A wood burning car?
With rising gas prices ($6 in Florida tourist areas) the following story was too good to pass up. Pascal Prokop of Switzerland converted his Volvo to burn wood for fuel and got an operating permit from the Swiss technical inspection authority.
There are alternatives to fuel (and not just electric which costs money to charge up). The owner of a local restaurant runs his car on used cooking oil. He says the car always smells like french fries.
