Solar powered oven Diy

Now it's hard to surprise anyone with how solar works on Earth. The sun powers us, heats our homes, gives life to our electronic devices. And the further it goes, the more solar energy enters everyday life, taking more and more new positions.

And now no one will be surprised with solar powered wristwatches, calculators, flashlights, receivers, cell phones. In hiking, on vacation, in the country, solar panels are irreplaceable. Today, cottages and cottages are being built, which rely entirely on "solar power supply" and do not depend on the common network of energy suppliers.

The sun provides these houses with electricity, the sun heats them, illuminates the garden near the house, the street. This amount of electricity is enough for all household appliances in the house to operate - refrigerators, TVs, vacuum cleaners, washing machines, electric ovens. But it's in the house. And what about outside the house, in the fresh air? In the summer it is much more pleasant to dine on the veranda, in the gazebo. Of course, you can cook your meals at home. And then bring it to the table. Or you can put a solar oven next to the patio, gazebo and cook everything on the spot. And, as they say, with enthusiasm, with heat - right on the table.

Solar oven at their summer house

The beauty of the solar oven is that it does not take up much space, and is easy to assemble and install. No fuel consumption, no pollution to the environment, easy to fold after use. This is the irreplaceable for a summer stay, for a picnic out of town, for a hike. These ovens can come in different sizes, different designs, folding and fixed, but they always have the same principle - capture the sun's rays in a beam and direct them to the location of the food container. prepare. And how this solar beam is used depends largely on the design of the furnace.

A parabolic mirror focuses the sun's rays on a special stand on which a water tank is mounted. After a short time, the water boils. Journalists photographed the marvel of this technology from all angles, some short notes appeared in the press, and that was the end of the matter. The industrial production of such devices was subsequently abandoned.

But craftsmen, unlike industry, accept the novelty with enthusiasm. They began to modernize it, new design solutions appeared, a lot of homemade equipment. These are proven parabolic mirrors, but with a rotating mechanism that allows the mirror to rotate with the sun without changing the position of the cooking vessel. These are also solar furnaces made from scrap materials - wood, cardboard, tin. There are also more elaborate designs that combine a traditional mirror concentrator and an oven.

All these devices are lightweight, compact, easy to assemble and disassemble. They take up very little space in a backpack and require no fuel. So they are more than willing to take them with them on long hikes, to various suburban picnics. After using them, no ash, no coal - nothing. And you can cook anything on these ovens. From simple boiling water to fish soup, grilled meat, grilled meat.

DIY solar oven

It is not difficult to make a solar oven yourself. Usually, at the beginning of production, they are only instructed on what, in fact, the structure is built for. And the question of how to make a solar oven is not worth it at all. If we are talking about the installation of such a stove in the country, in a cozy place near a country house, then here you can think of building a permanent, solid structure. For hiking, you can use the lightweight collapsible design. The installation is more complicated, but also collapsible, which can be done if you plan to drive out of town for a picnic.

For a more complex structure you will need a not too large cardboard box (up to about half a meter on each side), four wooden slats the same length as the height of the box, with a cross section of 25x25 mm, glass of the same size. measure the sides of the box.

You'll also need heat-resistant black paint (it's definitely non-toxic!), some bricks (how many bricks will fit in the bottom of the box), mirror film, or aluminum foil. Paint the inside of the box with black paint. Paint the bricks with the same paint. Can be painted in two layers.

Leave it for a while for the paint to dry and its smell to disappear from the box. Glue mirror film or foil to the top four wings of the box. Strengthen the wooden blocks in the corners of the box. The glass will hold them tight. Place the bricks on the bottom of the box. Now still have to put it in a place with maximum sun exposure. The oven is now ready for use.

Industrial Solar Furnace

As for the industry-made solar furnaces, their creators have given free rein to their imaginations, equipping them with all the conceivable and unthinkable. can imagine. Lightweight, collapsible like a suitcase, they're in place in minutes. These furnaces combine the advantages of a parabolic cylindrical concentrator and a solar vacuum tube.

Solar cooker oven

A long vacuum tube is placed at the focal point of a cylindrical mirror with a parabolic shape. But instead of containing a low-boiling liquid, there is a tray in the inner compartment, where the cooking products are stacked. The pallet is inserted into the tube and fixed. The vacuum around the inner cavity provides reliable insulation and high temperature inside it. The temperature in the internal cavity can exceed 300°C.

Vacuum tube with adjustable display

To control the temperature in the working chamber, a thermometer is fitted at the top of the vacuum tube. It is an integral part of the electronic control unit. This block has a thermostat with a preset operating temperature, a mirror rotation control system, a timer that closes the mirror after a specified time, and an audible signal. All electronics are powered by a solar panel built into the case.

When assembled, this oven looks like a suitcase about 75 cm long, about 40 cm high, 11 cm thick, a little heavier than 4 kg. And you can cook anything in it: meat, fish, vegetables. You can bake cupcakes. And of course, its most important advantage is that it is an absolutely environmentally friendly device that does not consume any other energy except the energy of the sun and does not pollute the environment.
