Nanotube Capacitors As Battery Substitutes?

Lynne Kiesling Check out this very cool idea for reinventing capacitors with nanotubes to provide energy storage for portable devices. The capacitor, a 300-year-old technology for modulating current flow by storing small amounts of energy, stores energy via electrodes that separate a charge and thus maintain potential. But it can only store energy in proportion …
