NASA lays out the path to space-based solar power

Instead of collecting the sun’s energy on the ground, it may be possible to harvest it in space using satellites.

A new NASA report found that space-based solar power — a futuristic concept pulled from the pages of science fiction — is likely too expensive to work, but it also lays out exactly what would need to change to make it a viable source of clean energy in the future.

The challenge: Solar power is a revolutionary weapon in the battle against climate change. Every hour, enough solar energy hits Earth to power the entire world for a year, and the cost of harnessing this energy with solar panels has fallen exponentially in recent years.
