or hopefully some other new batter tech.

Nuclear could be that stop gap but generally seems to take far too long to build as Chippy pointed out.

In Reality its going to have to be a mix of Renweables ( quick set up and leed time ) + fission while we get fusion going.

Energy storage from renewables and a serious increase in the efficiency of our grid and the things we connect to it is probably the best option in the short term. Whether that's achievable is another matter.

I'd happily take natural gas power stations too for the stop gaps as well as renewables/nuclear. main risks with gas is related to leaks rather than the burning it for power.

It was a natural gas leak that set the sea on fire a few weeks back!.

Grid efficiency and device efficiency is a whole other ballgame. what you dont want to end up with is people throwing perfectly good devices out to buy more efficent one. while in the long run that may help you then start to hit the side effects of disposal, manufacture, shipping etc etc. Unless said device has an insane level of upgrade to its power consumption its hard to justify unless its a "natural" update time.
