For a muxh more interesting and detailed talk on how it will all work, see Flon Musks talk on how we can achieve this and much much more http://videosift.com/video/Elon-Musk-Making-Humans-a-Multiplanetary-Species

It's not IN a vacuum. the pressure is just very low, like a high-altitude jet airliner. The skis the pod runs on aren't even electromagnetic, they use micro jets of compressed air, like an air-hockey table.

As for Thunderfoot, I get he likes debunking things like those retarded snake-oil "smart pavement" people. However, saying Musk is one of them is ignoring what Elon's already accomplished. I can GUARANTEE Elon Musk has dumped more money than Thunderfoot will make in his lifetime in engineers and pure scientists just to see if it was FEASIBLE, let alone possible.

Will watch this later, but first thoughts: Elon Musk is waaay fucking smarter than thunder fool

Yeah, the battery pack would catch fire if exposed to water, they must have to seal it pretty well.

And yeah, as already mentioned the passenger compartment has a "bioweapon defence mode", presumably because Elon Musk is actually a real life Bond villain and he wants his customers to be safe from whatever doomsday scenario he has planned.

Your video, Elon Musk Explains Why We're Probably Living In A Video Game, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

This says quite a lot about Elon Musk, I feel.

I'd counter his argument by saying its only been 40 years since pong, too short a time to be extrapolating too far into the future. I believe we are approaching a very real physical limit to transistor size, so I don't think its necessarily a given that in another 40 years we will have moved on the same distance. Basically for all we know this could be a momentary blip for a century or so.

but yeah, if you agree that we will continue to create increasingly sophisticated and powerful computers, and that humans continue to be for a little while, then ok, I think it is feasible that we could create a virtual world, which would make me quite terrified that our reality might suddenly BSOD.

A bit of background on his childhood.

I don't know about the revenge part, I'd guess his fame, wealth and attempting to do good by humanity is his revenge.

While the Blue Origin vertical landing is difficult and an accomplishment in its own right comparing it to Spacex is a little unbalanced:

http://www.theverge.com/2015/11/24/9793220/blue-origin-vs-spacex-rocket-landing-jeff-bezos-elon-musk

Twice the speed, twice the height, more burns, a more complex flight path and a much larger, thinner vehicle to name a few differences.

You may want to watch this video on what Spacex has planned for the remaining stages of its stack:

https://www.youtube.com/watch?v=sSF81yjVbJE

To be fair that stack has the Dragon capsule on top and not a satellite delivery bus but the goal to return multi stages is part of the Spacex vision.

"If" Spacex can get the "heavy" version of their vehicle up and running with stage return they will be a force unequalled in launch across the entire industry. That is if they can turn around their stages without compromise to structural integrity.

From an article on ArsTechnica:

SpaceX's founder, Elon Musk, has said it costs the company about $60 million to build a Falcon 9 rocket. The propellant itself only costs $200,000. Thus there is the potential to slash the costs of spaceflight by 10, or even 100 times.

In case nobody caught it, this is not the first time a booster stage returns from space to land on its own power, not the first commercial launch booster landing nor even the first time it happened this year. Blue Origin's New Shepherd recently did just that. This lead to a bit of a war of words on twitter which quickly devolved to a "my rocket is bigger than yours" bragging competition. It's rather humorous therefore to hear this band of professional aerospace PR agents say that this is "history by being the first to fly back and land the first stage of our rocket to land" (@1:20).

Nonetheless an impressive mission and I congratulate their whole team for the accomplishment.

Elon Musk is one of those people where I hope their good intentions never lead them to become evil.

I'll say one thing, Elon Musk didn't make his Billions (pinky to cheek) due to his masterful oratory...
