Alternative fuels for rail transport

Post by Pensyfan19 »

It's that time again!
I recently found an article which discussed using a new type of aluminum-air battery for rail transport. Anyone have any thoughts of what can be the most efficient energy source for running trains as we are constantly running out of fossil fuels?

Sorry in advance if you do not agree with my opinion.

a battery is a storage device, it is not a source of energy .
If Conductors are in charge, why are they promoted to be Engineer???

Huh. I heard that myth most of my adult life, and it seemed every time someone said "we'll run out in the next 20 years", there was some form of discovery of petroleum reserves that pushed the timeline back another 20-30 years. Now, nobody even talks about running out.

There will eventually be cost and production break-thrus in biofuel (e.g. algae based diesel and jet fuel are already a thing but not yet cost competitive) which might see shifts away from petroleum based diesel, but I'll go out on a limb and say for North America, we'll be using internal combustion engines for the foreseeable future.

Well, petroleum is a storage device, too, for energy that originally came from the sun and was absorbed by ancient plants.

Constantly running out? How often is it that we run out of the fuels you speak of?
I see that there is currently a supply of such fuel equal to the vast worldwide demand, so after each case of running out, some miracle must have occurred to restore the supply. Clearly, we rely on such miracles. Therefore, to ensure their continuation a shaman must be stationed at each power plant. Let's hope that the miracle supply doesn't require a shaman at every substation.

Technically an alternative fuel for rail transport. :wink:

Meh, that's just appeasing the activists...

Guess where all that hydrogen comes from today? Most of it comes from natural gas....
