Today, it takes 100 picojoules to do a double precision floating point operation, but 4200 picojoules (42 times!) more energy to move that data from RAM to your registers.
This is a fascinating observation. As one of pg's essays asks, "what do you know that know that no one else knows?" [quoted from memory]. It sounds like this is your answer. Interestingly, it's not literally that no one else knows it -- it's that no one else (AFAIK, of course) has factored it into their designs, as doing so probably requires more-or-less a clean sheet.

When I re-read this post (http://blakemasters.com/post/22866240816/peter-thiels-cs183-startup-class-11-notes http://blakemasters.com/post/22866240816/peter-thiels-cs183-...) and thought about what our "secret" really was, I decided to include that fact in our presentations and it finally started to "click" for people... technical folk and investors alike.
