Coal Oil - Basis June 8th 2019
Tights	Coal distiller is not sustainable way to create oil. It is easiest way to create replacement to drilled ground oil. Production cost with 2019 coal ton  prices was around $13 / barrel. Market price was $60.

Science forwards all the time. One week after original release coal and coal plants came back to fashion as weapons against drought, possibly also against climate change. The original throw out release used 100% coal in the examples. The samples were recalculated and downgraded to checked plant coal.

From one coal ton you get ... app. 2-4 oil barrels. The number of barrels per ton depends on the coal-hydrogen ratio. Coal which is used in plants has 30-50% CxHx compounds. One coal ton has 300 to 500 kg CxHx compounds. Oil barrel weighs around 129 kg. From one ton clean coal you get around 7 barrels oil

Coal distiller

In the picture there is diagram for process, with what you can extract oil from coal without chemical catalysts.

When you warm the coal in CO₂ furnace, with electric resistors, you can raise the heat as high as you wish.
The actual fuel-coal in the furnace does not set into fire without oxygen.

After you have vaporized CxHx from plant coal, you lead the gas into cooler.
In cooler you lower the gases temperature below 200C. 

From the cooler you can lead the gas into common distilling tower ... with standard 0.2 % fee from the distilled products.

You can recycle CO₂ back to furnace from cooler. Alternatively you can feed new oxygen free gas into furnace all the time.
You can convert common air into oxygen-free CO₂ + H₂O gas with fire.

Required temperature in furnace can raise to over 2 000 C.
Temperature is dependent on the material into which CxHx is bound to.

For 1 kg you need around 1 kN power + leaks. For 2 tons need 2 - 20 MN.

10 cents / kWh converts to 0,00278 cents / second. When so, the heating cost is around 0.02 cents for 7 barrels.
If you need 2 tons for one ton, 7 barrels costs around $100. Which goes to $13 barrel.

For 81 million barrel daily production, you need 23 142 857 tons coal in 24 hours.

With 10 MN per 2 tons, you need 4 821 GW plant power.
In yearly level this goes to 1 800 TWh production.  Half from EUs / USAs current power production capacity.
When one coal train carries 100 000 tons coal, you need 230 train loads per day.

The earlier $13 price can never come true in wide scaled conversion ( without sugar oil as primary source ). $13 is possible in small scaled conversion. 
If you have coal, but not oil on our soil, oil from coal is essential in wars and war time scenarios.

Basic demand for the super smarts is the unlocking of the Future and Fast packs.

World's coal reserves are big, but limited. Oil from coal is temporal, short term solution.
Not very easy to get the required R&D licenses.
