Second, the concentrated energy is introduced into a vertical 

 chamber in a manner to create an enormous fluid flywheel. This 

 fluid fl3rwheel provides a continuous power output from waves that 

 are spaced apart in time. 



Third, the system does not impose energy transformations and 

 hence the inefficiencies of energy transformations are eliminated. 



Fourth, and last, kinetic energy from the ocean wave is extracted 

 by a simple turbine which can have a one shaft drive to the load 

 device such as an electrical generator. 



Lockheed has built and tested a model to demonstrate proof of 

 the concept. We regard it as a nominal 1/100 scale model. The test 

 model was built as a proof-of-concept demonstration. Each compo- 

 nent has not been anal5d:ically optimized, but the model demon- 

 strated very encouraging qualitative results. 



A more complete description is contained in a technical paper 

 which has been published and I have attached the paper to this 

 statement for reference purposes. 



Your committee has devoted much effort to OTEC so I believe it 

 would be of assistance to you for me to make some comparisons 

 between OTEC and wave energy. 



ENERGY RESOURCE LOCATION 



OTEC, tropical latitudes, worldwide. 



Wave Energy: Middle to higher latitudes, primarily west coast of 

 land masses due to the Earth's rotation. 



DEVELOPMENT WORK 



OTEC, funded Government studies since 1974; technology work 

 underway; total system demonstration by mini-OTEC last summer; 

 firm plans for large scale pilot plant. 



Wave energy, Lockheed Co. efforts since 1975; Government 

 funded work began in 1980; (Great Britain has had a large, active 

 program for several years). 



POWER OUTPUT, FULL SCALE SYSTEM 



OTEC, lO's and lOO's of MW per plant. 



Wave energy, a few MW at most per plant. 



Our discussion of wave energy, and DAM- ATOLL more specifical- 

 ly, would not be complete without addressing the issues relating to 

 the commercialization of this technology. To a large extent, suc- 

 cessful market introduction of new energy technologies requires 

 close cooperation between the private sector innovator and the 

 Federal Government. 



As DAM-ATOLL technology progresses from the research and 

 development stage through demonstration to market introduction, 

 varying specific needs must be met. Fundamental to determina- 

 tions of the appropriate roles for the private sector innovator and 

 the Federal Government in addressing these needs are two param- 

 eters: 



Potential economic benefits to the public and private sectors; and 



Risk inherent in the successful commercialization of the subject 

 technology.
