Solar Concentrator Hot Water Pot Boiler

[JustinJJHCS1]

yeay Good going... you can get one that makes Heat for your house.

[izzzzzz6]

what was the last thing you said in the video about not needing to do something? when you are not cooking you could use the dish to make electricity, once you have free electricity you can use it to make hydrogen for cooking and heating in the evenings, great work, i would be doing this now if i had my own land

[LiquidChem]

One thing I'm starting to notice about fr4esnel leses and parabolic cookers, is the safety thing.. for one thing, someone can easily go blind looking at the beam, or whtevers being burnt or "illuminated".. I know how dangerous this is from experience! This is basically a high powered laser type of energy, very condensed and concentrated..and HOW easy would it be for a cat or other animal to jump on the dish, (most are close to the ground), and then its going to get gory.

[warmvalleyfarm]

@LiquidChem This is DB and you are correct it is dangeroujs to the eyes and one with children should probably not have one. Jumping on the dish is harmless. All the light is concentrated to a focal point somewhere away from the surface. But if a pet did happen to locate itself into the focal area that would probably be the last time it would get near the thing.

[810max]

hahahhahahahhahahha

[bloodandwinearered]

I'm sorry, if you have steam, you can turn a turbine or a engine. This is more that possible and you just proved it. Imagine a huge, perfect dish in Nevada. Steam = electricity, desert = sun, Nevada = lots of empty space.

[cdltpx]

Great music you would love Dakota Staton and Diana Washington. Great music that will never die reason so much of it is in your better movies. My exwife was a jazz lover she even has pictures of her with Louis Armstrong when he would visit her dad. He was a jazz trumpet player that turned craftsman to live but her uncle Leed Collins toured europe and his widow wrote the book "Oh didn't he ramble". Her dad told me the musicans lived large but always came to him for those ends when they were short.

[desertblbuesman]

@cdltpx thanks for the great story there.

[cdltpx]

You have got to rig up a pressure cooker to hang from that and you will have the perfect cooker many meals require you get pressure cooker up to steam and you can let it set and cook for an hour and a roast that would be so tough you need knives would be eaten easily with a spoon. I have got to get my hands on a larger dish. That is a quality setup a pressure cooker would have to have handles removed install securement locations but would work ten times better than just a pot.

[desertblbuesman]

@cdltpx by god you have something there. I took the handles off the pot I use (they smell very bad when burning) and made a rig out of stiff steel wire. This is a 6 foot dish and I find it close to ideal. Ten footers are a bit big to handle and smaller do not produce enough power. Funny, I never used a pressure cooker and did not know they would post cook like you state. THANKS!

[cdltpx]

@desertblbuesman Pressure cookr at the wally will set you back you can get a pressure cooker at a yard sale or thrift store they usually are $10 but need parts even at $10 you have a deal you want a used one asl me cayse you are going to have to modify that thing to handle the extreme heat provided by that excellent collector. I have tried using smaller dishes very true they are cute. That thing rocks! Go online read the instructions for a pressure cooker you put food in there you want to make

[cdltpx]

@cdltpx sure you cook it or you run risk spoilage pressure cookers are IMHO ideal for solar collectors because you might have 30 min sun shade mores sun well while it is sitting with out sun it retains much of its heat and is still pressurized. When you take one off the stove you have to run water on it a while to get it to depressurize and as soon as you turn off the water it will begin to repressure in the sink so yes it is ideal for solar. Plenty pressure cooking video on YT you will enjoy.

[LiquidChem]

@cdltpx most stuff can just be cooked in a pan or pot. . almost all meals I make or things i cook to eat, I rarely ever use a lid and i get by just fine. its just like heat from a stove, even hotter so faster. minutes are nbeeded not hours.. if you want oven food, thats different, but still doesnt need pressure or a lid. just sayin.

[cdltpx]

@LiquidChem We cooked a roast Sunday an hour on the stove and you could use a fork to serve your meal. Reason I suggest using pressure cooking is your cook time is greatly reduced the food is great too. When you have solar a cloud can cause loss of energy and can cause your food to spoil a pressure cooker will still cook since the pot is still under pressure if a cloud covers the area for 15 min. Please just look at a pressure cook video you will see I get them at yardsales under $20 easy.

[underwoman261]

Nice!!

[desertblbuesman]

@underwoman261 Thank you

[chmellen]

How do you regulate heat?

[MartinJWillett]

To improve the system you need to find the focus of the dish and put a dark target there. A laser pointer pointed anywhere at a parabolic dish should be focused to the same point.. You need not use mirrors, a good metal foil will work almost as well, and it would be quicker to make.

Because it is parabolic you will get reasonably efficient heating even if it is not pointed exactly at the sun. However simply put a tiny hole in the middle of the dish and you can make a sight to aim it at the sun.

[Pennythreepointzero]

i like the music.. oh and good job with the solar collector too! :)

[desertblbuesman]

use the gas stove.

[n2e3i4l5]

@desertblbuesman

HI what did you use for the arc tube,did you bend it or was it already bent-

[desertblbuesman]

@n2e3i4l5

Electrical conduit hand bent

[n2e3i4l5]

@desertblbuesman metal or plastic ? and thanks for replying.I,ve got a big dish like yours and all the mirrors ready.I just need a spare day to stick em all on.I,ve already got a small 90cm dish in operation.I can fry with it but it takes about 17 mins to turn water into steam.I know the big dish will do that in 2 or 3 mins.Also I,m going to invest in a camcorder soon so should be able to upload a view.

[presbarkeep]

what happens when you want hot water at night time?

[djangobelgo]

Not to be the party p00per, but is there any way to use this when people actually eat? That is: at night, after sunset - universally so, all over the world.

[magicyte]

@djangobelgo That's probably the most retarded question I've ever seen a person ask about solar. I do hope you have that one figured out on your own.

[asceticpodvig]

@djangobelgo are you always observing Ramadan? I eat during the day.

[Sunmocker]

@djangobelgo Transfer the food to ceramic cookwear. Also universal. Keep the food insinuated well and it should keep warm for 3-5 hours. That should cover "after night" eating. You just have to think ahead.

[datzfast]

@django belgo yes campfire, it takes solar energy stored as cellulose and returns heat. another way would be to heat molten aluminum alloy a cook with it hours latter

the best way eat before sundown most people do

[n2e3i4l5]

@djangobelgo Of course there is .You cook during the day then wrap the food in aluminium foil and place it in an insulated container.With liquids use a thermos flask.It will still be boiling hot several hours later,

[paul8kangas]

Excellent solar over, muffler paint, recycled mirrors, & TV dish.

[gaiatechnician]

Really nice video and tribute. Thanks again.

[YancyAdan]

Does it track the sun, if not then thats lame

[ChazZeromus]

Ugh vote me if you experience slow youtube D:< I really wanted to see if it boiled the water!

[thetubewatcher33]

I really like that someone can take scrap and make something beneficial with it. Thanks for posting.

[gaiatechnician]

Hi, desertbluesman and others. I have done experiments over the last couple of years that show that the parts of the dish in line with the path of the sun stay in focus longer. So put your mirrors on that line first! I have started on "clam shaped" reflectors in the last few months. The clam shape is new and you design it with lasers to give a "clamshell" that will concentrate the sunlight for one or 2 hours without moving the reflector. (You have to move parabolic more often).

[keneyed209]

hot

[hukt0nf0nikz]

absolutly awesome!!!

[TechnomancerMorhion]

That's a really nice idea. I've used a fresnel lens for the same purpose, yet I never thought of using a satellite dish and mirrors. It makes obvious and perfect sense to me now that I've seen it. Thanks!

[Infoseeker91]

Damn Smug Hippy jus turn on the damn stove and cook already who cares that the sun can boil water........ooooooooooooo....­...like nobodys thought of that before.

[desertblbuesman]

you are a funny guy. :) I care that the sun can boil water. And make my electricity. Its how I get along. You do what ever floats your boat, pal. One thumbs up for your honest comment.

[rickmobstah]

@Infoseeker91

and that's how the world became shit, because niggers like you arrived and populated the world, soon this world will end due to flawless ignorance :)

[schr4nz]

@Infoseeker91 incase you aren't aware people use methods like this to generate electricity and make money off the electricity companies in the process. i myself am looking at getting together with some engineers and welders to do something on a massive scale...

[breakandstuff]

nice

[christo930]

Why does a 6 foot solar reflector/concentrator to boil a quart of water? Is the unit just very inefficient? I did notice that a good deal of the dish is mirror-less. If every square inch of the dish was mirror, how long would it take?

[desertblbuesman]

The video says, it boils 6 quarts, but the pot I have been using is more like two gallons, or 8 quarts. The unit produces around 2000 watts as it is. I did not need or want to bother filling every square inch, but yes it would produce more power that way.

[christo930]

Sorry, I guess it looses the sense of scale. It looked to me like the pot was holding a quart or so of water and you say in the video it takes 15-20 minutes to boil it. 2 gallons in 15 minutes or so is much better, seems about what it would take to boil it on the stove. Not bad for discarded mirrors and a dish. Nice job.

Sorry for the misunderstanding.

[desertblbuesman]

no problem. Actually, if it is full, it take a while longer. I usually have it half to 3/4 full. I just leave it and forget it and get it later. So the time measurement is not scientifically tested :) It is as fast as my propane cook stove I think.

[KasinH]

You painted the water pot with black paint?

[desertblbuesman]

Yes I did, with muffler paint I had around. After, I realized better putting it on a camp fire to blacken it does just as good and no paint used. A little animal grease, or maybe vegetable oil on it then onto the camp fire gets it cooked in and black.

[7188181]

It's extremely common and acceptable to use flat black paint on materials used in passive solar energy projects like this.

[KasinH]

But you wouldn't have to paint the pot black would you, with all that available heat? Or does the black paint diffuse the heat so it's not so focused on one part of the pan?

[desertblbuesman]

A shiny surface reflects the light away, black absorbs it. it did heat up before I blackened it, but it was much faster after blackening the pot.

[desertblbuesman]

It works fine. I was referring to a non consumptive and non polluting alternative to purchasing paint.

[Marnoble]

nice music!

[beancube2008]

You can drive a Tesla steam turbine. With a pressure cooker, tubes and some jet hosts to push number of the 3" disk Tesla turbine over 10K rpm. It is a lot of electricity for a regular 8 hours sunny day. Money you saved can be used to start a business engineering it or many other things. It means freedom, men!

[0urGaia]

Or just run the steam captured through a electric water pump which should generate electricity. May not be as efficient, but would be a cheap modification.

[Hobohube]

Lved the music. Great job. Thanks

[luc59457]

love it

[callmeshane303]

NIce vid.

3 tips.

1. write a lits of your relevant points.

2. write a script and practice it.

3. Be specific and to the point - no waffling on for 10 mintes.

Use editing of the film footage and perhaps some voice over.

Leave the music out of it. - or play it as quite back ground music.

[desertblbuesman]

many thanks for the tips. though your tips now seem obvious to me after reading them, i really did not have a clue on how to organize it. thanks again.

[acorntechnique]

To be frank I think he's being rather condescending as despite his list of your 'failures and faults, - I understood you very well.

Many thanks for uploading

[acorntechnique]

If your going to write stuff like that regarding someone's lack of style as you perceive it, wouldn't it be far better to direct your thoughts to the channel user privately?

Or do such levels of professionalism only apply to others and not you?

[smartkart]

Just take a look at his own crap videos and you'll see he's nothing but a fat, slob hypocrite.

[limeytrash]

You tell him his video is "nice" then proceed to criticize him? If you're going to pretend to be such a professional, maybe you should learn to spell first. It makes you look very foolish (and illiterate).

[smartkart]

I saw your "videos" of your ugly fat ass licking a jar of Vegemite and giving birth to Jesus. And you go around giving advice on making professional videos? Since you're from down under, I'll bet you walk around saying OY MATE a lot, right?

[anutshell]

Nice.. thanks for the spark.. it's ideas like yours that will solve the energy crisis.

[TrickyNekro]

I just found another way to heat up my water for nes'cafe in the morning...

Nice...............

[happiiness2000]

Green Peace. Thanx 4 posting

[djangobelgo]

I only eat hot food and hot drinks at night, after sunset.

[shamwowwow]

Well, maybe people like you shouldn't be wasting your time watching solar energy videos on Youtube?

[djangobelgo]

Aha, yet another person who can't stand the idea that the technology is a joke, and that it humiliates poor people.

It's not because you like your own gadgets, that the people who need reliable energy also like them.

Think of it, willya.

[smartkart]

You sound like a real nutcase.

[whannes]

why not just get some logs, haha.

[Xatruch702]

too much hassle for such a small task.

[MrAfroSheen]

Too much hassle being able to cook food for years and years using totally free energy?

[tirapelli]

your cat is a clone of mine! lol, even the "ear hair"

[desertblbuesman]

That ear hair is how she got her name "Tips" :)

[erickhiram]

AMigo! que cosa más maravillosa! FELICIDADES!! Lo vamos a copiar. Que bueno que lo publicaste.

Best ever seen on you tube, Thank you!

[desertblbuesman]

Gracias, Amigo!

[mountainmanrab]

here mate that will no work in belfast

[desertblbuesman]

the sun NEVER shines?

[thecrazyaviator]

ok, now make electricity with that steam using a generator.....i challange you! :-)

[desertblbuesman]

It would be possible, but would also be overly complicated and costly and a maintainace nightmare for little power output. I use PV and it is so simple and totally reliable and in the end many times cheaper. But agreed, it would be fun!

[thecrazyaviator]

so you decline the challange becuase its too complicated....not the American way.

[desertblbuesman]

The dish is lousy at making electricity and the PV is lousy at heating water. Not sure what your talking about "not the American way.". I enjoy and appreciate your comments.

[thecrazyaviator]

its not the american way to say i wont try something because its too hard.

you may not agree with me, but its people like you who are the best hope for our country.

you have a strong knowledge of how these things work so if you put your mind to it...you may be the one who invents/discovers a new energy source. we could say bye bye to oil!!!

[MrAfroSheen]

He's demonstrating a solar concentrator cooker, not how to generate electricity. You seem to not realize it would take a tracker to stay pointed at the sun, a steam engine and a generator, meters, batteries, wiring etc etc. You can find plenty of info elsewhere on that.

[MrAfroSheen]

thecrazyaviator, I challenge you to get off Youtube for awhile and learn to spell words that many of us learned to spell by the third grade.

[patagoniasinrepresas]

the song is (--_)zzzzzzZZZZZZZ!!!!!

[AndreONEz]

That's great

[desertblbuesman]

thanks. it is handy.

[markduyvesteyn]

you can easily work out the KW output of this.

Power = weight x 4.2 x change in temp / change in time (in degrees Celsius)

from above assuming it boils in 1.5 Gal = in 15 mins, assuming that the temp difference is 75 degrees, the dish out put just under 2kW

[alanor76]

First: I think this is an great demo of what can be done with cheap bits. But you need to take care with the power in that thing. If the diam is 2M the collecting area is about 3 SqM and on a hot clear day you might get over a KW per SqM from the sun - depending on where you were. Knock off 30% for imperfect construction and that's still a good 2KW of power in a few sq in.

Second: I went to Itunes to buy that song. They offer 9. The one I got is nowhere near as good. Where's this one from?

[desertblbuesman]

thanks for the comment.

the tune came off a cd, a good one, "great ladies sing the blues". an excellent compilation. the song is public domain.

"still a good 2KW of power in a few sq in."

did you mean M^2?

yes lots of power in these. 2 M is a good size for boiling water fairly quickly. can be done with a smaller unit. larger starts getting hard to reach easily.

care must be taken with these. sunglasses always must be worn and the farther the thing gets off axis, a focal line extends away.

[VitoVern]

Thanks for great video and the fantastic tribute to Nina Simone. I look forward to that album.

Boiling a gallon and 1/2 of water in 15 minutes is impressive. What are your favorite food dishes you have cooked on this unit....vitovern

[desertblbuesman]

Hi VitoVern

Seems comments are not getting left sometimes. Second try her Nina is one of my favorites. This tune being one of here more standard types, but I love her "off" stuff even more. SO original!!

The dish I have not used for cooking, just water boiling, but did boil up a large pot of rice and meat for the dog once. Started with sun just hitting the pot, by the time the sun had passed the full pot, the rice and meat were cooked with no movement of the dish. Advantage of a large target.

[desertblbuesman]

Warning; turning these units to the north can be dangerous and develop a very long focal length that can set fire to objects to the north of the unit when the sun is high and the unit only somewhat inclined.

[gaiatechnician]

I have heard of that but not seen it. How much longer is the very long focus? Someone had a picture of a global sun oven with a similar problem. In the case of the sun oven the reflectors can bounce the light off the glass and your focus is to the south. (A guy accidently burned a line on a wooden fence!) About 10 ft away. Thanks for the info. Maybe people can design the mount so that it cannot turn fully to the north?

[xPattyBrown]

Loved the demonstration and information. Thanks for sharing!

[PukkPukk]

You could put a hotdog on a stick. Or a nice river trout.

[desertblbuesman]

Yes for sure. If you kept it a little ways off the focal point. If on the focal point you would have an ex-hotdog. :) You have to wear sunglasses when using these. it will fry the eye.

[har0sownage]

stupid song but rest was kool -.-

[PukkPukk]

How long did it take for the pot to boil?

[desertblbuesman]

about 15 minutes for 1.5 gallons on a good day.

[har0sownage]

he said 10-15 minutes

[rs4pl]

thats pretty cool and on topic in my physics class. We where actually boiling water in a smaller glass container attached to the mirror.

Can't imagine how hard it was to adjust the mirrors to focus on the focal point and find it. good job dude

[desertblbuesman]

Hi

it was easy as the satellite dish had the proper parabolic shape already. I just glued mirrors on. You can do this with any satellite(parabolic)  dish, large or small. A satellite dish focuses the incoming "rays" hitting anywhere on the dish(in this case light as opposed to TV signal) onto a receiving "Point". Look at the receiving apparatus on any dish and you will see.

[WDX7770243546]

4:00 mmm hot, she look so fine. LOL!

[desertblbuesman]

oh yeah!

[WDX7770243546]

lol how come it reminds me of microwaves?

light waves instead of radio waves?

[desertblbuesman]

Yes, a radio wave to light wave device conversion.

[WDX7770243546]

LOL Yes!

[2JZEDDIE]

dat der u got ther is a deathray lmao

[skittykillzz]

lol sweet

[rigidhawk]

we have one of these in our campus. recently I saw one cooking potatoes by using it ^__^

[deefromott]

thats brilliant. or i'm slow. but it's still brilliant.

[ultrakool]

Can you take out incoming ICBMs with that thing?

[bopn]

awesome.
