Clean Power solar death ray

Solar “Death Ray” (VIDEO)



 

I’m not sure if this is cleantech —  it could certainly be used for good if wished (if it weren’t destroyed in a shed fire… that it probably created), but the idea is a big part of what’s behind concentrated solar power. A Facebook friend actually shared the video with me this week in response to my home heliostats post — thought it made for a fun weekend share. :D

Needless to say, the preface to the video should be “don’t try this at home.” (Otherwise, you might burn down your shed.)

Here’s more info on the solar death ray and future plans from the YouTube page:

The R5800 is my latest and greatest solar creation. Made from an ordinary fiberglass satellite dish, it is covered in about 5800 3/8″ (~1cm) mirror tiles. When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 times normal daylight. This intensity of light is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant. It stands at 5’9″ and is 42″ across.
Unfortunately, the R5800 was completely destroyed in a storage shed fire on December 14, 2010.

Coming spring of 2011:
Sun Runner 3
R23000 (R23K)

Area of dish aperture (elliptical)= (pi x 102cm x 73cm)/4 = 5848 sq cm
Area of focal point (circular)= pi(0.6cm)^2 = 1.14 sq cm
Concentration Power= 5848/1.14 = 5129 then rounded down
Output Power Estimate = 560 watts

    Isn’t this how they took out the Lost Continent of Atlantis?

    It could heat, roast, burn, weld, disinfect, power, and look nice… The 75% efficient ones by ZenithSolar could power 10% of Israel (1 GW) using 12 square km.

    Cool, but a little disconcerting.

    Never thought of using a sat dish for something like that,

    Oh, and hey, CleanTechnica editors – don’t forget you are able to alter the size of the video embeds! Often times your videos are misaligned, and are cut off by your sidebar content. Don’t forget to change the width of the embeds.

      hey, thanks. WordPress used to auto-fit them when using the share link. Will have to keep an eye on that and perhaps use the embed code again. Thanks.

        No problem. Like your site(s) Good material, enjoyable reads.

    Lets hit rewind for about 2228 years to the time of Archimedes. He was the first to use polished Greek shields to set the Roman ships on fire.

      Indeed.

    Looks like fun!
