12. NNMREC Tidal Micropower Helical Turbine Generator Support Frame  Oceanographic measurements are fundamentally power limited  Integrated energy harvesting could provide 10-20 W continuous power  Modular alternative to cabled observatories

13. NNMREC Rivers and Constructed Channels  Potential for power generation from in-stream turbines installed in the fast-moving waters downstream from Columbia River dams  Incremental environmental impact should be very small  In-stream turbines for flow control and power generation as potential alternative for energy- dissipating sluice gates

14. NNMREC Deep Water Offshore Wind  WA and OR: 300 GW resource  Floating platform technology required for deep water  Platforms can be built and systems assembled in WA and OR  PPI currently installing full-scale demo unit off Portugal  Initial study on environmental impacts and permit streamlining for PPI Wind- Wave Float technology completed by UW-NNMREC UW and OSU PIs currently responding two 2 major funding announcements by US DOE

15. NNMREC Conclusions ■ Marine energy Centers are developing capabilities to move technology from concept to commercialization. ■ Need for broad and sustained partnerships between Centers, industry, and public stakeholders. ■ Opportunity for universities to solve challenges and to train the first generation of marine energy engineers.
