Alright, so I'm intrigued. But oh, the history...
The Fischer-Tropsch technology, discovered by German researchers in 1923 and later used by the Nazis to convert coal into wartime fuels, was not economical as long as oil cost less than $30 a barrel.
The fuel that comes out of the Fischer-Tropsch method (also used by South Africa during their embargo years) burns cleaner than current fuels, stripping out sulfur, arsenic, and other nasty byproducts. [quoting from both the article and Kos]
Nazi Germany and apartheid South Africa. Now there's a nice set of play mates.
