oh yes, this stuff of PV panels in space is an old fad.
The article is funny by the way...
In doing so, the small machine's solar panel is capable of storing phenomenal energy to then redirect it in the form of a “ray in the form of microwaves converted into clean energy” towards a given location.
Oh yes ? Further on we read...
“The latest experiments show that the 30,5 x 30,5 centimeter panel is capable of producing approximately 10 watts energy to transmit. That's about enough to power a tablet."
ah the idiots... already it's a POWER, not an energy, and moreover it's almost nothing and not terrible.
On Earth, the same PV surface illuminated by 1000 W at 20% efficiency would have produced 18 W, do the math...
But what a bunch of tench... The losses in efficiency are enormous in converting energy into radio waves, transmitting them to earth and converting them back into electricity. And above all, there must be no clouds or water vapor on the path of the beam...
On the other hand, it will really pollute space, all these satellites will fall into disuse and produce extremely dangerous debris.
