BluSource Energy

Engineering firm BluSource specializes in alternative energy, marine applications and high-strength, light-weight composites for diverse uses ranging from dirigibles to yachts.

The engineers on the Czero team were proactive problem-solvers from our first introduction. They quickly applied the full breadth and depth of their engineering team’s impressive intellect to determine the most efficient and cost effective system to maximize the energy-harvesting capabilities of Brown’s concept.

They were remarkably objective in their trade studies to find the best solution, favoring a simpler mechanical solution over their greatest strength: advanced hydraulics. They walked us through potential failure modes of each system, and educated the team about the pitfalls of component scalability. In addition to their technical solutions, Czero did an excellent job conveying their thought process and analysis to the Brown team with clear graphs, diagrams and presentations, which streamlined decision-making.

Czero added tremendous value to the Brown project and was a pleasure to work with. We look forward to putting our heads together on future projects.
