Photon loop capacitor

A Photon loop capacitor is a power storage system which converts electrical power into specific wavelength photons and stores them in a coiled fiber optic cable. Upon discharge the photons are re-absorbed and converted back to electrical power.

The advantages of a photon loop capacitor is, because photons have negligible momentum and don't interfere with each other, it offers a theoretically unlimited power storage capacity. And, as the power is stored as simple light, if the capacitor fails, there is far less damage to the surrounding environment than with other power storage system.

In practice, neither is quite true. Photons do have a tiny momentum which will overcome the even the strongest material if there are enough photons. Even so, the photon loop capacitor has a power storage capacity that can easily match theoretical limits.

One limitation of the device is the rate of conversion for both the photon emitter and absorber. Usually these are precisely matched as to wavelength and can achieve a restoration rate of 99% or better.
