Recharge Wrap-up: Nissan, Tesla report CO2 savings, rare earth metal recycling simplified

A new process simplifies the recycling of rare earth metals. While the strong magnetic properties of metals like neodymium and dysprosium make them useful in electric vehicles traction motors, there are concerns about their availability and the environmental costs of mining them. Researchers at University of Pennsylvania have developed an easier method to recycle those metals that is less energy intensive and more cost effective. "We have designed a way to separate the two metals by selectively dissolving the neodymium in a solution and leaving behind the dysprosium as a solid," says Justin Bogart, a graduate student working on the project. "This quick and easy method has allowed us to separate equal mixtures of the metals into samples that are 95 percent pure." Now the team is working to improve that level of purity.

Worldwide, the 178,074 Leafs sold account for the prevention of over 293,000 tons of CO2 emissions so far. That equates that to the neutralizing effect of 19 million trees. Besides the positive effects on environmental and noise pollution that switching to electric mobility provides, Nissan also points out that it's good business, too. EVs like the Nissan Leaf and e-NV200 cost about 40 percent less than combustion vehicles to maintain, and the cost of electricity is substantially lower than that of fossil fuels. Additionally, Nissan has published a video of the Leaf touring Bristol to celebrate the greening of European cities with the help of electric vehicles. See the video, and read more from Nissan. Tesla customers have driven a cumulative 1 billion miles. Together, nearly 75,000 Model S drivers have prevented more than 570,000 tons of CO2 emissions worldwide. To put that in perspective, a billion miles is the equivalent of 4,186 trips to the moon, and almost 40,000 trips around the Earth. In the UK, where the Model S is celebrating its one-year anniversary, drivers have already accumulated 6.6 million miles. Tesla is celebrating its milestone with the Next Billion Miles Tour, hosting hands-on events and test drives in 80 cities across North America, Europe and Asia.

Tesla Investigating Fiery Model S Crash In Los Angeles

Automobiles can be dangerous objects, especially when moving at highway speeds. The July 4th holiday in the US, which took place this past weekend, is often an extra-dangerous time on America's roads, with an average of 127 deaths from car crashes in recent years. This year, there were at least two Tesla Model S crashes over the holiday, and despite a spectacular fire in one of the incidents, both of the drivers survived the incidents. "We absolutely want to have a look to understand what happened." – Tesla spokesman Simon Sproule The most dramatic crash happened when a Model S was apparently stolen and taken for a joy ride. Tesla told Bloomberg that the company is eager to take a closer look at what's left of the crashed vehicle, which snapped in half. "There aren't so many S's involved in major crashes, and certainly not quite like this one, so we absolutely want to have a look to understand what happened," said Tesla spokesman Simon Sproule. Tesla spokesperson Liz Jarvis-Shean told AutoblogGreen that, "We're working with relevant authorities and will be examining the car as we would with any accident." What isn't yet clear is how the reported thief was able to drive the stolen Model S (Tesla has not yet responded to our questions on this front). Media reports say it was someone at the Tesla store who reported the theft to police as it was happening, so it would seem that Tesla knew about the incident well before the crash. Whether there enough time to tell the police where the car was going or to deactivate the car is unknown. In another tragic crash that happened this weekend, a Model S rear ended a Toyota Corolla. Three of the occupants of the Toyota were killed but the Tesla driver only suffered "minor injuries," according to the Los Angeles Times. The Model S received five stars in the NHTSA's crash tests and has had safety improvements since those tests were conducted. Previous Tesla's have caught fire but no serious injuries have been reported.

Superchargers power Tesla Model S EVs for over 8M miles [UPDATE]

Ahead of the company's press conference at the Detroit Auto Show tomorrow, Tesla is talking up its Supercharger network with some impressive numbers. Tesla's Alexis Georgeson told AutoblogGreen that Tesla Model S EVs have driven more than eight million miles on Supercharger fill-ups. That's the equivalent of 33-and-a-half trips to the moon and back. We can see how quickly the free Superchargers are getting popular by comparing this milestone to where we were four short months ago. At the end of September, after the Superchargers had been installed for a year, Tesla drivers had hit 3.2 million miles. The rapid increase since then is due mostly to there simply being a lot more chargers being available now. Tesla representatives told us that there are over 70 Supercharger stations in the world today (58 in North America and 14 in Europe) and that six were installed in the past week. Georgeson didn't have numbers on hand to say which stations were the most popular or other details, but did say that it's safe to assume that the Supercharger in Lusk, WY (pictured), part of a sweeping 'S' shape from Los Angeles through the northern US and on to Chicago and the East Coast, is not the most frequently visited. The next target for expansion is finishing the Boston-to-Miami corridor, which means putting in more Superchargers in North Florida and South Carolina. At CES last week, the Supercharger network won our AOL Technology of the Year award. *UPDATE: Tesla just let us know that 8 million is a little premature. The current number is actually closer to 7.5 million, but the total should crest the 8-million mark soon.
