Fun with Tech: Solar Powered Websites

I've been reading Low Tech Magazine for the past few years. I'm interested in their deep research and thoroughness of the articles. I'm generally interested in seeing if the "modern way of life" is substantially better in every aspect than the past or other alternatives.

A bit over a year ago, the magazine started a solar-powered web server. They've just published their results so far. It's interesting how a kernel upgrade cost them availability due to power usage.
