Bernal suggested that if humans hollowed out small asteroids, they could outfit them as solar collectors, thus capturing far more solar energy.

Theoretical physicist Freeman Dyson, a professor at Cornell University and then at the Institute for Advanced Study in Princeton, took Bernal’s ideas and expanded on them.
