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

[@MundaneMuser]

He made very good points in his speech. Very well done.

[@RobertZeck]

wow, i´m impressed. good talk, true statment

[@jegolan]

How can anybody not like this? It's just mind-boggling. It's as if those 'dislike' people are anti-human.

[@MichaelMooring]

Perfect. Thank you for giving this talk Jeff Greason.

[@oak4901]

Well done, Jeff...

[@ryanhatzenbeller1649]

15:35 If you only watch one part of this video. Here is the most important point.

[@carolemiramont1262]

Very inspiring talk. Clear, positive, trailblazing. Congratulations Jeff Greason, and love the humor!

[@jdorritie]

Liberty and innovation hand in hand, spoken as clearly as I've ever heard it. Truly inspiring.

[@truevoice08]

Don't take the blessings of civilization for granted. The world envisioned by Greason is possible as long as people remember the principles of sound economics. I highly recommend Jeffrey Tuckers book "It's a Jetson's World". Free to download online

[@DTHRocket]

Guess who's interning at his company and living the dream! This guy!!

[@khan06180]

DTHRocket are they hiring by chance. FIU Grad Masters: Electrical Engineering Batchlors: Biomedical Engineering Working on certificate in robotics Passionate about space and space travel

[@doodelay]

This man sounds like he had the exact same experience as Elon Musk and went through the exact same thought processes and drew the same conclusions. It's kind of incredible

[@stephenhumble7627]

SpaceX doing very well but XCOR went bankrupt SX almost did as well. XCORE had good ideas but getting from idea to profitability is a difficult path.

[@LTF85199]

wow, what a great speech

[@jangofet555]

that talk he did was amazing

[@christianlibertarian5488]

I loved this talk. He did, and is doing, what I only dreamed about. And I think he is right: it's now or never to develop commercial transport to space.

[@damilarearah]

question is where would we go? & What would we do? the whole point of commerce. Or else you'd never be able to sell the point to the masses only to the 2.5% of the Bell Curve

[@JRLeeman]

I completely agree with his point on NASA. NASA and the ESA's lack of ambition and reliance on the US or European governments for funding is one of the reasons why i'm working toward becoming an aerospace engineer.

[@Adventuredude2]

Outstanding!!

[@differous01]

And the Cannae Drive works, though scientists have yet to understand why. Possibilities are opening up. Maybe a powered version of the Voyager probes will be possible, or some combination of powered and sail driven vehicles...

[@granddad2002]

I've seen lots of ideas about how to do exploration & development in the 'cosmosphere'; everything in natural principles that can be calculated to the 10th decimal place. The big challenge has ironically be getting the financing to do it. But its amazing how the cost have been coming down when you get better at it. The next hurdle will be how to close the loop between Earth & Space? Space stations, lunar sanctuary bases, asteroid & comet industrial sites? I think its time to do big things.

[@ekim1966]

An example of objectivism at its finest. Here is a man of the mind! True innovators like him, and others, will save us from the next dark ages imposed by the troglodytes who believe the earth is 6,000 years old, and that a blastocyst is a person. Men and women like him ask not "who will let me?" but "who will stop me?"

[@cdbob]

This is a fantastic speech

[@nudenut]

Awesomely inspiring! Would love to get him to present this to a Mars Society audience here in NZ!

[@Marcoose81]

Mars is a big job. I personally am convinced that its possible to build comfortable, self sufficient, city sized habitats in space sooner. There are a few likeminded people around, and that may be enough. Space industry, to produce biofuels or scoot around mining asteroids, has potential, considering the scale possible. Any good business needs to be based on a philosophy (like apple or even samsung) & I don't want to get sentimental - but very practical, and do it.

[@Etaukan]

What a great goddamn speaker! Very inspirational stuff.

[@hendrikm.900]

This was an amazing speech , really eye opening , I wonder why this haven't more clicks, It should have more... I go share it now

[@JRLeeman]

@MONDARIZDK If you scale for time - it is. The sierra Nevada and their surrounding area were some of the most inhospitable areas to man on the planet. The same is true of mars (except it isn't on earth - obviously) and hence it is proportionately by time an quality challenge, there are already proposals for terraforming mars which involve deliberate pollution - technology we know we have. All it requires is the competition he discusses driving technology forward and making it cheaper. The same

[@pandaownsyou]

Can anyone who knows more than me tell me if the propellent cost he mentions is the cost to put the weight of a person into space or the weight of a person and the required machinery as well?

[@Kulumuli]

I like this guy.

[@littlebrotha123]

6:34 - BOOM!!

[@petekuhn]

Nice use of Thomas Hobbes!

[@KD0IDB]

Very inspiring and motivating!

[@batmanbegins72]

ted talks are getting more funny each day

[@Marcoose81]

You missed the bit about the "WHY". Watch it again.

[@celebrim1]

Rather than just hitting me with a bunch of unthinking punctuation, it would be nice if you'd think about why I said what I said. What is it about Sagan that might be construed as a departure from science as the basis of engineering or science as the basis of understanding, and instead might be seen as science being employed as a front for or justification for beliefs not held on the basis of reason? What about Carl Sagan ought to seem in retrospect particular to the New Age culture of the time?

[@AlexWearsHatsArt]

@cupmyplums I thought the idea was that it would cost much less than 'huge sums of money' to be a part of these trips. Not to say they wouldn't be rather expensive for the first while, but I think his vision is to have the flights into LEO (I think that's what he was suggesting with the 'lynx' project he is working on') just as routine as a flight aboard an airliner.

[@brainplay8060]

Nano satellites is pretty big business. More would like them but can't afford them. Satellite repair would also be something to consider. If cost to reach it is so low then making them modular and repairable is suddenly conceivable. Garbage collection is another consideration. There are many satellites in low and high orbits plus junk that is floating and a hazard. Have the UN pay for the service. Many countries would be happy to contribute. Plenty of things to do out there.

[@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?

[@whiteshark27]

@tim5208686 What advances? We ARE talking about the age that followed the Black Plague right?

[@outrageousgriot]

There is a lot of truth to what this mam says. Though I may disagree with his skepticism regarding global warming, this is an idea that I haven't thought... Immigration to mars... How fascinating.

[@SonOfTerra92]

I admit that there are distinct lines that can be drawn in between people and nations (from culture to religion) but what i'm saying is that if we are to survive, our loyalties must be given to the entire civilization not just a particular flag, I dont deny history, merely just considering what it will take to move forward try reading Carl Sagan's Cosmos, you will know what I refer to ...

[@snowboomer5004]

what's the name of his company?

[@DanielMOFO]

Competition is an aspect of a social Darwinism. Social Darwinism is quite an inhumane concept. Don't forget that some things could never be established without teamwork e.g. the ISS.

[@caihao816]

give you a good advice, if you want to go to the space in a much more affordable cost. Study about antigravity, either be keshe technology or searl effect

[@NathanDahlin]

Jeff has identified the problem with NASA and how we should go about fixing it in order to continue exploring space. It turns out the answer isn't exactly rocket science! (Wait...or is it?)

[@GScully42]

where do I sign up? Need a network engineer?

[@chandlersupple3553]

So well said.

[@hinowisaybye]

The continuation of our species?

[@ThatAdelaideGuy]

As a 17 year old I assure you. There will be no Dark Age

[@MrDinoSayRawr]

amazing information thank you for sharing it

[@Marcoose81]

Hedonism is not just the pleasure of the moment. Not Epicurean hedonism anyway. Hard work is important to set up a great meal and an intelligent cannot over indulge with pleasure when they consider the ensuing hangover. Without pleasure what is life?

[@DavosJamos]

BURN THE LAND AND BOIL THE SEA YOU CAN'T TAKE THE SKY FROM MEEEEE

[@wesa216]

Very interesting! Civilization can always get better. I'm not sure about the political message however. It's true that NASA has been getting lackluster results lately, but with so little funding how can we be surprised? Not every accomplishment can happen with a purely capitalistic society. We need government projects, like the Apollo missions, to tackle the expensive and difficult challenges that corporations motivated by profit never will.

[@ekim1966]

@IRUKANJI Re: petty bickering... I was speaking of the difference between honest unbiased scientific discovery and the pseudo-science of mysticism. The latter of which has been trying to worm its way into our educational (and legal) system for years. Both statism and mysticism infantilize human beings. If we leave the nest, we should be "adults". And yes, sound economic principles must be founded on free, honest exchange by free people. Also, I'm not really worried about a human shortage.

[@celebrim1]

Ok, let me at least give a hint while you are thinking about it: Why is the Drake Equation not only extraordinarily bad science (so bad that it makes Intelligent Design seem benign by comparison) but in fact utterly destructive to the very notion of what science is? The answer to that question is in my opinion critical to what Sagan was popularizing, and it definately was not science.

[@ToxinMortalis]

@quotoo You really didn't watch the video, did you. All your questions are answered.... if you actually watch the video.

[@Lawiah0]

So this guy leaves on Illusions and Science Babel.

[@Yosemited]

@Matic293 GOOD THING YOU WROTE ALL THAT USING PRODUCTS SPAWNED BY CAPITALISM WHAT YOU DESCRIBED IS IRRESPONSIBLE CAPITALISM

[@adorablekattroll9641]

Building rocket-planes the could go to sub-orbit & beyond? I have got to thank the folks who gave us the microchip; a proven strategy where you produce a computer from starting with ungainly iron & lead filing cabinets with vacuum tubes and telephone trunk lines that needs a power plant to operate and mathematicians with PH.Ds to organize the inputs... now you can by a whole system cheaper than an HD television and have no more training than basic typing with a point and click mouse? This is where you use better materials, lesser complexity of use and the whole thing dovetails down to something everybody can use. What a way to build a world.

[@Marcoose81]

But that's why NASA failed Arnold, lots of great minds but no motivation to succeed, the culture becomes one of protecting your job and not offending anyone (by challenging ideas). Healthy competition is co-operative, not focused on damaging the others efforts but on improving your own. Do you think Usain Bolt wold run as fast as he does if he had no-one to race against? Love alone will not get it done, hard work is what's required.

[@stardolphin2]

And yet there's Venus... Also no magnetosphere, closer to the source of the solar wind, yet more atmosphere than it knows what to do with. It's not *all* about the magnetosphere...

[@stardolphin2]

That denies all the distinct ways humans have lived (and still live), especially prior to rapid travel and communication. If you believe it's all just one, you've not traveled, and/or paid attention in history/social studies class...

[@fuunguus]

This is great and all, but I don't like the focus on colonizing Mars. Mars is a hostile planet, with virtually no atmosphere (1% atmosphere density compared to ours), and it has no protective magnetic field so even tho we manage to terraform Mars, it wouldn't last long. Also, there is little point in colonizing Mars, cause where would we go from there? We would just be stuck in another gravity trap. We need to colonize space, or more specifically, asteroids, now that would fuel human progress!

[@MrBugman2525]

I believe in the movie 2001 a space oddesey

[@stardolphin2]

This just can not be said loud enough, or often enough...

[@tim5208686]

@whiteshark27 Actually no. the so called "Dark Ages" are another term for the Early Middle Ages to the High Middle Ages (roughly the mid 5th century to the 15th century). What followed the so called "Dark Ages"--the Anabaptist Rebellion, the Peasant Revolt, Lutheranism, Calvinism, the police state and the looting of England under Henry VIII and Elizabeth, the massacre of the Irish by the English under Cromwell, The Thirty Year's War, the French Revolution, etc.--was the true dark period.....

[@tim5208686]

@PatriotsRepublic See my reply to Whiteshark27. I am not a "Statist", and "Statism" was not the governing principle of the Middle Ages. Subsidiarity was the prevailing political philosophy of the age.

[@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. /watch?v=WKG6wZtcVVQ

[@AlexWearsHatsArt]

@someuser91 'Toys for the rich'. Hell no. You seemed to overlook a lot of other applications. Pay closer attention to the video.

[@jaeLAX23]

@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. bravenewclimate(dot)com/2011/11/17/ifr-lftr-exchange/

[@donk.johnson7346]

I was born 20 year too soon.

[@fuunguus]

@kittehjam Wut. There is much more space to live on out in the asteroid field, and it only takes twice as long time to go there as it takes to go to Mars. ION thrusters can make that trip only last 2 months or less, that is nothing! If we colonize one of the asteroids that have metal cores or contain 30% iron, we'll have materials in huge quantities to build whatever we want. Mega telescopes, cities, and all the space ships we want. This should be the future of humanity, not Mars!

[@eafindme]

"Let's nuke the Mars", Elon Musk.

[@rwdisland]

No we need to filter the CO2 from Earth and send it to Mars. Cool Earth down and warming Mars up. I have the Idea for it too... [e-mail] 2542452484

[@JDNuvo]

I love Rocket Science Barbie and they call me j lo. Can I go into space?

[@pauldannelachica3742]

👍👍👍

[@jomhdz]

We need to go to mars end colonize it now.

[@caihao816]

Life is better of course for you. You are the rich, not the middle worker. But thinking about the poor in other country.

[@arnolddaman4696]

Capitalism and competition. WTF? Why its not like this guys company and theyr competitors join forces to work togeather to get to a way batter solution than they seperatly would. More minds focused on the same goal and cooperating means better and faster solutions.

[@jaeLAX23]

@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]

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.

[@strapt313]

@Matic293 Stop drinking the Kool-aid kid. All that you think you know is wrong.

[@wilrod140]

Just reading some of these comments makes me wish I was young again and knew it all or maybe go back to college and be a liberal arts major......same difference lol

[@xMswmSwmsWx]

@celebrim1

[@Nutzername36]

because he believes in destroying human potential... it would make sense to him ;)

[@ekim1966]

@emschafe It is you who equate Christianity with troglodytism, not I. Hedonism is not rational self interest, it is acting on the pleasure of the moment. It is not synonymous with Atheism, which is the lack of belief in gods. Hedonism is not an attribute of Atheists, who are mostly very rational. I never insinuated that human beings are nothing more than a pile of cells, but that a group of undifferentiated cells isn't a man any more than an acorn is a fully formed oak. Straw man fallacy.

[@ekim1966]

Hmmm, Ctrl.+ F "abortion". Nope, not found in any of my posts.

[@foxtrotalphaone]

He lost me at "capitalism".

[@outrageousgriot]

Was this a video advocating a mans love for capitalism or the emergence of an entire new industry - capitalist rocket flights... But I'll be honest there is a lot of truth to what ts

[@Btree33]

yeah capitalism took us to the moon too right??? smh capitalism is the reason we havent been back!!!

[@Gorilder]

BS. bad policies and government trying to run their own projects is why we haven't been back.

[@StevenKHarrison]

Capitalism is NOT the answer! Cooperation not competition!

[@hinowisaybye]

such a thing does exist sadly.

[@Nutzername36]

so u think that over 100.000 people starve to dead every single day because of human vanity and deceitfulness?

[@quotoo]

I watched it again. You are still proseytizing a philosophy, not a business. even if the cost per pound to orbit were a hundred times less than shuttle, what are you going to transport there and back OUTSIDE of communication satellitess? Rich people who want a thrill? Surely you're not going to haul out the solar power satellite? That old chesnut may see it's day, but not for a long, long time. If you want to get sentimental about space, go to the JPL website and see those images from Mars

[@hinowisaybye]

Ah, you didn't use the word abortion in any of your posts, my bad, i see the errors of my ways, and resign.

[@plavix221]

Yeah competition is great! Look what the cold war has brought to fruition. XD God bless America!

[@hinowisaybye]

How is Globalism a bad thing?

[@DanielMOFO]

and corruption

[@Nutzername36]

xD wired world view man... if u think leaders exists because they should feed people u should do an reality check. watch davins nightmare e.g. ;) i´m with u in the last part of u comment, but i think this matches every time. understand this and it will be obvious that leaders don´t should feed people, etc. it´s simply not their job. 100.000 = 100000 100,000 = 100

[@hinowisaybye]

wait, are you trying to bring abortion into the comments on a video about the potential of man, a little bass ackwards isn't it?

[@Btree33]

all these capitalists will do is take us into orbit..whoopdyyyy do..they cant go to the moon or beyond ..you need a govt and a nasa for that

[@Gorilder]

Google lunar X prize, Space X, Boeing, Mars One, etc. they are already going.

[@christianlibertarian5488]

+Vasilis Roumeliotis You clearly missed his point. He thought that too, until the Challenger disaster. It was then he realized NASA and government was never going to take us back to the moon, and was never going to bring the cost of space transport down.

[@Nutzername36]

because the BS he talk about capitalism?! :O

[@aepceo1]

Partial capitalism is fine but hard core capitalism does very little for the good of the whole.

[@christianlibertarian5488]

+Justin Dixon I think you will find very little empirical data to support your statement, and a whole lot of data to show that capitalism does more good for humanity than any government ever.

[@easyittv]

I don't know why there is a negativity in Capitalism, but I'm sure everything you have now is because of capitalism. The food you eat, the dress you wear and the house that you are in.
