- Ever heard of coal tar? How about the history of dye chemistry? How
- about alcohol as a chemical feedstock (and coal gasification and ...)
-
- Coal is every bit as usable a chemical feedstock as oil. Oil is
- cheaper and more convenient for many feedstocks, but you can turn
- coal and coal oil into just about anything you can turn oil into.

- Flat out wrong. Reword it to 'we would have to pay a bit more for
- a lot of our plastics,' etc. and you have a true statement.

-
- Then think again. Rayon is made from plants. You can get most
- plastics et.al. from an alcohol feestock and enough manipulations.
- Where can you get alcohol from? Natural gas, plants, coal, pig shit,...

- As someone from a solar lab, I would have expected you to be familiar
- with the chemical feedstock potential of plant material.
-
- Yes, it is very easy to get long chain hydrocarbon feedstocks from
- oil. Yes, it takes a bit more manipulation to get them from coal
- and plants. No, it would not be the end of plastic society as we
- know it if oil went away.
