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.
