About Us

More than 7% of the energy generated in the U.S. is lost during transmission and distribution. The U.S. Department of Energy estimates that half of this loss could be eliminated by the application of HTS. These savings could amount to $16 billion per year, reducing our use of fossil fuels, as well as the generation of greenhouse gases and pollutant emissions.
Our mission is ... to be the
leading commercial provider of
state-of-the-art superconducting
materials and related devices.

SuperPower Inc. uses core capabilities in materials, cryogenics and magnetics to enable the development of electric power components through its state-of-the-art second generation high temperature superconducting (2G HTS) technology.

These HTS devices will serve a variety of industries:


  • Low power loss, increased current carrying capacity transmission cables that provide utilities the ability to increase power in urban areas by using existing cable ducts, foregoing the requirement to dig up congested urban areas to lay new ducts.
  • Higher efficiency, lighter and more compact transformers with lower life cycle costs, containing no materials that threaten the environment or pose a fire hazard, and capable of operating above rated power without degrading life.

    Superconducting Fault Current Limiting (SFCL) Transformers add compatibility with Smart Grid Requirements by incorporating the FCL feature into the transformer device to rapidly detect and limit surges at high power levels that can be handled by downstream equipment.  
  • Superconducting Fault Current Limiters (SFCL) which provide the ability to limit damaging high-current transients (due to lightning strikes, downed tree limbs, etc.) resulting in increased operational flexibility for the electric utility grid and offer enhanced safety, reliability and power quality. There is no corresponding conventional device today.
  • Superconducting Magnetic Energy Storage Devices (SMES)
    High power and high energy storage in a compact device with modular units to address both long term (hours) and short term (seconds) storage requirements to help load leveling on the grid being led by variable renewable sources such as solar and wind.
  • Generators
    Generators with increased efficiency, reduced size and weight for windmill applications
Science, Research, Healthcare


  • Space Propulsion Plasma Rocket Engine

  • Motors and generators with increased efficiency, smaller footprint and lower weight when compared to conventional motors, produce energy savings, reduced pollution per unit of energy produced, and lower life-cycle costs
  • Magnetic Separation

  • Maglev Trains
    Maglev trains with the potential to be faster, quieter and smoother than conventional, wheeled trains
  • Ship Propulsion
  • Motors for Electric Vehicles

  • Electric Ship Propulsion
  • Directed-Energy Weapons
    More efficient and lower cost power for directed-energy weapons
  • Degaussing Cables
  • Pulsed Power Systems
