Solar Powered Stove

Nowadays, the satellite TV antenna often becomes trash because of Internet video broadcasting. At the same time, reducing the environmental footprint and recycling materials and tools are becoming increasingly important. This is where the idea came from to make a solar-powered device out of unnecessary things and a few pennies worth of materials.

Supplies

old satellite dish, plain square tube, survival blanket, 2x corner brace, drill,

twist drill for metal, nuts, bolts, washers, paint, double-sided adhesive tape,

Creating the Model

Based on the imagined idea, the 3D model was created with Fusion.

Preparation of the Dish

Take the antenna, wipe its surface, and stick the pieces of double-sided adhesive tape. Use at least 5 pieces per quarter, as shown in the picture.

Fixing the Reflective Film

Proper fixing of the foil is very important for the right result. First, peel off the protective paper from the adhesive tape on the center line. Stick the foil with the silver side visible.

Then, in one semicircle, peel off the protective paper from each adhesive tape. Make sure that the foil does not stick to the satellite dish. Hold the foil taut with one hand and press each strip to the glue with the other hand.

When you're done, repeat on the other half circle.

Finally, cut off the excess part of the foil with scissors.

Making the Pot Holder

The square tube must be at least 60 cm (24 inches) long. The square tube must be drilled in two places with a 6 mm (1/4 inch) drill bit. The recommended distance for holes is shown in the picture.

Then both corner braces must be fixed with screws to the holes next to the end of the tube. See the next picture.

Optionally, you can paint the finished holder.

Assembling

First, the holder of the LNB must be removed from the satellite dish.

Then drill a 6 mm (1/4 inch) horizontal hole at the end of the console.

Finally, attach the pot holder to the LNB holder with a long screw. See the picture.

Important: The screw must be fixed in such a way that the pot holder can rotate. Since almost the entire length of the pot holder is below the rotation point, the support rod is always vertical, and the pot is horizontally on top.

Stand Up

The satellite dish must be fixed in the same way as when it is installed for TV reception. The support bar can be free-standing or fixed to the wall.

Things to pay attention to when placing:

Do not put it in a shady place.

Place it so high that the pot holder rod does not touch the ground when the satellite dish stands vertical.

The antenna should be able to turn horizontally.


Use It!

The device produces the most heat when you point it exactly toward the sun.

To do this, first set it horizontally. It helps if you put a quick tie on the LNB holding rod in a vertical position. Look at the picture. Next, turn the dish until the shadow of the quick-tie is exactly aligned with the edge of the support bar.

After that, tilt the antenna in a vertical direction until the reflected light of the sun is visible at a point on the side of the dish. Do not forget fix the screws.

Review and Comments

The highest temperature recorded in May was 449 Fahrenheit at the time of the test. The highest documented temperature during the test was 362 Fahrenheit; you can see a video about it.

The location of the test is in Hungary at 47.7 latitude, which is the same as Seattle's latitude. The further south the location is, the stronger the sun's radiation.

If the heating lasts longer, it is necessary to rotate the antenna according to the movement of the sun.

You can achieve the highest temperature with a dark metal pan. Shiny steel cookware is not suitable because it reflects light and heat.


Good luck!
