Turbine Design Team

John Van Dixhorn (ME, 2021): Turbine Design Team Lead, Generator, Electronics  | (949) 212-6365 | Linked In

Van Dixhorn PortraitGrowing up in Southern California, John Van Dixhorn graduated from San Clemente High School knowing that he would enjoy learning and developing skills towards having a career in Engineering. Entering Cal Maritime as a freshman, John knew this university would give him the opportunities towards a favorable career path.  He started attending CWC meetings as early as sophomore year but really started applying his knowledge and skills to assist the 2020 team with some deliverables, specifically the dynamometer and root strength test.  The part that interested him was how the whole project would include all of the core classes that engineering students must take.  The most valuable aspect for being part of this competition is the Department of Energy’s effort to teach everyone involved what the renewable energy industry looks like.  Now as a Senior, John’s hope after graduating would be to take his skills and knowledge gained from Cal Maritime and apply it to an ever changing and growing industry that has a real world impact.  With that, John can’t wait to enter a career in renewable energy generation.

Project Role:  Being the Turbine Design Team Lead, John Van Dixhorn works closely with Dr. Nordenholz and all members of the team to ensure smooth operation of the skill building, design process, and manufacturing process.  More specifically to the team though, he will be working on the generator and electronics side of the turbine system.


Toby Barrons: (ME, 2021) Generator Design | Linked In

Barrons Bio PictureToby Barrons is a senior Mechanical Engineering student at Cal Maritime. He is from Orinda, CA where he graduated from Miramonte High School. Toby enrolled in the Mechanical Engineering program at Cal Maritime in order to apply his early interests in physics and mathematics to real world problems. His passion for developing solutions to engineering problems lead him to the Cal Maritime Collegiate Wind Competition Team in his junior year, where he worked with fellow student, John Van Dixhorn, to build a dynamometer test platform. Through the CWC Toby hopes to expand his knowledge of the renewable energy industry and further develop his skills in delivering finished products from theoretical designs.

Project Role: As a member of the generator design team Toby is responsible for designing and manufacturing a turbine generator to capture power created by blades across a wide range of wind speeds. Generator development requires rigorous application of electromagnetic theory, circuit design, and additive manufacturing techniques. In this capacity, Toby works closely with John Van Dixhorn, the Turbine Design Lead, and the projects Electronics Adviser, Dr. Evan Chang-Siu.

Matthew Morganstein (ME, 2021): Mechanical Design | Linked In

Morganstein Bio Picture

Matthew Morganstein is a senior Mechanical Engineering student at the California State University Maritime Academy. He is from Discovery Bay, CA and graduated in 2017 from Liberty High School in Brentwood, CA. Ever since he was little, Matthew was always curious about why things functioned the way they did and how design related to function. This fueled his interest in engineering. Matthew chose to pursue his degree with CMA because he was interested in the small class sizes and hands-on opportunities. Being an Eagle Scout, Matthew has a strong passion for preserving the environment through the use of clean, renewable energy. Joining the CWC team was a perfect way for Matthew to earn fun and valuable hands-on experience in designing machines that contributed to his passion. He enjoys the blend of theoretical and practical knowledge that this opportunity presents and is very excited to see what comes from this journey.

Project Role:  As a member of the mechanical design team, Matthew works very closely with his partner Reagan Hesse in designing and manufacturing the variable pitch mechanism, passive yaw system, and nacelle. Together with Cal Maritime’s head machinist Mr. Long, Matthew will be manually machining and using a CNC to produce the aluminum components of the wind turbine.

Rosenberger Bio PicAlex Rosenberger is a senior Mechanical Engineering student at Cal Maritime. She is from Roseville, CA and enrolled in Cal Maritime after graduating from Del Oro High School in 2017. As a freshman, Alex was very excited about the hands-on curriculum offered as Cal Maritime and was drawn to the CWC team due to its connection with the Department of Energy. During her junior year, Alex worked under the senior design team to learn the basic concepts behind the development of a wind turbine under the specifications of the CWC competition. Alex hopes to learn more about renewable energy and how to use her ME degree to improve energy efficiency and sustainability after graduation.

Project Role: Alex is a member of the Blades team and will analyze, design, and manufacture the wind turbine blades for the competition which involves an extensive knowledge, and application, of fluids and aerodynamics. She is working closely with Blades Team Member Gillian Hooper as well as PI Dr. Nordenholz in the development and production of the turbine blades.
