I think I found the problem, assuming... this ship runs on tiny little batteries.

(Video) Guy I might get one of those.

This computer runs on batteries.

Batteryoperated pith helmet, with fan.

I hope for a solar battery car.

I want a car that runs on solar power.

This toy car runs on batteries.

And you can do it the same, over and over again.

And computers don't go to sleep.

(Laughter)

Basically, by controlling the genes, you can control multiple materials to improve your device performance.

It is convenient to carry, assemble, and launch by hand.

This is a new kind of solar cell that's based on how a leaf works.

And we've all heard of charge.

Battery's the power source.

So something I think is very fascinating is

Phone's dead.

These are motorized devices that are controlled by little electrical signals from your muscle.

It doesn't work so well because the batteries are running down.

It doesn't work so well because the battery is low.

The battery is flat.

battery dead.

Oh, shit, man. Your battery's dead.

Took a few photos. I got my satellite phone out.

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

We call this our sushi circuit. It's very popular with kids.

My battery dead.

Crap, it's burnt out.

Roaming drains the battery. All right.

This is an overview of the solar cell prototype.

And the next six months of my life were the hardest time in my career, trying to design, build and deploy out in the field these 25 time lapse cameras.

This battery is charged.

Batteries must be running down.

Three of the four cells are gone.

You forgot the batteries?

Lithium. Like camera batteries. Odd.

The battery.

So that's kind of the vision that I've been thinking about.

Either the battery's dead, or her cell got damaged somehow.

(Music)

May I have some camera batteries, please?

Please give me batteries for a camera.

Typically, these things are put in the ground.

We wanted something that was really affordable.

I'm looking for batteries.
