In chapter 11 of the Mysterious Island, Gideon suggests that Earth's coal deposits will run dry by 2150, and that water will become mankind's next fuel. What do y'all think of this?

Hi,
This is a good example of Verne's predictions that became real. Of course, there are other renewable sources like solar and wind, but Verne's idea of water as a future fuel was a really good idea, and it shows how creative he was. Using water hints at hydrogen fuel, which is gaining traction today.
About the coal deposits... eh.. it's hard to predict when they will run out. Coal consumption has dramatically dropped compared to the past, making it even more difficult to estimate the exact timeline.

It takes more energy to split water into hydrogen and oxygen than you can get back by recombining them (the second law of thermodynamics is a bitch) so even if you are making hydrogen from water, you need some other source of energy to do it. At best hydrogen can be used as a way to store and transport energy, and outside of a few specialized applications, there are generally better ways to do it.
