A reflective parabolic dish is one of the cheapest ways to concentrate solar power and put it to great use. This method is widely used in many applications.
The video demonstartion is only to show you how powerful the setup is, and it produces insane amount of heat. This heat can be utilized to achieve so many things.
Disclaimer:
The solar reflective dish can cause serious burns if not handled with care.

The concept was inspired by Dan Rohas from Green Power science.

Hello my friend.
I saw another interesting idea. A very powerful parabolic solar concentrator. I like these kinds of interesting ideas. I watched with curiosity. Congratulations.
Stay healthy and happy. Big greetings. A warm hug...
Thanks Mehmet. Thanks for watching and sharing you views. It means a lot to me. Stay well. Greetings!
Very informative and very entertaining to watch. thank you Video Eppo
Glad you enjoyed it!
Number 3, would work extremely well. If you get 800C you just need to engineer it correctly and find a battery. But since this is about experimentation look into building a liquid battery using sodium.
Considering the rising price if cooking gas in my country. This certainly I'd install for cooking. Thanks
I read in your comments that you've dismantled the dish, and also recommended copper coils. I finally obtained for myself a 6 ft satellite dish, but, the dish is made of a somewhat fine metal mesh material, and I'm not sure how I'm going to go about making it so the surface is smooth for applying aluminum or mylar. I would assume that I'd want to minimize the diffusing of the rays to be as little as possible. Also, thinking about how a combination of using the dish to collect the rays and distribute them to a smaller area of copper can save on the need for a lot of copper while still harvesting the same amount of solar thermal energy. Either way, this reminds me of when I learned about how they were planning to use parabolic solar collectors to pump water from the Nile river to arid parts of the land to make it more suited for agriculture. This was in the early 1900s, I believe, before fossil fuels became much more readily available.
You can use tiny mirrors if it works for you...or a combo of mylar and mirrors could also work. And many thanks for taking time to comment
Very intelligent man
Thank you Sir!
Thanks for your reply! Can you just do an test with 10L of water (for bathing). And raise it to like 45 degrees Celsius from ambient. Plz note time for the same. I wish to build one but with 2 small dishes
I have already dismantled this unit. Actually there is no place to keep it as the house owner is objecting. But raising the temperature of water to 45 deg Celsius wouldn't be a problem even for a small dish. Actually, for that kind of temperature you can simply use copper coils and paint them in black and let water flow through it. make sure its exposed to bright sunlight and it should be good enough.
The copper coils can be easily found in shops where you find Air-conditioner spares
@@VIDEOEPPO Thabks! I have a copper coil water heater (check my channel video). I want to experiment this with the dish!
The only way to use this for cooking and baking is to stack a pizza firebox designed for gas stove. You just need to place a black brick plate and a ceramic glass to trap the heat inside. This is how you can cook bread, pizza and meats inside a solar pizza oven 12 inch.
How to calculate the temperature at the focal point of any parabolic mirror...
What are the parameter needed...
we can simply point a laser thermometer and check it...
@@VIDEOEPPO do we have any formula.... Please tell me...
@@arunbuddy4656 me too. I would like to know a formula to calculate the temperature of focus point vs diameter of parabola.
i made it exactly the way you made it and the dish dimensions are also same . And the part you dont know is , I melt aluminium in just 14 minuts, I achived about 921 degree celcious tempreture .
wow!...can you share the link of the video here...I really want to improve this!
What a performance you are quite right but still it is very small result if you are interested we can enhance is many time more to produce unlimited energy
How about solar water heater? It will great just to fix this on top of a roof and we can get free hot water all day
True. I could be useful in cold places. But the climate in my region is mostly hot ,So I didn't think of that option
I made plastic recycling from sun check my youtube
Sir, Its full applications can be seen at Saibaba temple , Shirdi in Maharastra. Also at Balaji temple. The total meal is cooke with this concentrator.
Bro mast content tha
Thanks Bro
was starving for u r video , finally after a long time
Yeah ..This one took some time to source the materials
@@VIDEOEPPO True sir , you have made great effort on it , in Sheeradi Sai baba temple they uses the same principle with thousands of mirrors moving mechanically focused into a point in a modified water tank and the water is heated to stream , and the hot stream is used to cook the free food there , i was surprised to here this , as they have made a great effort on sustainability
@@VIDEOEPPO czcams.com/video/kv9RZXGDHE4/video.html
@@gkrishna9841 wow, thats new. I've been to sreedi 4 times. This should be a new addition. My last visit was 20 years ago!
Hey a large thermoelectric generator module, paint the "hot" side with high-temperature black ceramic paint and adhere a large black heat sink to the "cold" side and you can generate electricity this way.
True, but TEG's are too expensive to fit on my budget. ..I am actually thinking of making a Stirling engine and use it. That's a long shot...but I will try it in future
Super thala..👍👍 most informative video and that coal thar idea 💡💡💡 is excellent.... Cost may high but it drastically reduce pollution..
Thanks Ji
When the grids down you can cook with it or sterilize water.
wow, I never thought of sterilizing water with this!...thanks
If we could able to generate steam from this mechanism, we could use seam in hotels for making Idli/Rice, boiling water, transferring the same water through insulated pipes to keep the temperature of food in hot conditions. may veggies can be used in this boiling water for cooking.
wow.... that's a really interesting and useful thought!
It is useful as water heater
Just Need manege to water flow, speed and need water storage tank
black painted copper pipes could do the trick....

mikka nandri bro
Fantastic
Thank you so much 😀
can i use aluminum foil instead of mylar sheet
aluminum foil is not very reflective. You can use tiny mirrors or mirror mylars. Or paint it with Mirror paint
Hi. It seems you are in India, where did u get the dish from?
Actually it was donated by my friend and its a really old one
Solid sale site buy dish
1. What about make biochar?
2. In the airless unit in which you make the bio char, make a gas fitting outlet. The emission will be "wood gas" or "syngas". Half of Europe ran automobiles on syngas/woodgas in WW2.
wow!...That's brilliant!
distil water from black or gray water
I have spended great time for waiting a person as you are. I think by this way one can be able to produce electricity thousands more time from normal way and this is already done in America. They have created this on very large scale and successfully they stored energy on a special surface which easily absorbed all of this energy and subsequently they get that energy back to meet different uses can you do this or help human kind like all of us
I am totally humbled by your wonderful comment sir. thanks a bunch!
I would to see if you could make the mechanism to turn the dish to follow the sun??
I am sorry...way beyond my scope!
I need help how to build solar cooker
Hi, I made a video a few years ago on how to make a solar cooker. But I used it innovatively to make candles.
here is the link for the video
czcams.com/video/Nro0EZgQBC0/video.html
Hope this helps
Brother I appreciate your great effort.
Have you ever thought/ tried to find, that, up to how much distance this reflected solar radiation would work from your parabolic structure ?
Additionally, kindly tell what is the ring type structure at the center of your structure and what is the material used to make it, as i am thinking that this focal point of structure and it will be receiving very high temperature?
What is diameter of your parabola? What is the max temperature can you reach with this reflector? How you measure it?
It's a 6ft parabolic dish, that much I know. I have taken any other measurements. It's very subjective though. There are a lot of variables to get to that measurement and clearly, I don't have the means. Thanks for stopping by
What's wrong with cooking? Unless your place has no backyard or balcony with enough sunshine it should work, it does for me :)
You see that I have placed this setup on road...which means no backyard or a place in the house. I wanted to test this idea and it worked. My goal was to test it myself
links to a pair of good quality gloves? where do you stay?
I bought this recently, It's good.
amzn.to/3NRhUD9
if you can generate the steam, then you can use this system for cooking
That's a good one too. What if we use this steam to generate power using steam engine...
Hello, congrats for what you did ! what is the max temperature you measured please ? I'd like to do the same to reach 400 degres Celsius, do you think it's achievable ? thank you by advance and why not exchanging about projects soon. Alex
I didn't have any thermometer to check the max temperature, but I don't think these reflective Mylar can produce that much energy. At least, not without some way to trap the heat without loosing it to environment.
@@VIDEOEPPO ok thank you very much
Bro please make a video on how to make an achromatic doublet lens
just checked what that is....and I figured its a daunting task and practically impossible for a person like me. Sorry Bro!!!
Is it true tht the per sqmtr or per sqfeet we can get 1 kw .....a solar panel only translates only 21% of ths(or efficient)
Honestly, I do not have that information
How can we use this heat to bake my bakery product, Where I need at least 200C for baking purpose.
hmmm...you've got me thinking now!
i displayed this in a science exhibition , but the curvature of the disk bought by my father is far more than i thought so my calculations went wrong , i thought of making a sustainable powerplant which purifies salt water using this principle , but though mine didnt work it was thrown to scrap , i got only 4 of 10, even that 90s project windmill got about 6 in that project and told ,"it wont work
You can make one with the plastic dish that they hang for promotions. It works too
@@VIDEOEPPO sir u think the same what I thought , it surprises me, i too thought of doing the same, but me father didnt liked the idea , as he told it should have much more curvature , but what he bought was a n aluminium lid
then as an alternative i tried with the tv actual dish , but i didnt got any myla sheet here , so i decided to cut glass mirrors and stick to it , but the area was very large , they charged a lot for the glass cutting , so i decided to work with the aluminium lid
it was 2 years back, in my 10 std , I tried another idea also, a cheap laser alarm with a laser and a some mirror , reflecting invisible laser several times around an object , but it need a simple circuit with few transistor and LDR but i didnt had solder iron , so i dropped that idea that day
@@gkrishna9841 Actual dish is probably 4 sq feet in area. You could get precut small mirrors. So can be found in the shops which sell tailoring products for ladies. They use these small mirror in embroidery. But you may need to buy in bulk. The cost of mylar sheet and mirror would almost be same.
Or better yet, look for "Space blanket" on amazon. I saw this technique from Nighthawkinlight
This model can dry a rice grain?
This one way too hot for that. It will burn it if the heat is not controlled which is quite difficult considering the position of sun in the sky is not the same and clouds are passing !
Hi Video eppo.
I intend you use this method for pyrolysis of waster plastic. Normal methods use more energybthan fuel/ energy produced
Great point!
did you do pyrolysis of plastic?
@@gauravdhumatker8210 I had to dismantle the set up for some reasons and hence could not try it out.
What is name of that reflective sheet ? It has adhesive behind it, as i am trying to make little one with satalite tv dish...
Yes there is adhesive behind it. Its reflective mylar sheet. The one I have used is used to stick on the window and serves as a one way mirror. In this case since the back is opaque, its 90% reflective. Hope it helps.
@@VIDEOEPPO thank you very much. I was searching for the exact name of this reflective sheet with adhesive on it.
Sir can you help me to make stand arrangement of parabolic concentrator
oh, Sure!
Sheet name & mm sir
Its a regular reflective adhesive mylar sheet. Should be available in sticker or window shops
We have a company our mainly power consumption in produse heat to dry sulface paper in coating a chemical layer and I think why can't we produce heat air thru parabolic mirrors our e,bill is near 4 lac per month
That seems like a fantastic idea. You could even trap the heat in insulated containers and direct the flow of hot air through tubes
Mylar Sheet ..Please give me the link to buy it online.
its too expensive online. Try searching for it in the local market. It will be a lot cheaper
Bro please make a video on how to make van de Graff generator
My vandegraph generator is a long pending project. I might make it soon
@@VIDEOEPPO thank you sir, and please try to make it using items available at home
@@shivamsinghrathore8119 That's always the goal., But lets see
Do you do wooden dinosaur table lamp?
Please sir
sure...I will doo it soon
@@VIDEOEPPO Ok sir
That silver sheet name you spelled but I can't observe .Ok whatever it is. Did you tried with aluminium foil. Just waited for your video whats next. Well try
Aluminum foil may not be good. It does reflect light that much. What I used is mylar stickers that are used in one way window. Mirror Stricker
i like your hat :)
me too...lol
Can you make videos in Hindi
I made a few videos in Hindi, But nobody watches...SO I am not making them anymore
@@VIDEOEPPO but your can try
Use it to roast plantain.
hahahah...really bro! but it would be a fun concept actually
I can't understand him.
That's something I get often. But its difficult for me to speak any better
