SIMDrive Corp announces new inwheel electric car

first_img Citation: SIM-Drive Corp announces new ‘in-wheel’ electric car (2011, April 1) retrieved 18 August 2019 from https://phys.org/news/2011-04-sim-drive-corp-in-wheel-electric-car.html While traditional cars have their motors under the hood, including most EVs, the SIM-LEI, uses small electric motors mounted in the individual wheel housings behind the tires. These motors than drive the wheels directly, rather than using a drive shaft, which makes them far more efficient than other cars. Until now, in-wheel motors have been thought to lack the power necessary to propel a car in a manner that most are used to. SIM-Drive appears to have overcome this problem however, with new technology (including using outer-rotors and inner stators, instead of the traditional inner rotors and outer stators) as the SIM-LEI is able to move from 0 to 62 mph in just 4.8 seconds. And because the individual motors can be fitted with sensors, allowing nearly instantaneous reaction to conditions, responsiveness is expected to be better than most cars now on the road. According to the company, the SIM-LEI is capable of traveling 333 km (207 miles) on a single charge.SIM-Drive engineers also decided to put the batteries and inverters under the floorboards rather than in either trunk, likely because it brings them closer to the in-wheel motors; doing so has the added benefit of allowing far more leg room up front than most are used to with Japanese cars. SIM-Drive Corporation was formed in 2009 with the intent of pushing forward new technologies in the electric car market. The consortium is affiliated with Keio University and the SIM-LEI will likely be marketed through consortium members, Mitsubishi and Isuzu. No price has yet been set, though a target date of 2013 has been listed as the time frame for “commercialization” of the vehicle.Finally, SIM-Drive, in its communiqués, has made it clear to the Japanese public that the vehicle, if successful, shouldn’t add any new additional stress on electricity demands (currently an issue with the rolling blackouts due to the Fukushima power plant problems) as its batteries can be charged at night when demand is low. Explore further Named, the SIM-LEI, (Leading Efficiency In-Wheel motor), the electric vehicle (EV) is roughly the same length as a sedan but only as wide as a compact. It sports the same lithium-ion batteries (supplied by Toyota Corp) as most other EVs on the market and can travel over two hundred miles on a charge. What’s unique about the SIM-LEI though, of course are the in-line electric wheels. (PhysOrg.com) — SIM-Drive Corporation, a Japanese consortium based in Kawasaki-shi and comprised of 34 companies and municipalities, has announced that it has developed a functioning electric car based on in-wheel electric motor technology.

US energy use chart shows we waste more than half of our

first_imgThis flow chart shows the amount of energy (in quads) that is produced by different energy sources and consumed by different sectors. Image credit: Lawrence Livermore National Laboratory and the US Department of Energy. Citation: US energy use chart shows we waste more than half of our energy (2011, April 9) retrieved 18 August 2019 from https://phys.org/news/2011-04-energy_1.html (PhysOrg.com) — This flow chart of the estimated US energy use in 2009, assembled by the Lawrence Livermore National Laboratory (LLNL), paints a pretty sobering picture of our energy situation. To begin with, it shows that more than half (58%) of the total energy produced in the US is wasted due to inefficiencies, such as waste heat from power plants, vehicles, and light bulbs. In other words, the US has an energy efficiency of 42%. And, despite the numerous reports of progress in solar, wind, and geothermal energy, those three energy sources combined provide just 1.2% of our total energy production. The vast majority of our energy still comes from petroleum (37%), natural gas (25%), and coal (21%). That percentage of oil illustrates that by far our biggest problem – or area of improvement – is transportation. As the chart shows, the transportation sector is the single biggest consumer of energy, accounting for nearly 40% of the energy consumed by the four sectors (along with residential, commercial, and industrial). In comparison, just 16% is used for residential use. And while the residential, commercial, and industrial sectors waste about 20% of their energy, the transportation sector wastes a full 75%, making it just 25% energy-efficient. Part of this waste is due to the fact that cars are an inherently inefficient way to move people around, since much of the energy must go into moving the massive car and not simply the person.The chart emphasizes the importance of using alternative methods of transportation – walking, biking, public transportation, or anything else that moves more human and less steel. Unfortunately, due to developers building sprawling suburbs to satisfy Americans’ demands of large homes and yards, many people now find themselves miles from the nearest grocery store and have no choice but to drive everywhere. To illustrate how transportation consumption and waste dwarfs residential consumption, a blog post on Treehugger notes that “building suburbs of Energy Star houses with solar panels on top is a complete waste of time.”With that being said, comparing the 2009 chart to the 2008 chart shows that we’re making progress. The total amount of solar energy production increased from 0.09 to 0.11 quads, wind energy increased from 0.51 to 0.70 quads, and geothermal increased from 0.35 to 0.37 quads. (The amount of energy in one quad is equivalent to that produced by the burning of 36 million tonnes of coal.) Overall, the US consumed less total energy in 2009 (94.6 quads) than in 2008 (99.2 quads) as well as any year back to 1999 (97 quads), which is the first year for which LLNL has a chart on its website. There were even three years during the past decade when the country consumed more than 100 quads. In addition, the total waste in 2008 was 57.07 quads, compared to 54.64 quads in 2009 (though the percentage wasted was about the same).Although there is vast room for improvement, if the US can employ a combination of decreasing consumption, increasing efficiency, and increasing the role of renewable energy sources, hopefully we’ll continue heading in the right direction.

Credit: Danielle Dufault © Royal Ontario Museum Meet Zuul crurivastator, a new armoured dinosaur! Zuul’s skeleton is one of the most complete ever found for an ankylosaur, and has an amazingly preserved spiky tail and tail club. The researchers report that the dinosaur met its fate in a body of water of some sort and was quickly covered in sediment, which acted as a very good preservation material. In addition to bones, the team was also able to make out the remains of soft tissue which, included spike sheaths and scales. The sediment also helped keep the specimen together in its original configuration, offering an unprecedented representation of how the creature looked while still alive. The team also notes that they are hoping that further study of the remains will help fill in gaps in the ankylosaurs record.

Credit: Brian Boyle © Royal Ontario Museum The researchers report that they were actually in the process of digging up another fossil that had been identified when they came across an ankylosaur tail. After excavation, the specimen was found to be approximately 20 feet long, and the team has estimated it would have weighed approximately 5,500 pounds, making it approximately the size of a modern white rhinoceros. It has been dated to approximately 75 million years ago, putting it in the Campanian Stage of the Late Cretaceous Period.As with others of its kind, the specimen had a long, spiked tail that was clearly designed for striking enemies, but not prey— ankylosaur was a vegetarian. It also had a spiky head, which looks, depending on your view, either like a dragon or Zuul, the supernatural demigod depicted in the movie Ghostbusters. Because of that, the specimen has been officially named Zuul crurivastator—the second part of its name in rough translation means “destroyer of shins,” a nod to its 6.7 foot, 13-vertebra-spiked tail, which also featured a knob or hammer-like end.

JSPL suspends work at Australias oldest coal mine

first_imgJindal Steel and Power Ltd (JSPL) on Tuesday said it is suspending work at the Australia’s oldest coal mine, Russell Vale Colliery, due to “significant financial losses” and “operational difficulties”.JSPL-controlled Wollongong Coal Limited (WLC) owns and operates Russell Vale Colliery and Wongawilli Colliery in the Southern Coalfields region of New South Wales in Australia. “Mining operations at the Russell Vale Colliery will be suspended and placed into ‘Care and Maintenance’, which will result in a reduction of the workforce by approximately 80 employees,” WLC said in a regulatory disclosure. When contacted, a JSPL spokesperson said, “Work force restructuring and rationalisation of man power has been undertaken at WCL, keeping in mind the present and emerging work load requirements.” Also Read – Punjab & Sind Bank cuts MCLR by up to 20 basis pointsThe acquisition of WCL is strategic to the Jindal Group in fulfilling its metallurgical coal (coke) requirements and the group remains optimistic about commencement of operations in the colliery in the near future, she added. “WCL is confident of obtaining the requisite approvals for longwall extraction in the Russel Valle Colliery and would soon commence operations,” the spokesperson said.JSPL acquired a major controlling stake and management control of WCL in 2013 and has invested over $400 million in the mine in the last two years. On the decision to suspend work, WLC chief Executive Milind Oza said: “This decision is not taken lightly and we have continually attempted to avoid this unfortunate situation by undertaking a series of workforce restructuring.” With partial extraction of longwall 6 at the 128-year-old Russell Vale Colliery complete and the firm experiencing significant losses, ongoing operations at the Colliery are simply not sustainable at this point in time, he added. Also Read – ‘The great gold bull market has begun’Oza said the firm continually attempted to avoid suspending work at the mine, which started operations in 1887, by undertaking a series of workforce restructuring. “Wollongong Coal has been facing a tough operating environment for some time including ongoing delays in the approval of the company’s Underground Expansion Project (UEP) and significant financial losses,” Oza said. According to reports, the closure of the mine has come amid the company’s failure to gain approval for expanding underground mining operations by state’s controversial Planning Assessment Commission in April.  WCL reported a loss of $199.2 million in the financial year to March 31, following $169.4 million loss in the previous year, media reports said.last_img read more
