At the centre of our solar system lies great power. The Sun bathes our tiny blue world with an immense amount of solar energy... many thousands of times the world's current energy usage. Exploiting solar makes so much sense. In space, solar power has been used for a long time. Satellites have advanced photovoltaic cells based not on silicon, like our rooftop cells, but on gallium arsenide. These are more efficient but generally too expensive for use on Earth.

But that may be changing.
