Invisible Solar Nano Cells Promise Clean Energy

An anonymous reader writes "ZDNet is reporting that Harvard scientists have developed a silicon nanowire 200 hundred times thinner than a human hair that crank out up to 200 picowatts. Charles Leiber from Harvard University, who devised the technology with colleagues, is quoted: "An individual nanoelectronic device will indeed consume very little power, but to do something interesting will require many interconnected devices and thus the power requirement — even for nanosystems — can be a challenge". Conventional sources, he added, are "bulky, non-renewable and expensive" by comparison."

TFA was for Dora the Explorer club, and not /.

I think this article was meant for Dora the Explorer club, and not /.

The journalist is either completely clueless or trying to make it comprehensible for kindergarten. The result is so wrong and incomprehensible that it is worthless: ...The cable itself looks, like the cables used to hook up cable television networks...But the similarity stops there...Incoming light generates electrons in the outer shell, which are then swept into the second layer and the inner core along micropores. These "holes", as they are called, carry an equal, but opposite, charge as electrons, which means that the two particles move in opposite directions in the presence of an electric field.
