A couple of Google engineers shocked the world last week by announcing that after working on the RE<C (Renewable Energy Cheaper Than Coal) Initiative for four years, they had concluded that renewable energy is never going to solve our carbon emissions problem.
In a widely read article in IEEE Spectrum, the prestigious journal published by the Institute of Electrical and Electronics Engineers, Ross Koningstein and David Fork announced that after working at improving renewables on the Google project, they had decided that it wasn’t worth pursuing. Google actually closed down RE<C in 2011, but the authors are just getting around to explaining why.
At the start of RE<C, we had shared the attitude of many stalwart environmentalists: We felt that with steady improvements to today’s renewable energy technologies, our society could stave off catastrophic climate change. We now know that to be a false hope.
Google’s abandonment of renewable energy raises the immediate question: What about the effort to reduce carbon emissions from vehicles? And here the news is much better.
Although everyone concentrates on coal and power plants, they regularly forget that half our carbon emissions come from vehicles. It’s typical that Google’s RE<C effort didn’t address what to do about our cars. It’s too complicated to try to control the emissions from 200 million point sources.
But what’s never discussed is the fuel that goes into these vehicles. It’s well known that ethanol and methanol cut carbon emissions compared with gasoline. That’s a good chunk of the battle right there. But it doesn’t even take into account the possibility of making both fuels from non-fossil-fuel resources, so that both would be all pluses on our carbon budget.
Ethanol, as currently produced in this country, is synthesized entirely from corn, so there is no fossil-fuel element involved. Ethanol currently takes up 10 percent of all the gasoline sold is this country, but it is currently marketed at 85 percent ethanol in the Midwest, with only a 15 percent element to guarantee starting on cold days.
Methanol is generally synthesized from natural gas, so there is still a fossil-fuel element there, but there is always the possibility of making methanol from non-fossil sources. Municipal waste could easily be converted directly to methanol.
And of course there is always the possibility of synthesizing ethanol and methanol using renewable energy. People always talk about storing wind or solar energy as hydrogen, but methanol would be easier to store than hydrogen since it is a liquid to begin with and not subject to leakage and escape. Methanol can be easily stored in our current infrastructure.
The Chinese are currently building six methanol plants in Texas and Louisiana to take advantage of all the natural gas being produced there. All this methanol is slated to be shipped by tankers back to China, where it will be used to boost China’s own methanol industry — and to run some of the 1 million methanol cars the Chinese have on the road.
Yes, the Chinese are far ahead of us when it comes to using methanol a substitute for oil. But there’s a scenario that will introduce methanol in the American auto industry. With all this methanol on hand in Texas and Louisiana, someone will install a pump on one of the premises for dispensing methanol. Cars at the site will use it. Then someone will say, “Hey, why don’t I use this in my car at home? It’s cheaper.” Before you know it, there will be a contingency to have the EPA decide that methanol can be used in automobile engines the same as ethanol is currently used. And in the end, we will have large quantities of methanol substituting for foreign oil.
Is it a dream? No more unrealistic than the dreams that kept the Google scientists occupied for four years.
It seems like a kind of Hollywood fantasy — autonomous little roadsters scooting in and out of traffic, breathlessly avoiding collisions and getting to their destination before anyone else.
Then again, it seems like the inevitable. If computers can perform medical diagnoses, accomplish instant translations for tourists and power Martian rovers, what’s so complicated about driving a car?
The self-driving car has gotten a lot of publicity lately. Google has a demonstration project and there have been the usual speculations about how long before self-drivers become a common sight. Four states have passed legislation allowing their operation and this month self-driving cars received the ultimate accolade of any new technology by being opposed by the Ralph Nader’s Consumer Watchdog, thereby joining fracking, nuclear power, GMO foods and other technological advances as being opposed by the Naderites.
Yet in truth, the idea of self-driving vehicles has been around for a long, long time. Experiments go back as far back as the 1920s. Engineers tried burying electric cables beneath the road to send signals that would keep cars on track. With the development of computers, however, research switched to autonomous vehicles with a dozen auto manufacturers and universities doing serious work.
In 1995, Carnegie Mellon University built an autonomous vehicle that traveled 3,100 miles cross-country for the “No Hands Across America” tour, with only minimal human intervention. In 2005, a Google vehicle equipped with 3D cameras, radar and a software package called Google Chauffeur won a $2 million prize in a Grand Challenge sponsored by the U.S. Department of Defense. In 2010, four self-driving vehicles designed at the University of Parma, Italy duplicated Marco Polo’s expedition by driving from Italy to China with only occasional intervention by their human drivers. Google’s fleet of a dozen self-driving cars has now logged 700,000 miles on public highways without experiencing any trouble. The only accident occurred when one of them was read-ended by another vehicle at a traffic light.
Indeed, as things stand now, the biggest obstacle to widespread adoption may be the predictable human reluctance to have the wheel taken out of their hands. One poll in Germany found that while 22 percent of respondents had a positive attitude toward driverless cars, 44 percent were skeptical and 24 percent were actively hostile toward the idea.
So aside from inspiring a hundred high school science projects and proving that computer geeks can do just about anything, what would be the advantage of self-driving vehicles? Here are a few of the possibilities:
Greater fuel efficiency: Advocates say that the precision achieved by automated vehicles in evening out traffic flows would cut down on national gasoline consumption. Instead of some cars dawdling in the fast lane while others weave in and out, traffic would follow a much more orderly pattern. Estimates are that a large fleet of self-driving vehicles could cut national fuel consumption by as much as 10 percent.
The advance of non-gasoline fuel systems: Since the experiments with trolley-like electronic tracks of the 1920s, self-driving systems have been associated with electric cars. While it will be perfectly possible to mount self-driving equipment on a gasoline-powered car, the “wave of the future” seems to be associated with non-gasoline vehicles. Google’s self-driver runs on electricity as do nearly all other experimental models.
Fewer accidents: Although humans may be reluctant to admit it, the vast majority of accidents are caused by driver error. The 360-degree visibility and unblinking vigilance of self-drivers could be a vast improvement. Many new cars are already beginning to incorporate some of the features with rear-view cameras and automatic braking. The 2014 Mercedes S-class offers options for self-parking, automatic accident avoidance and driver fatigue detection. One website that projects the self-driving future even suggests that the main job losses would be among: 1) hospital emergency room services, 2) auto repair shops and 3) trial lawyers specializing in auto accidents!
Peer-to-peer sharing of traffic information: The end point of self-driving would be a peer-to-peer information-sharing system whereby individual vehicles would be warned of congestion and traffic tie-ups and routed away from them. A 2010 study conducted by the National Highway Traffic Safety Administration projected that an amazing 80 percent of all traffic accidents could be avoided by such a peer-to-peer system that smooth out traffic patterns and prevent cars from bumping into each other on congested highways.
More efficient traffic lights: How much time and gas is wasted by cars waiting for the light to change when no cars are coming in the crossing lane? Computerized systems linked to self-drivers could do wonders to hasten traffic flow and ease the time needlessly spent waiting for red lights.
Driving services for people who cannot drive: Many elderly and handicapped people cannot drive under ordinary circumstances, but could manage a vehicle in which they program it to tell it where they want to go. One of Google’s first early adapters was Steve Mahan, a California resident who is legally blind. This YouTube video shows him running a series of errands through his neighborhood, including a visit to a drive-in taco stand. All this might seem that it would increase driving and add to the nation’s fuel consumption until you consider that many of these people are already serviced by elaborate jitney systems that spend a great deal of time making empty runs. Once again, self-drivers would add precision and efficiency to the system.
Mass public transit — the possibility of a whole new personal mobility system: At the end point of this new technology is the vision of a whole new transportation system where far fewer vehicles would be needed to get people where they want to go. Driving this vision is the statistic that the average car is parked 90 percent of the time. If these vehicles could be put to more efficient use — something along the lines of bike-sharing on city streets — then the need for vehicles might be drastically reduced. Particularly in urban settings, more efficient matching of vehicles and passengers would cut down on the need for street parking. Uber, the San Francisco company that matches passengers with drivers of vehicles for hire, is now operating in 200 cities in 42 countries around the globe. The fuel savings it creates through matching efficiency are phenomenal.
Much of the fruits of these innovations are still in the future, but don’t put it past innovators like Google to make it happen quickly. In 2012 the Nevada Department of Motor Vehicles issued the country’s first license to a Toyota Prius modified with Google technology. Florida and Michigan have also issued permits for road testing. Next January, Google will launch 200 gumdrop-shaped vehicles completely void of steering wheel, brake and gas pedal that will begin cruising the streets of Mountain View, Calif., in an experiment supervised by the California DMV.
The future may be closer than we think.
Elon Musk doesn’t mind making comparisons between himself and Henry Ford. Others are doing it as well.
In announcing his plans for a “Gigafactory” to manufacture batteries for a fleet of 500,000 Teslas, Musk said it would be like Ford opening his famous River Rouge plant, the move that signaled the birth of mass production.
The founder of PayPal and current titular leader of Silicon Valley (now that Steve Jobs is gone), Musk is not one for small measures. The factory he is now dangling before four western states would produce more lithium-ion batteries than are now being produced in the entire world. And that’s not all. He’s designing his new operation to mesh with another cutting-edge, non-fossil-fuel energy technology – solar storage. His partner will be SolarCity (where Musk sits on the board), run by his cousin Lyndon Rive. Together they are looking beyond mere automobile propulsion and are envisioning a world where all this solar and wind energy stuff comes true.
So, is Musk a modern-day Prometheus, bringing the fire to propel an entirely new transportation system? Or, as many critics charge, is he just conning investors onto a leaky vessel that is eventually going to crash upon the shores of reality? As the saying goes, we report, you decide.
One investor that is already showing some qualms is Panasonic, which already supplies Tesla with all its batteries and would presumably help the company fill the gap between the $2 billion it just raised from a convertible-bond offering and the $5 billion needed to build the plant. “Our approach is to make investments step by step,” Panasonic President Kazuhiro Tsuga told reporters at a briefing in Tokyo last week. “Elon plans to produce more affordable models besides [the] Model S, and I understand his thinking and would like to cooperate as much as we can. But the investment risk is definitely larger.” Of course, this is Japan, where “the nail that sticks out gets hammered down.” Corporate executives are not known for sticking their necks out.
Another possible investor is Apple, which has mountains of cash and, at least under Steve Jobs, was always willing to jump into some new field – music, cell phones – to try to set it straight. This is a little more ambitious than the Lisa or the iPod and Jobs is no longer around to steer the ship, but Apple and Musk officials held a meeting last spring that stirred a lot of talk about a possible merger. A much more likely scenario, according to several commentators, is that Apple would become a major player in the Gigafactory.
And a Gigafactory it will be. Consider this. The three largest battery factories in the country right now are:
1) The LG Chem factory in Holland, Mich. is 600,000 square feet, employs 125 people and produces 1 gigawatt hour (GWH) of battery output per year.
2) The Nissan factory in Smyrna, Tenn. is a 475,000 square-foot facility with 300 employees puts out 4.8 GWH per year.
3) A123 Systems’ battery factory in Livonia, Mich. is 291,000 square feet, employs 400 people and produces 0.6 GWH per year.
Both LG and Nissan received stimulus grants from the Department of Energy, built to overcapacity and are now operating part-time.
Now here’s what Musk is proposing. His Gigafactory would cover 10 million square feet, employ 6,500 people and produce 35 GWH per year of battery power. Basically, Musk’s operation is going to be ten times better anything ever built before, at a time that most of what exists isn’t even running fulltime. Does that sound like something of Henry-Ford proportions? Similar to Ford’s $5 a day wages, perhaps?
There are, of course, people who think all of this is crazy. In the Wall Street Journal blog, “Will Tesla’s $5 Billion Gigafactory Make a Battery Nobody Else Wants?,” columnist Mike Ramsey expresses skepticism over whether Tesla’s strategy of using larger numbers of smaller lithium-ion is the right approach. “Every other carmaker is using far fewer, much larger batteries,” he wrote. “Tesla’s methodology – incorrectly derided in its early days as simply using laptop batteries — has allowed it to get consumer electronics prices for batteries while companies like General Motors Co. and Nissan Motor Co. work to drive down costs without the full benefits of scale. Despite this ability to lower costs, no other company is following Tesla’s lead. Indeed, in speaking with numerous battery experts at the International Battery Seminar and Exhibit in Ft. Lauderdale a few weeks ago, they said that the larger cells would eventually prove to be as cost effective, and have better safety and durability. This offers a reason why other automakers haven’t gone down the same path.
But Musk has managed to produce a car that has a range of 200 miles, while the Leaf has a range of 85 miles and the Chevy Spark barely makes 82. Musk must be doing something right. And with Texas, Arizona, Nevada and New Mexico all vying to be the site of the Gigafactory, it’s more than likely that the winning state will be kicking in something as well. So, the factory seems likely to get built, even on the scheduled 2017 rollout that Tesla has projected.
At that point, Musk will have the capacity to produce batteries to go in 500,000 editions of the Tesla Model E, which he says will sell for $35,000. Sales of the $100,000 Model S were 22,000 last year. Does this guy think big or what?
To date, Silicon Valley doesn’t have a terribly good record on energy projects. Since Kleiner Perkins Caufield & Byers fell under Al Gore’s spell in 2006, its earnings have been virtually flat and the firm is now edging away from solar and wind investments. Venture capitalist Vinod Khosla’s spotty record in renewables was also the subject of a recent 60 Minutes segment. But, as venture capitalists say, it only takes one big success to make up for all the failures.
Will Tesla’s Model E be the revolutionary technology that, at last, starts making a dent in oil’s grip on the transportation sector? At least one investor has faith. “I’d rather leave all my money to Elon Musk that give it to charity,” was the recent evaluation of multi-billionaire Google founder Larry Page.
