2. 2 | Wind and Water Power Programeere.energy.gov VIVACE Technology

3. 3 | Wind and Water Power Programeere.energy.gov Purpose, Objectives, & Integration The VIVACE converter is a transformational technology. It taps into a vast new source of clean and renewable energy, that of water currents as slow as 2 to 4 knots, previously off limits to conventional turbine technology that target rivers with water currents greater than 4 knots. The vast majority of river/ocean currents in the United States are slower than 3 knots.

4. 4 | Wind and Water Power Programeere.energy.gov Technical Approach 1.Increase the conversion efficiency from hydrokinetic energy to cylinder kinetic energy. 2.Increase the conversion efficiency from the cylinder kinetic energy to electric energy generation. 3.Perform open water testing on an improved VIVACE system that will incorporate the improvements obtained from objectives 1 and 2.

5. 5 | Wind and Water Power Programeere.energy.gov Plan, Schedule, & Budget Schedule Initiation date: 9/1/2010 Planned completion date: 12/31/2012 Budget: Planned and actual budget are tracking very closely 15% of project budget expended as of August 2011 Budget History FY2009FY2010FY2011 DOECost-shareDOECost-shareDOECost-share $146K$110K

6. 6 | Wind and Water Power Programeere.energy.gov Accomplishments and Results VHE designed and is currently fabricating its next generation power takeoff (PTO) unit. The new PTO will incorporate lessons learned that improve hydrodynamic efficiency as well as conversion efficiency from hydrodynamic to electricity.

7. 7 | Wind and Water Power Programeere.energy.gov Challenges to Date The most prevalent challenge has been software development for the power takeoff unit. VHE’s design process makes provision for several software iterations, culminating in a laboratory test at the U of Michigan Marine Hydrodynamics Lab

8. 8 | Wind and Water Power Programeere.energy.gov Next Steps Laboratory testing of new PTO expected in November and December of 2011 and January 2012 Open water testing in the St. Clair River, at Port Huron, MI is scheduled for spring / summer 2011
