Space-based solar power was named one of five technologies "that could change everything," by The Wall Street Journal.
The ability to tap power from space, for instance, could jump-start whole new industries, the newspaper says.
If we could place giant solar panels in orbit around the Earth, and beam even a fraction of the available energy back to Earth, they could deliver nonstop electricity to any place on the planet.
The cost of sending solar collectors into space is the biggest obstacle, so it's necessary to design a system lightweight enough to require only a few launches.
Several countries and companies aim to deliver space-based power as early as a decade from now.
