This article describes the scientific motivation and high-level concept for a warning system for advanced space weather prediction with increasing accuracy. As humanity’s reliance on microelectronics and orbital infrastructure reaches critical levels, our civilisation faces an unprecedented vulnerability to solar volatility. While the original Dyson sphere was a thought experiment in energy harvesting, the “new Dyson sphere” is a pragmatic necessity for planetary defence: a distributed, interplanetary framework of information-capture constellations. By integrating multipoint spacecraft clusters, standardised mass-produced units, and real-time AI forecasting, this proposed system moves beyond the 30-minute warning window of current Lagrange-1 point monitors. It offers a paradigm shift in heliophysics – providing the 12-hour lead times essential for stabilising global power grids, protecting satellite networks, and ensuring the safety of Artemis and Mars explorers. This article outlines the scientific breakthroughs in Kelvin-Helmholtz wave detection and the industrial standardisation required to turn space weather from a trillion-dollar threat into a manageable operational event. Introduction Sixty-four years ago, physicist Freeman Dyson proposed a thought experiment that became a staple of science fiction: an …
