Petroleum/Fossil fuels – Ever since my buddies in Jr. High in the 1970’s were lighting their farts on fire, I’ve known that poop has been an untapped source of energy.  I’ve always wondered why we were making our youth put their lives on the line for oil?  Attached is a pic a taxi in 1917 with a bag of gas for it’s fuel.  Whether this was coal gas or street gas (biogas) is irrelevant.  The point is that since 1917, we could have been cleaning biogas with charcoal and running it in our engines!  Zero Americans needed to risk their lives for oil!  Contact cliffsmedley@gmail.com if you want to get fossil fuels out of your life!
