The optical rectenna, you could think of it

as like a radio antenna, only for the sun.

It's working off of very similar principles,

And when that energy is coupled into the antenna,

then another device is used to extract the energy

So making a rectenna is actually a pretty simple process,

which was part of the beauty of the discovery.

You basically take any type of conductive substrate,

like a carpet-- vertical off the substrate.

to create a so-called metal insulator or metal diode

And so that diode structure is important,

because it's the fastest diode in the world.

And it's the only diode that's fast enough to open and close

the gate at the speed of solar energy oscillating

What gets me excited today is that we've done it.

That we've actually achieved the goal that

But that's enough to get me out of bed every day,

are twice as efficient of what we have today.
