real nice equation too bad we don't know the what the varibles stand for!

@Ryboy1381 What did they do?

[kennethvanhorn]

here is the way you can use what you made. send the sun light into a cone shape focal point into mirrored tubing and send that sun light down into a mirrored box where solar panels would be spinning to keep the solar panels cool or put in a cooling system but i think that will be a problem control the sun and make it work for you dish has to have robot arm to follow the suns path

48.96 inches! :)

@Ryboy1381 i know i was joking to but lets point one at each country and end world starvation by cooking hot dogs so it two birds killed wid one stone

[strangefire97]

@Ryboy1381 and you should fuck your self racist bastard

[gooddarkjedi]

soldire: arkimedes, the romans are attacking. arkimedes: exelent, now preapare my death beam so i can fire my lazor. soldier: but sir, the sun is in the clouds. arkimedes: FFFFFFFFFFFFUUUUUUUUUUUUUUUUUU­UUUUUU

122 inches... thats what she said....

"The "Also Sprach Zarathustra" was and outstanding choice for soundtrack.

I'm old school, so I would also use Corningware and Pyrex to create a solar cell capable of replacing grid technology. Sorry, weapons are not my thing.

lol silvax

could be bigger :/

hey!!! i thought ur going to burn something come on!!!!  >:O

Hey, nice job. In case your interested, I have seen this material for making parabolic mirrors. It is kinda like Mylar, but more reflective and has adhesive backing. Anyways, you can check it out here:

It might be easier then all those little pieces, and make a better mirror. In case you decide to do the project again.

Anyways, nice dish. I like how massive it is.

[aguirreruru]

what are you saying... mythbusters???

[pingpong1525]

"Ancient Greeks were far more techy than your teachers/professors will admit"...I disagree...If anything, teachers stress the advancements that the Greeks, Romans, Egyptians, etc. made through the years which is the main reason why they are still referenced 2-4,000 years later. And yes, obviously they used different technology than in this experiment, but we had to keep to a very strict school budget and were teaching the math behind it and not trying to re-create the Archimedes myth.

[nepalihercules]

it is believed that the anicient egyptians, romanas and the greeks were taught by our future generations who went back in time and taught them all the stuffs. u can take pyramids size and the mathematical accuracy for example

[Ledamonster]

@pingpong1525 Well... If it werent for the Inquisition... we'd be a WHOLE lot farther in technology now. Thousands of years ago there was the Baghdad battery, coin machines... ancient industrial plants, inside heating and cooling... elevators, powered doors... and who knew? Yes the Greeks were far more techy and why is because of HOW they think about things. Sort of like it took thousands of years to figure out how the Egyptians built pyramids because they used ancient not modern technology

[jfnelson77]

@Ledamonster You can't railroad until it time to railroad. Old saying. The only reason we had the industrial revolution was because of the Black Plague. It killed a lot of people. People inherited the goods of others and were there fore rich. So they took the water wheel from the Romans and from there starts our history.

People have always been smart. But there was no need to apply it.

[RlCHART]

@Ledamonster yea like technology is really making this world a better place...

[RlCHART]

@pingpong1525 this can be done very cheaply. It has nothing to do with budgeting; thats only a cop out for lazy teachers who care more about their pockets than their teaching.. these types of "recreations" are indeed very helpful in the applied and empirical sciences.

[camlpg]

If the focal point is only 49 in. from the dish shown, which is of very poor quality and technology, how was Archimedes able to project the sun's heat 150 feet. Ancient Greeks were far more techy than your teachers/professors will admit. My postulate/hypothesis is that Archimedes death ray might have been magnifying glass w. smaller mag. glasses and/or mirrors???

[jpmorgan187]

ditch the semi before going on camera..jeez

[321ozzy]

I enjoy your videos.

I calculated the focal point the following way:

F = Dsq /16d in which D = diametre and d = depth.

122sq/16*19= 48.96 inches, the focal point.

Honestly I could not solve your formula, could you add some numbers to it?

Thank you for your time and regards from Mexico

great video....let's do it at the Bustan in Kibbutz Lotan in Israel....Green Apprenticeship - Eco-Freako

[DisfiguredCowboy]

Great description..."afterwards, they will cook hot dogs on the dish."

[y117y]

It is an explanation that understands easily and Ne is the ..becoming

empty.. highest theoretically.

[pingpong1525]

nothing could stop it....except clouds :)

[wwwtotalitaerde]

@pingpong1525 Not to worry. Just use an electric, gas, wood or coal oven as a source of heat radiation.

[LordShiding]

@pingpong1525 an ever bigger one could stop this one

[JusticeLeague9]

Yeah, calculations are nice, but I'm hungry NOW! So, I'll take a spray bottle and mist the area around where the focul point should be. The brighterst spot in the mist is my focal point. As for the Archimedes death ray, if every person holding a mirror knew how to spot their reflection and were organized as the EXECT point to aim it, nothing could stop this weapon.
