Honestly it’s hard when IM platforms are so fragmented to get the people around you to move over. I never had to convince friends to move to Lemmy to use it.
I think you’re kidding so don’t take this all as a criticism.
I mean. Literally, literally means figuratively now. People look at DVDs and say they’re not a digital copy when they are written digitally. Words are fluid and contextual so to throw out half a phrase is to throw out the ability to understand it.
Property is a system of rights that gives people legal control of valuable things,[1] and also refers to the valuable things themselves. -Property Wiki
An intellectual property would then logically follow it is a valuable thing or idea that is then legally controlled.
See that’s what gets me. You need a very specifically large load that is (in my experience) extremely rare. In the gas savings alone you could just rent a truck when you need to move gravel or large furniture and not scratch up your $90,000 truck.

There is a point though as a water cooler can cool an extremely small area better than heatpipes. Look at Zen 4 processors for instance. The CCD is so small and offset that many air coolers don’t properly line the heat pipes with part of the CPU making the most heat. Because of this Noctua even makes and sells an offset bracket to try and move the heatpipes over the CCD. Meanwhile a waterblock should cool the entire area at effectively the same rate as it doesn’t rely on vaporizing the coolant and condensing but just pushing coolant through regardless of heat saturation.
Only a fraction of people should really notice that like overclockers and generally people buy coolers they don’t need.
The Detroit Three’s union contracts will mean wage increases of 25% through 2028, which will amount to 33% when expected cost-of-living adjustments are factored in.
I don’t know how much they were making before but that looks like just enough to cover inflation over the past couple years.
I feel like most roads where you’d ride a scooter the cars would be less of a problem if they followed the speed limit. Scooters should be able to go down 45mph roads just fine but there’s always some massive truck going 60.
I’ve heart NotJustBikes say similar things. I normally don’t favor control over everything but at this point I would be ok with cars having electronically controlled speed limiters to not exceed the speed limit of whatever road they’re on.
It’s really just created such an entitled, careless, and demanding mindset where bikes need to have speed limiters on them for safety but Fred can buy a 1200hp 3 ton weapon with no limiter.
I’m perfectly fine with there being interstates that go 85mph I just don’t want people driving so fast in dense areas with mixed traffic. If I could have people just not be assholes that would be great but I feel like driving the speed limit now is just reason for someone to get angry with you and want to drive you off the road.
I’d love to ride a bike everywhere I can but every road I would be riding would have traffic going over 45mph with massive vehicles who have drivers so impatient they’d rather run you off the road than share the road.
If it make you feel better, they could do it all with one closed loop and just use the ground as the sink.
They could then power it entirely off solar panels and Iron air or sodium batteries.
But these decisions aren’t being made by people looking for sustainability but capitalists looking for profits. They’d cool their servers with the blood of children if it saved them money.
I don’t how that should make me feel any better 😀 . But I don’t know if ground is a good enough sink for that.
The ground temp in Utah for instance is like 50 degrees F roughly all year long. Coiling tubing under the parking lots of these facilities should be enough to remove all the heat and potentially melt all the snow during the winter.
I don’t think they’re going to consider renewables for cooling alone when the entire operation needs enormous amounts of power that cannot be satisfied by renewables.
I’m not talking for cooling but powering the servers. Something renewables could do if they don’t have to power air conditioning for the servers.
In the US they keep getting bigger and bigger to. I was less scared of cars while riding my bike decades ago than I am now and we had less bike infrastructure then.
Well yeah. If it was separate paths from traffic then the size of the vehicles wouldn’t really be as big of a problem. It’s just how we have to “share” with people who have no ability so share.
Solar now being the cheapest energy source made its rounds on Lemmy some weeks ago, if I remember correctly. I just found this graphic and felt it was worth sharing independently....
Much of this can be solved or mitigated with pumped hydro, green hydrogen, thermal batteries, or maybe compressed air. The problem is that all of this requires infrastructure spending.
California’s duck curve specifically can be flattened with desalination. Any excess power that California makes with solar beyond the grid’s demand should just go into making more fresh water. Having too much solar energy is really just a problem of not having systems you can turn on when you do. Even if you only get 30% of the power back with green hydrogen it is power you had too much of in the first place.
One gallon of gasoline is equivalent to 33.7kWh of electricity and your average American home uses 29kWh of electricity a day. We’ve been perfectly fine wasting energy for over a century, I don’t see why we should pearl clutch now.
As for Cali’s duck curve issue, desalination is a great idea, but expansion of renewables and storage should really come first. Keep in mind that the current Cali grid generates much less dirty power during the day, where solar covers a majority of demand. Should we divert that solar power to desalination, we would need to ramp up dirty power generation during the day, and we would continue to generate dirty power at night.
I’m not talking about using solar to make fresh water. I’m talking about using the excess power to make fresh water as to not put more power into the grid than it can use. The duck curve is often used as a sticking point for why nuclear doesn’t work, because nuclear needs a base load and the duck curve is a base load nuclear can’t accommodate.
Obviously more storage to use more renewables but also, just use the excess for something. Nuclear can boil water to desalinate, use excess electricity to desalinate via RO. Given the infrastructure you could even use this to water California’s immense farms. (But power companies like making profit so… no times of free power, climate change instead please)
While I agree with you, we also have to consider what this would do at scale. The 70% of excess power that you lose here translates to wear on the solar panel systems that is never realized into power. That is, the systems will wear at the same rate, but the amount of power you can utilize over the lifespan of the systems is decreased. It’s still a better solution than not implementing these at all, but I’d be wary as to how reluctant our society would be to the spending, especially if the ratio of cost to utilization(?) becomes skewed.
With how cheap PV panels are per mW it is not really an issue about how efficiently the power is stored. We’d obviously want to recycle them but generally the fact that you don’t pay for fuel means eventually the power is free. There was a study done in LA where if you covered just the parking lots with solar you could provide power for the entire city (if storage was available obviously)
A chemical battery will be somewhere like 80% or more efficient but they can’t hold that for weeks, months, or years.
Pumped Hydro is ideal, the Hoover Dam produces 4.5 billion kWh of electricity a year. With pumped hydro you can effectively do the same thing in places rain doesn’t do it for you. Bath county for instance has 24,000mWh of capacity. They’re obviously really dangerous if they break and also damage ecosystems.
But green hydrogen can be done mostly anywhere, stored more easily (obviously not as easy as fossil fuels or well most things) and can be transported.
I agree but I feel that is even more aspirational than renewable energy.
Personally I want high speed rail, commuter rail, trams, and bike infrastructure but I’ll probably be dead by the time any of that happens if it does at all.
I have high testosterone levels and I am always warm. In the winter I get tired of scraping ice from my car and just use my hands to melt it off the windshield.

When I first read the titile, I thought that the US is going to have to build A LOT to triple global production.

Large scale electricity storage is very much a solved problem actually. Bath county for instance has solved the problem since the 80’s.
It’s just once you take the cost of storage for solar it is no longer the cheapest power source. Our power isn’t delivered by our government for the sake of sustainability and benefiting the citizens but by private corporations who want to make profit.
The pumped hydro station I linked cost 4.36 billion USD to construct in 2022 dollars back in 1985. It also has a capacity of 24,000 mWh.
Meanwhile the F-35 project cost the US government 1.7 trillion dollars.
So let’s say new pumped hydro plants of a similar size would cost 10 billion dollars just for being excessive. Then let’s say the US government didn’t fund one jet and instead built pumped hydro storage. Then fuck it, let’s say nothing worked out the budget got blown and only a fraction of that were built so only 100 stations were built to make it a nice round number.
That’s 2,400 gWh
Idk about you but that is a lot of buffer to make any renewable much more stable. It’s actually enough buffer to power the entire country for a few hours and ideally bridge most of the night demand. For more than three times over budget and for the price of one jet for the US military.
It’s also worth noting this helps all power generation not just renewables. All power plants prefer to be kept at their most efficient output and not turn off or cool off at night while demand is low. We really just need to have a buffer for when solar isn’t active but people are in the early mornings and late evenings.
You’re not being pedantic, you’re just misunderstanding. Pumped hydro storage is not a dam, it’s not a power source, it is a power storage system. You can use pumped hydro at dams but basically anywhere you can move weight up high and use gravity to recoup that is a form of storage. It is one of the most efficient ways to store electrical energy with electric pumps and turbines. The point of a dam has been to collect water that is deposited there via rain and use that to create power.
So, back to our initial problem: chemical storage (batteries) is expensive, environmentally dubious, problematic in many aspects and inefficient, chemical conversion (e.g. hydrolysis) is wasteful/inefficient, etc. So, no, we have no good answer to that.
80% of this is just flat wrong. Chemical storage are not expensive at scale, enviromentally safe, not really problematic, and so outrageously efficient basically nothing comes close. Hydrolysis is more of a chemical reaction in organics and creating green hydrogen is done through electrolysis. It’s not wasteful or inefficient IF all of the power was surplus you had to get rid of because solar does that a lot. By your own statement solar panels are wasteful and inefficient because they only have efficiencies of what 22%?
There is no upstream, you’re thinking it’s a dam but you don’t dam up a stream. You have two containers at different elevations to store potential energy.
You’re conflating a lot of things in this second paragraph. The world can generate enough solar for the entire planet off an area the size of new mexico. LA can power itself off just covering parking lots toe power itself. Then there’s nuclear, wind, tidal… All of these need a buffer because they struggle with either inconsistent production or inconsistent demand. Pumped hydro’s only purpose is to be that buffer. When you’re making lots of electricity you move mass up and when you’re needing more than you can produce you move mass down.
The US can power itself for the next 100 year off waste nuclear weapons alone… but nuclear wants to sit at a flat load. Because of this, you’d need brownouts to shed demand. Pumped hydro means you can run more nuclear and generate more electricity than the grid needs at night or whatever and pump water up a tube to another container.
Basically, the reason we use natural gas to generate power is because it is cheaper than anything and can be stopped/started with much less fuss. LNG tanks are pretty cheap, it comes from the ground at a determined rate… it’s super convenient.
But a LiFePo battery system with inverters and solar is enough to power households if done efficiently for less than $50,000. The price gets lower every year and eventually people will be able to opt out of the grid entirely.
The amount of (potential) energy you can store is a function of the volume of the above container, isn’t it?
No. The potential energy is determined by elevation difference and mass.
Then, could you estimate the amount of water this container would need to be able to retain in a scenario where the grid relies primarily on intermittent energy sources?
That depends on each individual site of pumped hydro. Obviously a site with a 1000m drop will need less water in containment but enough to fill the pipes.
Then, could you estimate the amount of water this container would need to be able to retain in a scenario where the grid relies primarily on intermittent energy sources?
Yes
And can you propose an engineering solution to contain this much amount of water? I already did in my first comment you apparently didn’t read.
It’s not a reinvented dam because dams can only be built where there is a gorge and a drop. For instance you can’t really dam the Mississippi. You also can’t dam mostly every mountain but you can build a container on a mountain and fill it with any mass.
I don’t agree nor disagree with the rest of what you say, I just can’t get beyond the “energy storage is a solved problem” point yet.
It’s hard to agree or disagree on anything if you think potential energy is a dam. Is a truck with water in it just a dam that turns water mass into thermal energy with it’s brakes to you?
I really don’t understand the obsession here in comparing energy storage to energy production.
Do damns produce electricity with the sun? No. Do they produce electricity with the wind? No. They produce electricity via the rain.
The storage of electricity doesn’t have to meet energy consumption because that is what solar/wind/nuclear is for. The point of the storage is to form a buffer.
The first comment I posted shows how if you had 100 the size of the bath county plant you could run the entire US for hours. In just 100 of them. For the cost of the F35 it could be 300 or more but I am accounting for nothing but problems.
From the perspectives of the grid operator, renewables represent risk that destabilizes power delivery. Although weather forecasts are steadily improving and provide more leeway to prepare for sudden changes in the power supplies, the degree to which grid operators can turn on alternative power sources or alert customers to adjust their power demand is limited. In a truly “fossil fuel-free” energy system that relies exclusively on various renewable energy sources, the only viable means of addressing intermittency is to deploy energy storage.
Your source even agrees with me.
The absolute biggest problem with pumped hydro is that it costs a lot of money. Like, it makes nuclear look cheap.
Once paired and optimized for cost, the model returned 11,769 sites in the contiguous United States, as well as an additional 3,077 sites in Alaska, Hawaii, and Puerto Rico, where closed-loop PSH technology can be best deployed in the future. energy.gov/…/wpto-studies-find-big-opportunities-…
What’s 24gWh*11769?
It is a solved problem. The solution is just extremely difficult and expensive.
I don’t want to argue about semantics. If the solution is too costly to be implemented, then it’s not a solution. I don’t think there’s more to be said here.
Yes you do. That’s been your argument this entire time. You kicked around all this time till now saying really weird things like how batteries are inefficient or that green hydrogen is from hydrolysis but then tell me what your point is all along when your point has been wrong from the start.
I proposed using 1.7 trillion dollars in funding in my first comment and now you’re arguing that I wasn’t discussing cost from the start? Is 1.7 trillion dollars not costly to you? Is the project being two times over budget not costly? Is it further not costly that even being twice over budget nearly half are completed? Now is the time you pearl clutch about cost?
You don’t engage in pedantry, you engage in belligerence.
