Nazi fuel
n.— «This expensive coal-to-liquid process was later used by South Africa to meet its energy needs during its isolation under apartheid. And now what some people refer to as “Nazi fuel” is back—thanks in part to high oil prices and lobbying by groups that stand to profit its use in the United States.» —“The Return Of Nazi Oil” by Frank O’Donnell TomPaine.com July 19, 2006.
