As known, the Earth receives that solar radiation and its value approximately is equal to 1.4 W/m² (data taken from here: http://en.wikipedia.org/wiki/Solar_radiation ). Now imagine that there is some electric motor placed in the Earth’s orbit and it rotates the rod with some certain mass (let’s say 100 000 kg) and at some constant velocity (for example 2 revolutions/sec)
Can we calculate what amount of solar panels (I mean their total area in square meters) will be needed for rotating this rod by means of this electro motor?
