Superconductor electric vehicle

12 Jun 2008

Car powered by superconductor motor --

Sumitomo Electric has developed what is being called the world's first automobile powered by a superconducting motor. The electric passenger sedan (a modified Toyota Crown Comfort), which is powered by a high-temperature superconducting motor cooled by liquid nitrogen, was unveiled in Osaka on June 12 and will go on display at the Hokkaido Toyako G8 Summit on June 19.

Superconductors -- energy-efficient materials that can carry electrical current without resistance -- are used in applications ranging from medical devices to linear motors for trains. Until now, however, they have never been used to power an automobile, says Sumitomo, who developed an ultra-powerful 365-kw superconducting motor last year.

Superconductor motor used to power car -- Sumitomo's motor uses high-temperature superconducting wires instead of the copper wire typically used in the coils in electric vehicle motors. When cooled to -200 degrees Celsius, electrical resistance and current loss are reduced to nearly zero, so the motor can operate with greater energy efficiency and torque -- in other words, the motor uses less electricity to do the same amount of work. The company says the prototype vehicle can travel more than 10% farther than conventional electric vehicles running on the same type of battery.

The development comes as demand for electric vehicles grows, and as manufacturers step up efforts to improve battery and motor performance to increase the distance that vehicles can travel on a single charge.

Sumitomo intends to further improve the motor with the aim of putting a vehicle on the market in the not-too-distant future. The company is looking to develop superconductor motors for buses and trucks as well.

‘Tondon’: Balinese-style robot janitor

02 Aug 2007

Tondon, robot janitor --- An autonomous robot janitor built by Subaru (Fuji Heavy Industries) and Sumitomo has landed a job cleaning the outdoor hallways of a new 14-story Bali-themed luxury apartment complex in Tokyo. Lovingly nicknamed 'Tondon' in an apparent reference to a legendary Balinese snake god, the robot is a close relative of RFS1, the autonomous floor cleaning robot that received Japan's 2006 Robot of the Year Award last December.

Like the RFS1, which currently cleans hallway floors inside ten Tokyo-area office buildings, Tondon works unsupervised and relies on an optical communication system to control the building's elevators, allowing it to move freely from floor to floor as needed. To improve the robot's ability to clean gritty outdoor surfaces, Tondon's makers have added a set of heavy-duty brushes designed to sweep up leaves and dirt from hallway floors and drains. Furthermore, Tondon's outer shell has been strengthened and waterproofed to protect its internal components from the elements, and it has been painted with a unique design to complement the apartment building's Bali-themed decor.

Tondon also has a number of safety features that help it better coexist with the building's residents, including proximity sensors that help prevent collisions with people, as well as bumper switches that stop the robot in its tracks when it is touched. A protective guard around the brushes prevents the robot from giving people unwanted shoeshines, while lamps and voice announcements provide ample warning when it is approaching.

A set of video cameras has also been added to the robot. With four cameras that record the robot's every move and a hard disk that stores the video feed, human overlords can keep close tabs on Tondon to make sure it doesn't nap on the job. The cameras can also be used for hallway surveillance, the company says, allowing the robot to double as a watchful security guard as it cleans.

Seaweed as biofuel

23 Mar 2007

Sargasso seaweed as biofuel --- On March 22, a group of Japanese scientists released details of an ambitious proposal calling for the large-scale production of bioethanol made from cultivated seaweed.

Researchers from Tokyo University of Marine Science and Technology, Mitsubishi Research Institute, Mitsubishi Heavy Industries and several other private-sector firms envision a 10,000 square kilometer (3,860 square mile) seaweed farm at Yamatotai, a shallow fishing area in the middle of the Sea of Japan. They claim a farm of this scale could produce about 20 million kiloliters (5.3 billion gallons) of bioethanol per year, which is equivalent to one-third the 60 million kiloliters (16 billion gallons) of gasoline that Japan consumes each year.

Seaweed has long been discussed as a potential source of bioethanol, which is typically made from crops such as sugar cane and corn, but the idea has never been brought to fruition. According to the proposal, giant nets used in nori and wakame seaweed cultivation would be laid out to cultivate sargasso seaweed (hondawara), which grows rapidly. Floating bioreactors -- special facilities that use enzymes to break the seaweed down into sugars -- would prepare the seaweed for conversion into ethanol, which would also be done at sea. Tankers would then transport the ethanol to land.

The main components of seaweed are fucoidan and alginic acid. While an enzyme for breaking down fucoidan has already been discovered, the scientists are looking for an enzyme that breaks down alginic acid. They are also looking at the possibility of using genetic modification technology.

The group is also conducting research on how to develop the production plants and attract investment. Other participants in the project include NEC Toshiba Space Systems, Mitsubishi Electric, IHI, Sumitomo Electric Industries, Shimizu Corporation, Toa Corporation, Kanto Natural Gas Development Co., Ltd., and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC).

The researchers claim that in addition to serving as a source of fuel, the seaweed would help clean up the Sea of Japan. According to Professor Masahiro Notoya from Tokyo University of Marine Science and Technology, the seaweed would work to remove some of the excess nutrient salts that flow into the sea from the surrounding land masses.

Professor Notoya will formally present the proposal at the International Seaweed Symposium, which is set to begin on March 26 in Kobe, Japan.

Cyber-concrete lets walls speak

15 Dec 2006

YRP Ubiquitous Networking Laboratory -- Sumitomo Osaka Cement and YRP Ubiquitous Networking Laboratory have developed cyber-concrete, a smart form of concrete embedded with RFID tags that can store data. Researchers developed a durable coating for YRP's "ucode" tags, which have a larger storage capacity than ordinary IC tags, and they developed a special reader that, when held near the concrete, retrieves the stored data and converts it into spoken form.

Sumitomo is set to begin field testing the technology at its cement factories this month, with the aim of making it available to large construction companies in the spring of 2007.

While the potential applications of cyber-concrete are endless, the companies are initially promoting it as a new tool for managing structural safety data. Cyber-concrete can store information about itself, such as when, where and how it was manufactured and data about strength and quality, making for more efficient and reliable safety inspection systems. This traceability data can be used by construction companies, inspectors, or tenants concerned about building safety.

Public concern for structural safety has risen with a recent building safety inspection scandal involving the discovery of falsified quake-resistance data for a number of buildings in Tokyo and the surrounding areas. Perhaps cyber-concrete will bring a little peace of mind, allowing people to bypass the shady inspectors and ask buildings directly how safe they are -- which is great as long as buildings have no reason to be dishonest.

And should you find yourself trapped under three floors of cyber-concrete after the Big One, at least you'll have something to talk to while waiting for the rescue bots to arrive.

Pimp my Dream Tanker

05 Sep 2006

Dream Tanker

The Dream Tanker, one of the largest liquified natural gas (LNG) tankers in the world, now travels in style. Comedian-turned-painter Jimmy Onishi and 40 elementary school students have designed monster-sized psychedelic murals for the ship's spherical tanks. The total area covered by the murals is large enough to cover 100 buses.

The 120,000-ton Dream Tanker, owned by an affiliate of Osaka Gas, measures 289.5 meters (950 feet) long and 49 meters (160 feet) wide. With 4 independent spherical tanks measuring 43 meters (140 feet) in diameter, the tanker can hold up to 67,000 tons of LNG.

Osaka Gas decided to decorate the tanker with graphics in celebration of the company's 100th anniversary. The company asked Kansai-area elementary school students to draw pictures, which Jimmy Onishi then incorporated into his giant images of a fish, crab, shrimp and turtle. Sumitomo 3M Ltd. then used computers to process the images and printed them onto a special adhesive film, which was attached to the tanks.

The total surface area of the images amounts to about 4,000 square meters (43,000 square feet, or 1 acre), prompting Sumitomo 3M to submit an application to the Guinness Book of World Records to officially establish the work as the world's largest graphic design on a mode of transportation.
