Would you like to collaborate in an unprecedented scale event - to design and build the world's first, fully open source, practical, solar hydrogen car - produced with 100% open source production machines? Impossible. Yes, unless we collaborate openly. Join us for a large-scale (goal of 1000 teams) collaborative design effort by forming a Team Open Source Ecology at your university or school. Got technical skills? Got interest in unbridled collaboration as we open source the whole production tool chain for open source mobility? Then join us to develop the technology and to distribute enterprise worldwide. We are starting annual cycles of development - with a final Extreme Build every April 22, starting in 2022. We are organizing the effort from August 2020 to June 2021, and beginning development in September 2021. The Extreme U is a way to involve Universities and students for long-term development that continues to build on the previous year's work.
