00:00How does our explosive donut compare to the proven rocket engines?
00:05Let's take a look at the competition. Aerospike engines.
00:10These clever engines automatically adapt to the ambient pressure.
00:15So, in theory it's ideal at sea level and in a vacuum. Don't ask me why it hasn't been used
00:22more widely yet. Full-flow staged combustion. The current gold standard for efficiency.
00:29SpaceX's Raptor engine uses this technology. Highly efficient but complex and expensive to manufacture.
00:36Blue Origins BE-4 is also a staged combustion engine. But it's a bit different and less
00:44complicated because it only has one preburner instead of two. Gas generator cycle. The old reliable.
00:52Relatively simple, proven and robust. But not as efficient as more modern designs.
00:59Now here it comes. Our RDE comes along and changes the game. It promises up to 25% more efficiency
01:07than conventional deflagration engines. That's like getting every fourth tank of gas for free.
01:14can we get every half of that thing?
01:15…
