00:00Who has the greater thrust?
00:02The question of all questions, who has more power?
00:06Here we have the ultimate comparison between the two most advanced methane engines in the
00:11space industry, Raptor 2 from SpaceX and BE-4 from Blue Origin.
00:18Two completely different philosophies, but both with a clear goal.
00:22Maximum performance at minimal cost.
00:24In terms of thrust, the engines are about equal, with the BE-4 delivering a bit more
00:29power at sea level.
00:31240 tons versus 230 tons for Raptor 2.
00:38When it comes to ISP or efficiency, the Raptor is clearly ahead.
00:42With 350 seconds in vacuum, it's more efficient than the BE-4, which reaches 330 seconds.
00:49That means the Raptor gets more energy out of the same amount of fuel.
00:53But it should also be clearly stated that Blue Origin did not optimize the BE-4 for operation
00:59in a vacuum, but rather for use in the atmosphere.
01:02That's why ISP isn't everything.
01:04Things get really interesting when it comes to chamber pressure.
01:07You know what?
01:08Things get really nice.
