Hello Dan, I subscribed your channel and love your videos. Could you please put a candle at the focal point of one of your parabolic mirrors, at night, and show that on video? It would be fun to watch the difference between the light of the candle in or out the focal point. Thank you and congratulations! (Salvador, from Portugal)
Nice video thanks for the info.I would like to build one big enough to create rain clouds and make water for crop irrigation. I have seen the one at NASA on the discovery channel and something ten times the size mounted on a aircraft carrier might do it. Can u say purchase land in Arizona.????
These would also be great to have on roofs of buildings and use against riot police (like my ancestor Archimides did against the Roman fleet!) when they declare that your peaceful protest as "illegal" and decide to beat the sh!t out of you! But first to go should be the dish of the MRAD vehicle! For those on the ground, the parabolic shape is also great to send the MRAD sound, back to them (it's basic accoustics). Peace!
@onlinebills02 Um the focal length is only several centimeters away from the parabolic mirror. To focus heat to that great a distance would require a much larger dish; if you have a 30ft diameter dish, then it will focus heat on a spot 15 ft away.
You have discovered the speed of light. When light passes through the focal point it obviously must speed up. Only makes sence that all those photons collected in the parabola would have to travel faster through the opening. Good stuff. Let me know if you think about this stuff to. 1x the speed of light can be multiplied by the parabolic dish to 2x,3x or whatewer you want i think. But I have been wrong once before.
@61miroman You're um... completely wrong. This has nothing to do with the speed of light. Light's speed is always uniform, but this mirror works on the same principle of a magnifying glass by focusing the beams at one spot.
@b0omtown All that energy from 5 sq meters of energy 150 million kilometers away from the sun which is a star. And there are a LOT of stars in the universe which theoretically the gods created.

Communism failed because it was corrupt, but also because we bankrupted it (in Europe). Capitalism failed because yet another communist country knows how not to let divisions (such as enviro red tape and excess taxation on businesses) get in their way.
The ONLY solution is to create jobs... Then we don't have to cut services. Sure tax the rich but not the foundation to employment. That foundation is machine made solar dishes.
@moinmt what's your solution to fossil fueled depletion, huh?
It would be GREAT to "transport" light using some kind of "fiber glass/mirrors cable" from one point to the earth to the next, expanding the light at the end of the cable using some kind of complex system of mirrors again, etc.... ;)
Check out my homepage for further experiments using laser. There are several easy to do examples to split the beam, modulate on of the two and then recombine them to produce low frequency beats. These beats should be able to induce currents into the body to transmit sound or steer muscles if used with high power lasers. You dont even need a laser, this can be done with ordinary light and heat radiation as well. The double slit experiment mostly is done with an ordinary light source.
@Armornone Do some research. Most of these things in this catagorty are working. Look at Earthship houses too. Look at Earthbag houses, and soda pop heaters. You just don't take the time to really open your eyes and educate yourself. Anyway, someone MUST work on redistributing the wealth since about 2% of the world holds 95% of the wealth. Are you comfortable with that. If so, you must be very rich and so I guess I understand your fear.
@moinmt Ha! You admit it. That is called communism and green power is just a front for communism. You need to deal with it Buddy. Carbon Credits is just a way to steal money from Americans and give it to 3rd world countries. You have been exposed for this crap scam.
now... put them all in a big circle and let them point right forward and not up or down or right or left only a perfect circle then lets see what happens;)
@1950dodgefan Actually, with the right focal length (i.e. adjusting the angle of the curve), the mirrors he has NOW are almost the same size as the Solar Furnace which can melt/burn any substance known to man.
How difficult is it to change the focal length of the mirrors? I suppose it's not the easiest thing to bend glass (assuming that those mirrors are made of glass)
@abunai59 Nearly impossible, actually. You'd almost have to make new ones. If you are wanting a mirror that changes the focal length, you'd have to have made of a flexible reflective surface, rigged up with a harness which moves.
Dan, you blow me away with your random videos on solar power! I would love to see one of your solar reflectors or parabolic troughs in a steam generator setup. Every time I watch one of your videos I keep thinking "Holy crap, where does this guy get the money, supplies, and time to do all of this?!" Your work is amazing!!
Look what I'm doing with my blog using a parabolic trough and a tesla turbine. I would love to help you make something like it!! teslapower.wordpress . com
Get a spherical mirror. The mirror being on the inside. Drill a hole in it and have fiber optic cable in the hole and a prismatic lense on the end of the cable. Run that down into the middle of the sphere.
Either a very odd disco ball you shall have or who the heck knows what may happen. Would be interesting to gauge the temperature inside of it though to see if it builds up energy.
Hi Dan, I am a norwegian technology student currently working on my thesis about concentrating thermal solar energy. I am looking at small scale systems for cooking purposes, where air is the transport medium from a porous absorber to a rock bed heat storage. For this case I need a parabola with Ø~140 cm which is stiffened up by a suppert to avoid deforming. Do you know any companies manufacturing such parabolas? And where are the parabolas on your webpage manufactured?
That's right there is no way they can be combined with that short of a focal point. Unless they are focused in tandem on a long length of flat black pipe filled with water. ; )
@GerbilEssences Well, Germany's apparently working on solar banks in the Sahara and just running power lines back home. Sweet idea, if the lines can be maintained - especially since the shade under the collectors is compatible with crop-growing!
Dan you need to take that array and focus on melting salts which use gravity to drop into a bunker, to be then stored at 500+ F. Then controllably, you can use the way-above-the-temperature-of-boiling-water insulated molten salt in stainless steel vessels to power a steam engine. Not direct Stirling, not steam turbine, a steam engine. Then you'll be rocking.

@CheeseBon When it rains everyting melts and the world comes to an end, and people cry like little babies. Let me ask you, what about when something goes wrong in the middle east? What about when a nuke plant blows up? Or moutains and rivers are destroyed by coal farming. Which is worse? Why would even ask a question like 'What about when it rains?" Duh, you use your batteries that stored solar when the sun was our or you get energy from the grid. You should be ashamed for asking.
I have worked out each of these mirrors could produce 1.7kW of heat in ideal conditions. Based on a solar flux of 1000 watts per square metre of area.
Holy fuck....i wonder if this technology has been utilized in powering some kinds of UFO's. I see alot of potential in it for massive perpetual power generation.
Can some one give me some tips, first ive got a slightly oval 18" by 22'' dish to make a mirror , is the dish satellite oval dishes still a good mirror to use ? do they focus like a true parabolic mirror once linned with reflective foil ? ?
@bogardenit Hey, I am an ex-Dish tech,so I have quite a few extra dishes. Last summer my son & I decided to make one.I grabbed mirrors in peoples trash piles on garbage day and cut 1 1/2" squares& adhered them to the dish.ALOT of work and because the "tiles" I cut were not consistently the same size, the results were only fine.It burned sticks and boiled water, then I used the reflective tape for sealing duct work, NOT DUCT TAPE. This worked better than cutting the mirrors and it was easier.
@bogardenit The 18" round dishes with a single eye LNB works great.Don't expect to burn the stick in seconds though,it will take at least 20 seconds or so to get it going on a hot bright summer day.The focal point of course would be right were the eye of the LNB is,however if you use an oval dish designed for multiple satellites then the focal point would be closer to the dish.I do not believe that this gives much more focus sunlight though.Of course the bigger the dish the more sun reflection.
maybe we should reduce the demand, everything 12v or less......... alternative fuels for cooking, whatever, there are so many ways man have created light and warmth.... nuclear is getting crazy, if u can do something with one thing, u could do something similar with another, need i remind we live in an infinite universe, focus on that, not limited resources corrupted for a profit...
Have you thought of making a small planet like body on which to mount this? You could then maybe send it into close earth orbit and extract money from man kind, especially if you keep up the D E A T H R A Y angle, I like it, if you need any help with space rockets let me know.
Hey Had an Idea I saw another video about house that used a tubular collection device to gather and bring sunlight into a room through the attic. I wondered if this device could be coupled with a Fresnel lens to bring the power of the sun and the cooking power of the fresnel lens into a modern kitchen???? It is a Fresnel Type device attached to a reflective tube that runs through the attic and brings the light into the room through the ceiling supposed to give as much light as 4 100 what bulbs.
W00t for pointing the camera DIRECTLY at the reflective parabola!!!
and b4 anyone says anything about focus point and "idiot it wont burn the cam" i know, it is well away from the focus point, and the light has scattered enuff to be like looking directly at the sun, unfocused
Where do you get mirrors like those? or how do you make them if you do? i saw you video of a small mirror you made in the oven. do you use the same concept for a big mirror?
fck, now i gotta search for 1950dodgefan

@CheeseBon When it rains everyting melts and the world comes to an end, and people cry like little babies. Let me ask you, what about when something goes wrong in the middle east? What about when a nuke plant blows up? Or moutains and rivers are destroyed by coal farming. Which is worse? Why would even ask a question like 'What about when it rains?" Duh, you use your batteries that stored solar when the sun was our or you get energy from the grid. You should be ashamed for asking.

Oh also worked out that will produce 16kg of steam per hour at 100 deg "C" constant draw off.

I have worked out each of these mirrors could produce 1.7kW of heat in ideal conditions. Based on a solar flux of 1000 watts per square metre of area.

Holy fuck....i wonder if this technology has been utilized in powering some kinds of UFO's. I see alot of potential in it for massive perpetual power generation.

Can some one give me some tips, first ive got a slightly oval 18" by 22'' dish to make a mirror , is the dish satellite oval dishes still a good mirror to use ? do they focus like a true parabolic mirror once linned with reflective foil ? ?

@bogardenit Hey, I am an ex-Dish tech,so I have quite a few extra dishes. Last summer my son & I decided to make one.I grabbed mirrors in peoples trash piles on garbage day and cut 1 1/2" squares& adhered them to the dish.ALOT of work and because the "tiles" I cut were not consistently the same size, the results were only fine.It burned sticks and boiled water, then I used the reflective tape for sealing duct work, NOT DUCT TAPE. This worked better than cutting the mirrors and it was easier.

@bogardenit The 18" round dishes with a single eye LNB works great.Don't expect to burn the stick in seconds though,it will take at least 20 seconds or so to get it going on a hot bright summer day.The focal point of course would be right were the eye of the LNB is,however if you use an oval dish designed for multiple satellites then the focal point would be closer to the dish.I do not believe that this gives much more focus sunlight though.Of course the bigger the dish the more sun reflection.

maybe we should reduce the demand, everything 12v or less......... alternative fuels for cooking, whatever, there are so many ways man have created light and warmth.... nuclear is getting crazy, if u can do something with one thing, u could do something similar with another, need i remind we live in an infinite universe, focus on that, not limited resources corrupted for a profit...

focal length of what, 4 feet? they can not focus on the same point so you can not have fun with an array of them.

Have you thought of making a small planet like body on which to mount this? You could then maybe send it into close earth orbit and extract money from man kind, especially if you keep up the D E A T H R A Y angle, I like it, if you need any help with space rockets let me know.

Hey Had an Idea I saw another video about house that used a tubular collection device to gather and bring sunlight into a room through the attic. I wondered if this device could be coupled with a Fresnel lens to bring the power of the sun and the cooking power of the fresnel lens into a modern kitchen???? It is a Fresnel Type device attached to a reflective tube that runs through the attic and brings the light into the room through the ceiling supposed to give as much light as 4 100 what bulbs.

W00t for pointing the camera DIRECTLY at the reflective parabola!!!
and b4 anyone says anything about focus point and "idiot it wont burn the cam" i know, it is well away from the focus point, and the light has scattered enuff to be like looking directly at the sun, unfocused

@SilverDHedgehog2 If it's far from focal point, then it's just a little warm to the camera.

Where do you get mirrors like those? or how do you make them if you do? i saw you video of a small mirror you made in the oven. do you use the same concept for a big mirror?
