Poo-Powered Rickshaw Unveiled At the Denver Zoo 52
novenator writes "Today the Denver Zoo has unveiled the world's first poo/trash-powered motorized tuk tuk. The vehicle also boast a gasification system designed by the zoo itself. From the article: 'The tuk tuk was purchased from Thailand and then re-designed to run on gasified pellets made from animal droppings and waste generated by the zoo's staff and human visitors, according to The Denver Post. The poo-powered tuk tuk is the second prototype The Denver Zoo has put together to show off their sustainable energy system -- the first? A blender used to mix margaritas at a zoo event.'"

Step 1: burn combustible materials like dried wood, dried yard clippings, and/or dried animal droppings to produce carbon monoxide gas.
Step 2: direct carbon monoxide gas into combustion engine where it acts like any other combustible gas with the right fuel/air/compression mixture.
Step 3: drive around with trollface on because you aren't paying gas taxes while getting rid of a bunch of yard clippings you would have let decompose in your backyard or bagged up for the trash man.
It is carbon neutral unless you are using oil-based fertilizers all over your lawn/trees. Otherwise decomposing would have released any trapped carbon anyway.
