Agreed. In this early stage, though, I think the nanotech industry can be permitted momentary macroses of perspective.

However, if the nanotech sector manages to use magnetics or field manipulation in conjunction with a current in order to induce the fold (with some precision), and can keep the pathways (and the requisite etchers) tiny enough to allow the current to pass, successful micronization of both the assemblers, and the resulting constructions, to the nano level is foreseeable.

One may keep in mind progress (PDF) so far with nanomechanics (HTML).

IBM's recent work with atom manipulation could certainly assist in this endeavor, too.

Can Gallivan's folding limit equation be applied to a (yet undefined) function to measure the effectiveness of the successful folding of various materials? I would presume that different materials would exhibit different degrees of capacitance, resistance and all those other electricky *tances; different methods of folding (i.e. straight versus halved) may either modify, or be modified by, the material composition.

Mechanical engineer and Associate Professor of Mechanical Engineering George Barbastathis leads the charge into 'nano-origami' machines involving, the article reads, 'a new technique that allows engineers to fold nanoscale materials into simple 3-D structures' (more details available on MIT's page). The group had worked in 2005 with MIT Associate Professor Yang Shao-Horn to build a single-fold nano-capacitor (or see Google's HTML version), and this work appears to automate their 2005 process. A comment on the posted video appears to suggests this device is not completely automated yet, however. (This should not be confused with Paul Rothemund's slightly-more-ahead DNA-origami technology.)"

Incredible. Figure it'd be The Onion to bring the TRUTH to the front of the mess. I could not do the matter justice, alas.

From the article: "The system contains both a methanol fuel cell and a Li-on battery" and can "intelligently switch between power from the battery, fuel, or even both under high-draw circumstances." Sony intends to show off two models claimed to power your cell for a week or a month, respectively, as well as the latest developments with their sugar-batteries that can now run purely off your favourite cola beverage. This model builds on Sony's 2008 model, their first commercially-demonstratable prototype, and could make waves with Sony's OLED devices, but will Sony be able to avoid another battery recall?"
