A Solar Hydrogen Car

HintLightbulb.png Hint: Hint: Collaborative design of products that matter. Here we design and build and enterprise an open source, solar hydrogen car. Build happening on April 22, 2022, with team organization for start of project Sep. 2021.


  • Collaborative design: all universities collaborate, not compete
  • Hydrogen car is broken into many modules - each is developed open source from engine to body to controller
  • Hundreds of teams collaborate, and start an OSE Extreme U branch. About a dozen branches collaborate on each module.
  • Modular breakdown allows for prototyping with modest budgets
  • Production machines to build parts are open-sourced as well
  • Annual Extreme Build at OSE headquarters brings build together for unprecedented collaboration
  • We reinvent collaboration and reinvent the economic process

Financial Impossible

  • Chapters - incorporate as a student group, $500 event fee for April 22, 2022.
  • 2000 chapters first year, $1M. 3 full time staff - $300k, facility upgrade at FEF - 10,000 sf open center courtyard event hall, and
  • 3 full time staff organizers
  • Invitation out to wide breadth of participants by December. Recruiting Jan - May to 2000 OSE University Chapters.

Open Source Solar Car

We are gathering collaborators for a Solar Electric Vehicle Challenge.

Positioning: all solar, solar hydrogen, human power, hybrid generator, and battery buffer. All solar is limited, solar hydrogen is not limited.


  1. Lightweight electric vehicle running on compressed hydrogen combustion - a hybrid with hydrogen Power Cube
  2. Involves development of open source hydrogen engine
  3. $100k award, 1 year from launch. 2 year project.
  4. Solar hydrogen production - stationary plant, phase 2. 2 year project
  5. Onboard solar hydrogen generation - phase 3. 2 year project.
  6. Proof of concept design - not an optimized design - initially
  7. Focus on Design for Manufacturing - ease of fabrication in commmunity-based microfactories that is more efficient than mass production and allows for circular, open source economies

Copy & R&D

  1. Show that hydrogen internal combustion (IC) cars exist
  2. Show the advantages of hydrogen IC cars over regular cars
  3. Show advantages of hydgrogen over batterries
  4. Address advantages of hydrogen over gasoline/oil economy - decentralized, solar production
  5. Address the disadvantages of hydrogen IC vs fuel cells
    1. Address zero pollution by onboard oxygen
    2. Address efficiency by distributed production - if you count full cycle stewardship, distributed hydrogen makes sense compared to oil wars
  6. Address safety of hydrogen vs gasoline

First Prototype - 3D Printed Hydrogen Car

  1. Open source IC engine with atmospheric oxygen
  2. Hydrogen storage container
  3. Safety system - oxygen detector
  4. Open source electric generator
  5. Open source electric motor
  6. 3D printed car - carbon fiber filament
  7. Collaborative project - all groups collaborate
  8. $15k budget for each team - find corporate sponsors, defined as future of mobility
  9. All components are open source - fabricated, machined, open source CNC screw machine, rubber printed, etc
  10. Project includes developing production tools for fabrication
  11. Designed for distributed production.

Potential Advisors



  1. What if you fail? We are open to fail quickly, to correct, and then to succeed. We will continue on an annual basis, until we get there. So it's a question of when. In the process, we'll be developing several enabling open source production technologies - and generate tremendous awareness about open collaboration. For us, it's a win-win situation for everyone involved, as we accelerate progress to a renewable energy and sustainable technologyfuture. Our vision is collaborative design as a way to develop products - as opposed to patents and secrecy - so we can reach a transparent and inclusive economy of abundance. If we can move the dial at least somewhat in open collaborative development, then we will have succeeded.
