<div>Mark ,</div>
<div>Yes the subject we are really discussing is the friction losses of water in contact with a surface. there is a formula for water horse power, all to do with velocity and surface area .</div>
<div>The theory that a large slow moving piston made of water, has less friction loss of a metal piston sealed with rings. and it's ultimate connection with the out side world is in question.</div>
<div>Or that a column of water being ejected from the rear end of a vessel has an advantage over other propulsion sytems.when compared to more sophisticated methods And is especially relevant if it can be obtained with exploding Mond gas.</div>
<div>Say pyrolysis of sea weed.</div>
