and we are caltech nerds. we have a reputation. we are featured a certain way on sit comes, "the big bang theory" tv show. >> exactly. i'll show you some of my favourite people doing incredible science. the m.e.r.s. is mcarthur -- first person is mcarthur prize winner, taking an approach to energy, global conservation. >> climate change is not a far-off problem in the future. it's happening now, causing hardship now. climate change is real. we have to act now. >> the debate about whether climate change existed at all is falling to the background. i think people accept it's a reality. it's here. now it's a question of what do we do to combat it. >> on the front lines of combatting climate change is caltech aeronaughtic professor dr john deberiy. he's taking cues from animal. >> the name of the game is how to take energy and consume it. whether it's fish in the ocean, a flock of birds or a plant in a field, they have come across ways to generate energy and consume it. our goal is to use physics to extract how they do it and provide i

or caltech. and i saw that personally when i was trying to get engineering help for my work on "unsafe at any speed." but i never exaggerated their power because i had a very, very realistic view of the power of people. and i realize that corporations, for all their power, they don't have a single vote, and that what members of congress wanted were votes. and so people became alert and they began to realize that it wasn't always the nut behind the wheel in crashes and injuries on the highway, that the engineering systems of highways and vehicles were very critical in minimizing crashes and, if they occurred, minimizing their injuries, such as a seatbelt, then the public interest would prevail. now, that served me pretty well because i had my feet on the ground and i knew i had a lot of work to do. i had to get the technical community behind what we were doing, i had to get it out to the media, i had to have contacts with senators and representatives who remembered where they came from and had a p
