Right.  Maybe running of a bunch of photo-voltaics would have been more hydrocarbon friendly (if not market grabbing), but the machine is more peak-efficient (there is little benchmark data out there) per watt than Blue Gene by my calculation, more balanced than Opteron (not than a Cray), and has a very cool custom interconnect.  It takes some baby steps in the direction of "many-core" with more and simpler cores than the current generation of x86-64 chips.  If it is possible for custom machines to regain traction in this space, I think SiCortex's systems are the best bet.
