Hi guys, am looking to build a Tesla Turbine, or get one built - can anyone recommend a good  set of plans to work from?

Have any of you built a Tesla Turbine yourselves?

Thanks for your reply

Dan

You're talking about something like this right:

Works for me!  :)

Haha spot on, Dog-one! Planning to run the Tesla Turbine shaft with some kickass magnetic gearing from MGT.com.au (it's cheating a bit to use those, but they're seriously optimized and cheaper than parts + hours spent 're-inventing the wheel'), with the other gear mounted on my Mass Rotor (from 'contraption' post)

Had some great advice from a much smarter man than I, 'Mongrel Shark' on YouTube and moderator of G+ group 'Open Source Energy Research' - I think he may also be on this forum, too

Anywho, I've seen several quality youtube vids regarding op topic, want to take some 'tried and tested' schematics around the engineering firms here locally and get a well sealed Tesla Turbine made (or 2)

If you know any trusted resources that I can look into, that would be great (:

If not, the ones I do get hold of, I'll be sure to post up here

Cheers,

Dan

Ok holy crap dude, that is one Awesome product! Am definitely going to look into Cavitation Technology a bit further! ! Thanks for the link!

Search for Hydrosonic Pump.  There is a link to the original Griggs device on Rex Research.  Some claim the device is over-unity but of course the "self proclaimed scientists" say otherwise--I don't happen to trust those characters anymore.  Too many times when you dig deep enough you discover they are on-the-take from some energy company or foundation grant to discredit anything outside their purview.

But you see what I was getting at right, closed looped Tesla turbine with a Hydrosonic pump.  If both devices are very efficient and working properly, it should be possible to engage a motor just long enough for the system to stabilize, then disengage and let it run on its own.  I'm thinking the steam that exits the turbine should be run through a condenser and re-used, so even the water becomes closed-looped too.  If it works, you should be able to pull heat from the condenser to do whatever you want with.  If it turns out to be more than slightly over-unity, then you could probably pull some shaft power to run an alternator too.

The commercial Hydrosonic pumps are big suckers though.  I'm seeing on the order of 40 horsepower to run those things; that's almost 30kW.  You'd probably need one heck of a Tesla turbine to keep up with that unless you can utilize a gear drive to slow the shaft RPM and increase the torque to match the needs of the pump.  Seems odd to me that a big round block of metal with holes in it would need so much power to cause cavitation, but from everything I see, the cavitation causes intense drag, so maybe those numbers are pretty accurate.

Another thing you may consider, cavitation is supposedly a factor of a liquid being reduced to its vapor pressure.  So here's a theory of mine:  In a closed-looped system, what if you pull a vacuum on the water?  Wouldn't that allow cavitation to occur much more easily?  Then would you still need 30HP to generate steam?  See where I'm going with this?  By coordinating the internal pressure of the system, you would get something that works very much like a refrigeration system.  Get the right balance and it should be relatively easy to make it self running.  I would think the sweet-spot is where the turbine actually acts as the condenser, so you can toss that part.  You get steam going in, water coming out; now you can work with strictly mechanical energy and not heat.

Think of boiling a potato in the mile high city of Colorado verses a city close to sea level, which potato would cook faster or be done first? The one at sea level.
Water boils at 212 degrees F at sea level, in higher elevations water boils at a lesser temperature because of lesser pressures the higher you go.
The same would be true in a vacuum, lack of presser, hence one reason an A/C or refrigeration mechanic will pull a vacuum on the piece of sealed equipment they are working on, to pull the moisture out of the system, in a vacuum water turns to a cool vapor at a low temperature and can be removed easily. So I think you are right D1.  :cool::D:P

Which is why I asked once:  When running an engine on HHO, is it a good idea to let the engine pull a vacuum on the cell?  Never got an answer to that one.  Seems to me if there was any sort of resonance/vibration in the cell, the added vacuum might allow cavitation to occur, increasing production volume.  Remember all those folks talking about tuning their Stanley Meyer WFCs like a pipe organ?  I'm starting to wonder now...  I think maybe they were on to something.  If you pull a strong vacuum on the WFC and get it to ring like a bell by pulsing it or whatever, you very well might increase output considerably.

Apparently last years Tesla Tech Conference had all sorts of stuff on cavitation.  Anyone have some links to documents or videos on the subject?
