I mean, the fact that we're allowed to pipe combustible gas into our homes and then light it on fire.

- 我的意思是，我们被允许将可燃气体输送到我们的家中，然后点燃它。

If you try to start a fire with damp wood, or fresh wood that contains a lot of water, heat will boil the liquid water into vapor, which isn’t a combustible gas.

如果您尝试用潮湿的木头或含有大量水的新鲜木头生火，热量会将液态水煮沸成蒸汽，这不是可燃气体。
