[@ekeretteekpo3004]

I don't understand. What did he do?

[@hk8450]

Efficiency is very important. Such experiments always fail. When there is some cloud, the heated surface will cool down and efficiency will decrease. The idea of producing energy by collecting solar energy to a point is ridiculous. Deterioration in the materials used will render the entire system inoperable. wind dust storm all included in this. and there will be a lot of energy loss.

I've got this mirror concept beat by miles. I built a tracking 600:1 concentrating mirror that makes continuous live steam or drives a retort that is used to make charcoal from wood or petroleum products from waste plastic -- all for around $50 US.

its so crazy to me that half our advanced technology is just boiling water. I love it 😁😁😁😁

Yep just about all power plants are designed to boil water into steam to drive a turbine (most efficient) so fuel source can be either from coal, oil or nuclear & even solar. Only power units that can collect direct power & not use steam are Solar Panels, Wind Turbine, Tidal & Hydro.

You need less heat if you us an evacuated multichambered system that flash boils pure degassed water when sprayed in then passes through a turbine then into a cold chamber where the remaining steam is recondensed if the vacuum reservoir is large enough it operates continuously in a closed loop system for the water.

[@marcelb.7224]

[@CUBETechie]

I think solar thermal energy devices can be also used for Industrial processes which require high temperatures

[@ckeilah]

This is all fine and good for commercial power plants, but for an individual's power needs, solar cells just cannot be beat. They're quiet, SAFE (no hot oil!), relatively cheap, mostly maintenance free, and Just Work® for decades. The new ones are pretty tough, and can be placed even where they might be walked on. Amazing!

[@stevenlarson3316]

Ya, photovoltaic basically won this first round hands down. Concentrated Solar is about twice as expensive as photovoltaic and can really only be used in a large scale setting. The one advantage Concentrated Solar has is power storage in molten salts for power over night. But it's still not enough to compete until we stop using gas and need the storage. There is around 1700 gigawatts of installed photovoltaic capacity in the world and only 7 gigawatts of concentrated solar.

[@BrilliantDesignOnline]

I had no idea the Mylar reflective films degraded so fast. 1.5 years is not very long; I wonder if a sheet of glass or polycarbonate over it would increase its longevity?

[@thibaultjoan8268]

Considering that the main factor seems to be that the film tears off, maybe just gluing it to something rigid

[@FractalNinja]

Putting the dish in a box with plexiglass cover would shield it from wind, hail and debris :D losses should be minimal (better than replacement costs for the reflectors 😅)

[@Humbulla93]

a coating of elemental silver would be best for longevity and reflectivity, it´s also easy to apply, just coat the dish in tollens reagent and spray some glucose solution on it, this deposits a thin layer of silver. that´s how mirrors were made

[@Letsgoback2thefuture]

Innovation with nature is exactly what we need. Nature is already on auto pilot. We just need to modify our tools and tap into that endless source of energy

[@tiagotiagot]

Is there a good reflective material that can be vacuum-formed? I think you could perhaps get a good parabola by sucking on a material thru a circular rim ( but of course, don't suck all the way, or you just get a flat circular hole though; not sure the details, haven't worked with vacuum-forming personally yet). Or maybe it could be done with hot water instead of a a vacuum-forming machine, combining the heat and the weight of the water? I'm not sure how that would affect the final shape; and cooling quickly once you reach the target shape might be tricky perhaps.

[@brusso456]

use insulated underground water tank as a heat bank. if you collect more heat than the tank loses to the environment, no matter the size of the tank, it will eventually reach maximum heat storage.

[@DespaceMan]

The best efficiency for any Solar power device is at the equator, there are places that get sun almost 365 days a year. So these countries at the equator then can collect the energy & export it to northern or southern countries via cable using DC transmission as it's better for distance.

[@unogazzy84]

[@moneymuscles4498]

Sergiy, been watching you for years! Try refraction to focus instead of reflection!

[@DrU387]

Can he use frensel lens for that ?

[@lizard5678]

@@DrU387 I think refraction is more expensive. A mirror can be very thin and cheap and attached to something sturdy and cheap, while large Fresnel lenses made from transparent plastic would have to be molded, an expensive process, which might be OK if it lasted a long time, but plastic degrades in sunlight, though UV absorbers can help, but only so much. Made from glass would resist sunlight but would be expensive and fragile, especially if thin. With mirrors you can use really cheap really thin things with short lives, or more expensive things with really long lives.

[@DrU387]

@@lizard5678 why glass frensel lenses are expensive ,silica and sodium carbonate and other oxides are not that much expense ,what is the concept of expensive from a manifacturing point of veiw what is the technical issues and why such a sustinable way to produce a lot of heat from the sun not generalized in the world especially in the poor areas ,is that a proplem in technology or economics , i don't know it is very mysterious thing to think , glass manifacturing are not that complex and we are talking here about something that you can make it once then we have a sustinable "free" energy for a while.

[@lizard5678]

@@DrU387 Thinking of tempered glass pickle jars at the grocery store, which are pretty cheap, so maybe they would not be that expensive to make. Regular flat glass is floated above molten tin in a molten state, and to get the Fresnel features and indentations into it it would take a similar process to how the threads are made for the lid on the pickle jars. Then the whole thing would have to be tempered/heat treated/held at a certain temperature to relax thermal stresses. Istill feel this would be more expensive and less sturdy than sheet metal bent to a paraboloid shape and a mirror surface polished unto it.

[@lizard5678]

I was also thinking a parabolic trough setup where the mirrors move and the tubes stay stationary near the ground could eliminate heat transfer fluid leaks. Most of the setups in this video require flexible moving high temperature fluid connections, it's much easier to have solid welded ones, but you have to move the mirrors and hold the heat collector steady. One solution is the solar tower setup, mirrors move and tower is steady, but because of the long distances involved, aiming calibrations are more difficult and expensive than with the relatively short distance parabolic trough setups. You could also have Fresnel lenses that are not circular but linear, many parallel prisms that focus the sunrays along a line unto a tube, instead of to a point, and then you would have to move the lenses while keeping the tubes with the heat transfer fluid in them steady. A good heat transfer fluid to consider is NaK, it's dangerous and requires astronaut suits to protect against leaks, but it's fluid at room temperature and can be used up to the boiling point of potassium. Also the tubes should be covered by an evacuated glass tube for no heat conduction, that has a mirror surface, except the mirror is cut away or etched away where the sunlight comes in, say 45 degrees out of 360 degrees, while 315 degrees around is mirrored. The evacuated glass tube might have to rotate to accommodate changes in the main mirror or Fresnel lens positions.

[@dlewis9760]

The toughest part is getting useful energy out this for a private home owner. Your video makes complete sense, but unfortunately the conversion into something useful is the tough part.

[@jamest.5001]

I hvent completely thought it out yet, but seems a completely automated tracker can be built using little more than a solar panel and gear reduction motor. With a reduction low enough to take all day to move the reflector or collector, the solar panels to power the motor when the sun is out to be tracked, a few other parts can keep it going sun or no sun. A similar system to change the angle depending on month. Thr tracker trying to keep the solar panel out of the sun. With another wired in reverse to track th way back north. A microcontroller can easily be programmed to return to the east at night. Ready to start the day long journey in the morning. Possibly use a speed control or dc to dc to lower the voltage as the days get longer, based on the tilt of the system. Set by thevmnth ir week of the year maybe as accurate as the day of year. A simple analog system can be built, using the solar panels to power relays. With limit switches and a two way switch auto trippd to reset at night. It can use tiny solarcells to wirk as sensors. All it needs is power, 12v is plenty!
