Supercapacitors are able to store vast amounts of energy in very small packages, Nano Ultra-Capacitors (colloquially, NUCs), by comparison, have ten times the energy density of gasoline.  In 2045, the Texas company EES perfected the nano ultra capacitor cell sufficiently dense to an entire single family home in a package the size of an aspirin tablet.  Almost as significantly, these cells could be completely charged or discharged in ten microseconds.  In 2046, engineers at the University of Cape Town, in a landmark experiment, demonstrated that all of the electrical energy in an atmospheric lightning strike, over five gigajoules, could be absorbed in an array of these cells.  Copyright note: EEStor is a company working currently in super-capacitors of barium titanate.  EEStor is a company based in Cedar Park, Texas, United States that claims to have developed a capacitor for electricity storage, called the ‘Electrical Energy Storage Unit’.
