| An energy storage device is proposed that utilizes acceleration of particles to near relativistic velocities to store energy in the kinetic energy of accelerated particles. Designs and models are provided for a commercially feasible device that implements the concept. The device allows tremendous performance capabilities across many parameters including energy density. Multiple innovations are also proposed for methods to reconvert the kinetic energy of accelerated particles back to electricity. In addition, certain innovations are proposed for accelerated particle beam control, beam particle designs and beam confinement rings. The device is different from existing particle collider storage rings in that it maximizes total beam energy, not energy per particle by accelerating particles to velocities substantially less than the speed of light. In addition, it includes innovations to meet the requirements of the commercial market with specific applications in markets such as grid level storage and energy storage for vehicles. | ||||||

| 176 | Micro free electron laser (FEL) | US11411129 | 2006-04-26 | US07876793B2 | 2011-01-25 | Jonathan Gorrell; Mark Davidson; Michael E. Maines |
| A charged particle beam including charged particles (e.g., electrons) is generated from a charged particle source (e.g., a cathode or scanning electron beam). As the beam is projected, it passes between plural alternating electric fields. The attraction of the charged particles to their oppositely charged fields accelerates the charged particles, thereby increasing their velocities in the corresponding (positive or negative) direction. The charged particles therefore follow an oscillating trajectory. When the electric fields are selected to produce oscillating trajectories having the same (or nearly the same) frequency as the emitted radiation, the resulting photons can be made to constructively interfere with each other to produce a coherent radiation source. | ||||||
