MIT and NASA’s 2024 betavoltaic batteries harness radioactive isotopes:

• 90-year lifespan: Ni-63 isotopes decay in diamond semiconductor layers

• Zero charging: Continuous 24/7 power from nuclear decay

• Space-grade reliability: Survives extreme temperatures (-200°C to +150°C)

Game-changing applications:
▶️ Off-grid sensors: Powers Antarctic climate monitors indefinitely
▶️ Medical implants: 50+ years operation (human trial starts 2025)
▶️ Lunar outposts: Selected for Artemis Base Camp power

Metrics:

• Energy density: 3,300 Wh/kg (10× lithium-ion)

• Safety: UL-certified radiation containment

• Cost: Projected $2,000/kW for permanent installations
