My questions about the data center are what kind-of climate controls they're using (not listed in the article) and how they're making sure that the generator and UPS are always in good condition. At my previous job we were able to correlate many component failures to poor climate conditions (too hot, too cold, too little humidity, too much humidity).

I also recall back in college setting up a 110 node linux cluster. Before they upgraded the HVAC system in the server room the cluster generated so much heat you the power cables started to shows signs of heat damage (we had to shut the cluster down until the HVAC was beefed up).

I've also had a bunch UPS where the batteries fail, and need to be replaced periodically. I also wonder how that figures into the cost of their data center (it's an issue at a big data center as well).

Ya, we faced battery failure problems. We are using standard cooling via Air conditioners. I think we will face more problems as we scale in this aspect, need to work out.

If you had wind and enough control of the building, you could funnel wind over water to cool, no power required. That was a method to make ice, a thousand years ago.

I love what you've done for so little cost.

We don't have sufficient control as we are in rental premise. Superlike your suggestion :)
