This required modeling and accounting for a number of factors, such as how gasses and particles in the atmosphere might absorb and scatter light, which would affect the amount of solar radiation at the planet’s surface. The winner: a photovoltaic array that uses compressed hydrogen for energy storage. tons versus about 9.5 Leaning on nature.
