Is there a grinder?

Because the bus has a grinder.

The trash system has like a compactor and then the sand tanks have filters and those filters do clog up.

So there's very strict requirements about what you're able to put into the toilets.

Because ultimately, if you put something that's not going to go through the filter, some poor dude has to go down there and get it out.

That's right.

Diarrhea.

So there's two different ways that you can empty the sand tanks.

They can either get pumped out.

That tends to take a little bit longer, and it's a little bit louder.

So submarines are trying to stay quiet.

And the other way you can do it is you can pressurize the tank with high-pressure air, and then just open the hull valve, and high-pressure air pushes everything out into the ocean.

I'd like to see that.

The key with that, you absolutely positively cannot open any inside drains because then the inside becomes the path of least resistance.

You have several hundred pounds of high-pressure air.

Yeah.

And if you open up the drain valve to your toilet, it's just going to go back up to the toilet.

That's your path of least resistance.

Yeah, yeah, like a geyser.

That's right.
