Fused glass to steel requires annealing and a large Fresnel Lens works perfect. The use of a motorcycle jack stand acts as a perfect work bench. GREENPOWERSCIENCE.COM
GREENPOWERSCIENCE Your videos are always amazing and entertaining, Dan. 👏 There's something about this process that is very intriguing to me. Just curious, have you made any solar art nice enough to put in your home? It's so amazing as is, but I wonder if you've made anything so cool you just had to keep it as a showpiece, so to speak? If so, I wouldn't mind seeing that. Much love to you and Denise. Have a great day. 👍
WOW. Thank you so much. I made a work of art years ago on a piece of the Berlin Wall that was imported to an art group for the Holocaust Museum with images cast in zinc and "Peace" burned into the cement. I also did some zinc fish castings which I have two of. The better ones sold. Lots of glass art for gift etc. We were art curators and artists from 2000 - 2007 before GPS. Most of the art is acrylic on canvas. This video shows some of the paintings Denise and I did. ruclips.net/video/FyCLOXF1188/видео.html Art part starts at 8:40 in the video. We have a video due out soon painting with the sun burning wood. Some cool tricks to make it easy. Thank you for the great comment.
Hi Dan. Thanks for taking the time on that awesome reply! I remember that video from a few years ago and just watched it again. You and Denise are very talented artists, and I don't use those terms loosely. I love being around creative people (my wife and daughters are three of them). ;o) About 6 years ago, I did a wood-burning project for a friend who was retiring. He's a big music buff, so I made him Jimi Hendrix portrait (small scale). At the time, I was considering taking a shot at solar pyrography, but never got around to it. Your videos not only inspire, but remind me to try something new and different in the name of art and science. Very cool! I noticed in the video you linked me to, Denise (I believe it was her signature) had a beautiful Hendrix painting in front of an American flag. Spectacular artwork, guys! Keep up the awesome work and I'll check you later. BTW, congratulations on 10 very productive and inspiring years on RUclips! Cheers, Mick.
Thank you Mick. Give pyrography a shot with solar. It is one of the few solar projects that works well with small lenses like high quality page magnifiers. One trick is to use light colored material as the canvas and marker (black) in the image/detail. When the sunlight is focused on the target area, the black burns first as the light is absorbed. Solvent based markers are a plus. Would love to see some of your art. Best Regards, Dan and Denise.
Check out our new channel we are working on. ruclips.net/channel/UChxtn8BNkfSfYx_3KMfvHxw It is quick videos of Fresnel Lenses vs different objects. Any input on ideas for total destruction is appreciated!
I love the longer videos Dan, this kind of thing is fascinating. I'm looking forward to mid summer and seeing what the fresnel lens can do under the midday sun.
Thank you Green Silver. I am getting back to basics and moving away from competing with the viral channels. Tried it when YT changed their algorithm and views plummeted. I started this to share ideas and connect with awesome people, not to be a viral star. I enjoy this format so much more:-) Winter is usually when we get the best results here in Florida because of the lower humidity and less fine particulates. The advantage to summer is the sun directly overhead so I can work straight down on the target. The sun trackers also work better in the summer so adjusting is a lot easier. Thank you again for enjoying our videos.
There is a limitation due do the radius of the sun seen from the earth! The sun is no a singular point in the sky but a "wide" surface. A ray from the right edge of the sun will not converge at the same place than a ray from the left edge. The picture of the sun you can obtain has a surface which depends on the focal distance of the lens even if the lens is a perfect one. In theory, with this kind of lens we can reach 2000°C, but not more. To get more it would required a perfect lens, wide, with a tiny focal (a few inches).
I wonder if there are any forgery laws for meteorites? Joke:-) I think it would look similar. We have a 300+ pound rock (or something) that is buried in our yard. My late Father said there was a huge boom and he saw a crater with a smoldering rock inside. The crater is now a pond in our swamp area of our property. I was 5 years old at the time visiting family in Texas with my Mom for New Years. This rock was moved around our property for years (required 5 people) and would always sink in the dirt. The final resting place is near our pond (man made, different from the crater pond) and is now fully buried from gravity and embedded with roots from plants. It is orange and has many holes like swiss cheese. The mass partially responds to a metal detector but is not magnetic. Samples from the mass ground into sand are 100% magnetic. Thinking of digging this think up but worry about breaking it. My Dad was not really one for expanding on the truth. Dimensions are roughly 1M sq. That is assuming it can be excavated in one piece. Since I am far from an expert on meteorites any ideas or thoughts would be helpful. This could be just a crappy rock or…….?
Awesome, Dan. :D It's really cool seeing the chromatic dispersion from the lens. I'm curious how you film the ultra bright focal point when you're melting things... do you use a stack of ND filters on the camera?
Built in ND, F/stop max, 1/10,000 of a second shutter and ISO 100. We have had film crews here with high speed and they need to close down to max. In older videos with our first camera I converted a torch goggle to a filter. You really need manual control as Auto just goes nuts. When filming, I usually need to constantly adjust. If glass reflects directly at the camera nothing is visible. Smaller low powered lenses are easy but the big ones are extremely bright at the focal point. I have eye protection on but usually just use the clear eyewear when working with a video and use the viewfinder of a mirror less camera.
It is amazing. When I got my first really good lens years ago I focused it across the ground and the sand instantly started popping and melting. I had played with page magnifiers before that. Totally different experience.
I dont know if you are still responding to comments on this video or not. But I am looking for a specific application to super heat a 12 inch circle of frozen ground. Wondering if its possible? and what would you recommend to do this?
We use the inexpensive green torch goggles with flip lenses. They are not as dark as a welding helmet so you can see what you are doing away from the focal point. Too dark and you can knock stuff over etc. I spend a majority of the time shooting videos looking through the viewfinder of the camera to adjust the exposure which can radically change by moving the object I am working on. When I do that, just clear safety goggles. The camera is a mirror less so basically looking at a small TV screen. This is also why you sometimes hear me breathing. Stretching arm way out while looking through the camera. Working upwind is a good idea too. Sometimes I hold my breath for a minute or so if the wind changes directions. The goggles are on our website for $5 but Harbor Freight sells them too for about the same price. They look like this: greenpowerscience.com/FRESNELSHOP/GREENGOGGLES.html They are made cheaply but the only thing I have found over the years that provides protection without being too dark. The flip up is helpful too.
I am curious the same thing. Would it increase light to a panel without destroying the panel? I have an idea to help control temperature of the panels if too much heat was a problem. Imagine double or even tripling a single panels power output.
It is viewable with goggles and occasionally with naked eye. The camera is stopped down fully and maximum shutter speed at lowest ASA. The only filter is the ND.
This lens is on our website greenpowerscience.com and is equal to the 49" Spot. I usually use the ones with imperfections for our videos as they work the same as a mint lens.
That's what I was thinking. I wonder if it's possible to get a homogeneous mix of the two, and what properties that might have, but I doubt that he has the tools to do something so complicated and maybe even dangerous, and especially by just using a Fresnel lens. To do it right, I think that you'd have to have a heater heat everything at once, and then mix everything together like you're cooking, and then cool it all in a very controlled manner, slow manner. It sounds like an expensive process, to me.
I have mixed it completely and the glass was conductive, magnetic and solid black. Because I started with screws vs a metal powder I am pretty sure they mixed. It shattered 2 hours after casting so the annealing process was not done correctly or it may not be possible to hold large shapes. I will revisit with a video when we get some sun and the wind settles down. I crushed the broken pieces into a powder and almost everything was picked up by a magnet. The only pieces that did not attract were blue glass from the blue beer bottle I used. So that part did not mix but 90%+ was magnetic.
In theory yes. But to form it right would be very difficult. You can would have to melt like 2 litres of glass, then pour it into a fireproof lens form. Then sand and polish it.
Dan... Have you ever tried to melt case hardened steel? ie: socket, wrench or bolt. I saw the phone melt you did. I believe the melt case was made of, what we call, aircraft aluminum. Very hard and high tempter melt point.
That phone is on my to do list:-) Totally surprised me how resistant it was. I have melted a bolt and nut together years ago in one of the older videos. When the lens array is completed it should be no problem. This should also help with larger masses of steel. I want to weld something larger than screws and saw blades together. The issue with wrenches and bolts is the shiny surface. A lot of people see the lock melting video. The padlock body is easy, especially on a very small lock. The shackle on a high quality lock that is larger than 3/16" diameter is tough. I will see about all these items soon:-) Thank you for the comment.
Hello Dan. I have watched many of your videos and learned a lot from you. I have an idea to maximize solar panel efficiency but could use some tips. I would like to make my idea a reality but I am not very familiar with solar technology. My idea would be nothing without the help of your videos that is why I am turning to you for direction. Maybe you could leave an email address so we can talk in more detail? Thanks and have a great day

First long relaxing work video in a few years. Nice to just share work methods without trying to stuff it under 3 minutes.

And just imagine that this is ONLY from a FEW FEET WIDE and LONG LENSES! Long time fan of your channel. Subscribed. And shared it on other platforms.
Good stuff Dan. Forgive me for laughing when you burned yourself. lol. Happens to me every time too. They'll get'cha!

pretty cool vid Dan , its always cool watching metal and glass just melting together like that , really incredible !!

I would love to see one of those glass/metal art objects cut in half and polished, maybe it will look like a pallasite.

Dan, do you have any experience with UL 1741 inverters to sell back to the grid?
Awesome, Dan. :D It's really cool seeing the chromatic dispersion from the lens. I'm curious how you film the ultra bright focal point when you're melting things... do you use a stack of ND filters on the camera?

For all the times I have seen this type of demonstration, I am still amazed how much solar energy can be gathered from a 3 foot by 3 foot area.
It is amazing. When I got my first really good lens years ago I focused it across the ground and the sand instantly started popping and melting. I had played with page magnifiers before that. Totally different experience.
Nice, he melted a rock and made lava
What kind of light that gives this temperature as it shows dark area
What do you use to protect your eyes and the camera sensor?
got to start forging. hammer out some blades or art work?
Hi there....I was wondering.....can I reach 1000 celsius degres using this lens ??? I'm intrested.
What appening when you place a loup lens one a sun ray convergence ? And with a succession of lens ? Thanks for your knowledge...
I dont know if you are still responding to comments on this video or not. But I am looking for a specific application to super heat a 12 inch circle of frozen ground. Wondering if its possible? and what would you recommend to do this?
Where did you get your infrared heat gun?
Love your videos! Thanks. :-)
Thank you Les!
So why are we burning oil and coal?
Very well said mate 😂
Transparent aluminum ?
lol metal and glass sculpturing very nice.
gee wiz, didn't expect it to melt granite
Do you need eye protection beyond safety glasses? Like a welders mask or something similar? Or is it safe with just standard safety glasses?
We use the inexpensive green torch goggles with flip lenses. They are not as dark as a welding helmet so you can see what you are doing away from the focal point.

Thanks for the reply. Just did a quick google search on it. I'll be buying a pair of those. Awesome vids, been subscribed since 2013 I think.
with wide focal points, would this help power a solar panel?
I am curious the same thing. Would it increase light to a panel without destroying the panel? I have an idea to help control temperature of the panels if too much heat was a problem. Imagine double or even tripling a single panels power output.
are you able to see the colour spectrum in real light or is is it too bright without camera filter?
It is viewable with goggles and occasionally with naked eye. The camera is stopped down fully and maximum shutter speed at lowest ASA. The only filter is the ND.
Very very nice :-) what is the price for this kind of lens?
This lens is on our website greenpowerscience.com and is equal to the 49" Spot. I usually use the ones with imperfections for our videos as they work the same as a mint lens.
What exactly are you making here? Fumes?
Only real fumes are from the oil on the screws and the plastic seal on the bottle top.
This is your brain on TV
Very cool dan! Or should I say HOT!!!!
could you actually make a glass-metal "alloy"? it looks like they are flowing together rather nicely!
That's what I was thinking. I wonder if it's possible to get a homogeneous mix of the two, and what properties that might have, but I doubt that he has the tools to do something so complicated and maybe even dangerous, and especially by just using a Fresnel lens.

GREENPOWERSCIENCE it snapped because of the different thermal characteristics. Use an even slower and more controlled.
Gotta keep them as close to what they can handle each other on the way down.
Can u melt glass into a magnifying lens..then burn with that?
In theory yes. But to form it right would be very difficult. You can would have to melt like 2 litres of glass, then pour it into a fireproof lens form. Then sand and polish it.
Dan, have you given any thought to the project I mentioned to you?
Need to sand and grind it. Into a spheroid then polish the outside.
That sounds awesome. I have borosilicate which might survive that process better than soda glass. Thank you for the idea!
gotta keep them from breaking each other when cooling them down. keep them the same temperature while still slighty reducing for as long as you can.

What you're thinking of is called CPV (concentrated photovoltaic).
