“The world today has 6.8 billion people. That’s headed up to about 9 billion. Now if we do a really great job on new vaccines, health care, reproductive health services, we lower that by perhaps 10 or 15 percent…”
Aside from his theological beliefs about man-made global warming and carbon dioxide, Microsoft Founder Bill Gates made this statement during the TED2010 Conference – weeks after he donated $10 billion to develop and deliver vaccines to children. Although there is no evidence that parents think of vaccinations when they marry and have babies, Gates and his disciples believe that vaccines (not clean water and good nutrition) will reduce child mortality in developing countries, which will motivate parents to reduce their number of offspring.
When Saddam Hussein threatened to use biological weapons of mass destruction (WMDs), Americans invaded his country and changed the regime. But when a software engineer spends $10 billion to deliver vaccines to kill at least 680 million people reduce developing-world populations by 10-15 percent, he’s celebrated as an intellectual.
Gates’ friendship with the industry is troubling. Since 2004, the pharmaceutical industry has paid $8 billion to settle thousands of criminal and civil complaints related to the illegal marketing of drugs that killed or injured a million Americans every year. If tracked like real diseases, adverse drug reactions (ADRs) would rank between the fourth and sixth leading cause of death in the United States – far below the diseases that Gates ostensibly wants to prevent.
Unlike ADRs, diseases like measles, mumps and rubella (MMR) became statistically irrelevant by 1955 – nearly two decades before the drug industry began to push vaccines for MMR during the 1970s. As Luc Montagnier MD admits in this video, the NIH, CDC and drug companies push drugs and vaccines because they cannot profit from the distribution of clean water and good nutrition.
By 1976, the so-called swine flu epidemic became the first of many CDC-caused scandals that unnecessarily killed or injured millions of Americans since 1975.
If infectious disease became statistically irrelevant by 1955, why did the CDC and drug companies start to market vaccines for these disease in the US during the 1970s? Why are Americans children who face no risk of death from these diseases compelled to use drugs and vaccines that are considerably more dangerous?
“(I)t’s against the law to do many things, but the law winks when a reputable man wants to do a scientific experiment… Unless the law winks occasionally, you have no progress in medicine.”
Gate’s unedited comments are posted here.
I’m going to talk today about energy and climate. And that might seem a bit surprising because my full-time work at the foundation is mostly about vaccines and seeds, about the things that we need to invent and deliver to help the poorest two billion live better lives. But energy and climate are extremely important to these people, in fact, more important than to anyone else on the planet. The climate getting worse, means that many years their crops won’t grow. There will be too much rain, not enough rain. Things will change in ways that their fragile environment simply can’t support. And that leads to starvation. It leads to uncertainty. It leads to unrest. So, the climate changes will be terrible for them.
Also, the price of energy is very important to them. In fact, if you could pick just one thing to lower the price of, to reduce poverty, by far, you would pick energy. Now, the price of energy has come down over time. Really, advanced civilization is based on advances in energy. The coal revolution fueled the industrial revolution, and, even in the 1900’s we’ve seen a very rapid decline in the price of electricity, and that’s why we have refrigerators, air-conditioning, we can make modern materials and do so many things. And so, we’re in a wonderful situation with electricity in the rich world. But, as we make it cheaper — and let’s go for making it twice as cheap — we need to meet a new constraint, and that constraint has to do with CO2.
CO2 is warming the planet, and the equation on CO2 is actually a very straightforward one. If you sum up the CO2 that gets emitted, that leads to a temperature increase, and that temperature increase leads to some very negative effects. The effects on the weather and, perhaps worse, the indirect effects, in that the natural ecosystems can’t adjust to these rapid changes, and so you get ecosystem collapses.
Now, the exact amount of how you map from a certain increase of CO2 to what temperature will be and where the positive feedbacks are, there’s some uncertainty there, but not very much. And there’s certainly uncertainty about how bad those effects will be, but they will be extremely bad. I asked the top scientists on this several times, do we really have to get down to near zero? Can’t we just cut it in half or a quarter? And the answer is that, until we get near to zero, the temperature will continue to rise. And so that’s a big challenge. It’s very different than saying we’re a 12 ft high truck trying to get under a 10 ft bridge, and we can just sort of squeeze under. This is something that has to get to zero.
Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it’s about 20 tons. For people in poor countries, it’s less than one ton. It’s an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero. It’s been constantly going up. It’s only various economic changes that have even flattened it at all, so we have to go from rapidly rising to falling, and falling all the way to zero.
This equation has four factors. A little bit of multiplication. So, you’ve got a thing on the left, CO2, that you want to get to zero, and that’s going to be based on the number of people, the services each person’s using on average, the energy on average for each service, and the CO2 being put out per unit of energy. So, let’s look at each one of these and see how we can get this down to zero. Probably, one of these numbers is going to have to get pretty near to zero. Now that’s back from high school algebra, but let’s take a look.
First we’ve got population. Now, the world today has 6.8 billion people. That’s headed up to about nine billion. Now, if we do a really great job on new vaccines, health care, reproductive health services, we could lower that by, perhaps, 10 or 15 percent, but there we see an increase of about 1.3.
The second factor is the services we use. This encompasses everything, the food we eat, clothing, TV, heating. These are very good things, and getting rid of poverty means providing these services to almost everyone on the planet. And it’s a great thing for this number to go up. In the rich world, perhaps the top one billion, we probably could cut back and use less, but every year, this number, on average, is going to go up, and so, over all, that will more than double the services delivered per person. Here we have a very basic service. Do you have lighting in your house to be able to read your homework, and, in fact, these kids don’t, so they’re going out and reading their school work under the street lamps.
Now, efficiency, E, the energy for each service, here, finally we have some good news. We have something that’s not going up. Through various inventions and new ways of doing lighting, through different types of cars, different ways of building buildings. there are a lot of services where you can bring the energy for that service down quite substantially, some individual services even, bring it down by 90 percent. There are other services like how we make fertilizer, or how we do air transport, where the rooms for improvement are far, far less. And so, overall here, if we’re optimistic, we may get a reduction of a factor of three to even, perhaps, a factor of six. But for these first three factors now, we’ve gone from 26 billion to, at best, maybe 13 billion tons, and that just won’t cut it.
So let’s look at this fourth factor — this is going to be a key one — and this is the amount of CO2 put out per each unit of energy. And so the question is, can you actually get that to zero? If you burn coal, no. If you burn natural gas, no. Almost every way we make electricity today, except for the emerging renewables and nuclear, puts out CO2. And so, what we’re going to have to do at a global scale, is create a new system. And so, we need energy miracles.
Now, when I use the term miracle, I don’t mean something that’s impossible. The microprocessor is a miracle. The personal computer is a miracle. The internet and its services are a miracle. So, the people here have participated in the creation of many miracles. Usually, we don’t have a deadline, where you have to get the miracle by a certain date. Usually, you just kind of stand by, and some come along, some don’t. This is a case where we actually have to drive full speed and get a miracle in a pretty tight time line.
Now, I thought, how could I really capture this? Is there some kind of natural illustration, some demonstration that would grab people’s imagination here? I thought back to a year ago when I brought mosquitos, and somehow people enjoyed that. (Laughter) It really got them involved in the idea of, you know, there are people who live with mosquitos. So, with energy, all I could come up with is this. I decided that releasing fireflies would be my contribution to the environment here this year. So here we have some natural fireflies. I’m told they don’t bite, in fact, they might not even leave that jar. (Laughter)
Now, there’s all sorts gimmicky solutions like that one, but they don’t really add up to much. We need solutions, either one or several, that have unbelievable scale and unbelievable reliability, and, although there’s many directions people are seeking, I really only see five that can achieve the big numbers. I’ve left out tide, geothermal, fusion, biofuels. Those may make some contribution, and if they can do better than I expect, so much the better, but my key point here is that we’re going to have to work on each of these five, and we can’t give up any of them because they look daunting, because they all have significant challenges.
Let’s look first at the burning fossil fuels, either burning coal or burning natural gas. What you need to do there, seems like it might be simple, but it’s not, and that’s to take all the CO2, after you’ve burned it, going out the flue, pressurize it, create a liquid, put it somewhere, and hope it stays there. Now we have some pilot things that do this at the 60 to 80 percent level, but getting up to that full percentage, that will be very tricky, and agreeing on where these CO2 quantities should be put will be hard, but the toughest one here is this long term issue. Who’s going to be sure? Who’s going to guarantee something that is literally billions of times larger than any type of waste you think of in terms of nuclear or other things? This is a lot of volume. So that’s a tough one.
Next, would be nuclear. It also has three big problems. Cost, particularly in highly regulated countries, is high. The issue of the safety, really feeling good about nothing could go wrong, that, even though you have these human operators, that the fuel doesn’t get used for weapons. And then what do you do with the waste? And, although it’s not very large, there are a lot of concerns about that. People need to feel good about it. So three very tough problems that might be solvable, and so, should be worked on.
The last three of the five, I’ve grouped together. These are what people often refer to as the renewable sources. And they actually — although it’s great they don’t require fuel — they have some disadvantages. One is that the density of energy gathered in these technologies is dramatically less than a power plant. This is energy farming, so you’re talking about many square miles, thousands of time more area than you think of as a normal energy plant. Also, these are intermittent sources. The sun doesn’t shine all day, it doesn’t shine every day, and, likewise, the wind doesn’t blow all the time. And so, if you depend on these sources, you have to have some way of getting the energy during those time periods that it’s not available. So, we’ve got big cost challenges here. We have transmission challenges. For example, say this energy source is outside your country, you not only need the technology, but you have to deal with the risk of the energy coming from elsewhere.
And, finally, this storage problem. And, to dimensionalize this, I went through and looked at all the types of batteries that get made, for cars, for computers, for phones, for flashlights, for everything, and compared that to the amount of electrical energy the world uses, and what I found is that all the batteries we make now could store less than 10 minutes of all the energy. And so, in fact, we need a big breakthrough here, something that’s going to be a factor of a hundred better than the approaches we have now. It’s not impossible, but it’s not a very easy thing. Now, this shows up when you try to get the intermittent source to be above, say, 20 to 30 percent of what you’re using. If you’re counting on it for 100 percent, you need an incredible miracle battery.
Now, how we’re going to go forward on this: what’s the right approach? Is it a Manhattan project? What’s the thing that can get us there? Well, we need lots of companies working on this, hundreds. In each of these five paths, we need at least a hundred people. And a lot of them, you’ll look at and say they’re crazy. That’s good. And, I think, here in the TED group, we have many people who are already pursuing this. Bill Gross has several companies, including one called eSolar that has some great solar thermal technologies. Vinod Khosla’s investing in dozens of companies that are doing great things and have interesting possibilities, and I’m trying to help back that. Nathan Myhrvold and I actually are backing a company that, perhaps surprisingly, is actually taking the nuclear approach. There are some innovations in nuclear: modular, liquid. And innovation really stopped in this industry quite some ago, so the idea that there’s some good ideas laying around is not all that surprising.
The idea of Terrapower is that, instead of burning a part of uranium, the one percent, which is the U235, we decided, let’s burn the 99 percent, the U238. It is kind of a crazy idea. In fact, people had talked about it for a long time, but they could never simulate properly whether it would work or not, and so it’s through the advent of modern supercomputers that now you can simulate and see that, yes, with the right material’s approach, this looks like it would work.
And, because you’re burning that 99 percent, you have greatly improved cost profile. You actually burn up the waste, and you can actually use as fuel all the leftover waste from today’s reactors. So, instead of worrying about them, you just take that. It’s a great thing. It breathes this uranium as it goes along. So it’s kind of like a candle. You can see it’s a log there, often referred to as a traveling wave reactor. In terms of fuel, this really solves the problem. I’ve got a picture here of a place in Kentucky. This is the left over, the 99 percent, where they’ve taken out the part they burn now, so it’s called depleted uranium. That would power the U.S. for hundreds of years. And, simply by filtering sea water in an inexpensive process, you’d have enough fuel for the entire lifetime of the rest of the planet.
So, you know, it’s got lots of challenges ahead, but it is an example of the many hundreds and hundreds of ideas that we need to move forward. So let’s think, how should we measure ourselves? What should our report card look like? Well, let’s go out to where we really need to get, and then look at the intermediate. For 2050, you’ve heard many people talk about this 80 percent reduction. That really is very important, that we get there. And that 20 percent will be used up by things going on in poor countries, still some agriculture. Hopefully, we will have cleaned up forestry, cement. So, to get to that 80 percent, the developed countries, including countries like China, will have had to switch their electricity generation altogether. So, the other grade is, are we deploying this zero-emission technology, have we deployed it in all the developed countries and we’re in the process of getting it elsewhere. That’s super important. That’s a key element of making that report card.
So, backing up from there, what should the 2020 report card look like? Well, again, it should have the two elements. We should go through these efficiency measures to start getting reductions. The less we emit, the less that sum will be of CO2, and, therefore, the less the temperature. But in some ways, the grade we get there, doing things that don’t get us all the way to the big reductions, is only equally, or maybe even slightly less, important than the other, which is the piece of innovation on these breakthroughs.
These breakthroughs, we need to move those at full speed, and we can measure that in terms of companies, pilot projects, regulatory things that have been changed. There’s a lot of great books that have been written about this. The Al Gore book, “Our Choice” and the David McKay book, “Sustainable Energy Without the Hot Air.” They really go through it and create a framework that this can be discussed broadly, because we need broad backing for this. There’s a lot that has to come together.
So this is a wish. It’s a very concrete wish that we invent this technology. If you gave me only one wish for the next 50 years, I could pick who’s president, I could pick a vaccine, which is something I love, or I could pick that this thing that’s half the cost with no CO2 gets invented, this is the wish I would pick. This is the one with the greatest impact. If we don’t get this wish, the division between the people who think short term and long term will be terrible, between the U.S. and China, between poor countries and rich, and most of all the lives of those two billion will be far worse.
So, what do we have to do? What am I appealing to you to step forward and drive? We need to go for more research funding. When countries get together in places like Copenhagen, they shouldn’t just discuss the CO2. They should discuss this innovation agenda, and you’d be stunned at the ridiculously low levels of spending on these innovative approaches. We do need the market incentives, CO2 tax, cap and trade, something that gets that price signal out there. We need to get the message out. We need to have this dialogue be a more rational, more understandable dialogue, including the steps that the government takes. This is an important wish, but it is one I think we can achieve.
Thank you. (Applause) Thank you.
Chris Anderson: Thank you. Thank you. (Applause) Thank you. Just so I understand more about Terrapower, right — I mean, first of all, can you give a sense of what scale of investment this is?
Bill Gates: To actually do the software, buy the supercomputer, hire all the great scientists, which we’ve done, that’s only tens of millions, and even once we test our materials out in a Russian reactor to make sure our materials work properly, then you’ll only be up in the hundreds of millions. The tough thing is building the pilot reactor, finding the several billion, finding the regulator, the location that will actually build the first one of these. Once you get the first one built, if it works as advertised, then it’s just clear as day, because the economics, the energy density, are so different than nuclear as we know it.
CA: And so, to understand it right, this involves building deep into the ground almost like a vertical kind of column of nuclear fuel, of this sort of spent uranium, and then the process starts at the top and kind of works down?
BG: That’s right. Today, you’re always refueling the reactor, so you have lots of people and lots of controls that can go wrong, that thing where you’re opening it up and moving things in and out. That’s not good. So, if you have very cheap fuel that you can put 60 years in — just think of it as a log — put it down and not have those same complexities. And it just sits there and burns for the sixty years, and then it’s done.
CA: It’s a nuclear power plant that is its own waste disposal solution.
BG: Yeah. Well, what happens with the waste, you can let it sit there — there’s a lot less waste under this approach — then you can actually take that, and put it into another one and burn that. And we start off actually by taking the waste that exists today, that’s sitting in these cooling pools or dry casking by reactor. That’s our fuel to begin with. So, the thing that’s been a problem from those reactors is actually what gets fed into ours, and you’re reducing the volume of the waste quite dramatically as you’re going through this process.
CA: But in your talking to different people around the world about the possibilities here, where is there most interest in actually doing something with this?
BG: Well, we haven’t picked a particular place, and there’s all these interesting disclosure rules about anything that’s called nuclear, so we’ve got a lot of interest, that people from the company have been in Russia, India, China. I’ve been back seeing the secretary of energy here, talking about how this fits into the energy agenda. So I’m optimistic. You know the French and Japanese have done some work. This is a variant on something that has been done. It’s an important advance, but it’s like a fast reactor, and a lot of countries have built them, so anybody who’s done a fast reactor, is a candidate to be where the first one gets built.
CA: So, in your mind, timescale and likelihood of actually taking something like this live?
BG: Well, we need, for one of these high-scale, electro-generation things that’s very cheap, we have 20 years to invent and then 20 years to deploy. That’s sort of the deadline that the environmental models have shown us that we have to meet. And, you know, Terrapower, if things go well, which is wishing for a lot, could easily meet that. And there are, fortunately now, dozens of companies, we need it to be hundreds, who, likewise, if their science goes well, if the funding for their pilot plants goes well, that they can compete for this. And it’s best if multiple succeed, because then you could use a mix of these things. We certainly need one to succeed.
CA: In terms of big-scale possible game changes, is this the biggest that you’re aware of out there?
BG: An energy breakthrough is the most important thing. It would have been, even without the environmental constraint, but the environmental constraint just makes it so much greater. In the nuclear space, there are other innovators. You know, we don’t know their work as well as we know this one, but the modular people, that’s a different approach. There’s a liquid type reactor, which seems a little hard, but maybe they say that about us. And so, there are different ones, but the beauty of this is a molecule of uranium has a million times as much energy as a molecule of, say, coal, and so, if you can deal with the negatives, which are essentially the radiation, the footprint and cost, the potential, in terms of effect on land and various things, is almost in a class of its own.
CA: If this doesn’t work, then what? Do we have to start taking emergency measures to try and keep the temperature of the earth stable?
BG: If you get into that situation, it’s like if you’ve been over-eating, and you’re about to have a heart-attack. Then where do you go? You may need heart surgery or something. There is a line of research on what’s called geoengineering, which are various techniques that would delay the heating to buy us 20 or 30 years to get our act together. Now, that’s just an insurance policy. You hope you don’t need to do that. Some people say you shouldn’t even work on the insurance policy because it might make you lazy, that you’ll keep eating because you know heart surgery will be there to save you. I’m not sure that’s wise, given the importance of the problem, but there’s now the geoengineering discussion about, should that be in the back pocket in case things happen faster, or this innovation goes a lot slower than we expect.
CA: Climate skeptics: if you had a sentence or two to say to them, how might you persuade them that they’re wrong?
BG: Well, unfortunately, the skeptics come in different camps. The ones who make scientific arguments are very few. Are they saying there’s negative feedback effects that have to do with clouds that offset things? There are very, very few things that they can even say there’s a chance in a million of those things. The main problem we have here is kind of like AIDS. You make the mistake now, and you pay for it a lot later.
And so, when you have all sorts of urgent problems, the idea of taking pain now that has to do with a gain later — and a somewhat uncertain pain thing. In fact, the IPCC report, that’s not necessarily the worst case, and there are people in the rich world who look at IPCC and say, okay, that isn’t that big of a deal. The fact is it’s that uncertain part that should move us towards this. But my dream here is that, if you can make it economic, and meet the CO2 constraints, then the skeptics say, okay, I don’t care that it doesn’t put out CO2, I kind of wish it did put out CO2, but I guess I’ll accept it because it’s cheaper than what’s come before. (Applause)
CA: And so, that would be your response to the Bjorn Lomborg argument, that basically if you spend all this energy trying to solve the CO2 problem, it’s going to take away all your other goals of trying to rid the world of poverty and malaria and so forth, [that] it’s a stupid waste of the Earth’s resources to put money towards that when there are better things we can do.
BG: Well, the actual spending on the R&D piece — say the U.S. should spend 10 billion a year more than it is right now — it’s not that dramatic. It shouldn’t take away from other things. The thing you get into big money on, and this, reasonable people can disagree, is when you have something that’s non-economic and you’re trying to fund that. That, to me, mostly is a waste. Unless you’re very close and you’re just funding the learning curve and it’s going to get very cheap. I believe we should try more things that have a potential to be far less expensive. If the trade-off you get into is, let’s make energy super expensive, then the rich can afford that. I mean, all of us here could pay five times as much for our energy and not change our lifestyle. The disaster is for that two billion.
And even Lomborg has changed. His shtick now is, why isn’t the R&D getting discussed more. He’s still, because of his earlier stuff, still associated with the skeptic camp, but he’s realized that’s a pretty lonely camp, and so, he’s making the R&D point. And so there is a thread of something that I think is appropriate. The R&D piece, it’s crazy how little it’s funded.
CA: Well Bill, I suspect I speak on the behalf of most people here to say, I really hope your wish comes true. Thank you so much.
BG: Thank you. (Applause)
