The internal combustion engine is not sustainable.

So this is our internal combustion engine for creativity.

What about the internal combustion engine, which was invented in 1879?

The internal combustion engine took off because weight mattered, because you were moving around.

As a matter of fact, I invented the combustion engine and the twoway nappy.

But after the Stirling engine, Otto came along, and also, he didn't invent the internal combustion engine, he just refined it.

If you put that same fuel in an internal combustion engine car, you get about 20 percent efficiency.

It's not good stuff, and it's from inefficient combustion, not from combustion itself.

Oxygen is needed for combustion.

So it's the same idea as a jet engine, it's just the heat source was the reactor rather than the combustion of fuel.

and we're making great progress for this goal is to have a propulsion system based on hydrogen and fuel cells, designed and validated, that can go head to head with the internal combustion engine we're talking about obsoleting the internal combustion engine and do it in terms of its affordability, add skill volumes, its performance and its durability.
