Hannes,
 
I looked at the website which has the following quote
 
"...The technology chosen was that of a floating barge on which the machinery would be mounted to supply about 3 mega watts of power to the local community...."
http://www.panzapath.org/mambilima-project/
 
and a picture of an apparent slow moving river.  What is the velocity, and how do you expect to develop more than 4,000 horsepower at the site? 
 
One hp is 550 ft-lbs/second, so if the river was travelling at 5.5 feet per second and the barge turbine generator was 50% efficient, then the force on the barge mooring lines for 1 hp would be 200 pounds, or for 4,000 hp would need to be 400 tons, plus the drag on the barge hull.  Sorry, there is something wrong with this picture.  I hope you don't disappoint the locals and turn them against alternative energy.
 
Bob

Well shucks guys.
And their I was, thinking I was contributing something useful to the
group.
Sorry to get all your heckles up.

Maybe the Engineering School at Copperbelt University should have taken
this group's collective expertise, wisdom and opinions into account
before they selected our technology as the most suitable for their
Mambilima community project
<http://www.panzapath.org/mambilima-project/> in Zambia, and maybe the
consulting engineers at a couple of governments who looked into our
technology before approving the project funding and who have some
experience with hydro power just got it all flat wrong. Maybe the Energy
and Environmental Partnership and the Development Bank of Southern
Africa's engineers and advisors should follow the group's advice and
hold on to their wallets too. Please see more information on our NPC
website here: http://PanzaPath.org <http://PanzaPath.org> . Oh, and by
the way, we did not sell them snake oil, we have donated a license for
the use of the technology, and have over the past year thrown in much
much more. All on condition that the school for the handicapped, the
medical clinic, library and churches get free electricity for "life".

I don't think I will post here again soon, maybe just a short note to
let the group know that they can check on some pictures on a website in
a few months. And no, we won't publish our proprietary data in this
forum. We preserve that for potential licensees who need to do due
diligence and test a demo model before we accept payment for a license.
If and when they become a licensee, they would not appreciate that kind
of information to be available in the public domain either.
