Would that not be impossible because of the lack of effective cooling in space? The only way to get rid of heat in space is by radiation, which is a very inefficient process. Assuming temperatures cannot rise above 100°C, every square meter of radiator fin emits at most a kilowatt. And because half the orbit is spent in direct sunlight, a significant part of the surface area will have to be reflective, making it useless for radiating heat.

Also, where'd you get the power? Solar panels will only yield a kilowatt per square meter at most, for half of the orbit. Beam it up from Earth?
