How To Make That Old Satellite Dish Cook All Your Meals

Grab that old satellite dish out of the dark corner of you garage and get those hot dogs ready. [Share alike license] is going to show us how to turn the dish into a solar cooker.

Harnessing the sun’s power requires a reflective surface. Although the image above makes it look like a mirror finish, this is really just covered in foil tape. This is what’s used to seal duct work and can be had for a few bucks at any home store. You’ll notice the dish is pointed up quite a bit more than it would have been when receiving satellite television. The mount on the back of the dish has been turned 180 degrees to allow for this. You want the rays to be focused on the bottom of the cooking area instead of the side and this will do the trick. A small grate was added just below the pinnacle of the receiver tripod. For now it has only been used to boil a pot of water. We’d like to see it grilling up some dogs but you’ll have to figure out a way to catch the drippings. We wonder if a transparent baking pan would block too much of the heat energy?

This is a great way to add purpose to neglected equipment. But if you’re serious about solar cooking you need something more along these lines.

Various Cantenna Builds

Here is a classic project used to increase wireless signal strength. Cantennas focus using a waveguide very much like a magnifying glass focuses light. [Robert] made a Natural Light beer cantenna, pictured in the upper left. His approach used three beer cans, a paper towel holder, and a shower curtain rod. On the tipline, he noted a signal boost from 11Mbps to 54Mbps. This is certainly something we can hack together if our room lacks adequate signal. Read about parabolic and seeking versions after the break.
