That's awesome if it occurs.  But just like the original Moore's Law, you
never know when they'll hit technical or physical limitations.

Thanks for linking to this.  My appreciation for Google never stops
increasing.  One gigawatt is a lot of power, though the article wasn't too
specific.  Is Google planning on generating *all* of it's power needs plus
excess to sell to others?

Yeah, I've already seen this.  But it's one of those articles that make me
wonder, most of it is hype.  It's an article about a prototype so it's sort
of wait and see.

Alternative energy is just starting. You ain't seen nuthin' yet!

I hope so.  But I think one thing to consider is that the population is also
increasing exponentially, and so are living standards and the amount of
energy used per capita.
