16"diameter x 24" pitch made out of laminated epoxied wood, apparently
suitbale for human propulsion! Lots of complex mathematics and
formulas wonderful for endless disputes or alternatively gaining
enlightenment through the head-spinning method.

A hoax or for real? I couldnt decide, but worth a read anyway ;-)

What makes you think it's a hoax?

Nothing in particular... its just so easy to fake anything nowadays
that i find myself constantly skeptical ;-) having never heard of
anything like it before and not really having the background in marine
engineering im not really in a position to judge whether or not its all
true. it sure does look nice though!

Shaun

Now all Ive got to find is a nice link for building a wooden engine ^^

I recently saw plans and pictures of a plywood alternator.

I just realized that if you could find plans for the laminated engine
then the following is possible:
The plywood compressor is used to turbo charge the plywood engine that
drives the plywood alternator that charges the plywood battery....well
maybe not??.... that powers the plywood motor (modified alternator)
that drives the plywood prop. ...............Then put it all onto a
carbon fiber hull with digital electronics RADAR and all the latest
bells and whistles. ..... Oh well, cant make everything out of wood.

You're kidding me? a plywood alternator..... was it just a plywood shell
with the usual copper windings inside?

Shaun

It was a slow turning alternator that I think I remember actually had
greased wood bearings. It was large because the rotor was laminated
plywood at they had stuck rare earth magnets on it. Then there was
copper windings on, or course, plywood forms.

I think I found it with a google search .

it is very much for real and has been used in both human power and electric
power where low rev and high pitch are an advantage.

Shaun,

Read the entire posting - all four pages.

It's very real.
Can you think of a better way to create a one-off screw for a man
powered boat?

The only thing that is problematicis the section described is at a
single station and may not be the best choice IMHO.

--FWIW folks have also been making plywood laminated compressors for
small gas turbine engines, so sure, this is very believable.. ;-)
