that's just a consequence of relaying complex thoughts simply and actually thinking what he says so there are no misunderstandings. I really like that he does that.
great talk but I can't believe no one said anything about the grasshopper rocket! that video from mid december where the rocket hovered about 10 stories in the air for 30 seconds was stunning!!
"Solar City and Tesla will make drilling, fracking and the truck loads of sand, water delivered to these facilities obsolete." Solar City panel installations reduce your bill, but they do not remove it. There are some very good reasons why they can't do more (having mostly to do with the fact that long-term energy storage is insanely expensive). Tesla cars also only lower the CO2 emissions per mile driven, but they don't remove them entirely, though here the relation is a bit more complex.
Guys. It's 2013. Your video looks like 1958. You have all this scientific and intellectual firepower in the room, the subject matter is the very edge of the tech frontier, there is NO excuse for your online audience being made to look at the tops of bald heads, inaudible i.e. un-miked questions and posting this interview to RU-vid looks like an afterthought; you really have to think hard about this. As always, however, it's great to hear Elon's vision.
i think thats because posting this video to youtube IS an afterthought. funny how people can still complain when you get great content like this for free.
My simple friend, try to understand that there are more star systems in the visible universe than there are grains of sand on all the beaches of the world. Pick up a handful and start counting and then look out on the beach. Each grain is a solar system like ours.
Interesting, the 50% solar power conversion remark - but there had to be more to space solar power than that. Plenty of space engineers who can do that maths. There have to be other advantages. Here are a few: * available year round 24/7 is not just an increase of power. It's a matter of having the power when you want it. With Earth based solar power, then you have plenty of power in the daytime but you need to store that power at night, so it's not just how much power, but when, especially when using large quantities of power. * No clouds, not seasonal dependent. Okay if you are in sunny equatorial region, but e.g. here in the UK then we get most of our solar power in summer, so it is not just daytime, but daytime in summer. So your panel, if you want it to work year round has to be large enough for winter, and produce too much power in summer (unless you can store the energy from summer for winter). Fine if your solar power is in a minority but not so good if it is the main source of power for everyone * In space, it might be easy to build a swarm of thin film mirrors to focus sunlight onto the panels - where the mirrors cost far less than solar panels. And those would be mirrors that we can't use on the ground (too flimsy) so may have cost advantages over similar mirror arrangements on the ground * The space mirror could also be used to beam energy potentially anywhere on the Earth, e.g. for disaster relief. Here is an example of a design that uses a swarm of thin film mirrors to concentrate the sunlight on a much smaller region for the solar cells. motherboard.vice.com/blog/this-satellite-could-be-beaming-solar-power-down-from-space-by-2025 You could address those differences of course, e.g. if we have low cost ways of storing large amounts of power from day to night, it won't matter any more that sunlight is only available in the daytime, and the power used most in the evening. If you have easy ways to transmit power from the equatorial regions to the higher lattitudes, or ways of storing power from summer for the winter, then it won't matter that it varies seasonally and depending on cloud cover in the higher lattitudes. And we can use mirrors on the ground, already do, and though they have to be more substantial, don't have the transport costs into space. And as for beaming power world wide, you could have a space based relay station to relay power beamed up to it from the ground and back down to Earth. Just - seems it's not a "slam dunk case" against space based solar power. And maybe the future has a place for space based power - not instead of ground based solar, I don't think anyone is suggesting we stop using it on the ground :). But as well as it.
Mars and Space Colonization First of al,l what you need to consider about the remark Elon is making towards SSP is that he is not just an engineer, but also a business man. He is not saying it's impossible to implement it with a certain degree of success, but rather that there's no economically viable way to do it, there's no financial case to it, in other words, you cannot build a business around SSP and not even remotely compete with Earth-based solar power which obviously requires far less capital investment and lower installation costs, at least as long as we don't have a cheap way of sending stuff to space...
JC Karbin Yes, but these other studies also look at the finances, the problem is he isn't comparing like for like. Mankins aims to get down to 10 cents per kilowatt hour. Using his idea of a swarm of thin film mirrors concentrating the power on solar panels. That could easily be enough of a cost saving over the heavy mirrors we have to build on Earth to offset cost of launch especially since they can also be very light and don't have to be optically perfect. Elon Musk is good at out of the box thinking, so why try to use basic arguments like this to rule out any possibility of "out of the box thinking" in a field he is not actively working on himself? The energy is then beamed back to a large 10 km diameter array on the Earth that converts low frequency radiation to energy with 80 to 90 percent efficiency. Others could probably have used similar arguments to prove that what SpaceX does is impossible, based on over simplifying the problems they have to solve and the range of available ways of dealing with them. Linking to the idea again - just one of many proposals. motherboard.vice.com/blog/this-satellite-could-be-beaming-solar-power-down-from-space-by-2025
I stare being drug into the poverty of corruption of social societal behavior with refusing psychological medicines, every life near claiming he, Elon Musk, a pychopath struck at an expensive dog named MAX and feeling like it is applying to a job in that this is a way for to figure the real world out, I am in maximum dynamic pressure to basically fundamentally survive in life. Please help to making the boss Elon Musk positioned to save my life because I do have the exceptional abilities he wants to need understanding the hard work needed for the position.
No I'm not jumping to conclusions. I am simply not totally ignorant of the situation like you are. I have examined oceans of evidence and there is plenty to absolutely certain many times over. You just can't handle it.
and you what in this world have you contributed.fluffy humans only focused on speach style and not whats being said.go back to watching the kardashians
