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.

Recharge Wrap-up: Comparing Nissan Leaf performance by climate, natural gas iffy for trucks

A new Carnegie Mellon University study looks at the effects of regional climate variations on the Nissan Leaf. The study shows (unsurprisingly) that the ambient temperatures of different regions have effects on battery performance and the use of climate control, both of which affect range. Efficiency and grid mix determine regional differences in emissions per mile. CMU enumerated many of the differences in performance across the US. For instance, on the coldest day of the year, maximum range can be 70 miles on the Pacific Coast, while it is less than 45 miles in the Upper Midwest. These differences in efficiency can also affect adoption patterns. Read more at Green Car Congress. Battery charger manufacturer CTEK has licensed WiTricity wireless charging technology. CTEK looks to commercialize the wireless power transfer tech for use with electric vehicle batteries, making the "plug-in" aspect of EV charging unnecessary. WiTricity's charging technology stands out for its ability for distance charging via magnetic near field. "We are excited to be on the forefront of the next generation of battery charging products for consumers and industry, and look forward to leveraging WiTricity's ground-breaking technology to bring a new level of convenience and ease of use to market," says CTEK CEO Jon Lind. Wireless charging is convenient for the public, but also especially useful for emergency vehicles, which need to be ready at a moment's notice but also keep electrical systems online while the car is parked.

Switching heavy trucking fleets from diesel to natural gas could make economic sense, but the environmental benefits aren't as certain, according to a new study from UC Davis and Rice University. Certain regions - particularly California, the Great Lakes and mid-Atlantic regions - could benefit from the switch with minimal investment. "But to have an environmental advantage for reducing greenhouse gas emissions would take significant policy intervention," says Amy Myers Jaffe, executive director for Energy and Sustainability at UC Davis. This would mean stricter efficiency standards for natural gas trucks, as well as stronger regulations for methane leakage. Read more in the press release from UC Davis below.

2014 Nissan Juke Nismo RS priced from $26,120*

We'll admit, we're quite excited about the Nissan Juke Nismo RS, especially now that its price has been revealed. For $26,120, you can get the sharpest, sportiest Juke outside of the over-caffeinated, 545-horsepower Juke R.
That base price reflects the cost of the Juke Nismo RS you really want - the front-drive model, complete with six-speed manual. Snagging an all-wheel-drive, CVT-equipped version will cost an extra $2,000. Those prices don't include an *$810 destination charge.
The Juke Nismo RS boasts an extra 18 hp and 26 pound-feet of torque over the 197-hp Juke Nismo, thanks to things like a new exhaust. The big, must-have feature, though, are the Recaro thrones fitted in the front of the RS. As we said when the hot Juke debuted in LA last year, the seats alone may be worth upgrading to the RS model.
