This is an abstract for a poster to be presented at the
Fifth Foresight Conference on Molecular Nanotechnology.
There will be a link from here to the full article when it is available on the web.


The concept of a buckyshuttle [a buckyball C60 confined but mobile in a short (10,10) nanotube segment] emerged recently as a possible two-state element, with the C60 located at one or the opposite end of the tube. A triangular array of such elements, if ever made, would have a maximum capacity of almost 1018 bit/m2. The van der Waals forces are responsible for the potential wells at the ends, and for the friction on the way between them. We will analyze the feasibility of this idea, the energetics, kinematics (when switched between 0 and 1), and thermodynamic efficiency [1].
