#1 Starcloud (formerly Lumen Orbit), white paper v1.03 said on 2024-09-01 · source
Energy costs in orbit can be around $0.002/kWh, about 10x cheaper than terrestrial data centers.

The core of Starcloud's claim relies on an exceptionally low launch cost of $30/kg, which is contradicted by multiple independent sources. While the solar power generation cost and the TCO premium are supported, the overall claim of energy being 10x cheaper is not. The claim is partially contradicted due to the unrealistic launch cost assumption.
