So why don't you update me on where you guys are now?

Yeah.

And I'll actually take a step back and I think talk a little more about the history of this technology, because I do think it's interesting and why you're seeing this need to industrialize today.

But nuclear batteries are not new.

This is what NASA used to power all of our deep space spacecrafts.

This is what's powered its missions to the lunar surface, Mars, to Saturn, to Pluto, left our solar system, the Voyager spacecrafts.

The U.S. Air Force and Navy have used these as well in the 20th century to power maritime buoys and Arctic sensors.

Tell me about that.
