>if you set up a solar panel that directly feeds a resistor, you have a dissipative system that's unlikely to get hotter than the sun. I guarantee you this can be done. Arc welding [1] goes to many thousands of degrees, up to 20,000C. A square mile of solar panels will most certainly give me enough energy to power an arc welder. In fact I will probably will get away with just 100kw of pwoer, so 500 panels give or take.
