Considering the government of various nations is pumping millions towards "Green" projects to mitigate AGW such as chocolate stores and other highly dubious things you can be sure that corporations and those people that see an opportunity to profit have their hands out.

Catch, make or grow everything you can.
Seawater absorbs C02 increasing acidity - carbonic acid, leading to the acidification of the oceans.
There are processes like the MIT case for removal of the C02 from seawater with low energy inputs.
C02 is already reduced, ie will not be useable as a 'flamable gas' without splitting the carbon and oxygen bonds which take considerable energy.
There is no 'danger' of excess reductions of atmospheric C02 from the processes.
If you have a link to a seawater/C02 flamable gas it would be interesting to see it.

It has been taxpayer funded in one form or another since the 30’s at least in the US. TVA mean anything? How about We Poke Along. That would be Tennessee valley authority and the WPA program. More socialist BS started by the government i the 30’s and 40’s

Funny I contacted Morningstar trying to get info but they don’t play nice with end users… they dance around your questions in an attempt to avoid answering them. So you are suggesting use an own unit in tandem with the moot units as a load diversion? I will pm you for more info… any info is good info.

Yes we are expendable that is what they are counting on

I think he was referring to used Tesla EV batteries. 24v x 285Ah or something along those lines.

Much safer than even AGM’s in some cases. I have had less issues since I swapped to LiFePo4 them when I had agm’s. Not kidding they are much better suited for solar than many other chemistry’s

You say 'Socialist' like it's a bad thing in every instance...
How about the rule of law? That's 100% socialist.
How about streets, highways, interstates?
That's all 100% socialist.
How about clean water supply, sewage disposal & treatment?
That's all 100% socialist.
The right to travel inside U.S. Borders?
That's all socialist.
The U.S. Constitution, Bill Of Rights are socialist agreements.
The word Society is where socialist comes from, you can't have a society without socialist agreements... People have to agree on things collectively to have a society.
Just don't fall for the idiot propaganda, it's all in how those socialist agreements are used, the collective resources are obtained and allocated, and how much benifit the general population sees from these agreements and projects...

Charge density, but return on charge input.
I battled with lead/acid and the voltage drop issue for 25+ years...
Lithium changed all that, it just took WAY too long to get through my thick head to accept that. 3X to 5X the RETURNED useable potential before voltage drops off.
It used to be enough panels to desperately try and get lead/acid back to 100% SOC so you could do extract 25%-35% of RATED Ah,
And let's not forget all the corrosion/maintiance issues, the space/weight issues, the explosive gasses issues...
With higher output panels/increased production dumped, and I do mean DUMPED, lithium readily absorbs high charge rates/faster recharging...
Lithium chemestry batteries that will readily accept the production, and then return the full rated capacity WITHOUT the 25%-35% voltage drop off, resistance losses, there is so much more USABLE capacity it's practical AND cost effective (over time)...
I'm excited to see what's next after watching every Watt for nearly 30 years!
I'm OLD, so this stuff interests/entertains me.
It's quite nice to have a 3X to 5X reserve ready and waiting... I want to see what's next!
Many of you guys can't imagine a vehicle 12 volt starting battery with a 12 month warrenty you had to pre-heat the car AND battery to get the car started in winter,
Or 6 volt 'Lantern' batteries half the size of a car battery for weak flashlights, but some of us lived through that crap...
Hell, I'm still waiting for my bionic body parts, flying cars, jet packs we were supposed to have by the 1980s... ?

So these companies are not really in the energy business, they are more into the financial business and we fund it.

A lot of their decisions are based on that financial model. There is no incentive to keep rolling stock past the time that they are fully depreciated. Do you ever notice their trucks always look fairly new? Unfortunately that is not the case with infrastructure like the power distribution system.

And here's one of them examples of PG&E's "fully depreciated" rolling stock.
K2500, 6.5L turbo diesel, Allison transmission. No A/C, but it does have a block heater.
10 years ago at auction cost me $3400 + 10% buyer's premium. Then $500 for 4 factory-new tires and aluminum rims (someone bought a new truck, paying in sales tax what I paid to buy mine, and drove straight to the tire shop for balloon tires.)

'Business', by definition, is to make MONEY.
Capitalists objective, by definition, is to aquire or control ALL capitol (money).
Controlling money means cutting corners, wages, getting everything done as cheaply as possible while charging the highest prices they can get, increasing profits that consolidate at the top.
Someone mentioned the TVA.
The TVA started as a government funded jobs program to pull the U.S. out of the Great depression/dust bowl, AND create low cost, non-polluting energy grid at the same time.
When people talk about the "Great Depression" /stock market crash of 1929/1930 they don't realize it was Capitalist Speculation that caused the entire thing, Capitalist law makers took all breaks off, removed all checks & balances, and Capitalists drove the bus right off a cliff...
That WAS recoverable, like every capitalist blunder, the citizens would SOCALIZE the losses, pick the economy back up by the bootstraps and continue on...
Except... being an agrarian based economy, the Dust Bowl happened on top of the market crash. This crippled middle America, average Joe & Jane's ability to pay for the mistakes of capitalist speculation as it had in previous crashes/depressions.
Then came WWII.
The TVA power was essential to building the nuclear weapons program, along with steel production for conventional weapons, and the propellants/explosives.
After WWII the TVA returned to mostly civilian use, but was still critical in national defense/strategic defense programs.
People crap on the TVA as a government money dump, but 1/4 of ALL energy used in the U.S. is for military/defense, so it's still VERY essential in that environment.
You really can't have a bunch of greedy, private energy company screwing with national defense everywhere, letting the power grids decline/fail, running them on a shoestring with no spare parts, obsolete equipment, etc.
I mean the second largest wide open to attack national defense grid is the power grid computer controls, we have known about this since the 90s, and the grid owners refuse to secure the computers and computer controlled equipment because it will cost "Millions" to the largest & most profitable businesses in the history of mankind...
All the while these big energy companies are getting billions in tax payer funded abatments, tax credits, grants, etc.
There is a reason the Department Of Defense (DOD) and the U.S. Military have an objective to go renewable energy and local power grids, it's sustainable and it's WAY more secure.
If you don't remember, one idiot flipping switches in the wrong order blacked out most of the east coast and parts of Canada not too many years ago...
Failure to add $100 heaters to gas regulators blacked out most of the Texas power grid a couple years back for over a week...
You can cheer on 'Capitalism' all you want, but there needs to be some common sense and some limits how cheap they are allowed to get in the name of share holder profit margins...

I had a neighbor back around 15 years ago whose brother or cousin or some relation installed solar for him with 12v FLA. He absolutely hated it. Constantly monitoring battery fluid levels and ongoing problems, partly due to a poor installation. I took one look and said no way I'm dealing with that. Then LifePO4 became an option and everything changed for me. That and this forum.

That is an important fact which is not often mentioned with regard to the Texas power grid failure. The native moisture in those gas lines froze which knocked out the fossil fuel generation.

here is one on ebay I found, yes in the US
this one is a Revision C, 2017 or later
TESTED w WARRANTY 5.3 kWh Tesla Model S 85 90 EV Battery Module 24V Gen 2 Cells | eBay
They are backward compatible and will fit 2012 to 2020 Tesla Model S and X with proper knowledge. Beware of Gen 1 modules as they are aging out at 10 to 12 years of age and failing. Total energy storage is 5.3 kWh.

I worked with Lithium before I knew what I was doing... Didn't understand the dynamics and was looking to replace my aggravating lead/acid storage (off grid).
This is the pitfall of not having a formal education, you have to hammer it through your own optics/experience (thick head).
I'm thicker headed than most... ?
First it was the obstacle of getting mostly 12 volt Lithium batteries in the beginning when I was 24 volt and converting to 48 volt.
Then it was educating myself on BMS units, and what happened when you force charge Lithium-ion.
Burned my eyebrows off learing lithium-ion electrolyte burns on contact with air...
For 30 years it was trying to get enough panels to charge lead/acid during peak sun hours with lead/acid having higher resistance the higher it charged, so BIG losses trying to get that last 10% charge into them...
Just to have the voltage drop off to unusable amounts really quickly. Storage isn't storage when you can't extract useable levels...
So, Lithium charges REALLY QUICKLY, way less losses, and doesn't degrade when you don't get 100% SOC...
AND they give 100% RATED power in USEABLE voltage...
What kind of witchcraft is this!?
I would have raised an eyebrow while saying that the first time, but I burned them off... ?
People complain about 100 pound Lithium battery weight when it commonly took 1,000 pounds (or more) to do the same job with lead/acid.
I call Lithium a win in the weight category.
Just an old man rattling about the past, but it does put things in perspective sometimes...

Those are not LiFePOs. They are much more volatile than LiFePOs.

Same here,
In 2001 saw the set up from a guy I bumped into via my work, and he invited me to see "his super 100% off grid system"
All used Lead Acid batteries questionable set up and constant maintenance, I said "thanks for showing it to me". Then didn't follow suit.
About evey five years (for two decades) I would look into the whole solar as an option thing, and it never made sense for us, always came back to the batteries would not last long enough to justify their own expense. Then in 2019 this pretty quickly all changed! I was getting excited after seeing a few of Will's earlier videos, and thought, hey maybe after 20-years, this will finally be possible!
So jumped in and got started, joined the forum, and here we all are! exciting times, and I bet we are just in the beginning of a long run of new products, new tech, better PV/batteries/inverters I can't wait to see what comes out of the new EV industry and world-wide interest in solar.
