Things are Starting to Warm Up. 21

a sign of things to come... hold on to your hats, folks.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Do you feel any better?

SCOTUS...could anything be more political !?

More seriously though dik, I get that you have a block about seeing my contention that the climate crisis and mitigation are inseparable from politics. You are a non-partisan anchor of common sense here, and it is your thread, so I will commit to avoiding any direct or indirect mention of politics for the balance of this thread. Since I also do not indulge in selective data-crunching exercises (i.e. amateur climate scientisting), it means I am done here.

Cheers.

p.s., when I see the singularity approaching, what I see is our collective cranium disappearing up our collective large colon, accelerated by the Interweb Babel. Can't think of a better metaphor.

I'd say Greg is the non-partisan anchor. He merely provides data and little speculation. Dik is just as partisan as the rest of us.

Speaking of SCOTUS. A major win with W. Virginia vs. EPA. We are returning law making to the elected legislative branch and stripping it away from an appointed bureaucracy with no checks or balances. It's a restoration of our Democratic rights. The again, climate change cannot be addressed with democracy standing in the way.

Although there is general scientific consensus that measures are needed to avert global warming and possible consequent ecological disaster, forming and implementing policies for global warming is likely to be more difficult than has been supposed. The reasons lie in the nature of the threat and the radical mismatch between it and the types of problem normally faced by democratic governments.

 

[dik]

Partisan only in that I have a high degree of confidence that climate change is real, and that there are potentially some serious changes that need to be done. I see little (for real) happening and I fear it will get a lot worse. The data I provide is generally correct.

Politically, I'm a conservative with a high social conscience. One of governments few purposes is to provide for the long term safety of their people and they have failed miserably with this.

Off my apple box.

so in im's list of politic points ... none of the quotes were from im ? hummm ...

another day in paradise, or is paradise one day closer ?

@TugboatEng Thanks for the link to the science direct article by Ian Christie, I was able to find a copy on acedemia.edu and I am in the process of reading it.

This point doesn't ring true for me. We know we need action to mitigate the effects of climate change, we had a government department being led by democratically elected officials, supported by the majority of the population, tasked with protecting the environment and they put in place legislation based on scientific data to move things in the right direction. Do you know if the SCOTUS decision was based on any consideration for the changes necessary to reduce the impact of climate change?

 

[enginesrus]

Carbon has nothing to do with anything other than helping plants grow etc. the sun does not run on hydrocarbon fuels, so we have nothing to worry about. Follow the $ and the reasons for climate change will be found.
Actually we are now living it. Top buck for energy now and all that follows.

I sure hope you're right, but I don't think so. "When an ostrich sticks it's head in the sand, you know what's exposed", is an old expression that comes to mind.

This is interesting:

Climate change: 'Sand battery' could solve green energy's big problem -

Politicians like to panic, they need activity. It is their substitute for achievement.

 

[dik]

Thanks pud... it may even be useful for cold climates like Canada... possibly part of a solution.

Things are starting to heat up a bit... I don't like temperatures that are much in excesss of 20C...

The "sand battery" appears to be only effective as a means of providing stored heat, and as such, requires central heating. Otherwise, you'd have to generate electricity to distribute the stored energy, which incurs losses.

Yup... and that may be one of the things that may change in the future. Canada is not like Iceland.

No capacity specifications or estimates for the existing sand battery. I'm going to assume this is another fantasy at this point

 

[dik]

It's just a means of storing heat... if sufficient it can act like geothermal stuff...

And heat can be quantified.

 

[Tomfh]

I hope this sand battery works. It seems a plausible idea. Sand is cheap and plentiful, and could be a reliable heat reservoir..

It says it can keep the sand at 500C for extended periods. Couldn't that be used to generate electricity?

 

[IRstuff]

generating electricity from boiling the water into steam, then spinning turbines is not a particularly efficient process, particularly since the sand can't move.

For this to work there has to be some way to circulate the sand. I'd assume there is some conveyor system that runs the sand by heat exchangers. At 500°C, the Carnot cycle efficiency for steam turbines is quite low.

I'm not shooting this technology down yet. I have experience similar technology when pulling a plug on the bottom of a boiler furnace and can personally attest to the high temperatures that remain in the ash for quite some time after shutdown.

But, if the unit is operational there must be some performance numbers available.

Sand has a specific heat ~1/5 of water.

It doesn't need to be, hence all the coal and nuclear power stations out there.
