About Ethos Space Resources
Ethos makes silicon on the Moon to power terawatt scale data centers. The Moon's surface is 21% silicon. We melt and electrolyze the lunar surface to make raw materials for solar panels. With solar panels made from the Moon, the constraint that limits data center scaling and everything else in space is gone.
