1. 1 | Program Name or Ancillary Texteere.energy.gov Water Power Peer Review River Devices to Recover Energy with Advanced Materials(River DREAM) Brent Crenshaw Bayer MaterialScience brent.crenshaw@bayer.com 412-777-7421 9/21/2011

2. 2 | Wind and Water Power Programeere.energy.gov Purpose, Objectives, & Integration Purpose To develop an entirely new non-invasive concept for hydroelectric energy generation in free flowing rivers based on an electroactive polymer (EAP) generator and a galloping oscillator Objectives: Develop, design, and model a galloping oscillator Characterize and model a dielectric generator Create a system model to evaluate potential for energy harvesting by combining the two models

3. 3 | Wind and Water Power Programeere.energy.gov Technical Approach Technical Approach: Develop understanding of dielectric generators and galloping initially and create computational models of both systems Combine models to evaluate energy harvesting potential of integrated system Key issues being addressed: Low efficiency of conventional turbines in free flowing rivers and streams Need for “out of the box” alternative method of energy harvesting

4. 4 | Wind and Water Power Programeere.energy.gov Technical Approach Unique aspects of approach: First time galloping has been studied for energy harvesting in water environment Novel use of dielectric elastomer generator in river energy Galloping and dielectric generators appear complimentary to each other since both work naturally at frequencies compatible to those attainable from free flowing rivers and streams No danger to aquatic ecosystem from fast moving blades

5. 5 | Wind and Water Power Programeere.energy.gov Plan, Schedule, & Budget Schedule Initiation date: June 2011 Planned completion date: Oct 2012 –Subcontracts were not in place until Sept 2011 Milestones for FY11/12 –Galloping Oscillator Construct test bed and model oscillations from lift curves Design/construct galloping oscillator Create model to estimate energy harvesting potential Model prism shape change in static and dynamic conditions Create desired morphing shapes –Dielectric Elastomer Generator Model EAP in Matlab ®, PSPICE ® and COMSOL ® Measure characteristics of EAP generators Model EAP in energy harvesting setup Budget: Due to delay in subcontracts being signed spend rate is significantly under budget for FY11. Should be as planned from Oct 2011 on. * There is no cost share yet because our indirect rates have not been approved yet. Therefore, we have only been invoicing direct costs.

6. 6 | Wind and Water Power Programeere.energy.gov Additional Slides The following slides are for information purposes only

7. 7 | Wind and Water Power Programeere.energy.gov Guidelines for number of slides (Not a template slide – for information purposes only) Because of time constraints, lower TRL level projects (shorter term and smaller award amounts) will be introduced and briefly presented by DOE staff, though project PIs will be responsible for providing project background material and slides. Presentations for these projects will be allotted only 5 minutes per project, therefore please provide no more than 5-6 slides. Slides may include pictures, graphics, or information that is additional to what is requested in the template (above), however, slides must include all information that is indicated in the template. Project PIs will also be available for Q&A with the Peer Reviewers (via teleconference) during the timeslot allotted for the lower TRL level projects.

8. 8 | Wind and Water Power Programeere.energy.gov Preparation Instructions (Not a template slide – for information purposes only) Do not include any proprietary, copyrighted, or confidential information. Do not mark any slide with “Official Use Only” or any similar restriction used by your organization. Please name your electronic MS PowerPoint presentation file as follows (use the first 4 letters of your title): [Title_Organization_LastName.ppt]. Do not incorporate animations or special effects since all presentations will be saved as PDF files for presentation and for posting on the web. Animations critical to describing the project may be presented as separate files, however they must be approved by the Program and presented within your allotted time.

9. 9 | Wind and Water Power Programeere.energy.gov Final Instructions (Not a template slide – for information purposes only) Your presentation, in MS PowerPoint format, is due to Ed Eugeni at Edward_Eugeni@sra.com by September 27 th. If your presentation is too large to email, contact Ed Eugeni at 240-223-5552 for alternative delivery options. Reviewers will be receiving your presentation prior to the meeting. In order to supply adequate time for the reviewers to review your material prior to the meeting, you MUST submit your presentation by close of business on September 27th. Your project is subject to a score reduction penalty if you fail to meet this deadline.
