  2. VIVACE Technology

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

  5. 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

  6. 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. 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. 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
