High Density Electric Energy Storage

Magtube proposes to develop a new class of inertial energy storage unit capable of very high energy capacity and power output in a far smaller package than is possible with any currently available technology. We have developed a novel concept thateliminates the primary failure modes of composite flywheels and allows nearly unlimited scalability. We will survey Navy operational requirements to develop target specifications for a prototype unit. We will then develop a design for the prototype,analyze critical components, build a test device to verify computed characteristics, estimate the size, weight, performance and cost of the prototype, and produce a solid model drawing with all components in place. Preliminary estimates suggest thepossibility of constructing a 1 GJ, 100 MW unit with a total volume of less than 4 cubic meters. Electrical energy storage has many applications in both military and civilian systems. For the Navy, our units will provide compact, light weight energy storage for aircraft catapults, pulsed power weapons and sensors, and general back-up power for
