Off-The-Grid COMET models

I've been working up some 3D models (using SketchUp) of the COMET as she may end up, or the "end result" models.

These are likely to change as the design process continues and ideas solidify, but here was what I first envisioned The COMET to look like.

Perhaps the rainwater harvesting system will change, and the solar modules might be in different places or as a separate array that pops up and can move around in order to collect optimum sun, but here's my totally self-contained version of The COMET of the future.
