Cool, and green tech from IBM

Very cool story about a water-cooled IBM supercomputer at Swiss university ETH Zurich. It uses 40% less energy than air-cooling the same system, and the captured heat is used to heat the building. Amazing how retro-innovative we become when we start thinking of resources as gifts instead of entitlements.
In my house, we've been separating items out for recycling pickup for years. They take glass and some types of plastic. And recently, at my wife's encouragement, we found a cardboard recycling drop-off by a neighborhood school and have since been removing all cardboard from our trash and dropping it off for recycling. Some of my neighbors fluff it off with the old "it's not worth it for the cost," or "my little bit can't make a difference." But the truth is, worth is subjective. It's worth it to me because I know every little bit counts, and it just feels like I'm being more grateful for what I DO have by going a little out of my way to recycle that cardboard.
As far as it making a difference, it certainly does in my trash load. Separating out the cardboard has cut my trash output in half! It just amazes me how much less trash we produce. And of course, unshredded cardboard takes up a lot space, and who shreds their cardboard? Maybe our load has become even lighter because we buy a lot of things packaged in cardboard boxes instead of plastic. And nine people go through a lot of breakfast cereal. But cutting down on plastic packaging and recycling seems, to me, smarter every day when you see the result of plastic in the environment, the oceans in particular. Next, I may run some water pipe behind my flat screen TV. There's enough heat coming out of that baby to power at least one shower a day!
