Centrifugal Impulse Drive (CID™)

 

Revolutionary Propellantless Propulsion

CID™ represents a breakthrough in satellite propulsion technology. Unlike traditional ion drives and Hall thrusters that must carry and expel propellant, CID™ generates thrust without ejecting any mass—a fundamental departure from conventional rocket principles.

How It Works
CID™ converts electrical power directly into propulsive force through a precisely engineered rotating magnetic field system. This eliminates the need for propellant storage, dramatically reducing satellite weight and complexity.

Key Advantages

  • No Propellant Required: Satellites can operate indefinitely without fuel limitations
  • Extended Mission Life: Potential for 3x longer operational lifespans
  • Reduced Launch Costs: Lighter satellites mean lower launch expenses
  • Sustainable Operations: Solar-powered thrust generation for continuous operation

Proven Technology
Independently validated at Georgia Institute of Technology and protected by pending U.S. patent (Application 18/252,296). 

 

CID™ Animation - How It Works
