Space-based, solar-powered data center constellations are being proposed as a radical solution to the sustainability crisis facing terrestrial data centers, which consume vast amounts of land, water, and power. By moving computing infrastructure to orbit, these systems aim to harness 24/7 solar energy and natural cooling, potentially offering up to 10 times lower carbon emissions over their lifespan compared to fossil-fuel-powered terrestrial data centers. However, this vision faces severe sustainability and technical hurdles, including high-impact rocket launches, space debris risks, and the difficulty of repairing hardware in orbit.
The existing body of international law is not well-suited to the concept of a nation "owning" the energy of the sun.In the Outer Space Treaty of 1967, it was stated that space is the "province of all mankind" and that it is forbidden for any government to appropriate space for its own use. On the other hand, it does not expressly prohibit the acquisition of solar energy for commercial purposes.When it comes to radio frequencies, the International Telecommunication Union (ITU) is in charge of managing spectrum contention. It is necessary for SBSP to have enormous "chunks" of the microwave spectrum. In the event that a solar constellation "pollutes" the frequencies that are utilised for global positioning system (GPS) communications, weather satellites, or research in deep space, it may result in severe diplomatic sanctions or electronic warfare.
Space-based Solar Power (SBSP) has the potential to significantly alter the wealth of nations:
Countries with strong launch capability but low natural resources, like as Japan or portions of Europe, have the potential to suddenly become energy exporters. This is accomplished through the concept of resource-poor, orbit-rich.The decline of petro-states: If SBSP were to become more affordable than oil and gas, the conventional geopolitical influence that oil-producing countries have would be lost. This may potentially lead to instability in those regions as their principal source of revenue would be eliminated.
