God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

I love how you provide historical context, especially on those messy years where science wasn´t still consolidated

[@janhemmer8181]

I think science is never consolidated. Then it would be indistinguishable from religion. What i like about this young mans video's is the spirit of discovery in the forming years of what is now called modern science. That is the spirit that will hopefully never stop. Nowadays it is needed more than ever, since there has not been real progress for more than half a century. This channel gives me some hope of what may be a New Renaissance! Keep up the good works.

[@TheZombieSaints]

I made a one of these using a big fresnel lens out of an old rear projection TV. It's could liquify the brass of a padlock and turn most rocks into lava. Sunlight has SO much energy in it! Great video.

[@blueredbrick]

Did you also notice that it makes a difference which side of the Fresnel lens you let the Sun light through? (I mean the amount of light that gets through and therefore the burning power or quickness to set wood on fire) I forgot which side worked better; the smooth plane facing the sun or the ridged plane facing the sun. There was no apparent anti reflection coating on either side in my case. Can you remember which side worked best?, the lens got lost during moving to another house :( The mirror that was used in the TV projector system was also quite interesting and was a super efficiënt: mirror mylar (I think) foil that was framed sturdyly and it was a type of mirror that has the metal surface bare, so I guess some aluminium or tin (?). The surface was easily damaged..

[@Satryn]

The ridged plane facing the sun works best

[@fraserbuilds]

😅what can I say I use what I have

[@typha]

2:04 By the way, the s in "Fresnel " is sort of silent (technically it modifies the pronunciation of the "e" slightly). There was a period of time when old french had a lot of es's in it, but they all got swapped out with "é" except it would seem in some names where the spelling didn't change but the pronunciation did.

[@sansprobus7209]

It's basically pronounced Fr-eh-nell.

[@MADmosche]

Glad someone called this out. It bugs the heck out of me hearing “fres-null”

[@persephoneblack888]

[@fasted8468]

If you take chalk and charcoal and mix them into a powder, put under a solar lens, you can make calcium carbide, and them acetylene very easily

[@jercos]

2,200 °C would be quite an achievement with this little lens... a quick search shows successful attempts in open air with ~2kW of power (and almost 40% losses), with peak solar irradiance at earth's surface near the equator only around 500 watts per square meter.

[@putteslaintxtbks5166]

It would probably work well if you make a small box out of fire brick or rock wool, etc. to hold the heat and with a small hole to let the light in through. I've thought about making g a microwave kilm and You Tube has videos of making them, only a hole to let the light in would need be added.

[@pierluigirizza2140]

It is funny to think that this object dates way earlier than 15th century and was used for completely different reasons. I’m from Siracusa in Sicily, where Archimede was born. In my school there is a big statue of Archimede standing next to a huge piece of round glass (like the one you created). From a young age we were told many legends on Archimede. According to one of them, it was said that Archimede used the lens -and also some giants mirrors-to burn the enemy ships.

i think the most interesting part of solar furnaces and stuff like that is that its literally just the sun and nothing else the amount of energy that the sun dumps into the floor over a square foot or so is enough to melt metals

[@joaomrtins]

Some good historic beats missing are: Newtown development of the telescope which led to the biggest optical apparatus humanity ever built. The creation of the Fresnel lens. If your creation used a regular lens it would be far bulker. But these are more well known than the facts presented and the video would run the risk of getting too long.

[@sanuelkessler8435]

You are living my dream, sir! Constant "Eureka!" moments like this video will always keep me coming back for more! I have a lens from an old box tv that should perform relatively in the same manner as yours. I watched the king of random make one from the tv a long time ago.
