What is BOHR?
- BOHR (Betavoltaic Orbital High-Reliability) is an experimental commercial satellite developed to demonstrate betavoltaic energy technology in space.
- Unlike conventional satellites that depend primarily on solar panels, BOHR carries a NanoTritium battery, which converts energy released from the natural decay of tritium into electricity.
- The mission is intended to validate whether this technology can provide a reliable, maintenance-free power source for future commercial spacecraft.
What is Betavoltaic Technology?
Betavoltaic technology is a type of nuclear battery that converts the energy released during the radioactive decay of tritium into electrical power.
Working Principle
- Tritium undergoes radioactive decay.
- Beta particles are released.
- Semiconductor material captures these particles.
- Electrical current is generated.
- The battery continuously supplies low-power electricity for years.
Unlike a nuclear reactor, no chain reaction takes place.
NanoTritium Battery
The BOHR satellite uses Nano Tritium battery technology, developed by City Labs.
Features
- Extremely long operational life.
- Maintenance-free.
- Compact and lightweight.
- Resistant to harsh space environments.
- Reliable continuous low-power output.
