Can you and all the other YouTubers STOP POSTING things like this that imply this is about to change the universe. You aren't dumb but you are acting dumb. Rolls Royce, GE and others had the hydrogen issues in the engine all beaten back in the mid 1990s. So why haven't there been any hydrogen powered airliners? No engine will be any sort of "game changer" so long as there isn't a fuel supply.

@MrJturner74 Why only flying wings? They are a jet engine they can be used in anything that's suitable AND that can carry the fuel. Liquid Hydrogen is a incredibly hard to use - ask NASA.

@Stupidityindex Yeah the dimming thing is real and we know that from 9/11, but I doubt we could rely on it as any sort of mechanism to tackle the subject. We just must stop pumping carbon into the atmosphere at the levels we are and start massively increasing the mechanisms that suck it out of the air and sequester it in the ground. The planet can handle a lot but not this much. We just have to stop burning coal in power stations period and there are alternatives. Just for start the Chinese could flip all their coal fired power plants to gas fired with cheap Russian gas. That alone would be a massive hit to emissions.
