We could soon be Getting Energy from Solar Power Harvested in Space

The idea of space-based solar power (SBSP)—using satellites to collect energy from the sun and “beam” it to collection points on Earth—has been around since at least the late 1960s. Despite its huge potential, the concept has not gained sufficient traction due to cost and technological hurdles.

Can some of these problems now be solved? If so, SBSP could become a vital part of the world’s transition away from fossil fuels to green energy.

We already harvest energy from the sun. It’s collected directly through what we generally call solar power. This comprises different technologies such as photovoltaics (PV) and solar-thermal energy...
