Matteries

Could you make a battery whose stored energy is 100% of its mass?  Call it a matter battery, or mattery.

We'd be golden if we could totally convert natural matter into energy.  But natural matter is very complex and very stable (of course; it has been around forever), and it seems that every time you extract energy from one level of structure (e.g. fission), there's more mass left (e.g. protons) and yet another level of structure to be broken down.

What if we created our own synthetic matter straight from energy, in a form which would be simpler and easier to break down on demand?  

For example, if the Large Hadron Collider discovers this new, skinny little dimension they're looking for, then maybe we have a nice storage space cut out for us already...

Imagine we send a light wave into the direction of this tiny dimension, so that it loops around forever.  Would that trap it?  No; over time a ray of light eventually spreads out and disperses.  So how do we hold it together?  Emit a second light wave into this dimension, parallel and superposed upon the first, but headed the opposite direction.  Each light wave should be of such high energy density as to have a gravitational field that acts as a lens upon the other wave.  Each light wave's gravitational lens prevents the other wave from spreading out, so they are mutually trapped.

If the wavelengths of the light are the same, and an even ratio of the tiny dimension they travel, then they will be a standing wave, and look like a pulsing stationary particle.

To release the energy, we would inject a third light wave at an angle through the loop.  The third wave's gravitational lens would deflect one of the trapped waves just a little bit out of parallel to its partner, breaking the trap open, and releasing energy to the outside world.
