I dedicate my weekends to burning wooden sticks, and until now I had to make do with plain old boring matches. This large mirror is just what I need to reinvigorate my favorite pastime..
i bought one of these from this company a 13 inch model. yup it'll burn sticks. now should i hook it to my hydro generator or a flat piece of stainless for a heater element to cook my steaks on? i have 3000 8"round mirrors and some are going on a 60"sattelite dish then i'll do some cooking
Ive been told that granite melts at about 1250f...Ive also heard theories that some of the large stones in say Teotihuacan were carved using mirrors like this. Opinion?
you should set up 50 of them shining off eachother so you have 8.8817842 × 10*184* times the power of sunlight, and aim it at the sun and see what happens.
Put a small solar cell infront of the parabolic mirror, see how close to the focal point You can get the solar cell to the focal point before it fails.
You could use one of those small $5.00, monocrystaline solar cells from radio shack, they do about 250 ma. at about 4.8V in normal sun light, if You do then please make a video for Us. Thanks.
A MULTI-PARABOLA DISH COULD CREATE THE PARABOLIC DISH MULTIPLIER THAT WOULD ACTUALLY BE TOO DANGEROUS TO STAND IN FRONT OF Like the Frisnelle lens only in circular pieces at varying daimeters.. Focused mirror rings inside more focused mirror rings. The bigger, the hotter and the more rings, the hotter, faster..
The welder's glasses are EXTREMELY necessary! I made the stupid mistake of trying to toast a bit of white bread using a massive fresnel lens and was looking at the bread trying to establish if it was toasting or not. After about 30 seconds it did finally brown up but when I looked away my vision was massively impacted! There was a central patch that where everything I looked at was brownish tinged. It was freaky! Fortunately my vision returned to normal a few minutes later but it was scary! -S
Kinda scares me that you're making hand gestures in front of the area of the mirror that was easily able to burn that stick several times, especially with no protection.
I was thinking right, parabolic mirrors are somewhat expensive right? Because of their weird shape. What if you make your own mirror? Like the thing you need is just a parabolic glass silvernitrate and some other chemicals to make a silver mirror with high reflection. Or do you think this is as expensive?
could this be used for a telescope? im trying to build a massive mirror without paying massive prices. is there a way to make mirrors with different focal lengths?
If you want to make one with a better surface, use silver mirror mylar, house it on a an airtight box with a open hold down ring and draw a slight vaccum on it to vary the focal length. I was doing it with a piece of 1/4 inch tubing from the back with one end in my mouth and starting 2 x 4's on fire from 20 feet away! about 24" or 30"
Are you saying the Mylar is being contorted via Vacume, and thereby changing the focal Point? Or Are You saying a clear covering with a gap between the surface of the dish?
I have seen how powerful they can be, The way I have looked at it is that a filter between the sun could control the output heat. I have seen how water vapor can change the focal point.
you can,you point it at your water heater and walla scalding hotness.I cook food,like marshmellows and such.You point the parabolical lens at your torso and it keeps u nice and toasty
If you were to put something besides wood out there when the light focuses that burns, would that burn too? I've noticed that this video lasts four minutes and forty-eight seconds.
where can i get a useless dish parabolic for free? to build this concentrator, and the reflecting surface can be of paper for gifts? because there are some layer for gifts that are totally reflecting
In 1980 I saw a mirror just like this one and I accidently passed my hand through the focal point....and.....BOY...I never saw my hand move so quick, before or since!!!
I had a "picture" of the Sun burned on to my hand. OUCH!!!!
Cool, but you said something about double the heat at the end.
Doesn't the lense redirect the sunlight into a spot so how can you use the parabola mirror behind it? please explain, as I have problem picturing this!
"Hmmmm that must be USA - and FLUID ounces - and it's 29.57 milliliters to an ounce - that's close enough to about 30 milliliters, which is almost 340 milliliters."
95% of the worlds population assumes:
Most Americans are backward and stupid.
Why they don't even LIST the equivalent measurement - the we the 95% of the rest of the worlds population actually use.
So is this what you do with your measly existence? Make videos and post comments about the US? Is that all you have going for yourself? Pity. If anyone wants to see backward and stupid, check out "callmeshane303" gay videos. From what it appears in your video, it looks like you are living in your parents basement and weigh about 300 pounds...I mean 120 kilograms. You are an embarrassment to Australia.
Hmm in a nation addicted to food, sex, drugs, gossip, with a media filled with idiots, and they are the worlds worst polluters, and their corporations create enough poisons, germs and nukes to kill the global population 10X over, The US foreign debt is astronomical, ummm the health care system is up shit creek, the last president was a drug fucked idiot, the corporations are filled with thieves, the CIA is the worlds biggest drug runners,
I was born in the USA and Shane is pretty much right.....especially when we had Bush, BY FAR THE WORSE PRESIDENT EVER, and his Evil, Greedy Cronies sure gave the USA a very bad name throughout the world. We are the most hated people and nation on Earth.
Obviously Shane, we over estimate your ability to use a calculator. In future hopefully all Americans will take your limitations into account when posting information that might require mental effort on your part. I might alternately mention the 95% that use metrics do the same to the US so I really don't see the problem since we simply do the math instead of bitch about it.
Come on guys :) Who are those mythbusters? What they prove that is the uniqe and only truth? :) Great guys but even if they failed that experiment that doesen't means to me that it's impossible. (I saw that sereies)
It would be hot at the focal point, but the target would have to stay there until it absorbs enough energy to combust. Flaming arrows are much easier and less weather dependent.
We have done the deathray test and will have a video soon. Mythbusters missed one easy step. We can burn stuff at 30M with 5 regular .7M x .7M mirrors almost instantly.
To make continuous use of a parabolic reflector to, say heat water or generate steam... do you need really critical sun tracking? That would make this a daunting more task. It burns sticks good, though!
callmeshane303 u are such an arrogant prick. I just wanted you to know this and I will not be responding to your arrogant rants. I already know what you are going to say so whateve you say just know I already know what you are going to say. Every single comment you have made have been arrogant which puts other people down. Good job at life.
Shane, you're an idiot. There is precious little that will change the fact that you are a waste of perfectly good carbon that would be of more use if it were charcoal. As for exporting technology globally, I am not very partial to a great many of the places it might go... so I really don't care if you can't grasp anything troll.
Sell these things in home depot. that way campers dont have to waste time making a fire in the forest to roast marshmallow (and ...less forest fires perhaps, of course, See, thinking green =B )
May i ask a question? At the end where you reflect the light onto the building, we see dark blotches as the mirror is moved around. what are they? are they patches of the clouds above projected? trees obstructing the light? or perhaps the lens imperfections? peace:P
lol rogelio67 , like to see your matches or other materials used ; boil a gallon of water and create no pollution in the proccess :) i know your only kiddin. peace :P
I read back several pages and didn't come across my question. Something that you state in the vid that simply makes no sense.
You say you can use a Fresnel AND your parabolic AT THE SAME TIME. (I assume you mean on the same focal point.)
How? since you have to be 'downstream' of the light that the Fresnel has already re-directed the light and is no longer parallel for the parabolic to focus.
I was going to "slow cook it" inside a large 48" parabolic (heres where your going to laugh) sled saucer(the smooth steel ones they sell)BTW do I have to drill a hole in the center so it doesnt bow funny?
Radio shack used to sell small versions of these as cigarrette lighters. I wanted a refund, cuz the fine print didnt say it wouldnt light on a cloudy day lol.
They have these in a testing facility in Arizona. They are directed at ceramic pipes filled with water which is heated by these mirrors (or one like it). The steam produced in the pipes is then used to turn a turbine making electricity. Not sure of the power produced (Think its enough to power a small building) Not sure what they do when it gets dark though...
Because his arm in not at the focal point where the stick is; his arm is off top the side of the focal point. It's a parabolic dis not a parabolic trough.
OK OK OK.......show us what can be done with the mirror to create energy! I watched a five minute video of you burning sticks. You showed us every angle of that stick being toasted. Your like a kid with matches here. I got the point after the first burn.
having you point out how to see the focusing point with the smoke is awsome. watched all your vids. great work, cause, and edit. personality goes perfectly green. 5*'s
I watched a program on PBS where they used a hundred parabolic mirrors all focusing on one area, it generated over six thousand degrees and they demonstrated it by cutting a large "I" beam like it was butter.
Did you mean frensel lenses? If not, that would be some crazy heat. Also, where can I get one of these and how much does it cost? I want to get one so I can shine it at cars on the freeway. Or test the frensel combo to super heat oil to in turn boil water for steam generators.
I dont know man, but these people always keep burning sticks in their videos. I like energy alternatives as well but it would be more helpful if these mirrors or wind or solar panels are more practical to our everyday life.
Where there is fire there is energy. The stick burning demonstrates the basics and you can use some creativity from there. If you heat food, there is one aspect. Check out our other videos, there are a lot of practical applications.
yes but you can show what you can do with it? I mean the show is called green science and all you show here is how to use sun to burn down forests. use the heat for something !
I'll second you on that! Even before I saw your comment I was thinking...greenpowerscience...and then all he's doing in this video is burning wood and producing unnecessary CO2...
Go to my channel, you will see Stirling engines, Steam engines, was of bumping up pv, solar cooking videos. This video is an introductory process to an item that was only available to people spending thousands of dollars.
Focus on this, where there is concentrated heat from the sun, there is renewable energy.
Very interesting this experiment. What sort of air temperature was it at the time?, with 2-3 of these attached to a 'tracking' frame could really produce some useful energy i would think!.
So, one could boil water at that point that would travel into pipes networked under the floor of ones house. It may not work on cloudy days, but at least you wouldn't need gas/electric heat during sunny days, which, if everyone did it, would add up to a lot of savings. Yes?
i watch allot of your vids. i also have used wood for heat for 2+ years. please take a piece of non charred wood and show how long it takes to catch fire. i ask this for two reasons. 1. something that was on fire will catch much faster the second time. 2. just re-lighting a piece of charred pine does not seem like an accurate depiction of the power of the lens you describe. thanks!
i have watched your vids. Please show how long it takes to ignite a piece of wood that has not previously been on fire. moving from one area on a stick to another area is not the same as creating the initial combustion. i am sorry but it takes away from the demonstration. Thank you with most respect. corey
5 stars dan! keep it up. Hay use that new dish to try the exp again with the moon light and see if you are able to concentrate any more moon light with this dish then the other one you used. larry
um mister rojas, could you please show us how to make or obtain a good functional parabolic mirror or a fresnel lense? it just seems that your videos are mostly for demonstration.
Nice video, I hope to see you using this to power a stirling engine like your video I think that had a fresnel lens heating a metal pipe. Then the pipe was attached to a stirling. On that note, I just recently bought a sterling engine kit that supposedly runs on the heat of your hand. I'll try and record myself building it and post some videos when I'm done. Keep the videos coming.

I read back several pages and didn't come across my question. Something that you state in the vid that simply makes no sense.
You say you can use a Fresnel AND your parabolic AT THE SAME TIME. (I assume you mean on the same focal point.)
How? since you have to be 'downstream' of the light that the Fresnel has already re-directed the light and is no longer parallel for the parabolic to focus.
EXPLAIN...

Amazing things are being done with these. I understand there are companies heating water in boilers large scale in sunny areas.

Would a colored plexiglass mirror be ok? I'm bidding on a purple tinged plexiglass mirror for pretty cheap.
pipersmitty87 3 years ago
Yes The power will depend on the darkness of the color but it should work. Are you molding it or is it already curved.

I was going to "slow cook it" inside a large 48" parabolic (heres where your going to laugh) sled saucer(the smooth steel ones they sell)BTW do I have to drill a hole in the center so it doesnt bow funny?

I meant 28"

Fun - but my mirror is six feet in diameter and -kapow! yeah, wood burns.
I used an old yard style sat dish, cut mirrors in one inch square tiles and tiled interior with silicone adhesive sealant for adhesive.
silicone is waterproof, frost proof and heat proof as well as commonly available.
PAINT BACK SIDE OF MIRROR WITH EPOXY PAINT AND LOSS OF COATING WILL BE PREVENTED. Prior to gluing the tiles down, natch.
Had one that was 11 feet diameter. Flash cooked a frozen hotdog in fifteen seconds.

Silver is the most reflective, but expensive.

virusjoe101 3 years ago
They have these in a testing facility in Arizona. They are directed at ceramic pipes filled with water which is heated by these mirrors (or one like it). The steam produced in the pipes is then used to turn a turbine making electricity. Not sure of the power produced (Think its enough to power a small building) Not sure what they do when it gets dark though...

this looks fake. if it burns the stick why isn't it burning his arm lol

Because his arm in not at the focal point where the stick is; his arm is off top the side of the focal point. It's a parabolic dis not a parabolic trough.

OK OK OK.......show us what can be done with the mirror to create energy! I watched a five minute video of you burning sticks. You showed us every angle of that stick being toasted. Your like a kid with matches here. I got the point after the first burn.

having you point out how to see the focusing point with the smoke is awsome. watched all your vids. great work, cause, and edit. personality goes perfectly green. 5*'s

I watched a program on PBS where they used a hundred parabolic mirrors all focusing on one area, it generated over six thousand degrees and they demonstrated it by cutting a large "I" beam like it was butter.

Did you mean frensel lenses? If not, that would be some crazy heat. Also, where can I get one of these and how much does it cost? I want to get one so I can shine it at cars on the freeway. Or test the frensel combo to super heat oil to in turn boil water for steam generators.

I dont know man, but these people always keep burning sticks in their videos. I like energy alternatives as well but it would be more helpful if these mirrors or wind or solar panels are more practical to our everyday life.
mozung 3 years ago
Where there is fire there is energy. The stick burning demonstrates the basics and you can use some creativity from there. If you heat food, there is one aspect. Check out our other videos, there are a lot of practical applications.
Thank for the comment.

yes but you can show what you can do with it? I mean the show is called green science and all you show here is how to use sun to burn down forests. use the heat for something !

Go to my channel, you will see Stirling engines, Steam engines, was of bumping up pv, solar cooking videos. This video is an introductory process to an item that was only available to people spending thousands of dollars.
Focus on this, where there is concentrated heat from the sun, there is renewable energy.
GREENPOWERSCIENCE 3 years ago
Very interesting this experiment. What sort of air temperature was it at the time?, with 2-3 of these attached to a 'tracking' frame could really produce some useful energy i would think!.
wind4watts 3 years ago
Hi,
It was about 85F out. The outside temperature is not a factor to ignition. It only matters with build temperatures due to heat leaching.
GREENPOWERSCIENCE 3 years ago
So, one could boil water at that point that would travel into pipes networked under the floor of ones house. It may not work on cloudy days, but at least you wouldn't need gas/electric heat during sunny days, which, if everyone did it, would add up to a lot of savings. Yes?

i watch allot of your vids. i also have used wood for heat for 2+ years. please take a piece of non charred wood and show how long it takes to catch fire. i ask this for two reasons. 1. something that was on fire will catch much faster the second time. 2. just re-lighting a piece of charred pine does not seem like an accurate depiction of the power of the lens you describe. thanks!
coreymon77 3 years ago
Watch 3:15 - 3:30 the beam is moved across non-exposed pine. The section that is ignited is new.
GREENPOWERSCIENCE 3 years ago
i have watched your vids. Please show how long it takes to ignite a piece of wood that has not previously been on fire. moving from one area on a stick to another area is not the same as creating the initial combustion. i am sorry but it takes away from the demonstration. Thank you with most respect. corey

if you have a hole in the bottom you can extend an instruments thru the hole out to focal point... the hole has hardly any effect on power...

Nice video, I hope to see you using this to power a stirling engine like your video I think that had a fresnel lens heating a metal pipe. Then the pipe was attached to a stirling. On that note, I just recently bought a sterling engine kit that supposedly runs on the heat of your hand. I'll try and record myself building it and post some videos when I'm done. Keep the videos coming.
