I recall your telling the story back when the Enron experience
was fresh in California and we had seen our electrical bills
go up by an order of magnitude.  I am very glad that I wasn't
trying to power a Cray.  At least transputers were
microprocessors not those big water cooled Cray systems.

I recall I was once shocked to read how high a percentage
of the energy we use and resulting in the global warming
goes to power PCs.  I have a half dozen of them cranking
away 24/7 on long calculations at the moment but at least
most of them are laptops.

Best Wishes
