  2. I have been having trouble obtaining a satellite dish. Does anyone have any clues on where to look for one in Las Vegas Nevada?

  3. I was concerned that the tape would not stick to the coating on the dish. Somewhere I read (not sure where) that tape doesn’t stick well to it. I don’t know this from experience, though. I found the tape on eBay. It was entitled “Silver Chrome Mirror Vinyl Tape 2″ wide” I made sure the image showed tape that was very shiny and mirror-like. I think some automotive or hardware stores sell it as well. I don’t have a brand or item number – hopefully this helps.

  4. I’m not clear on the chrome vinyl tape. Please tell us EXACTLY what to buy. I don’t want to screw this up. Also, why did you paint this after sanding? I will appreciate hearing from you so I can complete my cooker. Your video is great.

  6. On the German Ebay there are 120cm dishes for 79,- (new). But believe in me: size does matter! (surface = pi * r²) or (surface = pi * d²/4)
    1,2m diameter equals 1,13m²
    1,0m diameter equals 0,78m²
    0,8m diameter equals 0,50m²
    You see, a 80cm dish gets you only half of the energy of my 120cm dish. I wouldn’t recommend that if you really intend to cook. Of course it’d work, but you would be happy with it.

  7. Thanks for the info, good vid! I just made a solar cooker with a 80cm dish. I bought it for 29 euros. The pricing for another brand which delivers dishes of bigger sizes it is the following: 45euros for a 80cm dish and 120euros for a 100cm dish. So prices almost triple to buy a dish only 20cm bigger. So when you can’t find an old dish, buying a 120cm dish doesn’t seem a cheap option to make a dyi-solar cooker. Unless somebody knows a website where to buy cheap dishes?

  9. : My self-made solarcooker has a Diameter of 120cm. If you really want to cook with it, it shouldn’t be less than 120cm. The sun provides about 1000W/m² of energy at 12:00 o clock. With a diameter of 120cm you have a surface of 1,13m². I have made a video that explains more

  10. My dish is only 22 inches in diameter. I suspect it will be limited to small cooking containers and small quantities of food. I have not yet had an opportunity to try it. I did light a few things on fire with it to see where the focal point is (see my other video on that), but time will tell if it does well cooking food. I will definitely post a video showing its capabilities (or lack thereof) when I use it.

  11. What diameter does your dish have? 33inch? Commercial solar cookers mostly have 50inch (120cm) diameter. So I wonder if you can still easily cook 2 liters of water with a 33 inch. 50inch dishes are more difficult to find or expensive.
