Light Beam

A Gold output transformer outputs full daylight for 4 ebbs. Full daylight is quite energy intense.

With an appropriate system of mirrors (specifically a parabolic mirror), this can be turned into a beam of light. A pair of focusing lenses later, you have a tight beam of very bright light.


Why would you want such a thing? Well, for one thing, bubbles get obscenely expensive in terms of time as they get larger. And chaining wood transformers results in stupidly high losses.

You can use light beams to perform long range power transmission (10+ kilometers) at 75% maximum efficiency using a Gold input on the other end, with little required other than a set of focusing lenses if you need a waystation due to curvature and such.

Also, if you have enough UMD and ebbs, it's also somewhat like a laser cannon. No, that was definitely not an intentional result. =P
