Large flexible clear ball, twenty feet or so tall.
Lower half filled with water.
Motor boat in that water.
Reverse the motor boat, the water gets pushed to the front
of
the big flexible ball with a big wall of water in front of the
boat, one side is heavier so it rolls forward.
The
only reason this wouldn't work is if it didn't. When you're
taking water away from the back of the boat to pile it up in
the front, that side would "deflate" as well so I'm not sure if
this would move forward or just sit there.
Another thing you could do is just have a big water tight
hamster wheel looking affair with buckets on the inside. The
boat just sprays water into the forward buckets making the
front side heavier and rolling the whole thing forward.
Reminds me of a rather famous old discussion here...

cough... cough... goldfish bowl... |
|

I foresee problems relating to the exhaust fumes from the engine. |

//a big water tight hamster |
|
| |
You mean, they aren't watertight? Seems a bit of handicap dontcherknow? |
|
| |
// they aren't watertight? // |
|
| |
Sadly, no. No hamster has ever swum the English Channel, descended into the Marianas Trench, or won an Olympic medal in an aquatic event. |
|
| |
They are, however, very good for cleaning ink off dry-wipe whiteboards. |
|
| |
Put your flexible, clear ball of water within another less-
flexible ball of water. Attach the stern of the boat to the
inner ball with a strong bungee cord. |
|
| |
Now, accelerate the boat. As the bow nears the wall the
bungee begins to stretch, pulling the aft portion of the wall
inwards and moving that water forward. The bow touches
the wall, distending it and the temporary cavity created
fills with the surge. The boat, water and both spheres slosh
forward. |
|
| |
Maintaining this rhythm your boat should move over hill and
dale, hopefully to the nearest pub. |
|
| |
>No hamster has ever ... descended into the Marianas
Trench... |
|
| |
Don't be too sure about that. |
|
| |
Have you ever seen a hamster wearing an "I went to the bottom of the Marianas Trench and all I got was this lousy T-shirt" T-shirt ? |
|
| |
They'd have to 'ascend' to get the T-shirt. All they got was
those lousy cement shoes. |
|
| |
Presumably the cement shoes are provided by hamster gangsters. |
|
| |
//>No hamster has ever ... descended into the
Marianas Trench..// |
|
| |
// you could use a hamster as a guinea-pig // |
|
| |
Sure, if you were OK getting sued by guinea-pigs complaining about immigrant hamsters taking their jobs. Next, there'd be guinea-pigs rioting in the streets, other rodents would join in, pretty soon you'd have complete social breakdown, anarchy, looting, the collapse of civilization, and your world would be plunged into a new Dark Age, probably dominated by a Capybara elite. |

Well done, [Ian]. Really, you need to think your ideas through more carefully - you have no idea how much damage you could do. |
|
| |
Why not build a caterpillar boat? |
|
| |
First, imagine a giant tyre. Now stand it on its rim (ie, in the normal orientation for a tyre). Now fill it with water, up to the lowest point in the rim. Now put a boat in the water, and put a roller on the nose of the boat. |
|
| |
Boat thrusts forward, nose hits the inside of the tyre, pushes tyre, tyre rolls forward. |
|
| |
Yes yes, I know, physics. But still. |
|
| |
Don't you think you'll need a rudder? |
|
| |
Not if the boat is wide enough, shirley ? |
|
| |
Lower half filled with water.
Motor boat in that water.
You get in boat. |
