Although a concept, utilizing the moon's surface to collect solar energy is not only crazy, but also ingenious and plausible.
Japanese firm Shimizu is calling their lunar solar power generation concept the Luna Ring and it's brilliantly ambitious. The way the Luna Ring works is by gathering solar energy with a 6,800 mile long solar belt across the Moon's equator that'll be transmitted to Moon-based energy conversion facilities. The converted power will then be beamed to Earth-based facilities with laser power and microwave power. Once on Earth, we'll be able turn all that power into electric power for our power grids or hydrogen fuel.
