Yes, but tech has improved a tad since then.
In every flight you take, the wings are filled with highly combustable materials, and yet we find ways to keep them from exploding. The same is true for all those batteries in electric cars, and of course gasoline.
- xxpor 5y agoJet A is really not that combustible; it's very close to diesel/kerosene. If you take a lit match and drop it in a bucket of Jet A, nothing would happen, it'd just burn out. It's way safer than gasoline. It's combustible only when turned into a fine mist. On the other hand, H2 would have exploded just from the spark of lighting the match.
- jsight 5y agoYou'd likely get by with dropping the match into gasoline most of the time too. Its not definite that there will be vapor from it in the right mix for it to catch fire before hitting the surface. Gasoline also isn't quite as combustible as people imagine.
- nostromo 5y agoIt's worth noting that hydrogen fires burn bright and quickly, but tend to not be very dangerous to people. Gasoline and batteries are heavy and tend to stick to surfaces (including people) when they burn, almost like napalm. Hydrogen rushes upwards, away from people and surfaces, as it burns, and is generally quickly exhausted.
- linuxftw 5y agoI strongly disagree with this statement.
- jsight 5y agoI'm not sure what there is to disagree with. Fire around gasoline is dangerous for a number of reasons, but liquid gasoline pooled just isn't as volatile as people imagine. The vapors are different. See both sides of this coin here: https://www.youtube.com/watch?v=DsZOE1nvlhI https://www.youtube.com/watch?v=DsZOE1nvlhI Also, this: https://www.youtube.com/watch?v=vln5-HZpgcA https://www.youtube.com/watch?v=vln5-HZpgcA Don't try this at home. Vapors can change things dramatically and horribly. The videos lightly demonstrate this too, but it can be worse.
- linuxftw 5y agoLiquid gasoline without the present of vapor is pretty much nonexistent. Dropping a match into some is going to be a problem.
- throwaway0a5e 5y agoIn my experience the combustibility of det fuel and similar petroleum products depends primarily on whether the context of the conversation is praising modern safety engineering or heckling someone for using diesel as a cleaning solvent.
- jandrese 5y agoIt would be more dangerous when spread over a large surface and allowed to vaporize.
