🛠️ Technical Deep Dive
- •Space-based solar array utilizes thin-film photovoltaic (PV) cells with a thickness of less than 50 micrometers to minimize launch mass.
- •Energy transmission from orbit to ground stations is achieved via high-frequency microwave beamforming, targeting rectifying antennas (rectennas) located near datacenter sites.
- •Iron-air battery chemistry relies on the reversible oxidation of iron (rusting) and reduction (de-rusting) to store and release energy, providing a discharge duration of up to 100 hours.
- •Integration layer uses AI-driven predictive load balancing to switch between grid, orbital solar, and iron-air storage based on real-time energy pricing and grid stability metrics.
