Ray Kurzweil: Solar Will Power the World in 16 Years
Solar power, driven by exponentially-increasing nanotechnology, will satisfy the entire world's energy needs in 16 years.
What's the Big Idea?
Solar power, driven by exponentially-increasing nanotechnology, will satisfy the entire world's need for energy in less than twenty years.
Why Is It Groundbreaking?
Currently, solar power supplies less than 1% of the world's energy needs, which has led many to disregard its future significance. Where they're wrong is that they fail to understand the exponential nature of technology, says eminent inventor and futurist Ray Kurzweil. Just like computer processing speed—which doubles every 18 months in accordance with Moore's law—the nanotechnology that drives innovations in solar power progresses exponentially, he says.
During his latest Big Think interview, Kurweil explained:
"Solar panels are coming down dramatically in cost per watt. And as a result of that, the total amount of solar energy is growing, not linearly, but exponentially. It’s doubling every 2 years and has been for 20 years. And again, it’s a very smooth curve. There’s all these arguments, subsidies and political battles and companies going bankrupt, they’re raising billions of dollars, but behind all that chaos is this very smooth progression."
So how far away is solar from meeting 100% of the world's energy needs? Eight doublings, says Kurzweil, which will take just 16 years. And supply is not an issue either, he adds: "After we double eight more times and we’re meeting all of the world’s energy needs through solar, we’ll be using 1 part in 10,000 of the sunlight that falls on the earth. And we could put efficient solar farms on a few percent of the unused deserts of the world and meet all of our energy needs."
Reducing this bold of a prediction to simple mathematics sounds absurd, but it has served Kurzweil in the past. Using this formula, he accurately predicted the fall of the Soviet Union, chessmaster Garry Kasparov's defeat to a robot, and the proliferation of the Internet—as well as over 100 other predictions. (He also says that humans will merge with machines in 2045!)
Why Should You Care?
Needless to say, the implications of cheap solar power would be truly staggering, revolutionizing virtually every aspect of life and geopolitics. Potentially dangerous nuclear power would become obsolete; dirty energy sources like coal and oil would be a thing of the past; and the world would no longer have to kowtow to corrupt governments that just happen to be resource-rich.
So many other global issues—like impending water and food crises—would also no longer be issues if a cheap, renewable energy source existed. "We’re awash with water, but most of it's salinated or dirty," says Kurzweil. We have the technology to desalinate and clean water, but it is very costly. Cheap solar would change that. If we had inexpensive energy, scientists could also grow hydroponic fruits and vegetables, supplying the growing demand for food and "recycling all the nutrients and materials so there's no ecological impact at all." They could even "grow meat without animals by cloning muscle tissue," eliminating the need for disastrous factory farming, he says.

— Solar was the fastest growing US energy sector in 2010
— Is China's solar sector overhyped or underhyped? Both!
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
The controversial herbicide is everywhere, apparently.
- U.S. PIRG tested 20 beers and wines, including organics, and found Roundup's active ingredient in almost all of them.
- A jury on August 2018 awarded a non-Hodgkin's lymphoma victim $289 million in Roundup damages.
- Bayer/Monsanto says Roundup is totally safe. Others disagree.
The pizza giant Domino's partners with a Silicon Valley startup to start delivering pizza by robots.
- Domino's partnered with the Silicon Valley startup Nuro to have robot cars deliver pizza.
- The trial run will begin in Houston later this year.
- The robots will be half a regular car and will need to be unlocked by a PIN code.
Would you have to tip robots? You might be answering that question sooner than you think as Domino's is about to start using robots for delivering pizza. Later this year a fleet of self-driving robotic vehicles will be spreading the joy of pizza throughout the Houston area for the famous pizza manufacturer, using delivery cars made by the Silicon Valley startup Nuro.
The startup, founded by Google veterans, raised $940 million in February and has already been delivering groceries for Kroger around Houston. Partnering with the pizza juggernaut Domino's, which delivers close to 3 million pizzas a day, is another logical step for the expanding drone car business.
Kevin Vasconi of Domino's explained in a press release that they see these specially-designed robots as "a valuable partner in our autonomous vehicle journey," adding "The opportunity to bring our customers the choice of an unmanned delivery experience, and our operators an additional delivery solution during a busy store rush, is an important part of our autonomous vehicle testing."
How will they work exactly? Nuro explained in its own press release that this "opportunity to use Nuro's autonomous delivery" will be available for some of the customers who order online. Once they opt in, they'll be able to track the car via an app. When the vehicle gets to them, the customers will use a special PIN code to unlock the pizza compartment.
Nuro and its competitors Udelv and Robomart have been focusing specifically on developing such "last-mile product delivery" machines, reports Arstechnica. Their specially-made R1 vehicle is about half the size of a regular passenger car and doesn't offer any room for a driver. This makes it safer and lighter too, with less potential to cause harm in case of an accident. It also sticks to a fairly low speed of under 25 miles an hour and slams on the breaks at the first sign of trouble.
What also helps such robot cars is "geofencing" technology which confines them to a limited area surrounding the store.
For now, the cars are still tracked around the neighborhoods by human-driven vehicles, with monitors to make sure nothing goes haywire. But these "chase cars" should be phased out eventually, an important milestone in the evolution of your robot pizza drivers.
