I hope land-bound pythonauts don't mind the water diversion, and only plan to
"swim" in calm water at a slower speed than on "slithering" on land, more like
this one fish vehicle, http://www.youtube.com/watch?v=iIdR0YsqYkc
However, if speed is desired, there is also plenty of wind power to pull
hydrofoil, like this one in Maui
http://www.youtube.com/watch?v=1oyWMusaDTI. The foil kayak pointed out is also
a great achievement with arm power. The legs have much more power than arms,
if we can find a way to apply it...
For long distance, Greg probably has gone far... (http://adventuresofgreg.com)
