One of the biggest problems facing solar power is its intermittent nature. As our planet spins the sun rises and sets, as does the power generating nature of our solar arrays. While that axiom is true on Earth, however, once you leave the planet the Sun’s radiation is constant, undimmed by a rotating globe. With an eye towards that advantage, NRL researcher Paul Jaffe is designing a series of solar modules that could be assembled into a large, space-based satellite and used to collect solar energy without interruption.
Working with two prototype models that contain solar panels, an electrical system and an antenna, Jaffe and his team are attempting to develop a self-contained system that can absorb solar energy, covert that energy to radio waves and beam it back to ground stations here on Earth. In its full blown vision the NRL’s solar array would be a kilometer wide assembly of Jaffe’s self-contained solar panels interlinked into a massive energy net.
Given that fact, the NRL doesn’t plan to create a large, space-based solar array anytime in the near future; though that isn’t stopping pioneering scientists like Jaffe. While similar plans from a Japanese corporation and California’s Solaren are equally as ambitious as the NRL’s attempt to create a space-based solar power plant, Jaffe’s response to criticism is definitely the best: “Hard to tell if it’s nuts until you’ve actually tried.”
