I am fascinated with the Royal-Enfield Bullet diesel. The 100+ mpg one cylinder diesel motorcycle, from a 50 year old design, is still manufactured in India and is probably the sole transportation for some families there.

The Diesel Bullet is a lean machine that some in more economically evolved nations are using as a platform to innovate and satisfy their own desire for energy independence.

Riding on Salad Oil - A guy in Germany, where over 50% of the new cars registered are efficient clean diesel technology, has retrofitted an old stripped Enfield with a Yanmar L100 diesel engine (Chinese clone) engine.
