You can breath the air, hunt/gather food, drink readily available water, and easily fashion a shelter in the Americas. None of the this can be done on mars.
On the bright side, there are no native Martians to contend with.
What is the difference if you are not prepared? Will you fail at it?
I tried to kill myself by jumping off of a building, but I can't even do that right. I ended up doing a double back flip and landing on my feet. On the street next to me were two kittens. One turned to the other and said, "See, that's how it's done."
Musk even said that he might like to go to the International Space Station and to Mars himself, but "I have to make sure if something goes wrong on the flight and I die there's a good succession plan and the mission of the company continues."
We're all going to die. The difference is the legacy you leave behind. For most people, it's their children. Others try to make a lasting impressions in other ways. Dying while colonizing Mars is one of those ways.
How so? It's exploring a new planet! We have many hypothesis on how humans can colonize Mars (if it's possible). This is proving one of those hypothesis.
Furthermore, it advances the human race by making it an interplanetary species. Which is in the title of Musk's presentation. Being an interplanetary species makes humans harder to become extinct, and prevents our progress from being lost during a global crisis.
Yes! I fully expect this to work the same as automotive usage-based insurance devices. The most well known in the US being Progressive Insurance's Snapshot.
But to sustain $20Bn or more investment for 40 - 100 years before you have a viable colony needs more financing than one single internet outfit can provide - there are only so many millionaires who would be willing to walk away from their lives here on Earth. That kind of investment would only come from a nation or a religion.
This topic is covered in detail in the presentation. The key is to make the costs as low as possible. The first few trips may only be millionaires with a desire to travel to Mars (this is illustrated with a Venn diagram). Economy of scale make each successive launch price lower, and more and more people fit in the overlap of the Venn diagram. The ultimate goal is to have the per person launch cost be the same as the average house in the US.
Where is his reality show that will fund everything?
He plans to fund everything by stealing underpants. (Seriously, that's in the presentation)
More realistically, he has a bunch of ideas to finance the project. They include a mixture of public and private funding. He even lists Kickstarter as a possible source of funds.
At the end of the funding discussion he mentions having no use for personal assets aside from funding this project. I take that to mean he plans to sell his stake in Tesla and Solar City if that's what it takes to fund this project.
The F-1 was actually optimised for reliability and not-killing-the-passengers hence its abysmal performance by today's standards.
I believe GP was referring to aerostatic nozzle optimization, which every rocket needs to have. This type of optimization applies only to the nozzle, and not the rest of the rocket engine. (pumps, combustion chamber, etc.) A rocket with a nozzle designed for space will not perform well compared to the same rocket with a nozzle optimized for earth at sea level. This is because Earth's atmosphere plays a role in how the gases expand from the engine.
This phenomenon can be observed particularly well on the SpaceX webcasts. The exhaust gases from the engine are expelled directly behind the engine when the rocket is leaving the launch pad. Just before stage separation though, a significant portion of the exhaust gasses can be seen to the sides of the rocket. This is another of the many reasons multiple stages are used in rocketry.
Other trade offs are made between safety and performance, mainly in the combustion chamber and pumps. Experienced scientists and engineers can do some calculations to factor out nozzle optimization and get a more accurate comparison between different types of rockets.
Imagine if they'd spent the last decade making Gnome better, refining it, finding the annoying details, instead of spinning in circles. It would be the best desktop out there right now.

IANAL, but I think this could already be considered illegal under the current US anti-trust, anti-collusion legislation. I'd like to see some lawsuits filed over it.
I have been a big fan/proponent/promoter/user of Lenovo laptops for years. They're rugged and reliable and does what I need them for - I'm writing this on a T510 running Ubuntu 15.04
The T series might be fine, but the G series are complete and udder garbage. The case simply disintegrated on my wife's. Be warned!
However, despite Apple's claims, no barometer can tell if you are climbing a flight of stairs
You are mistaken, modern barometers are phenomenally good. They've got a noise level below 10 cm. Take for example the LPS25H. I've got no affiliation with STM, but I like their chips and find their accelerometers good quality, reliable and easy to use.
The hurricane depression thing is slow moving, climbing stairs takes only minutes, so it can tell.
I'm sure the hardware accuracy is very good. However, my concern is with environmental noise factors that could trick the hardware. Tropical depressions aren't the only thing that can trick it.
Basically the are only useful if they are combined with some very good algorithms to account for inaccuracies caused by the environment.
But weather is not the only thing that can cause significant differences in barometric pressure. Ever walk into a building and get blasted by a gust of wind? What drove that wind? Buildings often have different barometric pressure inside as a side effect of modern HVAC systems.
Having a barometer built into a phone is more useful than you would think, especially when measuring elevation changes.
I've worked with barometers in embedded devices in the past. They're shitty at measuring all but the largest elevation changes. There are many environmental factors that could trick the device into thinking the elevation has changed. Ever go into a building and hear air rushing past the doors? That's because there is a pressure differential between the inside and outside of the building. Just walking inside could make the phone think it has changed altitude by several hundred feet.
Why on Odin's green earth would a telephone need a barometer? Does it also have a temperature probe, and wind and rain gauges? A telephone should have an earpiece and a mouthpiece and precious little else.
A barometer is typically used as an altimeter. I assume they plan to use it to supplement GPS.
However, despite Apple's claims, no barometer can tell if you are climbing a flight of stairs. This is because there are too many environmental noise factors that could produce the same effect. For example, turning on the vent hood in your kitchen could trick the sensor into thinking you increased your altitude by over 100 feet.
I've worked with barometers in embedded devices in the past. I once had a device in central Ohio think it was above 2500 ft in altitude due to the remaining tropical depression from Hurricane Sandy.

That's quite some spin they put on it. If only the invested as much money in their products as their PR.

Slight spin on an old Steven Wright joke.
I would love to volunteer, but don't want to abandon my kids.
That is why I loved the movie interstellar. It's one of the main conflicts in the film.
You've never fixed a bug on a released product while simultaneously developing the next major release?
Products are like sharks. If they aren't constantly moving forward, they're dead.
You go first.

I watched the presentation. The most impressive part is the fact there is already functional prototype hardware for this thing. Not only is a Raptor engine being tested in Texas. There is also a full size fuel tank. Progress is being made.

There are a number of launchers that burn the same engines from ground to true vacuum.
Trade offs were made. Those nozzles are only performing optimally at one altitude. I didn't say it can't be done, it's just not efficient.
SpaceX will be streaming Elon Musk's presentation live on their website.

No way this will fly in Europe.

There was a built in video chat feature in Firefox! I didn't have to use Skype!? Why is the first I heard of it the day they killed it?

Now we know what happens to all of that data that's routed through /speedtest.

When people proclaim their good qualities so publicly, it's because they want to con you.
Apparently their name refers to the physical integrity of oil pipeline hardware, and not the character of their employees.
