Tesla gigafactory will source materials from North America to keep things green

It's one thing for the Big 3 to get tires and engine parts from cities along the US Rust Belt. It's another thing altogether, though, for Tesla Motors to source far more esoteric materials like graphite, cobalt and lithium from Canada and the northern US. But that's what the California-based company has in mind, and it's all in the name of environmental friendliness and cost, Bloomberg News says. Tesla is looking to bring its raw-material sourcing to this side of the Pond by the time it opens its massive gigafactory that may produce as many as 500,000 vehicles annually, Bloomberg says, citing Tesla spokeswoman Liz Jarvis-Shean. And while the raw-material price may be higher (and driven up further with the additional demand from Tesla), those costs may be offset by the fact that there will be far less transportation and logistics involved. "When all costs are considered, it should be cheaper to source most materials from as nearby as possible" - Tesla's Liz Jarvis-Shean "Transportation impacts are very significant on the heaviest raw materials if they need to be moved from halfway around the world," Jarvis-Shean wrote in an e-mail to AutoblogGreen, adding that there will be additional cost savings from reduced shipping time and less transit-related working capital requirements. "In the long term, when all costs are considered, it should be cheaper to source most materials from as nearby as possible." There are geopolitical issues as well. For instance, China is shutting down some of its graphite mines because of pollution issues, while much of the world's cobalt comes from war-torn Congo, though Tesla says it gets its cobalt from the Philippines. Most of the graphite in Tesla's Model S is of the synthetic variety from Japan and Europe. Of course, Tesla's still trying to figure out where to put its gigafactory, and has said it will be in one of four states: Arizona, Nevada, New Mexico or Texas. The factory will cost an estimated $5 billion and may support 6,500 jobs, so state governments are already starting to campaign to be the automaker's future production home. Regardless, Jarvis-Shean estimated that the sheer economies of scale from the gigafactory will reduce battery-pack costs per kilowatt hour for the company's "mass market" model (sometimes referred to as the Model E) by 30 percent after a full year of production.

Tesla adds free titanium underbody shields to Model S to prevent fires

Following a garage fire incident with a Model S EV last year, Tesla Motors quickly sent out an over-the-air software update to adjust how the car charges. Following two on-road fires caused by road debris that struck the underside of different Model S EVs (one in Washington State and the other in Tennessee), Tesla basically said, that it was a random thing, and the car is perfectly safe. The company later sent out a software update to have the car ride a bit higher at highway speeds. Today, Tesla is offering a more substantial solution. Tesla CEO Elon Musk has announced that all Model S EVs built since March 6 have a stronger triple underbody shield that should "bring this [fire] risk down to virtually zero." The company conducted 152 tests using, "every worst case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event, essentially equivalent to driving a car at highway speed into a steel spear braced on the tarmac" and is now confident that there's basically nothing that can break through the new barriers. As you can see here, the shields prevent a concrete block, a three ball tow hitch and a steel alternator from puncturing the car's underside. The new shields should "bring this [fire] risk down to virtually zero." Any Model S owner who wants the new triple shield can ask for it, and even if they don't ask, the structure will be installed whenever the car is next in for service. The three layers of the shield include a rounded, hollow aluminum bar, a titanium plate and "a shallow angle, solid aluminum extrusion." The new shields, "only have a 0.1 percent impact on range and don't affect ride or handling," Musk writes, which means there's no reason for Model S owners not to get the upgrade. You can read all of Musk's explanation below. Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S By Elon Musk, Chairman, Product Architect & CEO In 2013, two extremely unusual Model S collisions resulted in underbody damage that led to car fires. These incidents, unfortunately, received more national headlines than the other 200,000 gasoline car fires that happened last year in North America alone. In both cases, the occupants walked away unharmed, thanks to the car's safety features. The onboard computer warned the occupants to exit the vehicles, which they did well before any fire was noticeable.

Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.
