Concentrating Solar Thermal

Beyond Zero Emissions intends to transform Australia from a 19th century fossil fuel based economy to a 21st century renewable powered clean tech economy with no carbon emissions. Sharon Shostak met up with some local residents/BZE volunteers who have taken the initiative to build a model to demonstrate a concentrating solar thermal plant, a technology beginning to proliferate in many countries but sadly remiss in Australia.

Hello from Russia! Here, people do not pay attention to renewable energy sources, but mineral oil once completed, or will be prohibitively expensive, and then the public will pay attention to solar energy. You give the opportunity today to understand that the energy of the sun for the future. I am also planning to create its own hub Solar concentrator water heating capacity of 6 kW, but not sure that people will show interest in him. But I will strive to ensure that society has realized the benefits of using solar energy in private houses. Great work is done by you, thanks!

Good work you Aussies. All your points are correct. The only problem is the government, just like here in North America. . . Mark Jacobson at Stanford University has a plan to convert all of NA to Wind, Solar, Hydro and Geothermal. He has determined the cost including new grids required and it all works. His plan would make more jobs and is good for the trade balance. It is beautiful economics.

Why do you respect their efforts? Their efforts are to pursue a failed idea with half-ass amateur nonsense. You respect that, douche? Maybe respect efforts that are scientifically advanced and work and not a damn waste of time and energy.

[@bishankagrawal2948]

Kube Dog exactly that is why I respect their efforts as they still have hope and delivering their time and energy for what they believe..... unlike others who follow the world leaders they them self are aspiring to be a energy leader they spend time energy on what they believe rather spending on what greedy douche believes....I know it will hurt you

[@andrewcavanagh3946]

Thermal solar is a proven technology with multiple working plants around the world. This is a tweak on that and there is a working model like this in Port Augusta.

[@gabrielsierra6890]

There are salts that are already liquid state, like Perchlorate, which is what thermosolar plant use.

Guys, great video. Where would the salt come from originally? Would that be a possible link with desalination plants?

Really good

[@reddoglavrador]

those who know the story of the “father himalaya”, an inventor born in 1868, in order to publicize his invention, decided to participate in the Universal Exhibition of St. Louis, in 1904, presenting there an even more perfect apparatus, which he called the "Pyreliophore" - that is, "I bring the fire from the Sun" - with which he managed to obtain a temperature of 3500 degrees

[@pmodi4851]

how much temperature did you get at the top of the reservoir tower?

[@sietzevandeburgt681]

Well i’m winter or in cloudy conditions over here we have just 10 percent of the light so if we do use these we need 90 percent extra mirrors and we need an extra autoshading electric filter either for every mirror included in your with refelection behind it or at strategic places and sensors to detect rolling in and out clouds at kilometers distance and when the auto shading glas activates we need to turn downward several mirrors and see that it can be used to always work at a hundred percent !!!

[@user-oe2he7hg5y]

Im looking at power plant designs and they release a lot of water as steam. How does your water condenser work so that it is a closed loop without water loss?

[@urgencepc4563]

''So the cool salt goes up the tower'' Ok - HOW? you train them? You sing a song to the salt? How does the salt ''goes up the tower''?

[@markshort265]

Glad someone else has commented on this. I was thinking the exact same thing. Surely it would already require the use of electricty to do this before it's even generated any of its own.

[@astasna]

[@matthewerwin4677]

I built one of these models for real. Crescent Dunes solar energy project. Tonopah, NV. Matches this model pretty closely.

[@MuhammadUmar-et2co]

Can you please guide me on how to build a small working model of this ?

[@robertphillips2142]

This is a very clever idea and a great explanation. However I am not a fan of destroying the countryside with a ton of mirrors or solar panels for that matter. Seems to me that if we looked at the horrible inefficient building methods, corrected those, then less power would be required. Example, homes having their hvac pipe and evaporator coils in the attic. I have never understood why they would take metal pipe, install it through the hot dusty attic which can reach temperatures of 140 degrees+ in the summer. Wrap insulation around them then proceed to pump cold air through them. The thickness of outside walls should be much thicker and the wall studs should stagger between the inside and outside to stop radiant heat transferring into the house. Natural plant barriers constructed to shade outside walls of houses. A lot of a homes power requirements comes from heating and cooling. The retractable overhangs on a house being extended to reduce the sunlight from heating up the house in summer but retracting them in the winter, solar skylights for lighting. All these improvements would reduce a homes power consumption which would reduce emissions. Then nature would not become a sea of solar panels and wind turbines.

[@minecraftartpics2969]

Cool!

[@vaggs75]

Amazing video! How do you insulate it to the point of 1% loss?

[@David-bc4rh]

I think what we need is a working model.

[@harmmeijer6582]

It works but failed: kzbin.info/www/bejne/qGqslX1-g76LapI This may be due to the high operating costs compared to photo-voltaic solar power but could also have been a problem with working out the design, at such a large scale the investments get very high and at some point people will bail.

[@sietzevandeburgt681]

This setup can also be used to make salt water into sweat water at the edge of the desert and he sea and if you pump water through fast enough you have a thick sludge that you pump back to sea since is a way to actually there is much sweat water added by melting ice So lets make australia green again since it is actually using the right amount of water to turn its world back to green land and a forrest in the long run creates extra rain for itself !!!

[@freddielewis2390]

[@pankajdahiwadkar4342]

Which material did you used to transport heat?

[@bluepawn]

Where can we buy that in Switzerland for our houses or balconies ?

[@ejbh3160]

can I make a suggestion... instead of burning the biomass, put it through an anaerobic digester to capture the methane & digestate fertiliser. The methane (CH4) can be stored and put through a fuel cell like a redox cube which uses the Hydrogen atoms to convert directly to electricity and the hot water used in community heating.

[@LAUANTKAYPRODUCTION]

hi,like your work..do you have any idea of how it will cost to set this type to plant on half scale...

Woow, if this works it would be great ! I've been doing some research into alternative energy sources and this idea of storing heat is great :)

[@Kube_Dog]

If this works. Right. But it doesn't. These are couple of dumb shits screwing around with a half-ass idea and looking for attention.

[@andrewcavanagh3946]

There's a working plant in Port Augusta. There are also plenty of working thermal solar plants in multiple locations around the world. They have a higher cost of setup but may produce power at a much lower cost once you take into account the longevity of the plant (which is still an unknown factor...suggestions are the could last at least a century).

[@andrewcavanagh3946]

Solar thermal works on pretty much every scale from small home solar ovens which have heat storage, to commercial solar kitchens that cook at night all the way to full working power stations. en.wikipedia.org/wiki/Solar_thermal_energy There's always the question of cost and investment. At the smaller scale built with cheap materials they're always cost effective.

nice idea! i wonder if salt tank could be underground, this hot salt tank if this could make a difference also to radiating heat from it

[@Jefff72]

How can we make sure birds don't fly to the bright light and get fried? Could you cover the tower just where bird don't see the light or perhaps a sound at a frequency we can't hear? Not sure what frequency birds hear at if that's possible.

[@czarcorey1220]

Tell me if this is stupid: Why not kill 2 birds with one stone and use these as desalination too in dry areas near bodies of salt water, California for example. If you run out of the steam through a turbine then condense it back to water and send it to a secondary treatment plant. The salt should melt and fall down since it is denser and doesn't turn into gas. Instead of having a closed system just have constantly new supplies of water and salt. The only downsides i see are that it is an inefficient way to desalinate water, and you have to deal with brine. But its greatly offsetting the cost of desalination by producing electricity and its not energy intensive like most desal plants. Any major flaws that i am missing???

[@czarcorey1220]

What if you run the steam*

[@andrewcavanagh3946]

You're a clever man. They have one of these in Port Augusta Australia that generates power and desalinates water. They initially thought of using pools to let the salt come out of the brine to sell but gave that up because it wasn't commercial to sell the salt products.

[@czarcorey1220]

I did some research back in 2015 to find something that operated like this but I couldn't find anything. I will research the one you mentioned. Thanks!

[@zurviver_3747]

salt water is corrosive to the equipment, hard to find materals for that purpose but logical thinking, also deserts are the best area for solar(pv, csp) power due to thiner atmosophere maybe norther Africa (desert +ocean)

[@whotoinfinity]

Seems the return line, from the steam turbine, would provide enough heat to run a industrial sized stirling gen/set too!

[@DrJustinable]

i was wondering if you could also use salt water (seeing as there is an abundance of it as opposed to fresh water) to burn off the water for steam engine and reuse the salt

[@GiuseppeGibilmanno]

there is one of this here near Etna

[@sapoty]

It is Nitrate salt used in agriculture. The salt is continuously recycled. So no extra is required . Sea salt is not the right kind of salt.

[@oldreprobate2748]

This would enhance sea water distillation plants making them more energy and financially viable.

[@adelaidehulahoopers9286]

the insulated salt stays hot...until it loses heat via the circulating water. How long does the heat last?

[@amirrahiminia2556]

Hi Echonetdaily! Which salt do you propose to be used by this system and why the choice is 200 degree Celsius?

[@robertweekley5926]

The 200° Temperature, as he said, was the "Melting Point" of the "Salt", so, it shouldn't take much research time to identify the specific Salt, be it Sodium Chloride, Potassium Chloride, or another! So, 200° was not "Chosen" for any other Reason, than that is the Minimum Temperature to Liquify the Salt, so it can be Pumped into the Tower, to the Concentrator Head, and then uses the Sun, to bring it up to 600°! At 600°, you can easily pull out as much energy as it will deliver, and not cool below 200°, or the System will effectively be as if it was "ICED UP!" But, you could easily pull it down to 300° and keep it in Circulation! Also, this would "Only be drawing down the temperature of the Liquid Salt, after Sunset, overnight, and before Sunrise! Using a High Mountain as a Backdrop, in the North Side, in the Northern Hemisphere, (Flipping that around, so the High Mountain is to the South, in the Southern Hemisphere), would allow an extra Period of time, to Send Concentrated Sunlight to the Towers Receiver, from 30 Minutes, to even over an Hour! It would also start reheating it an equal earlier time, in the Morning!

[@thestonemaster81]

should have put water in can and see it boil or a thermostat showing the heat in your model. . Great job with the rest of your model

[@yulopthegreat]

so the salt is melt before or after then pump up to the tower?Not understand..

[@immanueluykhilam8278]

Hi guys, I would like to ask for advice with regards to making an actual small and portable version of the CSP. Maybe in a form of what typical generators at home look like size-wise. This would greatly benefit areas that are considered off-grid. I'm not sure where to start, because the math and concept seems too complex to start with when adjusting it to a smaller version, I would appreciate any advice. Thank you so much!

The panels in this model and the real full-size versions are just mirrors that track the sun, cheaper per sq m than solar panels. But this doesn't work at small scales below an acre or so. The tower is also costly, as are the parts to pump the salt without them corroding, but these are all challenges that have been solved.

Nice video Australia should be at the forefront of all these Renewable Technologies, with more political long term planning and a stronger emphasis on science they could have developed the know how and industry to be world leaders in these arts. I understand that all houses built in Israel for the past 40-50 years have to have a Solar Thermal Collector to heat water by Law - correct me if I am wrong. With the evacuated tube heaters that have been around now for about 30 year's that can heat water even through a layer of Snow I feel most countries that can should be implementing a similar policy.
