Re: Can you power a car on baked beans?

Yes, you can power a car on baked beans.

Several ways come to mind.

Dry them and burn them to raise steam to power a steam engine or a steam turbine.

Convert them, by steam reforming, to town gas (carbon monoxide and hydrogen) and use the 
Fischer-Tropsch reaction to convert the town gas to a liquid fuel, that is equivalent diesel to fuel.

Use the water shift reaction to convert the town gas product to carbon dioxide and hydrogen and 
feed the hydrogen to a fuel cell.

Feed the beans to a beast of burden and use the beast of burden to pull the car.

Ferment them to produce a combustible biogas.

I suggest you Google on “steam reforming” and biogas.
