And before you suffer from a heart attack and throw away your POET shares, consider this again:

"One thing must be made clear: you won’t be able to replace your cell phone chipsets with subthreshold processors and throw away your smartphone’s charger anytime soon. Or do something like intensive image processing using only the energy collected by Psikick’s chips. “This won’t be possible,” the manager explains, “because you don’t get enough throughput. You’re not going to run these chips at gigahertz speeds. When you step down that subthreshold slope, you get a quadratic savings in energy, But the trade-off is that everything slows down. You’re going to run at a few tens of megahertz at most. That’s plenty to do EKG monitoring or vibration monitoring, but you’re not going to run, say, a high definition video on this chip."
