Ethanol
=======


Ethyl alcohol or ethanol (C2H5OH) was the fuel used for the 
`German V-2 rocket <http://www.astronautix.com/v/v-2.html>`_, 
and the first derivative rocket engines in the United States, 
Soviet Union, and China. Although abandoned for many years, it has had some
resurgence as an environmentally friendly fuel.
