This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Nissan recalling 841k vehicles overseas for steering wheel trouble

A possible issue with a steering wheel bolt in the Nissan Micra (shown) and Cube from the 2002 to 2006 model years has Nissan recalling roughly 841,000 units on four continents, as well as Oceania and the Middle East. On the affected cars, the bolt may not have been tightened properly, which could lead to a loss of steering in a worst-case scenario. According to Reuters, there haven't been any reports of accidents or injuries due to the fault, however.
The Micras affected were built in the UK and Japan, the Cubes in Japan. Nissan has yet to say when the recall will begin, but when it does, owners can take their cars to dealers for repairs; the bolt with either be tightened or, if necessary, a new steering wheel installed.

Nissan puts Around View Monitor on ocean-exploring robots [w/video]

Capable as it may be, we wouldn't advise driving your crossover to the bottom of the ocean. Nissan, however, is doing the next best thing by putting its Around View Monitor on seabed-crawling robots. The partnership brings Nissan together with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Topy Industries, a leading manufacturer of robotic crawlers. Nissan supplies the Around View Monitor it usually puts in its crossovers and SUVs, which Topy installs on its Remotely Operated Vehicles (ROVs) and JAMSTEC sends to the ocean floor. The project even enjoys support from the Japanese cabinet through its Strategy Innovation Promotion program that aims to bring private-sector innovation to government projects. With Nissan's 360-degree camera technology, JAMSTEC and Topy hope to "uncover the mysteries of the oceans," and seem to be going about it a smarter way than submerging a landlubber like the Juke or Rogue to car-crushing depths. Just what they'll uncover remains to be seen, but we're looking forward to finding out, and applaud the initiative. Of course, Nissan isn't the first automaker to deploy its technologies in robots to explore undiscovered worlds: Toyota recently lent its voice-recognition system to the Kirobo project that put a pint-sized robot in orbit to converse with the astronauts in the International Space Station.

NISSAN AVM TECH TO GO UNDERWATER FOR DEEP SEA EXPLORATION - Nissan's Around View Monitor (AVM) technology will help remotely operated vehicles (ROVs) search for natural resources in the Earth's oceans - Nissan's AVM is building block of company's autonomous drive technology - Featured across Nissan's crossover range including best-selling new Juke, Qashqai and X-Trail Nissan is providing its unique Around View Monitor (AVM) technology to the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Topy Industries, Ltd., through a joint development project that may help uncover the mysteries of the oceans. The joint development contract with JAMSTEC and Topy, one of the top manufacturers of robot crawlers in Japan, will enhance the government agency's ability to search deep underwater for natural resources using remotely operated vehicles (ROVs). Nissan's AVM technology will help ROV operators avoid obstacles and navigate the ocean seafloor more easily.
