the other hand, construction of wind generation facihties at sea 

 would probably be more expensive than land-based facilities. 



Has the Department examined that potential trade off to deter- 

 mine whether or not it makes economic sense to talk about wind 

 generating farms on the ocean? 



Dr. Katz. The wind program has looked at that, and at least for 

 now the trade off appears to make a lot more sense to develop and 

 deploy wind systems on land than it does to build the platforms it 

 would take to support them at sea. 



Mr. Studds. Have you consulted the resident enthusiast of the 

 University of Massachusetts on that? 



Dr. Katz. The resident enthusiast at the University of Massachu- 

 setts has excellent contact with the Department of Energy's wind 

 program. 



Mr. Studds. Good. 



Are you responsible for those grants a month or two ago to study 

 the feasibility of wind power generators on Nantucket and in Pro- 

 vincetown? You had better say yes because I am going to thank 

 you. 



Dr. Katz. Undoubtedly. 



Mr. Studds. Undoubtedly, very good. Continue that fine judg- 

 ment. 



One other thing. The discussion of potential OTEC sites has 

 focused to date so far as I know primarily on areas of the oceans 

 where there is a sufficient temperature difference between warm 

 surface water and cooler deep water. 



Would it not also be possible to use the OTEC technology to 

 generate electricity from the temperature difference between ocean 

 water and hot water from wells drilled in the Continental Shelf, 

 and do you have any assessment of the magnitude of hot water 

 which could be reached by wells drilled in various parts of the 

 Outer Continental Shelf? 



Dr. Katz. Forgive me if I sound bureaucratic, but I have to start 

 off that way. The geothermal energy people 



Mr. Studds. Oh, good. Is that another energy department? 



Dr. Katz. Sorry about that — work for the Assistant Secretary for 

 Resource Applications and are responsible for looking at the assess- 

 ment of geothermal resources. However, we do recognize the possi- 

 bility that OTEC technology could work between such temperature 

 differences, and we have been, that is, our ocean people have been 

 talking to the geothermal people about that and we are working on 

 a resource assessment of the warm water that would be available 

 there. Perhaps Mr. Richards can give us some more detail on that. 



Mr. Studds. What happens when an ocean thermal resource 

 converges with a geothermal resource? Do we have an interdepart- 

 mental coordinating committee established? 



Dr. Katz. It is called level mixing I think. 



Mr. Studds. It is called what? 



Dr. Katz. Mixing, mixing at various levels. 



Mr. Studds. As long as it is not interfacing, we can put up with 

 it. 



Did you want to add to that? 



Mr. Richards. Typically the resource map should be done by the 

 end of this fiscal year. They will be top level resource maps that
