You know, standardized platform with the motors and the battery when it operates, little solenoids that will lock it in place and get low voltage power.

For them to get a battery that goes 120 miles is an extension on range, not a reduction in range.

Danger! High voltage.

For this test, I bought a voltage tester.

This makes sense only for systems that are larger than a kilowatt of peak power and that have sufficient battery capacity. Local systems in one building could be connected to local low voltage DC or 230V AC grids to improve the security of supply.

The battery died.

Battery is low!

A residential solar power system consists of just three components the PV modules, a battery storage unit, and a charge controller. Such a system can supply low voltage DC electric power at five volts for mobile phones, and 12V for LED lighting, pumps for outdoor use, and electrical appliances such as computers and televisions.

This motor has enough power to take you up the hills of San Francisco at about 20 miles per hour, about 30 kilometers an hour, and this battery, this battery right here has about six miles of range, or 10 kilometers, which is enough to cover about half of the car trips in the U.S. alone.

We have a little battery and on this little battery that computer will run for five years without needing replacement.

It's odd. It has a battery.

My phone is out of battery.

What is the cost of that battery?

The battery has run out of power.

Battery powered, it is silent and rarely noticed.

You drive. You take your depleted battery out.

And so, this stuff is like battery acid.

I warmed the battery up in my armpit.

The battery of my MP3 player was empty.

You don't reset, or recharge your battery every time.

The most expensive thing is the battery inside this.

A full battery comes on. And you drive on.

The battery in this sense, is the crude oil.

But the crude oil is replaced with a battery.

This is the only part that's battery backed up.

Some can also be connected to the car battery.

They took the basic ingredients, put them in a single jar and ignited them and put a lot of voltage through.

The battery is not the gas tank, in a sense.

Hawaii you can drive around the island on one battery.

One of the key issues was battery consumption and charging.

But we've put a long life battery backup on here.

Now, here's how you do the battery and the bulb.

The car won't start because the battery has run down.

And so through a process of selection evolution, we went from being able to have a virus that made a crummy battery to a virus that made a good battery to a virus that made a record breaking, high powered battery that's all made at room temperature, basically at the bench top.

If you have a battery, it costs five cents to make it.

And that battery went to the White House for a press conference.

On board are also a battery, a computer, various sensors and wireless radios.

This assets management company held shares of Panasonic, the battery manufacturer of Tesla.

And so what if you could grow a battery in a Petri dish?

Now this is a high powered battery that we grew in my lab.

We looked at the question, what happens when the battery is disconnected from the car.

We have a battery bay. It costs the same hundred dollars as the gas tank.
