The guys at Penn State have built an efficient hydrogen still. In a
new table-top reactor, bacteria from wastewater produce abundant,
clean hydrogen from cellulose, or even vinegar, and a little
electricity.

The press release suggests that hydrogen produced from cellulose and
other renewable organic materials could be blended with natural gas
for use in natural gas vehicles.

"We drive a lot of vehicles on natural gas already. Natural gas is
essentially methane," says Logan. "Methane burns fairly cleanly, but
if we add hydrogen, it burns even more cleanly and works fine in
existing natural gas combustion vehicles."

Round up some microbes and hit the road.
