  1. How to make a Solar Tyre Oven With Moses from Uganda

  2. What you need… An old tyre, a glass square big enough to cover it, a black pot, silver foil, newspaper, tape, cardboard, something to weigh the glass down… and some sun!

  3. Cardboard Place the cardboard on the ground, making sure that it is flat. This acts as extra insulation for the oven.

  4. Tyre Put the tyre onto the cardboard. Check that there are no gaps between them. The tyre absorbs heat from the sun.

  5. Newspaper Add newspaper all around the inside and the base of the tyre. The newspaper traps air and adds more insulation.

  6. Silver foil base Put a base of silver foil inside the tyre to reflect the heat.

  7. Silver foil lining Add a long length of silver foil all around the sides and inside of the tyre. This acts as your main solar reflector (like a mirror).

  8. Silver foil lining Try to make sure that there are no gaps. Then tape the ends together.

  9. Glass square Tape the edges of the square of glass* to avoid accidents. A circular piece of glass will be even safer. * the glass we used was 64 x 64 cm

  10. Black pot Place a black pot into the middle of the tyre; using a black lid is even better. Try a stew* without much water content at first. * we cooked a pumpkin and rice stew

  11. Add the glass Put the glass on top of the tyre, ensuring there are no gaps. Add some weights to avoid heat leaking out of the oven.

  12. Leave in the sun Make sure that your oven is in full sun with no shadows. Leave it for about 4-5 hours, depending on the strength of the sun and what you are cooking.

  13. How it works Solar radiation enters through the glass and UV light is trapped inside the oven. Light reflects off the silver foil and warms the heat absorbent black pot. Heat is kept in the oven by the newspaper and cardboard insulation. The black tyre absorbs heat, helping to heat the whole oven, and it adds extra insulation.

  14. Taste! Check your food to see if it is cooked. Try not to let too much heat escape – be careful, it may be very hot. Then taste it!
