Cloudburst 1 starts off with plans for a 16' dome. If you are a fan of Frank Lloyd Wright's innovative design, this is a nice plan in a doable size.
If you have a stream on your property with some drop in elevation or the potential for a small dam, there are many plans for producing your own small scale power, with low tech home built equipment.

Check out the contents page below, I think most people will find something of interest there, even today.
