BTW, how's everyone with the fact Yllendthyr would use biodiesel?
Technically the equipment were more or less already there, especially if I have fairies make my filters.
The fact there was a great interest for biodiesel in the 20s and 30s.
Basically my colonies would be filled with seemingly endless plantations which will be delivered to large plants.
In WW2 Germans used coal to gain J2 fuel so it could work.
Perhaps I might be blending it with mineral diesel when the latter is in sufficient stock.

I've actually never heard of biodiesel until now, and at a glance it doesn't look so abnormal. What exactly is so odd about it?
