And what if we could get exquisite control over the essence of energy, the electron?
Six and a half years later, a hundred and eighty researchers, they have some amazing developments in the lab, and I will show you three of those today, such that we can stop burning up our planet and instead, we can generate all the
energy
we need right where we are, cleanly, safely, and cheaply.
A tremendous amount of
energy
is coming at us from the sun.

energy
into an electron on a plastic surface that you can stick on your window.
We want to talk about storing energy, and unfortunately the best thing we've got going is something that was developed in France a hundred and fifty years ago, the lead acid battery.

energy
to do something, to actually become dynamic, as we'll see here.
Oil droplet forms through self-assembly, has a chemical metabolism inside so it can use energy, and it uses that
energy
to move itself around in its environment.
