SAN FRANCISCO--Technology giant Intel is seeing big opportunities in wind forecasting for power generation, and in information management for electric vehicles, John Skinner, Intel's director of marketing for its Eco-Technology division, said Tuesday.
Intel already sells microprocessors to wind turbine manufacturers and this would be an expansion of that business.
Adoption of wide-scale wind power would rely on accurate forecasting, such as when the wind would blow and how fast, he said.
"There's a lot of opportunities for sensor technology and high-performance computing," he said in an interview on the sidelines of an industry conference. "We are starting to explore it."
Intel has said it wants to grow its processor and software presence outside the traditional markets and has invested in a number of green technology companies through its venture capital arm, Intel Capital.
Wind and solar power have gained in popularity but mass adoption has been hindered by the fact that neither power works around the clock. Solar panels don't work at night and wind turbines only spin when the wind blows.
"We see numerical forecasting [in wind] as very interesting opportunity," he said, adding that "every extra bit of granularity and predictability" on wind power is very valuable.
Another sector that Intel is eyeing is electric vehicles.
Skinner said that transportation industry is "very ripe" for the application of microprocessors.
"Electric vehicles are going to contain a lot of electronics," he said, adding that Intel could see itself being involved certain aspects of the electric car such as energy management and range prediction.
"It would be an extension of our business in telematics," he said.

A group of CEOs on Monday came out favor of a regional roll-out of electric vehicles in up to eight cities to demonstrate the viability of the technology and incubate the fledgling industry.
The Electricifcation Coalition held a press conference in Washington, D.C. and released an Electrification Roadmap, which prescribes the business and policy steps required to ramp up electric vehicle adoption.
There are 13 members of the coalition, including the CEOs of Nissan Motor, FedEx, Pacific Gas & Electric, and battery maker A123 Systems. The coalition was spun out of Securing America's Future Energy, a lobbying group focused on reducing U.S. imports of oil.
The Electrification Coalition argues that light-duty electric vehicles are the only technology that can cut oil imports and reduce carbon emissions in the near term. Its report (click for link) focuses on what's required to make electric cars available at large scale.
"I think we have the conditions for the mass market. But it's going to take more time," said Carlos Ghosn, the president and CEO of Nissan. "The investments to be made are huge. To make 50,000 batteries is a $250 million investment."
Of all the major automakers, Nissan is the most bullish on electrification. It is releasing an all-electric family sedan called the Leaf in the U.S. and Japan next year. It projects that 10 percent of new cars sales in 2020 will be electric, which is higher than most analysts' projections.
The shift presents challenges to auto makers that are unsure of consumer acceptance. Utilities and municipalities need to prepare in order to make these vehicles more consumer-friendly but they, too, are unsure what the volume of sales will be.
To take some uncertainly out of the picture, the Electrification Coalition advocates a "foothold strategy." Six to eight cities would create a number of incentives for electric vehicles, such as preferential parking and public charging stations. They would apply for government incentives and then test out the system to help bring electric cars to "critical mass," explained David Crane, the president and CEO of power generator NRG Energy.
In the first phase, the plan calls for getting 50,000 to 100,000 light-duty plug-in vehicles on the road per year in certain areas starting next year and then expand to 25 cities. Its report sets a target of having 25 percent of new vehicle sales be plug-ins by 2020, which is 5 million vehicles. A jump to 90 percent of new vehicle sales being plug-ins by 2030 would represent roughly 17 million units, according to data from consulting company PRTM.
For consumers, batteries should be owned and financed separately from the car itself, Crane said. Because batteries are an expensive component that makes it more expensive than a comparably-sized gasoline car, auto makers, including Nissan, are looking at ways to keep monthly car payments roughly the same by leasing batteries.
Governments around the world have established financial incentives for electric vehicles because it improves national security and addresses environmental problems, Nissan's Ghosn said. He noted that France, the U.S., and Japan each have established a tax credit of about $7,500 to consumers who buy an electric car.
In addition to federal tax credits, the coalition endorses incentives for municipalities dedicated to bringing in electric vehicles. Also required is technology to allow consumers to charge at off-peak times.
Speakers at the coalition launch also underscored the economic reasons for which governments are pushing electrification. Reducing oil imports would mean that billions of dollars of U.S. wealth would stop being exported, said Crane.
Government programs to drive investing in electric vehicle manufacturing also help the U.S. auto industry adapt to emerging technologies.
"We can do this. This is something we have the ingenuity for--we have enough innovation. What we need to do is capture that and use that to our advantage to build factories," said David Vieau, the CEO of A123 Systems.

LOS ANGELES--Nissan Motor will keep the price of its upcoming battery-powered Leaf competitive with similar-size cars and expects to make money on the vehicle despite the cost of its launch, said Chief Executive Carlos Ghosn on Friday.
The five-passenger hatchback, which is being designed to have an all-electric range of 100 miles, would cost only 1 percent to 2 percent more than traditional combustion engine vehicles in its class, he said.
"On the pricing of the vehicle it is too early to say, but there will be no surprise," Ghosn said. "We know it will be the key to the mass market."
Nissan has not disclosed pricing on the Leaf, but has said it expects the car to be the first affordable, mass-market electric car when it goes on sale in the United States, Japan, and Europe by the end of 2010.
Nissan has bet heavily on electric cars and expects that by 2020, 10 percent of the world car market will be for electric vehicles. It has announced a series of partnerships with utilities and government agencies to advance technology where it believes it has a chance of seizing market leadership.
The automaker said on Friday that it would cooperate with Houston-based Reliant Energy, a subsidiary of NRG Energy in developing a charging infrastructure for electric cars at homes and near office buildings.
Ghosn, who was speaking to reporters at an event outside Dodger Stadium to kick off a U.S. marketing tour for the Leaf, said Nissan would roll out the car slowly in the U.S. market to get more feedback from consumers.
The Leaf is designed to draw power from a battery-pack developed with Japan's NEC that Nissan has said can be recharged overnight on a 220-volt connection.
Nissan has taken $1.6 billion in low-cost loans from the U.S. Department of Energy to revamp a plant in Smyrna, Tenn., to make the Leaf. The first models in the U.S. market will be imported from Japan.
Nissan's rivals have pushed competing battery-powered technologies. Toyota Motor dominates the market for traditional hybrids and has floated plans for a broader range of vehicles under the Prius name.
Others, such as General Motors and Fisker Automotive, are banking on plug-in designs that rely on batteries for short drives but also include a gasoline-powered generator to recharge the battery on longer trips.
"We think this technology is a technology we control, but we need scale. And that is why today we are building an overall capacity between Renault and Nissan of 500,000 cars and batteries a year that we are installing between the United States, Europe, and Japan," Ghosn told reporters.
"Hopefully, we are going to move upward. Because it is not about one car, it is about four cars for Nissan and four cars for Renault."
Leasing the car's batteries is a way to bring down the upfront cost, analysts say, and Ghosn said he preferred to lease batteries because Nissan can have control over replacement as technology improves.
But while Nissan plans to lease batteries on a global scale, executives said that they are still studying whether to do so in the U.S. market.
Ghosn said the Leaf would be profitable for Nissan. By contrast, GM has said it does not expect to make money on the first sales of its plug-in Volt, expected to be priced near $40,000 when it launches in late 2010.
"We will make money out of the Leaf," Ghosn said. "We have to make money, because if we don't make money the technology is condemned."
He added: "Everything we are doing today--and that is one of the reasons we are negotiating with the government--is to make sure this technology can continue to develop. We have a reasonable return on our investments and continue to develop the technology. And the consumer has to pay a reasonable price."

Green Plug's twist port universal charger.
(Credit: Green Plug)Start-ups Green Plug and WiPower are working together on a universal wireless charger for portable devices, the companies said Thursday.
The partnership makes sense since GreenPlug has developed a protocol to allow power sources and portable devices to communicate, while WiPower has invented technology to transmit power wirelessly over short distances.
Green Plug's universal chargers allow portable electronic devices containing its embedded Greentalk chip to be charged from a universal port. Once a device is plugged in to a Green Plug charger port, the charger's Greentalk protocol reads the chip inside the device to determine the power supply needed to charge it. It then tunes its power output to charge the device accordingly.
WiPower has a developed technology that can transmit power over short distances wirelessly. You can place a device on a WiPower pad in any position, and it automatically begins recharging.
Powermat makes a wireless charging dock that works with cases made for specific devices.
(Credit: Powermat)Here's the caveat. For this to become a reality, manufacturers must opt to embed Greentalk chips into their products instead of offering individual power adapters for each model they make.
The idea is considered green because millions of chargers are thrown away each year when people buy new devices and discard the old chargers. Embracing the Greentalk chip could theoretically prevent millions of chargers from being manufactured in the first place.
The idea is not entirely unique, though. Powermat makes a pad for wirelessy charging any Powermat-enabled device. In order to work with it, the device must be placed inside a special case that houses a Powermat receiver programmed to work with the charger and a specific device's needs. Users can also buy a cube with eight different types of ports that can sit on the mat and be plugged in to compatible devices.
This radio-controlled model car is powered by a battery that can be refilled with an electrolytic fluid.
(Credit: Fraunhofer Institute)Imagine that you're driving your future electric car down the road, and it gives you a low battery warning. What do you do? Instead of spending a few hours at a recharging station, new battery technology being developed by the Fraunhofer Institute in Germany would let you pull into a service station and refill the battery with an electrolytic liquid.
The Fraunhofer Institute is using a redox flow battery, a type of cell that uses two electrolytic fluids exchanging protons through a membrane. This process generates electricity. Although this type of battery isn't new, the Fraunhofer Institute improved the energy density, making it equivalent to that of a lithium ion battery.
In production cars such as the Tesla Roadster, the lithium ion battery pack requires almost four hours from a quick charger to go about 200 miles. A redox flow battery service station would pump out the discharged electrolytic fluid from your car's battery, replacing it with charged fluid, most likely in a matter of minutes. Instead of getting new shipments of charged fluid, similar to how current service stations rely on tankers full of gasoline, the station could merely recharge the fluid on its premises, even using solar cells or a wind turbine.
Other companies are working on redox flow battery technology for stationary energy storage.
For 2010, Tesla updates its electric Roadster with a Sport version, featuring faster acceleration.

Tesla often emphasizes that it works more like a Silicon Valley technology company than a traditional car company. And the company just proved it by delivering a model update to the Tesla Roadster for 2010. Remember, the Roadster has only been in production for one year, but in that time Tesla completely redesigned the interior, while at the same time adding new materials to reduce cabin noise. Model updates from other automakers often take five years.
We spent a day with the 2010 Tesla Roadster Sport, enjoying its unique driving experience and finding these updates made the previous generation car seem like something hacked together in a garage. Where the previous car had a fussy little lever for putting it in drive, the new car uses push buttons. To check battery statistics and change the drive mode, you had to use a touch screen by your left knee. That touch screen has been moved to the center of the dashboard. And in a real step toward convenience, the Tesla Roadster now comes with a glove box.
The rear air intakes get clear coat carbon fiber inserts.
(Credit: Josh Miller/CNET)Externally, the casual observer won't see much difference. The Tesla Roadster uses the same Lotus-sourced body clad in carbon fiber. But the carbon fiber stands out more, as clear-coat panels make up the hood, spoiler, and even the insets in the rear air intakes. The suspension is now adjustable for comfort or sport, and the all-new Sport version of the Roadster uses an upgraded power train that rockets it to 60 mph in 3.7 seconds, faster than the standard Roadster's 3.9 second time.

In the past few weeks, I've had an opportunity to experience the cutting edge in plug-in electric vehicle technology. In some cases, you'd think you're just driving a regular car.
The bulk of production plug-in electric vehicles available now are either utility trucks, small cars that top out at 25 miles per hour, or the pricey Tesla Roadster sports car. Now automakers are building plug-in sedans and SUVs with lithium ion batteries designed for the mass market.
Judging from the cars I've driven, automakers are trying to strike a balance between enticing consumers with new technology but not asking them to make sacrifices. So even though electrification is shaking up the auto industry, the biggest learning curve for owners may be around fueling rather than driving. And if the goal is to make plug-ins mainstream, that's probably a good thing.
Consider the electric Ford Focus which is due out in 2011. It runs entirely on batteries for a range of about 100 miles and will be manufactured side-by-side with the gasoline edition.
During my drive two weeks ago, I was eager to feel the acceleration. Vehicles that run off electric motors have "instant torque," which means you get the car's top acceleration at all speeds. The Focus was indeed zippy and responsive, but when I asked if it was better than the gasoline Focus, Ford's director of global electrification Nancy Gioia told me that it'd be the same--on purpose.
Ford dialed back the potential acceleration of the electric Focus so drivers can expect the same from the gasoline and electric versions. The same is true for braking.
"That makes the technology less scary and more familiar--and, actually, safer. Because if you jump from an (electric car) to a regular car, you don't want to have to remember very different (conditions)," she said. Limiting the maximum available acceleration also saves the batteries to help deliver on expected range.
Electric drive
Another car in the all-electric category is the Think City, made by Think of Norway, which I got a chance to drive last week. From a design point of view, it's almost the polar opposite of the high-end Tesla Roadster. The Think City can go about 100 miles on its batteries and it's highway capable with a top speed of 60 miles per hour. In its first iteration, it only has two seats in the front and a hatchback.
Once again, I found the acceleration pretty good and responsive during my quick loop around a parking lot roof. But don't expect sports car-caliber handling. It struck me as a car simply designed to get you from one place to the next, but on electric charge. The company expects to start selling the Think City in Europe later this year and build a plant for the U.S. market next year.
Nissan, Tesla Motors, and Coda Automotive are among the other automakers betting on all-electric sedans. The thinking is that the limited range is acceptable for people who would rather fuel up on electricity than oil for their daily commutes. GM executives, for example, project that more than 90 percent of drivers could do 90 percent of their driving in electric mode.
If you drive 50 miles a day, all-electric cars probably aren't the best fit for your primary car. That said, a 100-mile range with daily charging can meet a lot of Americans' daily driving needs and rental cars are always available for long road trips.
Auto industry executives say it will be substantially cheaper to drive on an electric charge, but the high cost of batteries and power electronics raise the upfront cost. Ford's electric Focus, for example, will cost more than the gasoline version, although it should be eligible for a tax credit for plug-ins. The Chevy Volt is said to cost about $40,000, and Nissan's Leaf is said to cost in the $25,000 to $35,000 range, although the company is looking at options, such as battery leasing, to lower that upfront cost.
Plug-in hybrids
Analysts project electrics to be a very small slice of the overall market for hybrids and electric vehicles in the next five years because of the limitations on range and the anticipated higher cost associated with the new technology.
Sales of hybrids, meanwhile, are projected to grow. But what remains to be seen is how much traction plug-in hybrids will get. Toyota, Ford, and General Motors are preparing plug-in hybrids, which will start arriving in showrooms over the next two or three years. Initially, plug-in hybrids are being tested with fleet operators.
After taking the Focus for a ride, I took a spin in a prototype of a plug-in hybrid Ford Escape SUV being tested by utilities gauging the impact of plug-ins on the grid. The driving, again, was familiar; acceleration, handling, and the interior is all what I'd expect in an SUV. What was different is that I was quickly drawn to the fuel-efficiency feedback system.
In this case, the Escape drives mostly on its 10 kilowatt-hour battery (compared to a 1.5 kilowatt-hour battery in a regular hybrid) for the first 30 miles or so. But when you need an extra boost of power, the gasoline engine will kick in, which you can hear and see on the in-car display.
The big advantage of gas-electric vehicles, of course, is that you can fuel up away from an electrical socket. Overall, fuel economy will improve the more often you can charge up. In a test of its fleet of converted plug-in Priuses, Idaho National Labs found that its average mileage was 55 miles per gallon, but fuel economy dropped significantly if cars were not charged every day.
The technological twist on the plug-in hybrids is the extended-range electric vehicle or a series hybrid--an approach being used by the Chevy Volt and Fisker Automotive luxury sedans. In this case, it's the electric motor that moves the car all the time and the gas engine is used to run a generator for the motor. When I was taken for a drive in the Volt by a GM auto engineer this summer, I found the Volt had a lot of pep and handled turns well.
Having driven a number of plug-in vehicle variants over the past year, it's clear that these cars will work just fine for everyday driving. The technology of lithium ion batteries leaves plenty of room for both utilitarian and performance cars. Nobody can say how much more the average consumer will be willing to pay for fuel efficiency from the new technology, but the biggest change to daily habits may come when drivers fuel up by plugging in rather than filling 'er up.
Fisker's first car, the Karma, is set to be released next year. Its Delaware plant is set to make its next luxury car, which will also be a plug-in hybrid.
(Credit: Fisker Automotive)Upstart carmaker Fisker Automotive on Tuesday said it will purchase a plant in Wilmington, Del., to make a plug-in hybrid sedan.
The facility, which used to be a General Motors factory, will begin manufacturing a plug-in hybrid in late 2012, which the company expects will cost almost $40,000 after federal tax credits. U.S. Vice President Joe Biden and Delaware Gov. Jack Markell are scheduled to speak at an announcement ceremony on Tuesday morning.
Production of Fisker's "family-oriented" car, called Project Nina, will result in 2,000 factory jobs. The company anticipates making 75,000 to 100,000 cars per year by 2014. "Wilmington is perfect for high-quality, low-volume production," CEO Henrik Fisker said in a statement.
The Wilmington assembly plant, closed in July this year, produced a handful of relatively low-volume cars from GM's shed brands, including the Pontiac Solstice and Saturn Sky.
Fisker's first car, called the Karma, is a high-end luxury car priced at about $88,000. The Karma, which is will be manufactured in Europe, will be available in the middle of next year.
Fisker Automotive received $528.7 million from a Department of Energy loan in September, which will fund the purchase of the factory from GM. The company expects to buy the plant for $18 million and spend another $175 million to retool the factory over the next three years.
The technology used by Fisker, called an extended-range electric vehicle or series hybrid, is similar to that used by General Motors' Chevy Volt. The Karma will go 50 miles on batteries, and then a gasoline engine will run a generator for longer rides, for a total range 300 miles.
DETROIT--For plug-in electric cars, it's no longer a question of if. It's a question of when and how.
After many years of buildup, plug-in vehicles aimed at mainstream buyers are set to come to the market starting next year. But even with the momentum around plug-ins, many questions remain unanswered over how this technology transition will impact the ailing auto industry and how the cars will received by consumers.
"You have the feeling that we're at the beginning of something that could be very special," said David Cole, the chairman of the Center for Automotive Research, which is funded by government and corporate sources, during the opening of the Business of Plugging In conference here on Tuesday. "There are a great many uncertainties, but we have to recognize that the key invention is here with the lithium ion battery."
The sold-out conference, which attracted about 600 people, represented the varied groups needed to deliver these vehicles: automakers and supply chain suppliers, electricity utilities, policy makers, tech entrepreneurs, and investors.
Regardless of the initial volumes of electric-vehicle sales, the stakes in this shift are high. Electric vehicles promise to reduce pollution from transportation, decrease oil imports, and provide economic opportunity for a broad number of businesses.
Compared to biofuels or hydrogen fuel cell technologies, the large automakers and several start-ups have coalesced around electrification, to a greater extent. But there still remains the question of how much money consumers are willing to pay and how easily they can adjust strong habits.
"We've placed big bets in this area...(but) the question is: will consumers want these vehicles?" Bill Ford, the chairman of Ford Motor, said during a Wednesday talk. "The short answer is, it depends on how many trade-offs they need to make...and I think customers aren't prepared to make many trade-offs at all."
Hybrid premium
Plug-in cars come in various forms, but the larger battery means a higher purchase price than today's hybrids or equivalent gasoline models. If consumers are going to accept that up-front cost, automakers need to convince them that owning an electric car is cheaper in the long run. One idea that automakers are seriously considering is leasing batteries, which could make the monthly payments for a new electric car comparable to a gasoline version.
The actual prices for many cars aren't yet known, since companies have not yet decided. Nissan's all-electric Leaf sedan, set for its U.S. debut next month and availability next year, is said to be in the $25,000 to $30,000 range. Industry executives estimate that the electric Chevy Volt, due late next year, will be in the $40,000 range.
Fueling up an electric car is less expensive than running the equivalent gasoline-only vehicle, and auto industry executives say the maintenance is simpler on electric drives (no more oil changes, for example). Jonathan Lauckner, General Motors' vice president of global program management, on Tuesday said the cost per mile of the Volt could be a sixth of a gasoline car's, offering as much as $1,500 a year in savings. Those savings get better, if gas prices go up and if drivers can charge up more than once a day.
And consumers want this information. Surveys show that consumers are drawn to plug-ins for environmental reasons, but fuel savings are actually more important, according to a survey of U.S. drivers done by Ernst & Young. Safety, of course, is another high priority.
"We've always had a disconnect between the purchase price and the usage cost, where consumers way undervalue the usage costs, which will continue to be a problem here," Richard Curtain, of the Institute of Social Research at the University of Michigan, said during a panel on Wednesday. "If it got to less than a $5,000 premium, that would allay many of the concerns of the consumer."
Industry executives say volume production, a goal of the Department of Energy's $2.4 billion grant program launched in August, will help bring down costs in the coming years, much the way hybrid components fell in price. But that up-front premium is tough to totally erase, given that electrification is competing with a deeply entrenched technology: the internal combustion engine.
Battery improvements will help the cost picture as well. Many companies are working on batteries--a new generation of lithium ion batteries and other chemistries--that can pack more energy. More "energy-dense" batteries means that drivers will get a longer driving range from a battery of a given size. Ultracapacitors, another storage method, have also been proposed as way to work with batteries in vehicles.
Technology horse race
The different routes automakers are taking to electrification affects costs. General Motors' Chevy Volt has generated plenty of buzz, but company executives say its design will make at least the first generation of the car pricey. GM hopes to wring thousands of dollars from the Volt power train, notably the battery and power electronics in the second generation of the car.
Fisker Automotive, a start-up that received a $528 million loan from the Department of Energy, is using a similar power train for its planned Karma and Nina high-end luxury cars. Called an extended-range electric vehicle or a series hybrid, these cars will run on battery charge only in the beginning--40 miles in the case of the Volt--and then use an internal combustion engine to operate a generator for the electric motor on longer trips.
A handful of automakers--Ford, Nissan, Think, and Coda Automotive among them--are making all-electric vehicles, also called battery-electric vehicles. Because of the limited range of about 80 miles to 100 miles, these cars are being sold as second cars in the United States or Europe or for city driving.
By contrast, Toyota, which has already sold millions of Priuses, believes that the way to sell large volumes of plug-in cars is to build on the existing hybrid technology, where batteries and the gasoline engine both propel the car.
"We think that blended (mode) is going to be the only way to reach the cost parity that the consumer is going to want," said Justin Ward, the advanced power train program manager at the Toyota Technical Center. "There (are) a lot of high-end cars, but how high do you go before it becomes unattainable for the general consumer?"
Infrastructure
Electric and hybrid cars aren't going to take over the market any time soon, because of cost and because they face competition from more efficient gasoline engines and diesels. Market researcher IHS Global Insight projects that pure-electric and range-extended electric vehicles will account for just more than 1 percent of the total market by 2014, with hybrids and plug-in hybrids being nearly 21 percent.
But even though plug-ins of various types will be a niche in the early years, utilities need to start preparing now. On a local level, utility executives are concerned that just a few plug-in cars, which can pull as much juice as a whole house when charging, will strain local power grids. That's particularly true, if consumers install faster 220-volt charging ports, which will cut charge time to about two or three hours, from six or eight.
The way to avoid stressing the grid is to charge cars at off-peak times, utility executives say. Pacific Gas & Electric, considered one of the most aggressive utilities in embracing new technologies, plans to offer customers a 220-volt charger that has a timer so consumers can take advantage of lower rates at off-peak times. Using a smart-grid technology, a car charger could pick its charge time and rate by communicating through a smart meter.
But what if someone can't charge at home? Like others, utility industry group the Edison Electric Institute advocates new building codes demanding that all new buildings are wired so that charging stations can be added in places such as underground parking garages in apartment buildings or retail areas, according to Anthony Earley, the chairman of the institute and CEO of utility DTE Energy.
A few charging stations will go a long way, according to people who spoke at the conference. "We act like this is a chicken-and-an-egg problem, but it's really not," said Mark Duvall, the director of electric transportation at the Electric Power Research Institute. "They are not enabling technologies, in my opinion, but they can help."
If plug-in electric vehicles are wildly popular with consumers and fleet owners, the industry will then face the challenge of having sufficient capital to scale up. During a discussion on battery technologies, academics said that even now, there isn't a sufficient workforce to do the engineering required for electric vehicles, with the most glaring hole in materials science.
Although higher manufacturing should significantly cut battery prices, there were regular questions about the supply of lithium at the conference. Overall, auto and battery company executives said lithium supply is not a pressing concern. Lithium could be extracted from different sources and can be recycled, said Yet Ming Chiang, the chief scientist of battery upstart A123 Systems and professor of ceramics at the Massachusetts Institute of Technology.
The U.S. auto industry has an opportunity to be reinvigorated with electric auto technologies, as its seeks to transition from the "rust belt to the green belt," Michigan Gov. Jennifer Granholm said Wednesday. China, meanwhile, is investing heavily in electric transportation, which national leaders see as a way to "leapfrog" to the latest technologies, said Yibing Wu, the managing director of Legend Holding, the company that makes Lenovo laptops and is moving into clean energy.
On an environmental level, plug-in hybrid cars have 30 percent lower carbon emissions, even if a car is fueled by coal-fired power plants, Earley said. That's particularly important on a global level, since hundreds of millions of cars are expected to be sold in the coming years in developing countries, said Ann Marie Sastry, a University of Michigan professor and a co-founder of a Khosla Ventures-backed battery company Sakti3.
"The small car is absolutely going to be essential for electrification and to all of us because it doesn't matter where the carbon comes from--whether we generate it or it comes from the emerging economies," Sastry said. "It's imperative (that) the United States play a role in this technology development because of our own interest in climate change."

Just as carmakers develop electric cars, motorcycle manufacturers also see the writing on the wall, showing off a collection of electric bikes at the 2009 Tokyo Motor Show. The Tokyo Motor Show has always played host to a substantial display of motorcycles, and this year is no different--except that the highlights of the show all have a green angle. Honda, Yamaha, and Suzuki all brought concepts to the show that could spell the future of riding, and possibly a new way for future commuters to get to work.
