Many people believe that the future of mankind is bleak because the planet can’t sustain its growing population. They fear we are running out of resources and that ageing populations and healthcare costs will bankrupt countries. George Mason professor Tyler Cohen says that America has consumed all the low-hanging fruits of land, labor, and technology and that we are at a technological plateau—“the trees are barer than we would like to think”. He talks of a “great stagnation”. Military planners in many countries are preparing for wars over diminishing natural resources.
In my view, these pessimists are dead wrong. That is because this is the most innovative period in human history. Technologies in a range of fields are advancing exponentially and making it possible for entrepreneurs to do what only governments and big labs could do before: solve humanity’s grand challenges. My belief is that we will go from worrying about scarcity to debating how we share and distribute the bounty that we create. Imagine a world with unlimited food, water, and energy—in which we prevent disease rather than cure it and in which our lifespans increase along with our wisdom and knowledge. This is what is possible, not in future centuries, but in the next two decades.
In his New York Times bestseller, Abundance, XPrize and Singularity University founder Peter Diamandis tells the story of how aluminum went from a rare metal to something we wrap our food in. When the king of Siam hosted Napoleon III in the 1840s, writes Diamandis, the people working for Napoleon were served with silver utensils; those working for the king received gold; the king himself got aluminum—the rarest metal at the time. Aluminum was so valuable because it was extremely difficult to extract from bauxite—though it is one of the most abundant elements on Earth. And then electrolysis technology was invented—which used electricity to liberate aluminum from bauxite. It made aluminum inexpensive.
It isn’t just aluminum that has become abundant. So have electrical power, refrigeration, television, telephones, cars, and air conditioning. Two hundred years ago, kings and queens didn’t have these luxuries; today, even many people who are classified as poor in the U.S. do. This prosperity has not reached most of the developing world—yet. But the proliferation of mobile phones shows what is possible. Within 10 years, their numbers have gone from zero to nearly 1 billion in both India and China. Even the poorest villagers own them. Mobile phones changed the lives of millions of families who were cut off from each when they went to cities to work and they transformed society.
We are also making headway in solving the global water crisis. Waterborne viruses are responsible for the majority of disease in the developing world. There are predictions that countries such as India, China, and parts of the Middle East will run out of water and that wars will break out over supplies. This seems paradoxical: 71% of the earth’s surface is water, and sanitizing and converting seawater is as simple as boiling it and condensing the vapor. The problem is the cost of energy—it is prohibitively expensive to do this in quantity.
Two exciting solutions to the water problem are already working and ready to scale.
The first is a product by Dean Kamen called Slingshot. Kamen is the inventor of the Segway personal transporter, an insulin pump, and many other breakthroughs. Slingshot is a vapor-compression water-purification machine that can produce about 30 liters of 100% pure distilled water per hour using the same power as a hair dryer consumes. It can transform dirty water from any source: rivers, oceans, and even raw sewage. Slingshot has been under development for more than a decade and was recently tested by Coca-Cola in five towns in Ghana for six months. The devices worked flawlessly.
Kamen told me that he expects that Slingshot will cost less than $2000 when mass produced and will not require any maintenance or servicing for seven years. One device will produce enough clean water to support a village of 300 people. Coca Cola plans to test it in dozens of locations this year and will expects to roll it out on a larger scale next year. I hope that other organizations will also license the technology from Kamen and alleviate worldwide disease and suffering.
Another amazing product, by Alfredo Zolezzi of Chile Advanced Innovation Center that can sanitize 35 liters of water in five minutes at a cost per liter of less than 1/8 of a (U.S.) cent. This works by injecting water into a reaction chamber, where it achieves plasma state through a high-intensity electrical field. The microbiological content of the water is eliminated by electroporation, oxidation, ionization, UV and IR radiation and shockwaves. This technology won’t remove impurities like salt, arsenic, and heavy metals from water, but will kill bacteria. The system has been in operation for more than two years in a slum in Santiago, Chile. The inhabitants told me that not one person had gotten sick since they started using it—in stark contrast to how it used to be.
Zolezzi’s device has been successfully tested by various labs in Chile and is being tested in collaboration with the National Science Foundation (NSF) to determine its conformance to EPA guidelines. Zolezzi expects that mass-produced units which cost $500 will be able to sanitize up to 2500 liters per day, and smaller units, which cost $200 will be able to process 1000 liters or more. He says he is in discussions with several large corporations for the mass production and distribution of the technology pending the NSF validation.
Every month, we read about advancements in energy technologies. Despite all the negative press about solar, the price of solar panels (per watt) was 97.2 percent lower in 2012 than in 1975—and the downward trend is continuing. At these rates, within a decade, solar energy will cost much less than what we pay to our utility companies—which produce electricity from fossil fuels. Solar will achieve what is called “grid parity” in Europe and other parts of the world even sooner than in the U.S.
Last month, the most exciting news was from UCLA, where a small team of researchers developed a micro-scale graphene-based supercapacitor that can charge and discharge a hundred to a thousand times faster than current batteries. This could make it possible to fully charge your laptop in seconds and your electric car in a couple of minutes.
When we have unlimited clean water and unlimited renewable energy, we can produce unlimited amounts of food. Singapore is already growing food in vertical farms. A Silicon Valley company called Hampton Creek Foods is producing an egg substitute made from plants. Another startup, Modern Meadow, is using tissue-engineering technique to produce in-vitro leather and meat—without requiring the raising, slaughtering, and transporting animals. With methods such as these, we will need less—not more—land to feed the world’s population.
Discovery, application, and invention are also occurring in medicine, 3D printing, artificial intelligence, robotics, and many other fields that will change our lives and transform entire industries. I have described some of these in and in these articles.
So we have a lot to look forward to. But many risks and challenges lie ahead. With every good comes a bad. The same technologies that enable entrepreneurs to solve big problems also allow the bad guys to wreak havoc on a global scale. In this decade we will see new billion dollar businesses and trillion dollar industries emerge. At the same time, we will see current industry leaders—and entire industries—wiped out by technology advances. Witness Kodak's becoming a victim of the digital photography industry, which it had helped create, and RIM's and Yahoo's battles for survival—and how manufacturing was lost to China and is nowreturning to the U.S. These technology advances will create disruption and opportunity. The winners will be the visionaries who gasp the changes and lead the charge.
