Since I vanwpaugh was a boondoggle that didn't produce power, they shut it down. Now molten salts can also transfer great amounts of heat safely in a nuclear reactor Terra watts more energy, since it is 24/7,obviosly takes thousands of times less space with attendant reduction of waste, they still haven't decommissioned Ivanapaugh,never produced one watt of useful power.

Did you consider total cost of maintenance? That solar planet outside Las Vegas was $1B failure kzfaq.info/get/bejne/pc-Ahtxjx7G-m3k.html

You’re right. The solar water towers aren’t as efficient with energy production as originally thought. And lots of cost towards Maintanance of constantly rotating mirrors.

Instant fried chicken

@@cycleoflife7331 exactly lol

birds don't get fried. that's a myth. if you actually watch the video, the focal point is a meter infron of the mirrors. and you can't just instantly fry anything with a mirror.

@@cycleoflife7331 hahahahah🤣

Is the focal point the radius?

@@koendos3 No you get a focal point when using a circular parabolic mirror. These are linear parabolic mirrors, so the light is not concentrated in a point but a line.

@@koendos3 no, the focal point of a parabola is opposite from the directorix line. Focal point is where all parallel, incident rays (from the sun in this case) are directed to. This applies to a parabolic curve in 2d (x and y only) space. Since the solar arrays are parabolic troughs in 3-d space ( x, y, and z), all those infinite focal points line up to form a focal line. System efficiency depends on that line having a very narrow (narrowest possible in practice) width to minimize energy lost to reflection.

Also, those parabolic troughs are 4-segment arrays composed of 2 inner parabolic segments and 2 outer ones. They are of course symmetric for max solar capture because they are computer- steered to point optimally toward the sun.

@@nicklockard Just curious, how efficient are those compared to current energy demands and the land it uses?

@Gary Tompkins: Nice! That is sometimes referred to as "passive" solar in my experience. It is commonplace, in areas such as Taiwan, to observe water storage tanks on roofs with similar goals in mind! However, it is prevalent to utilize on demand water heaters in such areas for showers and such, so the water storage tanks on roof tops are more to provide free pre-heating, lower operating costs, and as an added benefit: better water pressure due to gravity's effects! That type of attention to detail can be done everywhere and while the energy wins are not jaw dropping, "everything counts in large amounts" small gains add up over time!

Ha! Love the DM reference.

@@grey5626 " It tracked the sun with parabolic mirrors. "

@@grey5626 no, it is active solar, passive solar is things that don't use tracking systems or need to be messed with after installation like south facing windows, and awnings that are long enough to completely block the noonday sun in the summer, but are short enough to let it in during the winter.

Did it use true parabolic mirrors or cylindrical parabolic mirrors? The latter would be a lot cheaper. Did it use metallic mirrors? Again, a lot cheaper.

Fusion power is becoming more relevant because of advances in science

Need to stop the unnecesarry friction between countries n start working together.. why spend trillions of dollars on "defense" program???

A thorium reactor would also be much more expensive and come way too late to the game. We need to decarbonize energy production today, not in 10+ years with experimental never tested in real production reactors. They would come too late and be too uncertain.

@@jomsies Nuclear energy is sustainable, especially if we use all of the uranium from our nuclear warheads. We have enough uranium reserves to power our entire species for 200 years with nuclear fission without the need to mine anymore, and by that time we would have nuclear fusion to swap over to. Fusion is the future, but we need to convert to gen 4 nuclear reactors now, as well as using other sustainable energy sources like wind, hydroelectric, and solar where it's applicable.

@@lilithva9111 people say nuclear energy isn't "sustainable" but it is close to it. When we run out of uranium as you say something better should be available.

This was great! Thank you.

Amazing there are even Moon powered ovens in use today! Not large scale, though interesting and I do wondering about what a scaled up utility system can absorb from the Moon light?

Photovoltaic cells are usually somewhat heat sensative, so you need to cool the cells, and seperate the infra red light from the rest(ideally using a reflective filter that points at a concentrated solar thermal genorator) since lower frequencies aren't useful for most photovoltaic cells and still produce heat.

Would be awesome if the price point of high temp PV cells came down in price. Is interesting seeing where people have placed heat exchangers on the back of solar panels to use that energy for water or radiant heating.

Also, photovoltaics might be better for small scale, roof top projects, but where there's land available maybe the heat variant is better? Either way, they can coexist

But they have temprature limitation. Can they go to 1000s° and store energy?

you could build this mirror in every desert, it would still never be enough energy, and i don't even mention all the rare minerals we need

Solar tower power plants can have benefits for plants and animals there. Under the mirrors, evaporation is reduced. That means plants have more water available to grow and more plants mean more food for animals. Deserts usually mean to much sun and too little water, so those mirrors remove the liminting factor for plant growth. Mirrors consist mainly of aluminium and glass, so they are constructed from the most abundant elements on the planet. We have more than enough of the necessary materials to cover all deserts with those kind of plants, and those would provide more energy than the world currently needs. We wouldn't even need every desert. And the bigger we build them, the cheaper and more efficient storage we can have because of the square-cube law. Storing the heat with molten salt can allow electricity production 24/7 without needing fossil fuels, but unfortunately those power plants right now are only built with no storage or only a very small storage tank. The storage is not as efficient as lithium-ion, but up to 100 times cheaper.

@@MattAngiono nuclear energy will always be more environmentally friendly than renewables will ever be.

You don't know much now, this is just nonsensical corporate propaganda.

With solar energy possibly causing MORE drivers of climate change and CO2 emissions, I'll take a hard pass.

@@michaelverdouw9551 sort of... it requires A LOT of caveats... The waste from nuclear is FAR worse so it must be managed appropriately, and that is not the case for many current plants. Constant maintenence is required to keep the waste from leaking into the environment, which takes energy and humans. Only when the waste is permanently stored without the need for additional energy and effort is your statement true. Right now, if civilization fails, we will unfortunately end up with a toxic earth. The risks of this can't be understated. Once we can completely rule out the problem of waste, and deal with what is currently requiring maintenence, then I would agree with your statement. We should have a much larger effort to deal with these issues, so if the power goes out, there's no catastrophe. All development of new nuclear would certainly need to mitigate these risks of waste entirely, but that's certainly not the cheapest, nor the quickest way to satisfy our energy needs. However, I agree it should be considered for the long term, assuming we take this all into account.

These parabolic troughs make a lot more sense than the big reflective CSR systems. For a start they don't kill as many birds.

More important to learn to think critically, analyze total costs and not just subsidized ideas while ignoring risks of failure

Storage solutions can also be costly to maintain, not economically viable kzfaq.info/get/bejne/pc-Ahtxjx7G-m3k.html

But it's cheaper than solar cells. Into a price comes down on the solar cells.

@@dueymiller617 The price has come down on solar cells, they are now cheaper. Much cheaper, as in substantially cheaper per unit energy even when you factor in the lifetime cost of batteries for storage(roughly half the price if you have enough LiFePO4 batteries to back up power for 24 hours).

For electricity generation, I totally agree. Solar PV (+ battery storage) is clearly the better option. But there's still one use case for solar thermal plants: Process heat; e.g. for the chemical industry, for hydrogen production (via the sulfur-iodine cycle), for the steel + cement industry, or for seawater desalination. Maybe that'll make sense if they manage to lower the costs (by automating the construction + maintenance of solar tower facilities). Another great source of process heat is nuclear - with a special focus on high-temperature reactors and SMRs.

Regarding the other contra arguments (besides costs): As far as I know, those solar towers are only built in the desert. There you have plenty of space available. Land usage is a point if it means the destruction of ecosystems. But the desert is just a huge area of sand (with only a minimum of vegetation + fauna). So it shouldn't matter if we build things on top of this sand. Frying birds? In the desert, there aren't many birds. Maybe some few vultures, but that's it. And consider that we would only use a small portion of the desert for solar (no matter if PV or CSP), maybe 5-10%. That means that still 90-95% of the desert area would stay untouched.

These mirrors and the heat they generate is the reason there's a drought. The monsoon that used to come from Nevada and Arizona storm turn back and away from California. The High Pressure as Weather Casters call it : keep the storms going up to Canada 🇨🇦 with the occasional drop to the Bay area. This is and I hope an unintentional Weather Modification

Nuclear power is smaller produces more power all the time with less injury and wastes, nuclear fuel is 70,000,000 times as energy dense as diesel which is of course hundreds of times more energy dense than solar or wind.

Also not discussed is the amount of maintenance and material needed to keep the mirrors clean. Efficiency drops quickly with dust and dirt settling on them. It takes water....lots and lots of water. Something not exactly abundant in dry sunny climates.

These negative traits can be fixed and are not permanent. If there’s any trait that is worth mentioning, it’s those that are inherent in the design.

And pls reply to this comment. We need real debate and discussion.

CSP LCOE usually is around 110-140 $/MWh, for comparison this is around 30-45 $/MWh for a similarly sized large scale pv plant, 50$/MWh for onshore wind, 70-100$/MWh for offshore wind, 45-60$/MWh for coal plants (though this price is ever increasing due to taxes, environmental demands, coal cost, ...), gas 70-90/100 $/MWh. Hydro is difficult since it depends a lot on the scale etc. but the larger scales hydro usually is around 20-35$/MWh. Nuclear again is a difficult one. Old nuclear was around 25-35$/MWh, but new ones tend to be much more expensive. Recent LCOE numbers put it between 100-180$/MWh, though 60-70$/MWh might be more correct.

@@vishaljoy6802 You did not just referenced Planet of the humans. That is one of the most disgracefull documentaries out there currently. It uses old outdated information and images, based on based on a subjective personal experience and often if not misinforming at least misleading its audience. Even if they brought it out around 2015 it would be barely acceptable, releasing it in 2020 with no new information since 2014 or so is just unacceptable, especially since renewables progressed massively between 2015 and 2020. One of their experts that was filmed being very sceptical even before they released it had change his opinion to mildly or even very optimistic. Specifically to the solar part: 1) they said solar panels were around 10% efficient and around 10 years of operating. The 10% was around 10-15 years ago true, currently it is around 19-20% on average. And the operating time was just bullocks, solar panels are aimed at an operational lifetime of around 25-30 years, they could even go longer than that, but at that point their output has been reduced beyond acceptable levels (60-70% of their original capacity) and replacing it with newer more efficient panels while recycling the old ones is a better option. 2) they showed a desolate area left behind after a solar farm was removed. One small problem with that. That farm was in a renovation stage. The old panels that had been there for decades and reached end of life were removed before they filmed and new more efficient panels were installed after they filmed at that location, so that desolate place doesn't even exist. 3) they also talked about an CSP in Nevada or California (I forgot where it was) and told about how it needed natural gas in the morning to spin it up. One small problem with that is that the plant was one of the first CSP plants, modern ones don't use natural gas at any point of their operation. Moreover what they don't mention is that even this first inefficient CSP plant reduced natural gas usage by more than 65% compared to a regular natural gas powerplant. I can keep naming things about the documentary where they were misleading, or used too old information etc. but then I am going on for the next hour or more, so I'll just stick with this. There were some good points, however these were overshadowed by the bad ones. Moreover these good points didn't offer nothing new at all. The main message of the documentary of focusing more on saving energy and resources by for example limiting usage etc. has been a core pillar of the green movement for decades. The next thing is probably a bit more controversial. At the end they talk about overpopulation and that our population should shrink and that mostly the undeveloped world is the problem (at least in terms of growth), that is not a problem at all. We don't use too many resources due to overpopulation, we use too many resources due to the way we manage them and the large amount of resources that we waste. The earth can support several times the current population if we'd much better manage the resources. However I can understand if people were to disagree on this last point.

The weather there would destroy it.

you'd have said the same thing about offshore wind 20 years ago though and look how once the industry was established, and reached some scale the prices plummeted. nuclear is not cheap either

@@mralistair737 yes but the problem of the energy storage remains true. Here in Europe the countries invested hundreds of billions of euro in photovoltaic and offshore wind.
