The battery has run out of power.

We extended this idea. We tested it many times over, and the next version we came up with was a box that kind of could trickle charge on solar energy, but most importantly connect to a car battery, because a car battery is a ubiquitous source of power in places where there's not enough electricity or erratic electricity.

Power goes into a battery. There is a custom made computer that tells the camera when to fire.

So when you talk about expensive power, the cost per kilowatt hour to supply battery power to something is on the order of two to three hundred pounds.

Here's another example. Chris, you're the source of all power.

The battery died.

Battery is low!

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.

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?

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.

This all came from a professor waking up at night to the third night in a row that his wife's cellphone was beeping because it was running out of battery power.

For example, power plants can adopt solar energy or capture and safely dispose of the carbon dioxide they produce with fossil fuels as can large factories. Automobiles can be engineered for much greater mileage through hybrid technology combining battery power and gasoline.

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.

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.

And I started looking at how we could build battery back up systems that could give people five hours, 10 hours, maybe even a full day, or three days' worth of back up power.

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.

We could therefore achieve huge reductions in CO2 emissions by converting to small, lightweight, battery powered vehicles running on highly efficient electric motors and charged by a low carbon energy source such as solar power. Even better, by shifting to electric vehicles, we would be able to use cutting edge information technology to make them smart even smart enough to drive themselves using advanced data processing and positioning systems.

Their torch is meant not to light the way, but to inflame the hatreds that are their only source of power.

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.
