Solar Power From Space

Data centers need power. A lot of power. People don't want data centers in their neighborhoods. Where will it come from? From space?
Meta announced a deal with startup Overview Energy to purchase solar power collected by satellite and beamed back to Earth.
It is an experimental approach that could power data centers at night. Unlike traditional solar power, which relies on storing daylight, space-based solar power aims to deliver continuous energy.
Overview Energy plans to deploy satellites over 22,000 miles from Earth's equator, where they would collect and transmit infrared energy to solar panels. A test is scheduled for 2028, with a commercial rollout in 2030. Meta is seeking up to 1 gigawatt of power from the project, underscoring its energy needs for AI.
It sounds a bit wishful thinking if you look at the numbers. In 2024, Meta's data centers consumed 18,000 times the electricity that this deal would deliver in a single hour.
Space-based solar power (SBSP) involves harvesting solar energy in orbit and beaming it to Earth, providing 24/7 clean energy unaffected by weather, nighttime, or atmospheric filtering. There are challanges: high launch costs, complex orbital assembly of massive structures, and wireless energy transfer.
