Winegrapes are an ag commodity … More Think Like an Economist: Marginal Vs. Total Thinking … More Think Like an Economist: Marginal Vs. Total Thinking

Nanotube Capacitors As Battery Substitutes?

June 9, 2006

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 … More Nanotube Capacitors As Battery Substitutes? … More Nanotube Capacitors As Battery Substitutes?
