Germany begins to develop its future energy by making the world’s largest artificial sun. The artificial sun is a German space-operated program, DLR.
The artificial sun is in a three-story building. At first glance it is like an ordinary office building. But the building holds something magical from science.
The sun made by German scientists is equal in intensity to 10,000 times the sun’s radiation on the Earth’s surface.
To make it happen, DLR scientists use technology that is often used by everyday people, namely a series of Xenon lights which number 149.
With this research they hope to be able to develop future fuels. Like fuel cells in electric cars, it’s just for airplanes or even cargo ships.
In principle, the artificial sun called Synlight functions like a solar garden. Its main task is to produce hydrogen as efficiently as possible.
Although abundant in the universe, Hydrogen on Earth is not usually a single element but is a compound with other elements. This one element is predicted to be the fuel of the future.
“Every year the sun sends 10,000 times the energy needs of humans to the surface of the Earth. So the amount of natural fuel is still very large, “said the project head, Kai Wieghardt.
Synlight’s working principle is quite simple. A total of 149 large Xenon lamps commonly used as solar simulations in filmmaking are focused on one point.
The lamp is used to heat the metal plate to a temperature of at least 800 degrees Celsius. After that the metal is covered with water vapor. The process binds to the oxygen atom on the metal surface, and frees the hydrogen atom.
Even so, artificial sun created by DLR scientists requires a large amount of energy supply. For four hours of operation, Synlight can absorb enough energy to supply electricity to a family home for a year.
But it must be admitted, the focus of the DLR experiment is to develop more efficient methods of energy production. Synlight is only a research installation to encourage Hydrogen production methods with solar cells.
In practice production does not have to use artificial lights. Morocco’s solar park in Ouarzazate for example has sufficient capacity to produce the same temperature as Synlight.
Later DLR will develop a method to produce hydrogen through a solar garden. According to DLR it still takes “years” to perfect the Hydrogen production method. Synlight is the latest technology tool.
