And the battery runs on a... a chemical reaction.

Now they're all very practical visionaries.

A simple calculator for chemistry

We are huge packages of chemicals.

His invention gave birth to a new field of science, electrochemistry, and new technologies such as electroplating.

light things up.

Graphical utility for analyzing electrophysiological data

Where is it?

Electric cars run on electricity.

What we think we know, is that there's some kind of electro chemical communication between the roots of the trees.

But that's not the whole story, because there are signals, electrical signals, that travel along the branches of neurons and chemical signals that jump across from branch to branch.

And we wanted to take advantage of Moore's Law with electronic controls and software, and we absolutely wanted our car to be connected.

This is what we teach in the night schools.

I am studying electrical engineering at the University of Plymouth.

Telephone. Electricity.

And the part of the electric revolution that I want to focus on is sort of the golden age of appliances.

I'm an archeological geneticist at the Center for Evolutionary Medicine at the University of Zurich, and I study the origins and evolution of human health and disease by conducting genetic research on the skeletal and mummified remains of ancient humans.

Sal earned three degrees from MlT, a Bachelor's in mathematics, as well as a Bachelor's and a Master's degree in electrical engineering and computer science rounding out his education with a MBA from Harvard.

That's a generator.

You going to chem?

When these neurons interact, the chemical reaction emits an electrical impulse, which can be measured.

The air was infected with photochemical smog.

So if these letters stood for areas of interest, do you know what i mean?

Together, we decided to set out on two missions.

Power plant.

Salt water is a great conductor of electricity. 8th Grade Physics

The test has been applied in radio astronomy as well as in optical astronomy.

Electric irons are heated by electricity.

So I just have to bring the physics down to zero.

I found him a genius at chemistry.

Synthetic biologists are manipulating it.

I had trained as an electrical engineer and a physicist, and the first thing I thought about was, if these neurons are electrical devices, all we need to do is to find some way of driving those electrical changes at a distance.

Wires carry electricity.

This is a brain.

And so I find it interesting that instead of treating this disease by preventing exposure to the chemicals that promote it, we simply respond by putting more chemicals into the environment.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

Now I've taught you that battery science is straightforward and the need for grid level storage is compelling, but the fact is that today there is simply no battery technology capable of meeting the demanding performance requirements of the grid namely uncommonly high power,
