Ever find a source for that cooking oil that is supposed to be so plentiful?
Is that why you are looking at steam?

There was a Car & Driver article I believe about 20 years ago about Bill
Lear's steam car. It worked, it ran, it was fast and everything, but in
order to achieve this, it had steam tubing through all the body panels. One
fender bender and the driver would be covered in live steam and cooked like
a lobster, I seem to recall. But it was a long time ago, I might be
wrong...
