Elon Musk on the 3 inventions that will change the world

Elon Musk is a 39-year-old engineer and serial entrepreneur. At 28, he co-founded popular e-payment company Paypal. He then went on to start SpaceX, the first private company to launch a rocket into space, and Tesla Motors, which builds electric cars.

I recently talked to Musk about inventions he thinks will change the world. You can check out the transcript below and watch part of our Skype conversation, which encapsulates Musk’s particular brand of big, big thinking (in particular, why we should expand human life into space).

Amar Bakshi: What three inventions do you foresee changing the world in the years ahead?

Elon Musk: One of the most important things that I think that will be invented this century, hopefully by SpaceX, is the first (1) fully reusable orbital rocket. It’s the fundamental invention necessary for humanity to expand to the stars and to become multiplanetary. (Check out the video above to see why Musk thinks expanding to the stars is important for humanity.)

The cost of fuel is only about 0.2% or 0.3% of the cost of the rocket. In fact, the cost to refuel one of our Falcon 9 rockets is about as much as the cost to refuel a Boeing 747 plane.

However, a 747 can be used tens of thousands of times. And that’s the reason a ticket to London doesn’t cost a half a billion dollars (a 747 is about a quarter-billion dollars, and you would need two of them for a round-trip flight if you didn’t have reusable planes). Now you’re paying a few thousand dollars for the ticket because you can reuse the craft.

(2) Rapid, low-cost, perfect DNA sequencing will have a huge effect on humanity. Human DNA has not yet been completely decoded. The most that anyone has gotten is about 91% or 92%, and that has been with a huge numbers of errors. Trying to read our DNA is like trying to understand software code - with only 90% of the code riddled with errors. It’s very difficult in that case to understand and predict what that software code is going to do.

That’s where things are right now in DNA decoding. There’s a company called Halcyon that’s trying to solve that problem. I’m an investor, and I’m on the Board of Halcyon, but I think if Halcyon succeeds in doing perfect DNA sequencing, it will have a huge impact on humanity.

I should mention another important thing. With DNA, you have to be able to tell which genes are turned on or off. Current DNA sequencing cannot do that. The next generation of DNA sequencing needs to be able to do this. If somebody invents this, then we can start to very precisely identify cures for diseases. It will be a really huge advancement for humanity.

We’ll be able to design treatments specifically for individual people and be able to tell beforehand if certain treatments would result in negative side effects for certain individuals.

There are a lot of people that think (3) viable fusion is not possible. But fusion is the “energy forever” solution. You know all energy in the universe originates with fusion. We get our energy from the sun, so that’s indirect reliance on fusion.

Do I think it will be solved this century? It may not be possible – or at least, not on a commercially viable scale. It’s a very, very difficult technical problem, one of the most difficult technical problems that humanity will ever try to solve. But if we solve it, we will have “energy forever.”

Bakshi: Where do you think these innovations are going to happen? Around the world? Or mostly on the west coast of the U.S.?

Musk: Primarily the west coast of the U.S. It is remarkable how much is invented in California. It’s kind of ridiculous. It’s not necessarily the people who were born in California. It’s just that people come here because this is an environment that is really conducive to invention despite the high taxes and all the constraints that one faces.

I was born in Africa. I came to California because it’s really where new technologies can be brought to fruition, and I don’t see a viable competitor. It’s not to say that California is perfect – far from it. But it’s the least imperfect of any place in the world that I know of for bringing new inventions to mass market.

Silicon Valley has evolved a critical mass of engineers and venture capitalists and all the support structure – the law firms, the real estate, all that – that are all actually geared toward being accepting of startups.

You go to some other part of the world, and you know you can't get a lease because your company hasn’t been around long enough; the law firm won't give you legal advice, nobody will give you funding, you can't find the technical talent you need. But in California, all this has arisen organically.

    I agree with Prof. Hawkins and Mr. Musk that for the long term survival of humanity we need to have more then one planet to live on in case of global wide destruction. I also believe that since the timeline is longer then most of us will live we need to start by changing our ways of supporting ourselves and building our shelters. The main idea is to simply buy the needed time for our children and grandchildren to develop the knowledge and technology to do this while limiting the damage we are doing to the surface of the earth and possibly reversing what we have already done.
    Instead of building up, build down, by this I mean burrow into the ground instead of building sky scrapers. The reasons are limitless, geothermal energy, mineral resources, radiation protection, safety from inclement wheather, (other then earth quakes), etc. Granted we will still have a sizable population on the surface, farmers, fishermen, and folks who just don't want to live or work under ground.
    What a great way to learn to live on the moon or in other hostile environments we may find in space. The best reason is freeing the surface of earth to heal itself and letting nature regain its normal state without human intervention. Just think of the great vacations we would be able to take visiting the surface.
    We have built the channel tunnel between England and France and plans were designed for a tunnel between Europe and America along the northern rim of the Atlantic ocean. They have built the facility at Cheyenne mountain and the seed depository to safe guard genetic biodiversity. There are massive subway systems around the globe in the largest cities so it is possible to do this. Though the cost of construction is high it only has to be done once then it should last for ages.
    I am just putting some ideas out there to get people thinking in this direction and to come up with ideas of there own. I also know that I am delving into subjects that are well beyond my pay grade so any and all help will be most welcome. To finish, my thoughts and prayers are with the people of Japan, Libya, New Zealand, and humanity as a whole as we deal with the trials that come our way.

      On Earth we rape and pollute the land for our needs and desires. We have been doing this for centuries. What makes you think that we will be any more responsible elsewhere? It is the nature of the human race to leave a trail of destruction.

    hahaha musk, good one, the reason california is such a place for innovation is the pockets of engineering culture, that have bonded together t ohelp start ups...they are in that mindset...

    the problem is that the government of california is completely fucked up..especialyl the high taxes. seriously, f californias government man, san francisco can ksis my ass.

    if we had the california mentality with texa's low taxes, and combined that with the strict convergent engineering culture of mit (you have all the spectrums), im pretty much certai nwe would get to the singularity by 2015.

    unfortunately, you have a bunch of morons trying like apeshit to cut the nut off industry. f bunch of stupid brats, they don't DESERVE SILICON VALLEY AND ITS TALENT..

    california, the california that created silicon valley, died 20 years ago...the only reason california is still california is that there is a huge helping hand from the high tech industrial complex whose infrastructure was constructed 20 years ago.

    f san francisco, if it wasn't for silicon valley and the creative culture, that city would turn into a bohemian ghetto. sons of ...

        Texas does not have a $28 billion deficit. It has a $28 billion projected budget shortfall. The Texas State Constitution requires a balanced budget, so the State will not have a deficit. The next round of budgeting is going to be painful, but it won't result in a deficit.

        Incidentally, some Texas school districts, particularly those around the Dallas area, rank at the top of the nation.

    If another california sprung up elsewhere i would leave in a heartbeat...sigh...unfortunately I can't...have to deal with that whore...unfortunately there is nothing around the planet YET...quite like the californai created 20 years ago for tech. Its quite frustrating. whores got me by a leash.

        ...don't think she was delusional at all. Objectivism is more coherent than collectivism in all its forms (which basically exudes emotion-based decision making at every decision point, which in turn leads to complete illogic everywhere). There are definitely flaws in Objectivism... however, if somebody's got a more coherent philosophy I'm all ears–I haven't heard one...

        Frankly I'm not sure how you could argue with "I swear—by my life and my love of it—that I will never live for the sake of another man, nor ask another man to live for mine." (Atlas Shrugged)

      Fuel cells are cleaner and more efficient, but they still require a hydrocarbon fuel source such as natural gas to supply the hydrogen. Fuel cells are not a long term solution the way fusion would be, they are a band-aid.

    We need to be able to store electricity cheaply. If we could store electricity wind and solar power start to make a lot more sense. We could nuclear more efficiently. If that stored electricity was in a small enough space we could use it to truly power our cars.

    Actually all of mankind's plans and hopes for the future could be coming to a quick end.
    I feel the human experience was a journey of self-identity and spiritual reality and now that
    God has let us seen ourselves as a species and creation to the point of mass extinction,
    it's just possible his plan and desires for us all along are about to become humanity's reality. In other words he let us develop as a species to get us to the point we are now, and it's his desires and goals for us that are soon going to have the final word, air you breathe with and the planet we all walk on was never our own.

      It's also possible that this cycle has played out for eons. Whatever species comes to dominance on Earth develops to the point where it can wipe itself out, then proceeds to do so. Who knows what species will follow man once we destroy ourselves over petty differences.

    Mr. Elon Musk is right about innovation in California, but the infrastructure has much to be desired such as in Riverside, California 6,000 job losses and the state firing 1,500 teachers due to budget cuts, the sheer arrogance of the "cash up front" and exuberance rediculous high price real estate( in Texas real estate is much cheaper and realistic), California can lead the nation in this. That is a bad "mental block" in tthe state. of Califronia.

    My most needed inventions are (1) more efficient solar electric cells, 15% is ridiculous, expensive, and uneconomical, c'mon chemE's invent!, and (2) in my opinion fusion is still too far away, so in the meantime make our fission products inert or recyclable. again, c'mon chemE's invent. Some of my best friends are chemE's. I'm a mech engr, so we'll make it work after you chemE's produce...

    (1) fully reusable orbital rocket – The cost of the rocket is still only a small part of the cost of the launch. We were promised that the space shuttles would drop the cost of orbital launches, but that didn't really happen, due to the enormous amount of manpower required to prep, monitor, control and refurbish the shuttles each launch. If we needed an army of people dedicated to each 747 flight, the fact that the 747 is reusable would be moot. The way to drop the cost is mostly through increasing the number of flights per year (something the space shuttles never came close to achieving as they were supposed to have done), and also through decreasing the amount of manpower required for each flight. Reusability is one means to that end, but is not the only or the best or sufficient means to that end.

    Mr. Musk's other choices are strong contenders for the title. Another strong choice would be new water purification, sanitation and delivery technology. New database technologies are also going to change our world in radical ways. If we were to find a way to empower the billions of people who currently live with little influence beyond their own small towns, we would also see a seismic shift in world affairs. We still haven't even scratched the surface of what nanotechnology or bioengineering could do.

    Autonomous automobiles should get an honorable mention, as it would significantly improve public safety and fuel efficiency, though I don't expect it to be as big an invention as others mentioned. An autonomous lunar excavator and processor would also be Earth-changing.

    1. Rapid fire, high velocity, kinetic energy guns. Weapon systems with integrated tracking systems that can target ballistic missiles and aircraft at long ranges, even disable orbital vehicles. They would render current nuclear stockpiles, air forces, and navies obsolete. It will be revolutionary to warfare as artillery, the machine gun, and flight were... but in one package.

    2. An organism or chemical process that produces graphene. Carbon nanotubes, the strongest substance that will ever be discovered... ever. Travel in time a million years, it will still be the strongest substance. But can it ever be grown like a tree?

    3. AI... but it will probably kill us or take what it needs to get far away from us, then crash an asteroid into the planet.
