About Cesar


Cesar Minoru Harada 原田 実 (29) is an French-Japanese inventor and entrepreneur.

Cesar invented Protei, a ground-breaking sailing technology.
Cesar is also the general coordinator of the future International Ocean Station and oil spill remediation robotics.

Cesar moved back from New Orleans - where he was studying the oil spill - back to London where he set up the HQ of Protei as a revolutionary sailing technology. Cesar is now teaching Masters in Design & Environment at Goldsmiths University London.

Cesar recently went to Japan to study radioactivity along the eastern coast and hope to come back soon with Protei to measure radioactivity in the Pacific.
Similarly Cesar wants to use Protei to study Plastic debris in the oceans and red tides along the coasts of Mexico.

Former project leader at MIT in Boston USA, Cesar graduated form the Royal College of Arts Design Interactions in London. He worked at the Southampton University Hydrodynamics laboratory on wave energy. Cesar also studied Industrial design at the ENSCI (les Ateliers Paris) and Animation film at ENSAD (Arts Decoratifs de Paris).

His films, performances and installations have been participating many festivals and events in the USA, Japan, France, Greece, Netherlands, Spain, Italy, Russia, Mexico, Germany … He lectured at V2_ Rotterdam, Barbican London, CCCB Barcelona, Goldsmiths University London, Carnegie Mellon Pittsburgh, MIT Media Lab Cambridge, National Institute of Architecture of the Netherlands...

Protei, Open Source, Sailing Drone

Jan. 02, 2009 - Present

Current oil spill skimming technology could only collect 3% of the DeepWater Horizon Oil Spill in the Gulf of Mexico. The health of workers was exposed to cancerous toxicant, the boats were expensive and pollutive to operate, they could not operate in bad weather (hurricane seaon) they could not operate at night or far away. Protei is a technology currently in development that will provide - Unmanned, no human exposed to toxicant. - Green and cheap, sailing upwind, capturing oil downwind. - Self-righting, rugged, can operate in hurricane time. - Semi-autonomous : can swarm continuously and far away. Protei is not the result of academic or scientific research. Protei is a direct response to environmental crises, including the financial and technological inaccessibility of solutions to the general public. It is an exploration of the concept of a flexible-hull sailing boat, and the consequences of this bio-inspired design. As the design of the individual Protei vessel improves, further versions will develop towards the behavior of multiple vessels, making up a swarm of sailing drones. As we progress, the vessel will move towards energetic autonomy, possessing sensing and decision-making skills, and eventually will evolve from a centralized swarm control to a decentralised peer-to-peer autonomy. Protei can eventually be appropriated for other purposes, such as cleaning other chemical pollutants and material waste from the water, as well as collecting samples for ocean research.
But reaching the point to use Protei on all these different applications is quite a stretch. We can make that immediate jump and we’ll need to make incremental technological development. A Protei 1m for Ocean Sensing will be first developed as a toy. A Protei 6m for Ocean Cleaning will be first developed as a manned leisure sailing boat.

Mazda names four TED Fellows “Rebels with a Cause.” Psst: One of their new projects will get funded based on your vote

October 8, 2014

Andrew Bastawrous dreams of a bakery in Nakuru, Kenya, that will not only make delicious treats but raise money for subsidized vision care. Robert Simpson envisions First Responders, a program to make satellite data available to citizen scientists in crisis situations, to guide aid efforts from afar. Cesar Harada wants to create larger prototypes of […]

Unreasonable at sea: Fellows Friday with Cesar Harada, who circumnavigated the globe with Protei

July 6, 2013

In January of 2013, TED Fellow Cesar Harada, inventor of an open-source sailing robot, set sail on a four-month, 14-country round-the-world journey with Unreasonable at Sea, a global innovation accelerator on board a boat. Here, he tells us about how this extraordinary voyage helped crystallize his vision for how his open source sailing robot Protei will […]

6 very promising oil spill cleanup innovations

July 5, 2012

  Two years ago, a chance discussion with a group of Gulf of Mexico fishermen changed the course of Cesar Harada’s life. The TED Senior Fellow had landed his dream job at MIT in Boston, but after hearing first-hand accounts of the conditions in the Gulf following the Deepwater Horizon Oil Spill of 2010, Harada […]
