I'd like to add my vote here for Orson Scott Card and John Wyndham. My son who is now 13, enjoyed "Ender's Game" and "Ender's Shadow". John Wyndham's novels may start a bit slow for a young reader. In this regard "The Kraaken Wakes" is one I found hard to get into as a child. The "Midwich Cuckoos" or "The Chrysalids" are two that I would recommend, although some background explanation of the latter might be necessary for someone born after the Cold War. "The Day Of The Triffids" is perhaps, a bit dark. His short stories are great if you can find them.

A lot of modern sewage works use the methane to run the heaters that keep the digestion process going. Sometimes they use it to run modified IC engines that power generators. The heat from the engines is then used to heat the digesters instead of using a standard radiator. There is at least one plant in the UK that has used this system for over ten years.

No, Propane is a longer chain hydrocarbon that liquifies more easily. Natural gas is mostly methane that requires much higher pressure and/or lower temperature to turn it into a liquid. Fine for an ocean going tanker. Not really practical for a road vehicle.
