brucey -

I've always imagined an uphill/downhill commute where I had jugs of water on the downhill run. The water or ballast or whatever would be "delivered" at the bottom of the hill. On the uphill run the car would be empty. That would make for a net MPG gain.

The trick is having a situation where the cargo is "useful", aka doing something important like making $ for me or ???
