We found rocks on Mars!

At just over 3,000 kilometres (1,900 mi) in diameter, Europa is slightly smaller than Earth's Moon and is the sixth-largest moon in the Solar System. Though by a wide margin the least massive of the Galilean satellites, its mass nonetheless significantly exceeds the combined mass of all moons in the Solar System smaller than itself.[10] It is primarily made of silicate rock and likely has an iron core. It has a tenuous atmosphere composed primarily of oxygen. Its surface is composed of ice and is one of the smoothest in the Solar System. This young surface is striated by cracks and streaks, while craters are relatively infrequent. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath it, which could conceivably serve as an abode for extraterrestrial life.[11] Heat energy from tidal flexing ensures that the ocean remains liquid and drives geological activity.[12]

Ganymede is the largest moon in the Solar System, making it a possible target for colonization. Ganymede is also the only moon with a magnetosphere. Ganymede is composed primarily of silicate rock and water ice. It is a fully differentiated body with an iron-rich, liquid core. A saltwater ocean is believed to exist
The satellite has a thin oxygen atmosphere that includes O, O2, and possibly O3 (ozone).[7] Atomic hydrogen is a minor atmospheric constituent. Whether the satellite has an ionosphere to correspond to its atmosphere is unresolved.[12]

Callisto is composed of approximately equal amounts of rock and ices, with a mean density of about 1.83 g/cm3. Compounds detected spectrally on the surface include water ice, carbon dioxide, silicates, and organics. Investigation by the Galileo spacecraft revealed that Callisto may have a small silicate core and possibly a subsurface ocean of liquid water at depths greater than 100 kilometers

Wouldn't that just replace one problem with another (depleting coal)

 

It would slightly reduce the impact of the current problem (depleting oil) and rush in the peak of coal.

But CTL is much more capital intensive than a normal refinery, none of which have been built in 30 years...

The future is that cars will be mostly powered by electricity in the long run.

How to Serve Alf

 

funny I just got an offer for a time share on that island just west of Olympus Mons

 

Not if you have solar panels. You could drive forever without a drop of gas or an ounce of coal.
