FRESNEL LENS 2 SUN COLLECTOR Melting steel with solar power

[PigsCanFly99]

have a small'ish graphite (black) crucible. Get the large, light-weight mylar mirror out of a rear-projection T.V. Reflect the high-noon sun into the horizontal. Employ a fresnel lens to heat the face of the crucible. Use two mirrors and two lenses - come in from either side. Wear brazing glasses - get to see what you're doing.

[PigsCanFly99]

heat the ceramic substrate (black) till it's cosmically hot .. then move the zinc over it.

A graphite boat might be the best answer .. you're always going to have to contend with the reflectivity issue. I say best to heat the vessel. Be good if you could reflect the light at a 90 somehow .. come in from the side. Employ a plurality of magnifying lenses - Fresnel or otherwise.

new way of fast cooking? LOL

[schnuteye]

melting Zinc and melting Steel- any alloys is about a TWOTHOUSAND degree Fahrenheit difference. this video is not properly named for starters.

[AManOfHope]

Have you ever tried putting it into a mold of some kind? Or made simple items with it?

[GREENPOWERSCIENCE]

I have an art video for a Berlin Wall project I did in 2008. I will post soon. Zinc is a GREAT low temp petal for molding.

[AManOfHope]

@GREENPOWERSCIENCE Awesome! I would like to see it. Eventualy I want to set something like this up. Keep up the good work you've got a lot of people thinking!

[ecomunky]

how about a mirror under the pan

[sciencenerd1616]

6:30 oh fuck

[ItzEddie]

loool

[Pandaasian]

this takes killing ants to a whole nother level. lol

[YairGeva7]

congarts, you made fish gravy.

[levlobotomy]

zinc has a low melting temperature

[brt5470]

6:30, hahah why did you touch it

[Th33k]

lol green energy...you just have fun melting stuff dont you? xD

[felixthemaster1]

i feel like just brabbing it and just playing with that putty like texture

[oarahman]

You've got mirrors...use them! Bounce the light under the pan and cook normally. Maybe freshnel to parabolic under pan?

In any case....very cool!

[joelito101]

Keep up the good work, did you have to weak any protective gear for cooking with this much energy intensity?

[exevez]

thats prety cool seeing as u dont even have the light at its smallest point. for the video you should have done it at the fastest you could.

[pvampire]

I make jewlry..would this be an good way to melt small amounts of gold and silver to cast? What would be the smallest lens I would need to do pieces that weigh like say 5 grams?

[GREENPOWERSCIENCE]

You would need a Spot lens, 33" X 44" (CORNER TO CORNER 55" MODEL) for 5 grams, also a small crucible to keep wind off and heat in. The reason you need so much extra power with gold and silver, other than the higher melting temperatures is the shiny quality. Much light is reflected so you have to gain as much as possible above their melting points.

[joelito101]

Could you heat up a container made out of stone, so the heat transfers directly to the shiny metal?

[lavell12]

yea, melted butter does tend to get a little warm. touching it isnt the best idea, haha

[social3ngin33rin]

That's a very scary lens!!!!

[ieatiron]

are you melting steel or making fish sticks?

[Sonyoooo3]

Maybe?

But for baking bread are also nice this will a bakery allot of money but the bakery needs sun then you can save money if i where the bakery ill move to Egypt desert maybe there he will save allot of money?

[Sonyoooo3]

If this ray/light from the solar lens cannot make hole through potery?

Then people have a way of cooking food with by the use of solar lens.

[RizzoLove]

At what point did you melt "steel?"

[builderofstuff]

ditto. the zinc is an extremely low melting temp metal, far far below steel, and from what I saw the zinc never even got hot enough to pour into something useful.

[RaspWillow]

yes, it's not at all impressive that any normally solid metal was turned to liquid using only rippled acrylic sheet

[KEngel1021]

The melting point of Zinc is 788 degrees Farenheit. The melting point of Iron is 2800 degrees Farenheit.

[killofthequeen2]

at the beginning i think.

[CAJAGI84]

Quiz:How to torment Terminator T1000 ? ROFL =D

[roidroid]

a reflective spatula eh

[samjones007]

lol @ when you stick your hand under it and scream "OW F**k"

[bitRAKE]

Got to love cast iron skillets.

[mclorkus]

Very cool, might bid on your auction, It is sort of funny you put not a toy in the auction but have "Water dancing on Zinc" in this movie. :-)
