About this project

We are developing Protei : a low-cost open-source oil collecting robot that autonomously sails upwind, intercepting oil sheens going downwind. Protei combines conventional technologies in an innovative design that we can implement in the short term to address timely environmental crisis such as the BP Oil Spill, cleaning the ocean gyre garbage patches or performing ocean research. We need your help to build our next prototype of Protei - the first articulated sailing boat that can tack upwind pulling a long heavy payload and initiating a revolutionary family in ocean robotics. 

A situation we must change 

Current Oil spill skimming technology was able to collect only 3% of the BP Deepwater Horizon Oil Spill. The health of remediation workers was compromised by exposure to cancerous toxic chemicals, skimming boats themselves contributed to pollution and were expensive to power, operations were constrained by daily weather conditions and were limited by proximity to the coast. In contrast, Protei aims to be : unmanned, unrestrained by human biological needs; green and affordable; self-righting and therefore operable even in hurricane conditions; semi-autonomous, so that far offshore, many Protei would be able to intelligently and continuously swarm.

Observations and ideas from testing 

 Spilled oil moves downwind from its source following surface currents. Traditional oil skimmers pull oil-absorbent booms and trace random linear paths in a sea of oil. But a better way to capture this oil is to sail upwind, intercepting the oil sheens traveling downwind. Protei harnesses the wind in order to power an unmanned sailing drone, pulling a long oil-absorbent ‘tail’ upwind. A fleet of many Protei will work automatically as a swarm, or be remotely controlled by coastal residents and on-line gamers.

When you pull a long heavy object behind a traditional sailboat, the center of gravity is altered such that in order to preserve navigability it becomes necessary to redesign the relationship of hull, keel, and rudder. The solution we found is to design an entirely articulated sailing boat that curves when it tacks upwind. Building and testing consecutive prototypes with multiple sails, we soon realized that Protei's hull bending would expose both sides of the vessel to the wind when tacking upwind, continuously catching wind with the different sails, increasing power and control - and creating a totally new way of sailing! We also found out that an inflatable body would make Protei featherweight for a very large sail surface : an excellent power ratio. Inflatable means also cheaper and collision-safe. Version after version, we keep improving the design and discovering new properties. 


 - Protei_001 : front steering, Remote Controlled. 

 - Protei_002 : articulated sailboat, Remote Controlled. 

 - Protei_003 : articulated inflatable sailboat, lightweight and larger sail surface, good power ratio. - Protei_004 : electric, swarm for display, art. 

 - Protei_005 : electronic, on-board sensors and micro-chip control, wireless real-time communication and monitored with webcam to analyze trajectory. 

What the money is for   

- Protei_006 : We need money to build our next prototype at full scale to measure the performances : * how much oil can be absorbed. * how much floating plastic debris we can collect from the ocean garbage patches. * how much weight of scientific payload we can transport for ocean studies and exploration. This next prototype will be packed with electronics and sensors: micro-controllers, GPS, long range wireless communication, solar panel, wind turbine, accelerometers, anemometer, pressure gauges, batteries, servo/step motors, winches etc. Many of us will gather 3 months this summer in Rotterdam (Netherlands) to build our next prototype and publish the full online documentation so others can build their own versions too. 


Oil spills are happening all the time across the world. In many of these locations, access to effective yet inexpensive remediation technology is lacking. Thus, Protei is Open Hardware so anyone can use, modify, and distribute Protei. Currently Protei is being developed as a team effort by Open_Sailing in the UK and France, V2_ in the Netherlands, randomwalks in South Korea, Amorphica in the US and Mexico and contributors from all around the world. If you cannot back us, you can work with us :)

Protei is the plural for Proteus, Greek sea-god and son of Poseidon. Proteus was known for his mutability, his capability of assuming many forms. The word protean evokes flexibility, versatility and adaptability. The machine we are developing now is Protei for collecting spilled oil at sea, but being an open source project, other versions may be designed in the future for other purposes : to harvest the Great Pacific Garbage Patch, to capture heavy metal pollutants in coastal areas, extract toxic contaminants from urban waterways, perform oceanographic research, monitor marine life etc.

We hope that developing Protei Open Hardware will contribute to ocean studies and pollution remediation. Help us build our next prototype. Thank you!

Special thanks to


  • Thanks to your support we were able to build a 3 meters long sailing Protei in Rotterdam NL this summer 2011. Since we have been working hard making more prototypes to deliver you a machine that is highly performing, tested and well documented. We are sorry to make you wait to deliver you the reward but we do not want to give you the documentation of a machine that would not be performing well. This summer 2012, 2 of us will be working intensively to transition from prototype stage to product and we really hope to deliver your 1m RC Protei, documentations and other rewards for Christmas 2012. We are doing our very best, thank you again for your support.

  • Yes, Open_Sailing has changed name and it is now called Open-H2O. As we are growing we are setting ourselves up as 2 separate entities : Open-H2O is to become a non-profit organisation to "Promote and Develop Open Technologies to Understand and Protect Water and the Oceans." While Protei is to be turned into a Green Tech Start-up, a B-corp.
    This diagram explains it quite well I think :

    Open_Sailing website is very out od date and will soon be replaces by a brand new Open-H2O, we're working on it. It will be a great community website to
    1. Co-develop technologies. A little bit like
    2. License your work under "Open Hardware H2O", our flavour of Open Hardware license for water and maritime applications. As simple to use as
    3. A real-time environmental data-sharing / mapping platform, inspired by former now…

    More soon! Stay tuned.
