Alex Freundlich (Alex Freundlich) and his colleagues at the University of Houston (University of Houston) demonstrated the feasibility of building robots solar cells from lunar dust.
The very idea of a lunar power completely from the lunar dust was nominated Alex and his team four years ago.
In their eyes, wheeled robots could move on the lunar soil — regolith, taking it on board, cleaning, melting and putting back on the moon in the form of traces of feeds to which could only implant the wires to remove the "sunshine" electricity.
A set of robots, having a considerable distance, gradually built up a large solar panels needed to power the lunar colony.
The main highlight of ideas — all of the components needed to create solar panels, there is in the regolith, which is half of the silica and half — of a mixture of oxides of 12 metals, including aluminum, magnesium and iron.
Now Freundlich shown by experience that a key part of this plan should work. He modeled the fact that the rovers will have to do in a perfect vacuum chamber that simulates the conditions of the moon.
Researchers fused powder JSC-1, which has a composition identical to samples of regolith brought by astronauts on the moon, and then let it harden into a very smooth sheet.
The authors further experiment showed that the basis of this material to create a solar cell capable of producing a current.
However, the efficiency does not exceed one percent, but on the moon it may not matter, since the amount of raw materials for the production of panels — practically inexhaustible.
