With more than 50% of the nation's population living within 50 miles of coastlines, we have vast potential to provide clean, renewable electricity to communities and cities across the United States using marine and hydrokinetic (MHK) technologies. To help this emerging industry develop new models and tools that improve the design, development, and optimization of MHK devices, the Energy Department's Water Power Program kicked off the Open-WARP (Open Wave Analysis and Response Program) Challenge. A collaboration with NASA's Center of Excellence for Collaborative Innovation (CoECI) and Harvard Business School, Open-WARP is a software coding competition that will draw on the expertise of members of TopCoder, one of the world's largest community of programmers, to develop a computational model for calculating the response of a wave energy converter (WEC) device to waves with given heights and periods. With support from the Energy Department, TopCoder will run Open-WARP, which consists of a series of contests broken up into two phases and four milestones that will enable hydrodynamics and device components to be simulated in separate modules. Coders can win cash prizes for each of the different milestones. In the challenge, coders can show off their skills in several topic areas, including conceptualization and data analysis.
