They've invented the Flux Capacitor.
Ok, so they call it a Memristor, but read what it does:
The memristor is formally defined as a two-terminal element in which the magnetic flux Φm between the terminals is a function of the amount of electric charge q that has passed through the device. Each memristor is characterized by its memristance function describing the charge-dependent rate of change of flux with charge.
That, to me, is a flux capacitor. And others think so as well.
Flying Deloreans and Mr. Fusions can't be far behind.
