Server Sky - internet and computation in orbit
Server-sats are ultralight disks of silicon that convert sunlight into computation and radio energy. Powered by a large solar cell, propelled and steered by light pressure, networked and positioned by microwaves, cooled by radiation into deep space. Arrays of thousands of server-sats act as highly ation isolated inside a traditional satellite bus.
Traditional data centers consume more than 2% of US electrical power, and this fraction is growing rapidly. Server arrays in orbit can grow to virtually unlimited computation power, communicate with the whole world, pay for themselves in electricity savings, and greatly reduce pollution and resource usage in the biosphere.
