Huh... Nuclear is a great source.

[@braveecologic2030]

Curveball slightly oddball, why? It seems like a point is being made but the relevance to the actual picture is not quite connected. Personally I have spent decades developing next generation renewable energy technologies that I am only now in the process of implementing with assistance from Green Assist and the European Commission: CINEA. The reason I developed my technologies is because until nuclear means Fusion, I really don't like the downsides. I did also develop my technologies so that they will assist central fusion power production with augmented, fully renewables mitigated energy storage systems for intraday, interday low loss storage and seasonal lossless storage distributed comprehensive energy security systems. So I have some handle on the situation that leads me to make my suggestion that fissile nuclear is really not the way to go. It is one of the many technologies that got us to here and now we really must get ourselves to where we really must be. That isn't fission or fossil.

[@braveecologic2030]

@@dankomancer It is, if it isn't fissile.

@@braveecologic2030 It's the safest energy out there. The waste is sealed in concrete that can withstand tanks and then shoved into a mountain. Only downside is the cost. It's massive up-front money for a long-term payoff. Fossil fuels you can just slap a turbine down and then purchase fuel. Also, we are still far from producing anything from fusion.

Each country, and even region will be different of course. Japan for example can build nuclear power plants (in japan) for nearly 1/5th the costs of those in Europe largely because they have the experience, the personnel, and a bureaucracy that simply allows for it. Once the EU has a few new ones under its belt, costs should come down.

Not trying to strip the kids of their achievement but you are giving them a bit more credit than they probably deserve. I won a science fair project contest back in the before times (1990s) with a magnetic train. The idea already existed I just built my own very crude copy of that.

Excellent small scale power bank, actually. Enough to charge pretty much any handheld device at least, indefinitely, and all you have to do to adjust the output is add a heavier weight, that you simply reset when you need to.

While mechanical batteries offer an intriguing alternative for energy storage, their practicality is limited by inefficiencies in energy conversion and the large physical infrastructure required. Additionally, compared to chemical batteries, mechanical systems often face challenges in scalability and maintenance, making them less feasible for widespread use in modern energy grids.

A water tower would work better, and companies are doing that. The thing is there are so many companies working on energy storage as it is the future. So many technologies vying for it, and there are many chemical or thermal batteries that work better for cheaper. Redox for instance looks great. It has to be cheap and scalable. So a liquid chemical battery is great since making a container larger is easier than building a bigger tower. Since a container benefits from square cubed adding one foot equals way more volume. I'm all for renewables. Just not with this when there are better solutions. Redox tech looks great.

[@MrBrannfjell]

Sounds like a very good idea actually, why not have a gondola lift system? A platform on top of a mountain to store blocks, send blocks down to the bottom of the mountain to generate energy, send it back up to store energy. I guess is that the limitation is weight or size constraint due to it going on a very long cable. But with energized rail tracks, the "train" itself could just be a heavy engine moving up and down based on voltage in the track.

[@lpdirv]

Pumped hydro seems like a much better idea.

[@David-il6hn]

Thermal storage using deep cavens. Allow water to fall down into cavens, get heated up from the earth's fire and then return as steam. Hydro turbines used on way down and steam turbine on way up. It may also be possible to harness the air pressure as the water fills the cavern forcing the air up a pipe.

[@JarofMayonaise]

I'm no scientist but this sounds kind of feasible. The only problem I see with this idea is the creation of a cavity that far down to where the earth would boil water. Roughly 7.5 miles down and at a temp of 350ish degrees Fahrenheit is the deepest hole ever dug by man (soviets) so it's possible to reach far enough, however their experiment ended because their drill bit(s) melted from the heat. You could try to find a natural cavity to hold the water but you would never know if it was sealed off enough to retain any water to boil back up. This would mean you would need to create a cavity, of what size I do not know, without the machines doing the digging melting from the heat. You would have to control the pressure with pipes and whatnot so you don't create a blowout with a natural cavity. Other than that, solid idea.

Remember, pressure can also be used and a more recent development is using sand as a storage battery. What I am really trying to say is let's use that free and permanent source of energy. Iceland, Norway and Sweden are experts. They use the earth's heat for district heating systems so why are others not doing the same. Heating our properties takes up so much energy. Heat pumps may be a start but there is plenty of room for improvement. Using the heat and pressure from the earth which is a natural storage medium together with modern science could certainly be a way forward.

They were designed to automatically stop the reaction if it ever got out of control (I have no idea how this works, but to my understanding this is a very common thing in modern reactors) and just go inert, already buried and shielded.

From my nomadic perspective, solar energy is a game-changer, providing reliable and cost-efficient power without the burden of electricity bills. However, applying solar and batteries to large on-grid houses seems less effective due to the issue of over-consumerism. In contrast, embracing solar energy for nomadic lifestyles promotes sustainability and independence from the grid. While I support the idea of combining solar panels and storage batteries, it may be more prudent to reduce overall energy consumption and reassess our dependence on large-scale housing to realize a more eco-conscious future.

We haven’t even begun to scratch the surface with the potential (pun intended) of pumped hydro. It’s one of the most undervalued approaches with virtually the greatest potential. There are so many ways to solve the “issues” with it that simply aren’t being considered, and the places it can be used are far more diverse than virtually anyone seems to realize. Along with that, I would say something simple like CAES using old mines as pressure vessels would be able to handle short term demand much better than any of the other mechanical systems discussed here - the efficiency is reduced, but that isn’t as important for short term use. Chemical batteries can also fill that role - but they are a bad approach for primary energy storage (too expensive and too energetic/dangerous).

The rest of the time it's like everything else, we can make money and gain mutual benefits from social connection but can survive still and thrive somewhat if the extra social essentials are cut off. Our energy security buys us all the time we need to rejig if the social network gets interrupted and we'll need a minute to figure out the next way we socially reconnect if the system goes down and we need to make a new one.

[@loganfowler7417]

It's a fair point, but it wouldn't be outrageous at all for these machines to use power electronics to be a buffer between the actual generator they are turning and the rest of the grid. Most large windmills already employ a DFIG for the exact purpose. Rotor synchronization isn't necessary in these kinds of machines since the grid is not directly AC coupled to the generator. The generator produces AC which is converted to DC and then inverters produce grid-following AC power without the need for mechanical synchronization.

[@carlos-dt2tz]

I didn't know that. The design us different from conventional and nuclear turbines which have to be synchronised to the grid. They tend to follow the grid to prevent the grid feeding back against the power stations turbo generators causing them to speed up causing automatic tripping of the plant which would take it off from supplying.

These water towers are extremely common in America (I don't know where you're from. You may already know that.) Also, the concept of storing energy with mechanical batteries is not as much about efficiency, but more about having an overabundance of extra energy, and still having energy on demand when the wind isn't blowing your windmills, and clouds are blocking your photo-electric cells.

@@quellenathanar The water towers you are talking about store water. They are not meant to store energy. And what i just told you is that you cannot use them for energy storage, becuase the amount of energy they can store is very, very, very, very tiny. 1 cubic meter for twenty minutes laptop time. Now measure one of those towers for volume and divide by that number.... You would need a water storage tank the size of a house on top of the actual house if you wanted to make so much as a dent. And THEN you would have to build a cistern below the house to store that water while discharging your gravity battery, otherwise all the water given off by both your house and all the other houses would flood your street and overwhelm your sewage system.

Hydrogen has many flaws, it is at best 25-30% efficient in a Power to power configuration. H2 is very low density energy (in volume), to contain big amounts of it requires a lot of space, expensive tanks that limit the loss due to it's small size and a lot of energy. Even worse, current tecnologies are way too expensive because of the use Platinum or rare earths catalists, which also require a lot of mining.

[@paulfreefall]

At 43:40 mins he demonstrates by how much the volume or air in the lab would refrigerate down to a liquid - down to the size of the fridge (700 times less volume). I was quite surprised at how much liquid there would be, or how much mass air has! I think this is a good demonstration of how much air weighs, and why moving through air causes so much drag. When James May took the Veyron up to 270 mph he said at that speed the effect of drag is like driving through a fruit cake. Which is also another good analogy.

[@brianmulholland2467]

I'm deeply skeptical of the solutions in this video to scale. Wind/solar have multiple flaws, but the lack of dependability is the biggest. I think people don't grasp the sheer scale of energy storage we're going to need if W/S are really going to be the backbone of our energy future. Bill Gates gave an example at a TED Talk about 15 years ago where he said that if you took every single battery humanity has ever constructed, imagined it had the full 100% capacity it had when it was brand new, and dedicated it to backing up the world's energy grid based on current (15 years ago) consumption, you'd get 10 minutes of energy backup. And we need storage for not just overnight, but weeks, and potentially MONTHS because even if W/S is producing SOME energy, it's likely producing LESS than it's ideal, and can underproduce for months of overcast winters, or lower wind trends. It isn't just compensating for when it's producing ZERO power. It's why Gates was/is skeptical of W/S, and I am too. We're going to need a wonder-of-the-world caliber energy storage solution next to EVERY population center in the world. Probably MULTIPLES. It's why we really need to stop acting like W/S are going to be the backbone of our energy future. They're more likely to end up as supplementary sources. Leaving storage and transmission and grid enhancement costs out of the LCOE metric distorts economic policy planning in favor W/S. But these are NOT separate problems. These are inherent costs OF W/S. Other energy solutions don't have these problems. I think enhanced geothermal and fission ought to be higher on our list. Geothermal is a great way to take advantage of the drilling expertise currently developed by fracking companies. Fission is mainly expensive because of the political/legal environment that has been crushing it with extra costs. These produce steady base-load power. These should be the backbone of a low-carbon energy mix until we arrive at commercially viable fusion (likely after I'm dead). The entire US pacific coast is a treasure trove of geothermal potential. Instead of dumping all their money into unreliable W/S, they should be drilling geothermal wells.

[@MarWeyog]

This was great! thanks for the documentary. In that last liquid air plant, though, I have to admit that the physics teacher in me cringed when they talked about capturing and storing the "cold" when they really just mean low-temperature substances. :)

[@h.e.hazelhorst9838]

Cost for storage (depending on the type) should be included in the cost of electricity from wind and solar. You could easily make a distinction between the three types of storage: stabilising the grid, daily fluctuations and seasonal fluctuations. At the other end of the spectrum, cost for the negative impact on climate and environment must be included into the price of fossil energy. Then, an equal playing field is established.

[@AlbertMark-nb9zo]

At the present time, why should it when the grid can actually take it all except in special circumstances and just replaces conventional power. Around half of power generated is base power, the other is variable and diurnal.

[@TheTerryscotttaylor]

This is not being reported in a manner that's meant for people to analyze it easily. That's because the push for solar and wind is a political initiative. It's not about efficiency. Modern Nuclear is so much better than any of this that you would have a hard time graphing them all together and even seeing these other options. Best power generation: 1) nuclear by a large margin 2)burning coal/gas 3)WAAAAAAAAAAYYYYYY less efficient options If you care about the environment, and you're realistic enough to handle that most are not passionate enough to never use more than one sheet of toilet paper per bathroom trip (or any other use reductions measures that reduce their comfort) then you should be 100% behind increasing use of nuclear. Period.

Let's build nuclear or thermonuclear reactors and produce energy when needed - no large storage required. Gravity store is economic with water but not with concrete blocks. I recommend thunderf00t video debunking this idea.

[@jeffreyryan7671]

The only PRACTICAL way out is building new fail-safe nuclear plants. China is now running a Thorium plant that they got from us in the late 50's to early '60's. Thorium reactors are immune from power loss, like what happened at Fukushima. They also require no operators to shut themselves down in the case of overheating. Gravity shuts them down, and gravity is always there. The place that was pumping water up to a lake, then using its reverse flow for power, took 10 YEARS to build. If we put that time into many nuclear plants that require no mining to power them, there would be no need for these energy storage units. Not that I'm against them. We have huge stores of radioactive "waste" that can run the new plants, already pre-mined. I emphasize no mining, because it produces huge amounts of CO2. Also, we are taking old nuke warheads from our own stock, as well as buying THOUSANDS of Russian warheads,(This is already been happening, we have purchased 26,000 from the commies already) all which is ready for minimum processing before use. As compared to mining, for starting up MANY plants. I just can't believe Nuke power is not even being considered, when it is safer than solar when you factor in the mining for elements that are required to make solar possible. As well as the very carcinogenic chemicals needed to process solar panels. This gets way too complicated to explain quickly here, but the simple way out of our energy problems, as well as the safest, is nuclear. Has been for several decades. With no Fukoshima's or Chernobyl's. So why haven't we been building more NEW safe Nuke plants already? Fear by the uninformed American people. Oh yes, and mostly.... GREEDY OIL COMPANY'S !!!

Now their economy is totaled. Plus, I would not trust them to build a reactor of any type that I would trust. Despite Chernobyl, I would expect them to cut every corner, safety related or not.
