Where we’re at
~40 projects 500,000 active participants
growing slowly mostly geeks?
Computing power: about 2 PetaFLOPS About 8X a $300M supercomputer

Conclusion
Science needs much more computing power Volunteer computing can provide it
and maybe avoid Dark Ages II BOINC: the enabling technology How to grow from 0.5M to 50M volunteers?
