TEDxSanJoseCA - Jeff Greason - Rocket Scientist: Making Space Pay and Having Fun Doing It

He's a Rocket Man!

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.

About TEDx, x=independently organize 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)

Capitalism FTW!!!

[topikamew]

Great and inspirational speech. The capitalism he is pointing out is the freedom to create and innovate products competitively to maximize our potential as humans to be able to get the vast amount of resources/land out there in space.

Think about capitalist vs communist countries. The reason all bad things happen is because of human vanity and deceitfulness, not the idea of how wealth should be earned.

Cool spaceships and a great idea. I would love to fly out into space one day, wouldn't you?

[cleogonzalez614]

This is a "pretty" video. =p

[GveMeLbrtylGveMeIPad]

Inventors are simply brilliant technicians- it's often not really fair or even a good idea to ask them for their views outside their specialty.

There is no western civilization ... only human civilization. our story is theirs and theirs is ours. It will be one species sharing the common identity of the same homeworld that will be leaving Earth for the stars ...

I am at the strange part of Youtube yet again.

@spoddie Again I'll be more than happy to send you the PDF. And the LFTR works! It was up and running for 4yrs before the Cold War necessitated it's shutdown. And here's the nuclear engineer community discussing it's viability. From what I understand, if the political will was present these reactors could be rolled out in 5 yrs time.

@spoddie Having a bad day? I can send you a PDF if you want. Shoot me an email address. In my own words though, well in short, many factors go into a planets ability to retain an atmosphere, e.g. mass, distance from sun, rate of heat loss, geomagnetism etc. Molten metals moving in complex convection currents generate geomagnetism. Thorium, uranium and K-40 enable these convection currents and in addition the radiodecay heat keeps the core hot and the cycle flowing. Earth is Th reactor

[spoddie]

@jaeLAX23 I love hearing from crackpots, especially thorium crackpots. Shall we just back up a truck full of thorium and dump it into Mars' core? Can you explain in your own words how thorium can sustain an atmosphere? Please use scientific principles rather than fancy video effects.

[jaeLAX23]

@spoddie It's rather Mar's has a weak magnetosphere. It doesn't have enough Thorium mass to sustain an atmosphere for longer than 1000 yrs. If however Thorium mass is added it can sustain an atmosphere permanently.

[spoddie]

Fail.

We cannot kick start life as described by Jeff Greason. Mars can never have an atmosphere because it has no magnetosphere - the solar wind strips off any build up of gas.

Does Greason and/or his company have a website?
