Directory:Balkee Tide and Wave Electricity Generator
From PESWiki
Under patenting process, TWPEG has a unique Energy Conversion Device capable of converting Tides and Waves motion directly to rotary motion to turn a generator always in the same direction. TWPEG is scalable in size depending on sea depth, from knee deep water to any reasonable depth, provided there is some waves.

Seeking Development Assistance
In Sept., 2006, the inventor, Raj Balkee, said:
- "Presently I am alone in this project. And in a third world country like MAURITIUS, it is not easy. I am looking forward to collaborate with any individuals, groups and companies, whatever be their interest. In fact I would like to hear from anybody who has something to say about my invention, TWPEG. Please contact me or email me at the address given below."

Variant of Salter's Duck
On Oct. 2, 2006, a person from the Tidal industry offered the following comment to be presented anonymously
(lightly edited)
To the inventor’s credit he has actually built a functioning device. Granted it is a low budget effort and consequently unrefined. However, it shows some promise as a micro scale niche market device.
This TWPEG is a variant of the old Salter’s Duck device and like the Salter’s Duck (http://www.google.com/search?q=salter%27s+duck) faces the difficult challenge of getting vertical action of the wave converted to useful rotating mechanical torque and does so with the use of a ratcheting mechanism (weak link as these are not designed for anything but very slow rotations). The main reason why the Salter’s Duck never floated was likely due to excessively high tooth loading exceeding material limits and that will be problem here as well. The inventor might consider a Scottish Yoke mechanism as a more efficient method to deal with the problem.
Wave and tidal resources have two very distinct hydrodynamics: tidal is generally the full water column, and wave is the surface action.
I have some difficulty seeing the TWPEG being of any value in converting tidal action into useful power.
No Particular Advantage

Tidal energy will be insignificant compared to the wave energy. There are so many marine hydroelectric methods of comparable value. This one has no particular advantage that I can see.

Perhaps a later, more effient model run in series with others could provide energy for remote coastal locations. Portable units could be used for vacationing or stowed in emergancy kits on boats for 24/7 power.
With all new technologies of this type they only need to find their niche. Keep up the good work!
Rebuttal
On Oct. 2, 2006, Congress:Member:Sterling D. Allan, responded:
Yes, tidal energy has great potential. That is not what is being disputed. The point is that the mechanism of harnessing that energy needs to be optimal. There are a good number of good mechanisms that have already been developed, which are further along in their progress. We would not want to discourage this particular approach, for it may hold promise as one of the contending methods. It's still too early to compare it fairly, though.
NEW DEVELOPMENTS upto January 2008
Since the posting of the invention, it has undergone several changes in design to cater for patenting exigencies, because elements in the original design were not taken a being novel by the patent office. Further more a small artisanal portable working prototype has been built and tested with a 30w dc motor and it lights a 10w lightbulb in a one feet deep water. The prototype can be tested by anyone at any time.
THE KWH OUTPUT OF TWEG IS PROPORTIONAL TO ITS SIZE, WAVE HEIGHT AND SEA DEPTH. A MINIMUM KWH CAN BE EASILY ACHIEVED IN A NEAR-SHORE WATER IN ANY COASTAL COUNTRY WITH ONE TWEG. WITH AN ARRAY OF TWEGS THE POWER OUT CAN BE FORMIDABLE IN MEGAWATT.
