It would be fun to build a lightweight streamlined bus that is all rowing machines inside hooked to generators that feed a motor that drives the bus.  There is a battery, but that is to smooth things out and does not store much.  Only the driver does not row.  Twenty or so hard rowing passengers could get it to highway speeds.


More fun that this was.  Same basic principle.  This is a must watch clip.  It is a hoot.  Riding the Greyhound, 2050's style.  Add an overhead rack like air-plains have for carry-ons.  Row the friendly inter-states united.  There will be no first class.

* When I had the youth 'Ben Hur' had in this scene, I met the man. 
Later he would be the one to say: "it's not soylent green, its people!" <-- same guy.

That will be about 12 - 15 years after this clip was made.
