So is it the shape that allows you to make the engine so flexible? And if it's not, then what is it?

It's, it's kind of a combination of factors.

So again, I like to say we, we bring together a lot of proven strategies that reduce or eliminate sources of loss, and we're able to pack all of that into one elegant, simple geometry.

If we're to lay out in, in a piston engine what are the categories of loss, let's say, you're going to have your thermal losses like within the combustion chamber itself, heat loss to the walls of the combustion chamber to the piston crowns.

You're gonna have your thermal losses in the exhaust 'cause ultimately your combustion, your reaction progresses.

It has a limited time for that to happen and then by the time you've, you know, burned all of your reactants, well essentially you have a heat release in a confined space which is gonna result in a rise in pressure and that's going to do work on the pistons, it's going to move them.

Once they have traveled to the end of their stroke, there's still a substantial amount of heat in the engine, something like 600, 700 degrees of your exhaust temperature, and then that all leaves out the exhaust valve, [laughs] right? You- it leaves your combustion chamber but there's still energy in that gas, in that, you know, reacted fuel.

Am, am I getting that right?
