This is on of our new 55.7″ Paraboloids that produces almost 2K of solar power. They are beasts when it comes to solar heating. I hope to do videos with Steam and Stirling Engines to provide a working model that actually can be used to produce some power. These boil 12 oz of water in under a minute. Still testing and will have videos on that soon. Please Rate this video and subscribe to our channel.

How optically accurate are those? Build a fking telescope out of them
.
stupid n00b u know nothing its the same trust me
it oviusly has to be a parabolic mirror you dumbcunt
buy a mirror u fag thats the same efect
I saw a similar setup on a solar cooking website. The solar oven was rotated by a motor powered by solar cells. That setup also used photoreistors. Although if I remember right, it didn’t use a comparator. It just had a thing to shade the photoresistor when the oven was pointing at the sun. Sun moves, light hits photocell, resistance on photocell goes down, motor fires up, oven turns to face sun, photocell is shaded, motor stops. Very cool idea.
Can you make french-fries with it?
that depends on distance between him and the focul point, where the beams are concentrated
Find or buy a 3 meter Motorized Satellite Dish and stick small mirrors to its surface . Google “Red Rock Energy Heliostats” and click on “LED3X Solar Tracker” to find diagram to build cheap solar tracker that controls satellite dish actuators to point dish to sun. You might even be able use the hot water from the solar dish to power an absorption chiller pulled from a propane fridge for air conditioning etc.

how do i make one? where can i buy one?
lol it would have been funny if the camera man caught on fire while walking in front of all those mirrors
A focal point is the hot spot where the dish combines its reflection. Since it is Receiving sunlight, I am sure you can stand in front of these with no problem. It is that golfball sized spot known as the FP where you would get fried. He mentioned where the FP is and as you can see it is very shallow to the dish, in other words, very safe to use.
This is a great idea but keeping the dish shiny is essential!
So how do i build one? hehe
of course. you would have to be unlucky but is that a chance you want to take with children..
That would be under the assumption that all the light is being focused directly into your eyes, which is what happens when you look at the sun through binoculars.
but it would be. it would be less than a second and possibly much less if they are pointed at the sun.
you may have heard that you shouldn’t look at the sun through binoculars and that’s a golf ball size area of light gathering. that dish is around 650 times bigger. you wont know what hit you
I doubt it would be immediate.
very good slightly helpful.
It depends on the size of the mirror… maybe you’d just get hot because walking in front of a mirror means obscuring quite a big section of the mirror itself.
can i use this to light smoke?
it’s not quite that fast
only really the eyes that could be damaged instantly
Not to mention if you walked in front too close you would start burning alive.
very impressive but they are rather dangerous. a kid running up to them and looking in would lose eye sight immediately. do not leave unattended.
$9 K for all, I was transferring them for a client, they bought them. I kept 3 for research.
How much did it cost per dish and total cost for all of them. Must be lots. Dan, you win the lottery or something, lol?
