hmmm...

they were also building - in the early days - on electric trolley
tech.  hydrostatic has also been tried, but it wasn't as successful.

yup.  but biodiesel doesn't handle low temps well; b20 - 20% bio / 80%
kero - is the best you can run in the winter around here.

you can't liquefy it at room temps; that's why they talk about 3000psi
tanks, or cryogenic.  and that has its own safety issues.

definitely the best next step, right now.
