It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will. Elon Musk Travel
It is theoretically possible to warp spacetime itself, so you're not actually moving faster than the speed of light, but it's actually space that's moving. Elon Musk Space
The space shuttle was often used as an example of why you shouldn't even attempt to make something reusable. But one failed experiment does not invalidate the greater goal. If that was the case, we'd never have had the light bulb. Elon Musk Space
The value of beauty and inspiration is very much underrated, no question. But I want to be clear: I'm not trying to be anyone's savior. I'm just trying to think about the future and not be sad. Elon Musk Beauty
In order to have your voice be heard in Washington, you have to make some little contribution. Elon Musk Politics
In order for us to have a future that's exciting and inspiring, it has to be one where we're a space-bearing civilization. Elon Musk Future
It's obviously tricky to convert cellulose to a useful biofuel. I think actually the most efficient way to use cellulose is to burn it in a co-generation power plant. That will yield the most energy and that is something you can do today. Elon Musk Power
It's not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it's a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere. Elon Musk Power
The value of beauty and inspiration is very much underrated, no question. But I want to be clear: I'm not trying to be anyone's savior. I'm just trying to think about the future and not be sad. Elon Musk Beauty
Over time I think we will probably see a closer merger of biological intelligence and digital intelligence. Elon Musk Intelligence
I'm reasonably optimistic about the future, especially the future of the United States - for the century, at least. Elon Musk Future
When Henry Ford made cheap, reliable cars people said, 'Nah, what's wrong with a horse?' That was a huge bet he made, and it worked. Elon Musk Car
I think it's very important to have a feedback loop, where you're constantly thinking about what you've done and how you could be doing it better. I think that's the single best piece of advice: constantly think about how you could be doing things better and questioning yourself. Elon Musk Best
I'm interested in things that change the world or that affect the future and wondrous, new technology where you see it, and you're like, 'Wow, how did that even happen? How is that possible?' Elon Musk Future
In the early days of aviation, there was a great deal of experimentation and a high death rate. Elon Musk Death
I'd like to dial it back 5% or 10% and try to have a vacation that's not just e-mail with a view. Elon Musk Work
