The invention of the ancient Egyptians will help to do without air conditioning

Technology of ancient Egypt is shrouded in mystery and studied so far. For example, in August of 2018, scientists have discovered that the Great pyramid of Giza is able to produce electromagnetic energy. It is also known that the Egyptians were the first who began to resort to plastic surgery. As the study of ancient technology researchers find new applications. So, scientists from the National laboratory Lawrence Berkeley believe that the Egyptians invented ink can be used to cool buildings and generate electricity.

This paint has a blue tint — the Egyptians used it for the image of the gods and the Royal family. It is obtained from a silicate of copper and calcium, and in modern times is known as “Egyptian blue” or Alexandria Lazur.

Previous studies have shown that the surface painted with a paint that absorb sunlight and emit it as light of the near-infrared range. New work by scientists from the National laboratory Lawrence Berkeley proved that the power of radiation 10 times more than previously thought. In particular, it States that the surface emits nearly the same amount of photons, and how much absorbs.

The research team, led by Professor Paul Bardales, believes that this paint can be used to cool roofs. To do this, at the moment used white paint, but for aesthetic reasons it paint only horizontal roof, not visible from below. Blue color can be used in roofs sloping shape.

Also the “Egyptian” blue, you can paint the window. It is believed that the emitted photons can be absorbed by solar panels that produce electricity. This may allow not only cool the building but also save energy.

The “Egyptian” blue, there are more large-scale use. Reflecting solar rays back into space, paint cools and the planet as a whole, reducing the risk of global warming.
