TEDxSanJoseCA - Jonathan Trent, PhD - Can We Cultivate Energy?
De: TEDxTalks | Criado em: 17/04/2011
NASA Nanotechnology Scientist
To provide practical answers to critical questions regarding sustainable energy, Jonathan Trent initiated a project called "Global Research into Energy and the Environment at NASA (GREEN)." This project, supported by Google, led him to investigate biofuels that do not compete with agriculture. With a Ph.D. in Biological Oceanography from Scripps Institution of Oceanography, Jonathan turned his attention to the oceans as the energy frontier for biofuels and he developed a system called "OMEGA" (Offshore Membrane Enclosures for Growing Algae). OMEGA emerged from his knowledge of the ocean, his years of training in microbiology in prestigious labs in Germany, Denmark, and France, and his knowledge of engineering from his research at Argonne National Lab in Chicago and, for the last 12 years, at NASA Ames Research Center in Mountain View. The OMEGA project is supported by the California Energy Commission and NASA Aeronautics Research Mission Directorate.
TEDxSanJoseCA - Jeff Greason - Rocket Scientist: Making Space Pay and Having Fun Doing It
Jeff Greason has devoted his life's work to creating and managing innovative technical project teams at XCOR Aerospace, Rotary Rocket Company (RRC), and Intel Corporation. Time magazine named Jeff as one of their "Inventors of the Year" for his team's work on the EZ- Rocket in 2002. He is the president and co-founder of XCOR; leading an engineering team that has developed 11 different long life, highly reusable, liquid-fueled rocket engines using nitrous oxide, liquid oxygen, and hydrogen peroxide oxidizers, with kerosene, alcohol, ethane, and other nontoxic propellants. Under Jeff's leadership the company has also developed low cost liquid propellant piston pumps and two generations of piloted reusable rocket aircraft. The EZ-Rocket was flown 26 times, and the X-Racer flew 40 times, without a mishap. Jeff is also the co-inventor of XCOR's Nonburnite technology.

Visitando la Estación Espacial Internacional por Pedro Duque (español) en octubre 2003
La tripulación de la Estación Espacial Internacional habla de la vida a bordo euronews, i talk
Hace 50 años Yuri Gagarin realizó el primer viaje del hombre al espacio. Muchas cosas han cambiado desde entonces allí arriba. Actualmente seis astronautas viven y trabajan en la Estación Espacial Internacional. Los espectadores de Euronews les han hecho varias preguntas sobre su labor.
Sus investigaciones no sólo facilitarán, por ejemplo, el viaje a Marte. También tendrán sus efectos sobre la Tierra. Están estudiando varias enfermedades cardiovasculares, el funcionamiento del cerebro y un tratamiento contra la osteoporosis.
Desde el espacio, cuentan cómo es la vida con gravedad cero y cómo se ve la Tierra desde tan lejos.
