A completely self sufficient home in my opinion is the ideal. The ecocapsule is a good start similar to how the Tesla was a good start toward the electronic car.

The ecocapsule is a good investment because it's mobile, it's moderately self sufficient, it's only drawback is it's not cheap.

Distributed generation and self sufficient homes are really one of the only long term paths to economic independence.

The ecocapsule can generate it's own electricity. It can capture and clean it's own water from rain. And can generate from wind. It still needs to be perfected though.
