Photovoltaic/Storage Cell

Photovoltaic cell, it generates electricity responsive to sunlight, … in clean manner. The most serious drawback of the solar cell is that it can produce zero output power when light to the cell is zero or weak, … well, for example, at night, in rainy and cloudy days.

The output power drops to zero.
And the zero output power state continues for a long time.
I don’t want to use the word “variation” to express the power level changes.
I have felt for a long time that the solar cell device has been used quite luxuriously.

There are many ways to level the output power of the solar cell.
Its examples are combinations with secondary battery, fuel cell or the like.

A bold scheme is present to make full use of the solar cell.
A solar power generation station is located at such a place in the universe as to allow the station to constantly receive sunlight. Electric power from the station is transmitted to the earth by space propagation medium, e.g., microwave.
This is really an ideal power leveling approach.
I know that the United States has a plan to demonstration test the scheme in around 2015. This is a grand experiment.
