/The story behind Protei, open source sailing drones (Tomiki)
"During his involvement with the cleanup effort of a major oil spill, Cesar Harada noticed the gap between the complicated, expensive technology developed in laboratories and the technology actually in demand.
Dedicating himself to developing technology that is cheap, easily implemented, easy to handle and open-source, Harada created a 200 dollar-budget monitoring device with higher resolution than satellites,
and now works with collaborators around the world to develop Protei, an oil spill cleaning robot which sails using the wind and ocean currents.
Based on his hands-on experience, he emphasizes the need to develop technology which enables the co-existence of nature and human, and calls for the redefinition of technology.

About TEDx, x = independently organized event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. (Subject to certain rules and regulations.)
TED is a nonprofit organization devoted to Ideas Worth Spreading. Started as a four-day conference in California 26 years ago, TED has grown to support those world-changing ideas with multiple initiatives. At TED, the world's leading thinkers and doers are asked to give the talk of their lives in 18 minutes. Talks are then made available, free, at TED.com. TED speakers have included Bill Gates, Jane Goodall, Elizabeth Gilbert, Sir Richard Branson, Benoit Mandelbrot, Philippe Starck, Ngozi Okonjo-Iweala, Isabel Allende and former UK Prime Minister Gordon Brown. Two major TED events are held each year: The TED Conference takes place every spring in Long Beach, California (along with a parallel conference, TEDActive, in Palm Springs), and TEDGlobal is held each summer in Edinburgh, Scotland.
TED's media initiatives include TED.com, where new TEDTalks are posted daily; the new TED Conversations, enabling broad conversations among TED fans; and the Open Translation Project, which provides subtitles and interactive transcripts as well as the ability for any TEDTalk to be translated by volunteers worldwide.
TED has established the annual TED Prize, where exceptional individuals with a wish to change the world are given the opportunity to put their wishes into action; TEDx, which offers individuals or groups a way to host local, self-organized events around the world; and the TED Fellows program, helping world-changing innovators from around the globe to become part of the TED community and, with its help, amplify the impact of their remarkable projects and activities.
