César Harada: Developing ocean hardware to help clean up the oceans

César Harada – a Franco-Japanese environmentalist and entrepreneur – is the inventor of a revolutionary shape shifting sailing robot, Protei, which has the ability to explore and protect the ocean, collecting ocean waste, with open source technologies.

Protei can collect ocean waste including plastic and can deal with oil spills, collecting up to 2 tonnes of spilled oil in any such occurrence. The hull of the Protei boat is flexible, like the scales of a fish, and is perfectly resistant to waves, enabling it to draw power from waves rather than fighting against them.

César Harada says: “The ocean covers more than 70% of our planet surface. The ocean is the main driver of climate change. It is also where all life comes from. Yet we are destroying it. Plastic pollution. Oil spills. Radioactive leakage. Chemicals. Overfishing. We need to develop solutions to invert the negative effect we have on the ocean.

“[With Protei], the goal is to deploy a fleet of soft, renewable-energy-powered ‘ocean satellites’ to collect ocean data.”

Voluntary contributors from around the world including sailors, researchers, engineers, designers, entrepreneurs, and manufacturers are collaborating with César Harada’s on his Protei project.

The Hong Kong-based inventor, César Harada, who is passionate about the ocean, the arts, open source technology and maker culture calls his technology Open Hardware for the Ocean. Several different users are building and launching their own Protei, collecting data and sharing it with the world.

César Harada adds: “We [Scoutbots] use Open Technology to maximize impact and transparency. As intellectual property is shared, it is in the interest of individuals, non-profits, companies, universities and governments to work together for greater good.”

A builder’s kit to make your own Protei is available through the Scoutbots website, and users are encouraged to share their experiences and help build the databank.

César Harada has also been involved in setting up Hong Kong’s first large maker space, MakerBay, focused on social and environmental impact.

MakerBay provides a space for anyone who is developing an invention or business to use the company’s tools; participate in classes and events; engage with a community of makers; and make use of services including consulting and digital fabrication, in order to help grow their business and develop their invention.
