Yes, renewable energy technologies exist. But solar power, the one with arguably the most promise for significant, scalable deployment, is intermittent. Although the sun provides more energy in one hour than humans consume in a year, we can only tap into this power when the sun is shining. At least, thatβs been the predominant school of thought.

But since the 1960s, a group of researchers from NASA and the Pentagon have been thinking outside the box β or in this case, outside the atmosphere. *Solar power captured in outer space would not be limited by nighttime hours or cloud cover.* _And β unlike 23 percent of current incoming solar energy β it wouldnβt be absorbed by water v***r, dust and ozone before reaching us. Finally, because space solar is constant, it wouldnβt need to be stored, which can lead to energy losses of up to 50 percent._

*We already know how to make this work.* With most proposals, *large mirrors on a satellite will reflect sunlight into the center of the spacecraft where it can be converted to either laser or microwave energy before being beamed to earth*. This beaming can happen uninterrupted, rain or shine, and at an intensity level no stronger than the midday sun, meaning birds and planes that get in the way arenβt in danger of frying. *On the ground, power-receiving stations will collect this energy and feed it into the grid.*

_One of the major draws is that this space-based solar power can quickly and easily be transported in shipping containers to a specific site in need, like a new military base or disaster area. And we already have all the functional pieces necessary to get started β no new physics need to be discovered. Itβs simply a matter of integrating them._
