asked the Secretary of State for Energy what is the annual layout of the United Kingdom and Japan upon their joint venture on wave energy; and what are the comparative figures for the United States of America.

The United Kingdom, United States, Canada and Japan agreed a three-year collaborative programme of work to develop wave power air turbine generating systems in April 1978. The Republic of Ireland subsequently joined the programme. The centrally funded part of the programme will cost 140 million yen—approximately £320,000. The individual contributions are approximately equivalent to:

Canada	£55,000
Republic of Ireland	£34,000
Japan	£77,000
United Kingdom	£77,000
United States	£77,000

In addition, the United Kingdom Government agreed to contribute one of the two turbines associated with the project—the other being supplied by the United States Government. For the United Kingdom turbine a £265,000 contract was placed with a United Kingdom firm.
