Aetherflux Raises $50M Series A for Space Solar Power

Aetherflux Pursues Space-Based Solar Power

Space solar startup Aetherflux has raised $50 million in a Series A to launch its first orbital demonstration of space-based solar power transmission. The company aims to beam solar energy from orbit to ground-based receivers, a concept that has long been theorized but never demonstrated commercially at meaningful scale.

How Space Solar Power Works

The concept is straightforward: solar panels in orbit receive sunlight 24 hours a day without atmospheric interference, generating far more energy per unit area than terrestrial solar installations. Aetherflux's technology converts this orbital solar energy into directed energy beams that can be received by ground stations and converted back into usable electricity. If proven commercially viable, this approach could provide baseload renewable energy without the intermittency challenges that plague traditional solar and wind power.

Technical and Commercial Milestones Ahead

The $50M Series A funds the development and launch of an orbital demonstration mission. This is a critical milestone for proving both the physics and the economics of space-based solar power at scale. A successful demonstration would validate decades of theoretical work and position Aetherflux to raise the significantly larger capital required for full commercial deployment.
