[Roger Rabbit]

Just a write up that MSM Money has done about different fuels..

I like the one about Hemp

You might be eating these potential power sources, putting them to other uses or throwing them away. But they could potentially power your car.

Dance floors that produce energy:

"Okay folks, the next three songs promise a free drink for every large
person who gets out on the floor and gets on down with it!"

Cars that run on chocolate:

"I got stuck in traffic today and the car started to overheat,
and I rolled down the window, and now I feel a combination
of naughty and satisfied somehow..."

Algae:

"Roy got in early on in a big scum market play and made out like a bandit."

Brewery waste:
Assuming waste production lags beer output, we will have to find some folks
sober enough to run the power plant.

Gizzards and Guts:
Here in MO, a lot of people eat these, and I suppose this
makes them energy hogs.

Dirty Diapers:
Little John was an absolute gold mine until his Aunt Sally
wrecked everything and potty trained him while on a visit.

Yeah I know, solutions are tessellations of many things, but some of these
sources are a bit out there. I didn't touch on the manure wrinkle since
it would walk on my IP for a bovine fart compressor device to be fitted
to our dairy herds, and used in a secondary market as a kicker to the brewery
waste energy play by involving the end user in the process.
