Superconductors. Average temperature in space is around 4 K.
Even assuming that this la-la-land idea has merit, the equilibrium temperature at the Earth's orbit is 250 Kelvin (around -20C). The space around the Earth is _hot_.
you do know about the Sun? Earth? and the Moon? where would you get this 4 kelvin?
