Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.

The List #0025: Compete in the Rallye Aicha des Gazelles

The Rallye Aicha des Gazelles du Maroc is an annual all-women's off road rally in the Moroccan desert. Teams of two must navigate between various checkpoints using only a rudimentary map and compass. Host Jessi Combs pairs with driver Nicole Pitell to take on the grueling, nine-day rally race, as co-host Patrick McIntyre tracks their progress in the desert heat. "The thing that's going to drive me nuts today is that we can't help," Patrick tells Jessi moments before she departs on a two-day marathon leg. "We can do nothing but watch." For Jessi – an experienced off-road racer in her own right – navigating the Sahara in the team's Total Chaos Tacoma is a challenge unlike any other. "You know when you've ever really, truly been lost and you don't know where you are and you start to getting that anxiety feeling? Now, take that and put it into the middle of Morocco," explains Jessi. "And we're just this lost, little spec, and it's our responsibility to get us un-lost and back to safety." How will Jessi fare among the newcomers class and ten US teams in attendance? Watch as she checks "compete in the Rallye Aicha des Gazelles" off of her list. Have an RSS feed?

Toyota still wants Tesla's battery help, still evaluating RAV4 EV program

Tesla Motors said earlier this month that the agreement it has with Toyota to supply battery packs for the Toyota RAV4 EV SUV would be finished by the end of the year. The deal is done, but Toyota is now singing its best version of Baby, Please Don't Go. The Japanese automaker may look to extend the battery-pack agreement with California-based Tesla, Automotive News says, citing comments made by Osamu Nagata, who heads Toyota's manufacturing and engineering in North America. Nagata also complimented Tesla for its "clear business strategy." Toyota, which owns 2.5 percent of Tesla, started the RAV4 EV collaboration in 2012, in which Tesla was to make about 2,600 battery packs for the all-electric SUV. That agreement was estimated to be worth about $100 million. "We are also evaluating the RAV4 EV program and will have more to say at a later date" – Toyota "We have a good relationship with Tesla and will evaluate the feasibility of working together on future projects," Toyota said in a statement e-mailed to AutoblogGreen. "We are also evaluating the RAV4 EV program and will have more to say at a later date." And while Toyota hasn't quite met initial sales expectations – it sold about 1,600 of the RAV4 EVs through this spring – the company expects to reach 2,500 by the end of the year. And the partnership did generate about $15 million in revenue for Tesla, according to that company's first-quarter letter to shareholders. That said, Tesla is obviously focusing its battery-making efforts on its own models.
