Found a way to produce energy during the lunar night
Modern science can not only explore the moon with telescopes on Earth, but also directly by sending a variety of devices on the moon’s surface. But on the moon for 14 Earth days continues moonlit night, during which the temperature falls to a temperature of -150 degrees Celsius, which adversely affects the space equipment.
For the operation of all systems need electricity and heat, which is often produced by solar energy, which is absent in the dark. To complete the work necessary to carry large batteries or use nuclear fuel. But scientists have come up with two ways to use solar energy in the dark.
The first method is to change a piece of regolith, or moonstone, by combining it with elements like aluminum, to form a thermal mass. During the lunar day, the sun heats this mass, which subsequently gives off heat Lunokhod and other devices during cold weather.
The second system is similar to the first, but it uses a complex system of mirrors in conjunction with the heat engine. Mirrors work as Fresnel reflectors directing the sun’s rays on a liquid-filled tube. The heat transforms the liquid into a gas, which heats the thermal mass. During the lunar night heat is supplied to the heat engine that generates electricity.
“This system is more suitable for lunar projects , which requires more energy, for example, such missions, which assume the presence of man on the moon during the lunar night, “- says research physicist Gonzalez-Chink.
These inventions are already interested space agencies – NASA, ESA, China National Space Administration, Agency of Japan and India.
