Make Your Own WEC!

Offshore renewable energy should be fun too!  Researchers in Oregon, USA have developed a simple working model of a wave energy converter (a direct drive linear generator) that you can make at home with your kids! Actually, it looks like the kids can make it by themselves:

The device was designed as part of a teaching curriculum. For more, including paper instructions and how to make the project into a full-fledged science experiment, see the article by NNMREC:

UNH-RVAT baseline performance and near-wake measurements

The Reference Vertical Axis Turbine (RVAT) experiments were tidal turbine tests conducted “with a 1 m diameter, 1 m tall three-bladed vertical axis turbine in a towing tank” by Peter Bachant and Martin Wosnik of the Center for Ocean Renewable Energy at the University of New Hampshire. For more info, see their paper.

They have released a repository on GitHub, which contains the processing and plotting code, as well as the derived data set from the UNH-RVAT tow tank measurements performed in Spring 2013: github.com/UNH-CORE/RVAT-baseline

UNH-RVAT Reynolds number dependence experiment

Researchers, Peter Bachant and Martin Wosnik,  of the Center for Ocean Renewable Energy at the University of New Hampshire  “investigated—experimentally and numerically—the effects of Reynolds number on the performance and near-wake characteristics of a 3-bladed cross-flow turbine” For more info, see their METS paper.

Their are releasing the processing and plotting code, as well as the derived dataset from the UNH-RVAT Reynolds for free on GitHub: github.com/UNH-CORE/RVAT-Re-dep

 

NNMREC Open Data Project

awec Open Data is here! nnmrec.oregonstate.edu/open-data The US Northwest National Marine Renewable Energy Center is hosting data from physical tests for the marine renewable energy research community. Sharing experimental data is a great way to increase the impact of your research and gain wider recognition for your work. Already there are data sets from Autonomous Wave Energy Converter tests in the OH Hinsdale Wave Lab at Oregon State University and from a University of Washington Micropower Tidal Turbine. Bret Bosma, the project’s founder said this: “The motivation for the site is to allow researchers and developers to be able to share their data to foster collaborations and advance the industry.” Great idea Bret!
