@jorendorff @gvwilson isn't 53 kilojoules ~.0147 kilowatt hours? So yeah I'm way off... But after plugging in the construction and operating costs I'm sure it's not going to look good.

The big mistake is ignoring initial costs; how much energy did it take to get the GPU from silicon to inside the rack, etc.

But we can argue about if it's one cup of tea or one hundred. Our electricity bill is up 16%. The planet is still burning.
