Sea fans are among the most beautiful sights seen by divers. Gorgonian sea fans are Cnidarians that build colonies in branching formations that usually are fan-shaped, thus the common name.
botanist or not you learn about photo synthesis, computer science is just as foundational. reporter: so far code.org has partnered with 120 of the largers school districts to add computer science to the curriculum. results, 20% of all american students are learning the basics of writing computer programs with code.org. and policies and learning requirements have been changed in over 20 states so far. code.org gets the students engaged with simple lessons and by involving celebrities, world leaders and athletes like brown for added inspiration. kyla cash, a fifth grader at twin rivers, taught the steeler the basics. so get this piece and connect it to right here. now hit run. i think my hands are better than my feet with this. reporter: for brown the passion the students have for the class strikes a particular chord. you grew up in a tough part of miami. could you see this being beneficial in an area like that? absolutely. you know, that s all it takes is a program that keeps
prove that there s a new way to communicate to get it done. it s called the delancy underground. it is an ambitious project to convert an old trolly terminal under the streets into an underground park. take a look at their pitch. that s why we invented this new technology wp we call it a remote sky light. concentrates natural sub light at the surface, redistributes it and supports enough life for photo synthesis to grow trees, plants, grass, et cetera. what? they can get the sun from above the ground to below the ground? the idea now closer to reality than ever thanks to the fund-raising website kick starter where innovators like these characters can solicit backers to fund their ideas. some 3300 folks have pledged a total of $150 grand, smashing the fund-raising total after hundred that they set out for, proving that not only the power of social network but proving
here. you spent time with this start-up company. you think this stuff is going to work? alex, i have to tell you, i do believe it is very legitimate. we went really to the front lines of this great effort to harness the sun s nurj in the form of algae. it uses photo synthesis to create sugar energies. in this case it s creating oil which actually can go right into the engine of any vehicle. basically previous to what this company has done this company in san francisco, previously the big problem in trying to manufacture this oil was that they would have to grow the algae on these large ponds out in the open environment. they would need to harness the sun s energy to do this and that put in a lot of unknowns. now they can actually grow this algae in a controlled
