Google’s “Pi” In The Face

The Rush To Electric Cars Will Replace Oil Barons With Lithium Dictators
1. Revenge Of The Electric Car
One day in late 2005, after losing yet another bruising political battle to the bean counters inside General Motors, then-vice chairman “Maximum” Bob Lutz heard of a startup called Tesla Motors intending to bring an all-electric sports car to market. Enraged that a bunch of Silicon Valley gearheads could do what he couldn’t, Lutz, in his own words, "just lost it." He rallied his fellow car guys within GM to develop the prototype of what became the Chevrolet Volt--the “moon shot” justifying the company’s survival and the first in a new wave of electric vehicles just beginning to break on dealers’ showrooms. And while the Volt uses just a tiny bit of gas, it's still powered by a material that is in short supply and controlled by some of the most hard to deal with governments in the world. Its lithium battery might just create a new geopolitical calculus that is just as problematic as the gas-based one electric cars are supposed to extricate us from.
2. Peak Lithium?
A month before the Volt announcement, an energy analyst named William Tahil published a paper titled “The Trouble With Lithium.” There simply isn’t enough cheap lithium to go around, he argued, and 80% of the world’s accessible reserves are located in the so-called “Lithium Triangle” of the Chilean, Argentine, and Bolivian Andes (pictured above). “If the world was to exchange oil for Li-ion based battery propulsion,” Tahil wrote, “South America would become the new Middle East. Bolivia would become far more of a focus of world attention than Saudi Arabia ever was.” Even then, we would run out of lithium long before we’d finished electrifying our cars.
Tahil’s paper immediately came under fire for his overly pessimistic predictions. Researchers at the Argonne National Laboratory outside Chicago--a hotbed of lithium battery innovation--estimate worldwide demand will eventually top out at 8 million metric tons, total. (The Volt’s massive battery array only requires about nine pounds.) That’s well within the U.S. Geological Survey’s conservative estimate of 12 million tons of recoverable reserves. As refining improves and new deposits are discovered, that figure will only go up. And unlike oil, lithium can be recycled; once you get it out of the ground, it’s yours.
3. From Petro-Dictators To Electro-Dictators?
Fortunately for GM and Toyota, Chile’s and Argentina’s lithium deposits are open for business. But the largest lies across the border in Bolivia, containing anywhere from 9 million (the official U.S. estimate) to a credulity-straining 100 million tons of lithium. Bolivia’s president Evo Morales (left) is no friend of the U.S., however; he pals around with Venezuela’s Hugo Chavez and Iranian president Mahmoud Ahmadinejad. He once expelled the U.S. ambassador and likes to end speeches with the rallying cry, “Death to the Yankees!”
4. If It's Not Lithium, It's Something Else
There are two alternatives to entrusting the bulk of America’s lithium supply to Chile, Bolivia, or even Afghanistan--discover new sources closer to home, or innovate our way out. In Bottled Lightning, author Seth Fletcher pays a visit to Western Lithium’s stake in the Nevada foothills where it hopes to mine lithium from clay deposits. A spin-off from Lawrence Livermore National Laboratory called Simbol Mining believes it can meet nearly a fifth of the world’s needs by mining California’s (chemical-rich) Salton Sea.
The other option is to treat Li-ion batteries as a bridge technology on the way to something lighter, cheaper, and better. “We need something with the energy density of gasoline,” says LeVine. “We need the new technology--sulfur-air, zinc-air, lithium-air.” Other teams are working on a battery made of molten melts and salts.

Google launches Google+, a quasi-Facebook competitor
NEW YORK (CNNMoney) -- Google on Tuesday unveiled Google+, yet another attempt by the search giant to overcome its past miscues in the social networking space.
More people visit Google's network of websites than Facebook each month, but Facebook is killing the search company in categories that advertisers care most about: Time spent and pages viewed. Users spent 62% more time on Facebook than on Google last month, and viewed more than twice the number of pages on Facebook as they did on Google, according to comScore.
Google's latest solution to this growing trend is Google+, a new social network that tries to out-Facebook Facebook. On Facebook, people are either "friends" or not. Google+ makes that distinction more fluid, letting users group their contacts into smaller categories, such as relatives, co-workers, or members of a yoga class. Information can be shared selectively with each group."The subtlety and substance of real-world interactions are lost in the rigidness of our online tools," said Vic Gundotra, Google's senior vice president of social, in a blog post. "In this basic, human way, online sharing is awkward. Even broken. And we aim to fix it."
Though Google often denies that Facebook is the company's primary competitor, sources with knowledge of the project say that Google+ was known internally as "Googbook." Google devoted 300 people to the team.
Unlike Google's previous social attempts, such Orkut and Buzz -- which had big, bold launches and are largely considered failures -- Google is moving slowly and cautiously with Google+. It has only been launched for a small group of users, and others need to be invited to the service to use it.
