Interesting that Google was in the news earlier this week investing in renewable energy in part to deal with the mounting energy costs related to their datacenters.
http://www.nytimes.com/2007/11/28/technology/28google.html?_r=1&oref=slogin SAN FRANCISCO, Nov. 27 - Google, the Internet company with a seemingly limitless source of revenue, plans to get into the business of finding limitless sources of energy. The company, based in Mountain View, Calif., announced Tuesday that it intended to develop and help stimulate the creation of renewable energy technologies that are cheaper than coal-generated power. Google said it would spend hundreds of millions of dollars, part of that to hire engineers and energy experts to investigate alternative energies like solar, geothermal and wind power. The effort is aimed at reducing Google's own mounting energy costs to run its vast data centers, while also fighting climate change and helping to reduce the world's dependence on fossil fuels.

I don't understand what you hope to gain on the Linux/390 list. Linux on zSeries is not the answer to all computing problems. Indeed, it's the answer to a relatively small class of problems, and that class tends to be very heavily-weighted towards high-density consolidation. It is very rare to find a justifiable case for Linux on zSeries without the z/VM hypervisor (and, correspondingly, quite a few Linux virtual machines). If you're running a single Linux image, your zSeries machine is a very, very expensive way to do that. I am of course biased. As David said in the interviews that have been floating around on YouTube, we're not doing the OpenSolaris port to run on the metal, we're doing it to run under z/VM. This is largely based on watching the Linux-on-s390-and-z experience, in which an awful lot of development effort has been spent to ensure that it will run on the metal, and the return on that effort is pretty minimal, as there's little justification for running Linux in an LPAR rather than on z/VM. We chose the easy and obvious solution for OpenSolaris: it requires z/VM, period. If your objection is "but I threw away VM and now I have to buy it again", well, a) it's rather cheap compared to the cost of a lot of stuff for z/OS, and b) I will try but fail to repress my schadenfreude as I say, "Maybe you shouldn't've thrown it away in the first place, then." It's hard to tell what your objection is, though. Escalating cost of the data center? I assure you, Google has to deal with this. One of the lessons to be learned from z/VM is that after a while it costs a lot more to power and cool and manage and babysit a bazillion discrete servers than it does a few zSeries boxes. That's sort of the point of this whole consolidation exercise.
