Analysis of the proposed system show that it will be necessary to increase the blade lengths substan8ally in order to achieve a reasonable energy capture with the device. An example show that increasing the blade length from 1 meter to 5 meter increases the energy capture from 2.5 % to 21.7 % of the incoming energy. Analysis using a typical near shore wave climate (Karmøy scaDer diagram) gives a yearly production in the range of 150 MWh for a turbine with 5 meter long blades. The torpedo with the two turbine blade rings, counter acting generator kept away from the active wave zone is an interesting solution and addresses issues related to extreme loads and wave energy conversion without direct contact with the waves in an elegant way. A nice feature of the system is that it is easy to retrieve and maintain by simply disconnect and bring to shore. It is difficult to assess the economics in the project before more detailed analysis/engineering has been carried out but given the innovative solution it is our opinion that it is worth looking into.
