Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

A memristor is a passive two-terminal electronic component for which the resistance (dV/dI) depends in some way on the amount of charge that has flowed through the circuit. When current flows in one direction through the device, the resistance increases; and when current flows in the opposite direction, the resistance decreases. When the current is stopped, the component retains the last resistance that it had, and when the flow of charge starts again, the resistance of the circuit will be what it was when it was last active.

Memristor theory was formulated and named by Leon Chua in a 1971 paper. Leon Chua is to circuit theory as Einstien is to relativity. Thirty-seven years after he predicted the memristor, a working solid-state memristor was created by a team led by R. Stanley Williams at Hewlett Packard. Here's an informative video of R. Stanley Williams giving a keynote presentation on memristor technology at the UC San Diego Center for Networked System's Winter Research Review 2010.

In 2009, Massimiliano Di Ventra, Yuriy Pershin and Leon Chua co-wrote an article extending the notion of memristive systems to capacitive and inductive elements in the form of memcapacitors and meminductors whose properties depend on the state and history of the system.

Insanity is doing the same thing over and over again, and expecting a different result.

God will confuse the wise with the simplest things of this world.  He will catch the wise in their own craftiness.

Memristor simulation is possible with the Falstad Circuit Simulator.

HP abandoned memristors and took it off their roadmap for their super computer "The Machine".  Everyone else has been focusing on ReRAM but I think the jury is still out on if this is just another memristor variant (HP wants to say it is so the millions they flushed down the drain on Memristors didn't go to waste). Intel is now focusing on 3D Xpoint although very little is known about it and based on what has been released it looks like another CBRAM variant that is apparently 1000x NAND and higher density then DRAM.
