There You can read my experiences while I’m making that particular Project. Thank you. Happy Making.
My brother, this is fantastic! I want to try a portable version for camping. Thank you very much for sharing your experience 😊😎😊😎 🇦🇺🇦🇺
I have only been using solar water heater (different design) heated water For more than 8 years now for bathing etc... 🙌🙌🙌 Little proud moment 💪💪😳
prem singh pls share a photo
Did you make the spiral coil. And did you use a thermal storage container like a ice chest ?
Nice job. Enjoyed the video.
Several years ago, I had a similar design. But, I used a reflective metal sheet, which eliminates the step of applying mylar film. Also used bearings around the pipe, mounted on the end panels. So, the reflector pivoted around the stationary water pipe (angled towards the south, at the # degrees from the Equator). Then, with the reflector balanced around the pivot point, a small DC motor (controlled with 2 photo resistors and an Arduino NANO) can be used to track the sun. This solar tracking assembly can be built for less than $50.
Also, a standard thermostat valve from a car engine can be used at the hot water output to optimize the water flow through the parabolic reflector, so a small dc pump (with automatic pressure shutoff and expansion tank) can be used at the cold water input to 'feed' the solar heater.
A system such as this is ideal for hot water tanks and in-floor radiant heating.😎
Can you give me the reflective angle pls
@@uwulaanbar9176 There is no set angle, because the sun changes its vertical angle from summer to winter and the horizontal angle changes from morning to sunset. The parabolic mirror tracks the sun horizontally throughout the day, reflecting the sunlight onto the water/fluid pipe, like a reflective lens focused on the pipe, opposite side from the sun.
The pipe is best set at 90 degrees to the angle of your local midday sun at winter to optimize it under the worst scenario.
@@TheOleHermit what was the total fabrication cost of your design?
@@donsuji1658 Thank you for your interest. However, life happened, so I never had the opportunity to build the monolithic dome home to complete the project and didn't do a cost analysis. But, I believe in its feasibility, because of it's simplicity.
The solar tracker circuits are available on Amazon:
www.amazon.com/Solar-Tech-Power-Analog-Tracker/dp/B00F74H9SA/ref=sr_1_13?crid=2E3KE3LESLFGU&keywords=solar+tracker+controller&qid=1666191442&qu=eyJxc2MiOiI0LjE2IiwicXNhIjoiMy4zOCIsInFzcCI6IjAuOTIifQ%3D%3D&s=lawn-garden&sprefix=solar+tracker%2Clawngarden%2C146&sr=1-13
The rest depends upon the specific design of the system. The radiant heating and water heater costs are the same as conventional designs.

Mr. The Hermit...They're looking for simplicity here. Everybody can't get the things, knowledge, electronics, programming, wiring, you require. No harm intended. Just saying.
So many things that could be said here however I will not be hypercritical. Super cool. I will overlook the obvious imperfections thanks for the video.
I love how you make these projects simple and easy to grasp
Only the tiny qty of water in the pipe will get heated, the rest will not because there is basically no convection path for the hot water. As soon as that runs out you will get cold water. I would remove the tap and take the heated water back into reservoir, and put the tap on the reservoir. As a bonus insulate the reservoir (say inside lots of coconut fiber or styrofoam), and you'll have hot water even when the sun temporarily disappears, or in the evening.
But with such a small amount flowing through the heated pipe it will bee heated that pipe is probably around a 1000 degrees Fahrenheit
Black antireflective dye for copper: 20ml distiled/deminerlised water, 2,5g AgNO3, 12,5g Cu(NO3)2. Warm to ~50 deg. C, apply with paitbrush. Rinse with water afer 3-5 minutes.
That's defiantly worth replicating. Good one
Iss k right r left mein (parallel). 2 mazeed pipe lga Ker germ Pani kee storage capacity ziada kee ja Sakti hay.... capacity ziada kernay k iss k ilawa aur b tareeqay ho saktay hein....baherkaif ye buhat nice aur simple project hay Jo her koi aasaan se bna Sakta hay.
Coiling a smaller tube will increase the time of exposure and decrease mass, thereby heating the water faster and hotter and potentially reducing project expense.
I too feel so
One summer when the hot water heater in my motorhome went out, I heated my water by simply using a very black garden hose connected to the water source. It was so scorching in the shower, I had to mix the cold water with it to keep from being boiled alive. I am not sure how that would have played out in the winter, but being in the Deep South, Summertime Sun was more than adequate.
I do that right now evey day.
Solar power is endless. Start tapping its unlimited potential.. If you enjoyed this video CLICK the LIKE button, Otherwise KICK and KILL the LIKE button..😁👌👍😉
How many gallons or liters per minute can you get out at 100 degrees C or at shower temperature and if you made it a lot longer you could get a lot more right I also saw where you can point it east and west where you don't have to track it to follow the Sun constantly you can just change it every few days or so but when it's pointed along the track of the sign you don't have to have it track the Sun good job keep up the good work I've got a lot of thoughts along these lines like preheating the water Etc minute by minute
You might paint the pipe black and put another reflector above the pipe about is big as a beer can cut just to catch the extra light bouncing off
New Physicist just curious would glass over the top increase temperature? Awesome build by the way👍🏻
Solar is hard to get for 93 days in cloud covered Cass county Michigan. Many of us are vitamin d deprived in this area so my Dr told me. Wish I could do this it looks amazing.
New Physicist, would adding a glass top over the parabolic device increase maximum temperature of the pipe?
avasva has very useful instructions with all details I need
AVASVA IS A FAKE SITE THAT WILL PUT SPYWARE ON YOUR DEVICE
in the video...please also show the temperature of water that is in the water barrel by putting the thermometer into it...
Useful for RV dweller when parked and will save battery juice. Might also be used to heat van.
Coat the end pieces with reflective material too, so the wood is not scorched. As is, you can start a fire fairly easily.
This was my immediate thought looking at this; be very careful how you align it.
The thermal degradation and ignition point of wood and plywood may be generalized by the following: 230° to 302° F (110° C to 150° C): The wood will char over time with the formation of charcoal. If the heat is not dissipated there is some possibility of spontaneous combustion. I doubt this device will get that hot and it has a lot of heat dissipation.
@@petes2559 The slightest misalignment and you will get a hotspot on that wood that could easily exceed those temperatures.
The fact that the mirror is parabolic and focuses the sun is the problem here. There are plenty of RUclips videos of people starting fires with parabolic mirrors, you don't want to do that accidentally because you didn't want to spend a few pennies protecting the wood with a piece of mylar or aluminium foil.
I doubt this would provide much hot water, as the water flowing from the bottle would quickly cool the pipe. Painting the pipe and the water bottle black would help. Using a larger diameter pipe would help also; this would increase the amount of water that stays in the pipe and increase the amount of metal to absorb the solar heat.
A smaller diameter will result in less hot water but at higher temperature
The output water temperature is totally dependent on how fast you get it to flow through the pipe. Much of the heat loss is radiated off the top of the pipe so a high temp insulation on the top of the pipe would help. Something like mineral wool with a melting point of 2150 F glued on with ST-1000 thermal glue can withstand temperature up to 950°C or 1742°F. Problem solved.
Yep, I made one of these in 1960, worked very well.
On which country please? I leave in France. Can you give us an approximative value of liter per hour or min hot? Many thanks
Great project. Thanks for the video.
Tip: While working on something that you use a drill as part of the steps, you should use you're drill like a drilldriver" simply by locking an screw driver bit into the drill & use it to drive the screws. Save a lot of time and energy.
Muy buena idea, vi algo parecido en el que hacen pasar una tubería por varias columnas de latas taladradas y tapado con un cristal
great product id like to live in a boat
in key west florida, so what i see for me is a 50 gallon tank,, with a solar pump
from the salt water to the tank then use it for showering. possibly some cooking. then
another tank with fesh water using one gallon from that tank, to wash off the salt water.
Thumbs up, very nice tutorial. Good luck.
As a demonstration this is ok, but if you replace the plastic bottle with an insulated metal tank ( an old hot water heater for example) at the top and plumbed the bottom outlet to the tank also the water would circulate when heated and the tank would get very hot. As it is insulated it would store the heat.
Be very careful with parabola's. My neighbor had a curved copper roof on one of his bay windows. The surface focused the suns rays on his soffet and caught the house on fire. No sh*t.
You need to replace the wood with metal. Ad the wood dries out. It lowers the flash point. After that, you're golden.
needs a big insulated tank for the hot water to be pumped around the system, instead of a straight pipe needs a coiled pipe wrapped around a pole, the coil pipe painted black can run a solar powered water pump to do this .
your wrong with a pump inline the water is evenly heated
dont forget my way its pumping round ,so i dont see your point , its evenly heated
if you look at how a central heating system works don't that only heat one part till its pumped around?
only one way to find out make it , get back to me lol
Good idea bud.
Good idea but you need circulation system to heat more water and double insulated tank to keep warm water.
Objective Criticism why? It's for hot drinking water not a bath tub! Jeeez
اختراع جميل ..بس لو تكثر الانابيب .وتعمل بلف حراره حق السيارات .ترموستات يفتح عند درجه معينه 82داو92وتعمل قنينه مغطاه مثل السخانه .
İncredıble idea.Thanks for video.
wondering why you didn't use a coil instead of a line in the heating focal point. were you trying to have the reflective less obstructed? Also why didn't you make the sides reflective? ty
Sides don't matter. They are parallel to Sun rays if oriented right. They won't reflect.
Use a better thermometer. The idea is good and I should be storing that water in a water heater.
Try using glass tube with black coating or black granules and cover (opposite side off mirror) 1/2side of tube with reflective tape you can show atrem coming out of tap that's 100 ℃
My solar water heater: 5 gal bucket, round glass from microwave oven, water. Place water in bucket, place glass on top of bucket, place in the sun.
Drinking Water?
John Bailey e
thats a heat trap?
Good video,,only thing to change is use a coil of copper instead of a single line
the physicist who cant differentiate 100 C with 100 F.
good luck in your innovative ideas
Great NOW WE JUST NEED WAYS OF COOLING THINGS IN DESERT ETC GETTING COLD WATER.
I'd just move, much easier that way.
El agua caliente esta en la oarte superior del deposito, es decir que convenientemente solo sacaste el agua fria de la tuberia lo de abajo estara superfrio
i will copy that and i will put a solar tracker, i like it ;) tks
Much adieu for a cup of tea.
I think I have a new summer project. Paint the pipes black, use multiple pipes? Maybe a black plate over the pipes? But I think i will wear shoes while cutting :-)
طبعا تجربه فقط. لان الماء سوف ينزل ثم يبرد النحاس لهذا فهي للتسليه فقط لا يوجد استمرار بالماء الساخن وايضا بصيف وبالنهار فقط لا بستفاد بالليل منها ولا بالشتاء
Es un milagro que este indú este de una pieza, cero seguridad para todo, sin zapatos, sin guantes, sin ni una wuea, pero el experimento es bueno.
My suggestion is to make several lines instead of just one copper pipe to improve thermal efficiency.
The water in the bottle already has a temperature of about 30 degrees. If the copper tube is painted black or dark blue, it will increase the heat🔥.
That can probably accommodate more than just 1 copper piping, giving nearby people access to their own hot water as well.
Very interesting video, keep up the good work. Thanks !
This is cheapest and awesome concept!!
this is amazing. have you built something similar to sea water evaporation to get clean drinkable water using solar?
Thank you for sharing your idea. I like it.
With a one way valve and a return line, it could probably keep an entire tank warm.
If it was longer, it could support a higher flow rate. The pipe should be painted black, too.
This is the best!
Why do you not try it with a grid and a plastic tank to circulate the water to heat up that much. great idea with the solar film I would like to try it
Put a gallon of water under the hot sun, you will get a hot water same like you got. but the idea to make a solar panel is nice
Good
Nice
Лучше будет убрать провисание шланга между нагревателем и коллектором. Напрямую - будет лучше проход теплой наверх и холодной вниз воды. А так - теплая вода блокируется.
В прямом виде эта бутылка работает лучше как коллектор (это планировалось, ведь отражатель сделан под углом к поверхности).
Еще я бы сделал нагревающуюся трубу больше, пару дюймов. И зайчиков больше поймает и конвекция внутри больше.
Как вариант можно пропустить внизу доп.трубу (шланг) от крана до низа емкости. А забор воды из ёмкости сделать с верхнего уровня - там вода горячее.
ну и конечно, следует зачернить трубу нагревателя таким образом, что бы толщина покрытия была минимальной и смотреть не по цвету а по теплоприёму (теплопередаче).
bravo kardeşim. eline sağlık.
I really have to wunder........ Do people even think before posting comments and questions? Oh and yeah that thing will boil water in seconds! Just don't open the valve all the way and you will have a constant stream of boiling water. My satellite dish solar fire can boil a cup of water in less than 2 minutes!
Hello, pls can you give me the measurements of everything because I'm making this project for stem
It will not work at all. Since there is no water circulation, Online the amount of water traped in Copper pipe will be heated.
Also There sud be Black coating on Cu Pipe to absorb more heat
Jordar bhai
Painting that jug black would provide the same results with much less effort and expense . It may take a bit longer to heat the water but that can also be improved upon easily
Good job...keep it up..
I think that it is better if you paint the copper rod with black paint inorder to change the UV rays of the sun into heat as much as possible
Sería bueno que tuviera un retorno para cuando la llave esté cerrada, de esta manera el agua circulará por diferencia de temperatura entre la cañería y el tambor.
Exacto. Me voy hacer una
muy bueno mi amigo, muchas gracias por el video
if you connect a steam engine here and loop the water, you can get a lot of traffic or electricity.
si aquí conectar el motor a vapor, mientras que el agua de repetir, puede recibir una gran cantidad de movimiento o la electricidad.
awesome!! hmmm.... why dont you paint that copper tube black, for example with black stovepipe paint? would this not transfer the radiant energy more efficiently? just asking...
I should have done that too. Thanks 😊
Great work!
Well I need to see something how to warm the water in extremely cool
Cold?
If you painted the outside of the pipe black, i bet it would get even hotter!
The power of a parabolic trough can melt rock and would fry any paint added to it. The idea of thos type heater is basically instant water heater and if you recycled the water back through tank you could make it well above boiling temperature creating steam which could distill into pure water.
Wow ,, That's great ,
I know it depends on air temperature and starting water temperature, but, what is the average usable rate of flow with this size device?
You recirculate the water and can heat 200 liters of water in a morning
If the surface of the copper tube is blackened using any of the simplest methods, the heat transfer will increase by 15% or more.
nice one homie
Good job keep it up
sachin a, thank you.🌸💕
That water bottle also absorbs sunlight so it has some amount of heat....then the copper is the best heat conductor so these two combination makes water with more heat....
Thank for your working how long it take for heating water
The last item, the solar water heater, would be much better if you piped the hot back into the tank letting the water circulate by convection heating all the water in the tank !
Wldone bro give a black coating to the copper pipe
sathish kumar, Thank you.🌸
A black coating to the water tank will help pre-heating too.
New Physicist , what are the measures of Qs and Ps?
good comment
I know it's more complicated but
If you replace the linear copper pipe with another smaller diameter
and it gives it the shape of a pier. It will increase the exposure time and with it the water temperature.
Congratulations
so the smaller the diameter of the pipe, the hotter it gets due to the heat exposure is more concentrated?
This is true, but if the diameter is too small, you run the risk of losing some of the radiation in the focal line.
So one option is to flatten the tube to make it thinner in height but wider at the same time.
Лучше было бы сделать с замкнутый контуром. Вода нагреваясь поднималась бы вверх, а на место разреженности конвекционно подходила бы холодная вода. Так можно нагревать более объёмные баки с водой. А уже вывод общей подогретой воды через кран сделать отдельно
Nice thank you bro
This is so cool!
why do you use a 50 deg C thermometer and say more than 100 degC??????
That is Fahrenheit
Jack Tam He is asking how OP knows the temperature is 100°C if thermometer doesn't go up that high.
Kinda leading me to believe this is impractical as well
Всё верно ! Термометр слаб . Чтобы убить большинство микробов , надо довести воду , хотя бы до 70 градусов цельсия !
@@user-jc4bw7fq4z Да в этом видео вообще ни черта непонятно. Может эта трубка загодя грелась полчаса, чтобы нагреть один стакан воды. Да ещё и при окружающей температуре +27.
На самом деле , схема-то рабочая ! Глянь на солнечную печь Go sun . Но эти ребята , свернули где-то не там . Но думаю , что у них все еще получится )
Brilliant
Nice work. Hope you got a cordless screwdriver, and a thermometer that measures over 100 C or 212 F.😉
Nice work... I simulated it
Very nice!
Superb
Just put a long big iron. One part goes outside and one part goes inside. This way you do not need a reflector.
Im a physicist captain... not a plumber ! No need for soldering faucets or installing pressure relief valves, it's not like water expands when heated...right?
The pipe on the focal axis. Why is it not painted black? Use small dia long pipe, coiled or multi-loop if needed The effect could have been more pronounced.
A brilliant job, nonetheless.
What to do with the water at 100 deg C?
If you could convert into electricity, it will be a fantastic thing to do.
yes this is a simple sisteme the primary now you take a boiler with isolation and make the secondary in the boiler you have a copper pipe that make hot 100ltr water at 50grade celcius that is the thermodinamic sisteme
Pretty cool but can you use it to heat your home 😊
Bro how did you draw parabola in a sheet any software is there ??
Paint the tube black and it will raise the temp
