Elon Musk wants humanity to harness the Sun’s entire energy through a concept called a Dyson Sphere, a massive megastructure first proposed by physicist Freeman Dyson in 1960. Musk believes advanced AI, Mars colonization, and human survival all require far more power than Earth’s current energy sources can provide.
He publicly stated his goal of reaching “Type II” on the Kardashev Scale, a civilization that fully controls its star’s energy. SpaceX has already filed with the FCC mentioning a “Kardashev level-II civilization,” planning AI-powered solar satellites generating up to 100 gigawatts yearly within five years.
However, critics warn this dangerous geoengineering could alter rainfall, devastate food production, and raise serious questions about who ultimately controls Earth’s sunlight.
