Masakatsu Sashie’s fantastic “orb” paintings depict large, city-like spheres that float gently above the remains of a failed civilization. The giant orbs, which seem to be self-contained worlds unto themselves, are pieced together from the scraps of old Showa-period buildings and bits of consumer culture, such as vending machines, pachinko parlors, fast food signs, and video game components. Part retro and part sci-fi, the orbs appear to hover gracefully between the worlds of a nostalgic past and a dystopian future.

As part of the upcoming Aqua Metropolis festival in Osaka, engineering firm NTT Facilities has developed a pair of solar-powered, UFO-shaped floating water purifiers that will be deployed in the city’s canals and in the moat at Osaka Castle.

The disc-shaped machines — called “Solar UFOs” — weigh about 3.4 tons each and measure 1.6 meters (5 ft) tall and 5 meters (16 ft) across. During the day, an array of solar panels power the machine’s filtration system, which pumps fresh oxygen into the water while removing impurities. At night, a 1.3-kilowatt solar battery provides juice to the LED lamps lining the edges of the floating craft.

The machines, which can purify about 9,000 liters (2,400 gallons) of water per day, spray the clean water out through a nozzle on top, like a fountain. In addition to keeping the surface clean of bird droppings and grime, the water spray keeps the solar panels cool, helping to maintain a high output efficiency.

The Solar UFOs are built using technology developed by NTT Facilities, a Tokyo-based company (part of the NTT Group) whose business includes architecture, construction planning, power supply system design, and the management of large-scale solar power plants. The water cleaners are currently not for sale.

Plans are to keep one Solar UFO operating in the Dotonbori canal (in central Osaka) until mid-October. The one in Osaka Castle moat is scheduled to remain in operation until the end of March 2010. NTT Facilities also announced plans to deploy Solar UFOs in Tokyo-area waters in the near future.

- Mazda Motonari RX

Mazda Motonari RX [+]

In Mazda’s vision of the late 2050s, advances in molecular engineering have rendered metal-based manufacturing obsolete. The rise of ubiquitous computing and artificial intelligence drastically accelerates the automotive production cycle. Cars are cheap, lightweight (around 200 lbs, or less than 100 kg), and equipped with intelligent crash avoidance systems that eliminate traffic accidents. However, people still manage to get speeding tickets.

[+]

The Mazda Motonari RX — which takes its name from the legendary Japanese warrior Mori Motonari — interfaces seamlessly with the driver to function as an extension of the body.

The vehicle drives sort of like a street luge. Acceleration and direction is determined by two armrest mounted control points, and the vehicle’s exoskeletal frame shape-shifts in accordance with the position of the driver’s arms and legs when enveloped in the seat.

Omni wheels

Four omnidirectional wheels allow 360 degrees of movement, and the tread expands or contracts to suit the driving conditions.

[+]

A “haptic skin” suit consisting of millions of microscopic actuators enables the driver to experience the road psycho-somatically while receiving electrical muscle stimulation from the onboard AI guidance system (or other remotely located drivers).

[+]

The vehicle’s entire structure is comprised of a 100% reprototypable, carbon nanotube/shape memory alloy weave with a photovoltaic coating, which allows the vehicle to mimic the driver’s body movements while powering the in-wheel electrostatic motors. [More]

- Toyota Biomobile Mecha

In Toyota’s vision of the late 2050s, cities have developed vertically due to limited area on the ground, leading the transportation industry to develop new vehicles capable of navigating vertical space.

Toyota Biomobile Mecha [+]

Toyota’s Biomobile Mecha, a shape-shifting vehicle with nano-laser wheels, can read and adapt to changes in the environment and travel vertical pathways by means of biomimetic feet with powerful suction.

[+]

In addition, the Biomobile Mecha is powered by pollution. A special skin derives energy from harmful substances in the air, so the vehicle never runs out of fuel (as long as the future skies remain polluted) and restores balance to the environment while it goes.

[+]

The real-time strategic navigation planning system, which reads the environment via a 3D scanner, gives the vehicle “instincts” that enable it to autonomously adapt to the driving environment.

[+]

Advanced nanotechnology enables the vehicle to expand and contract its structure horizontally and vertically as needed, allowing it to serve as a compact commuter, an aerodynamic performance vehicle, or even as a temporary dwelling. [More]

- Nissan OneOne

In Nissan’s vision of the 2050s, robots have become an integral part of our lives, blurring the line between humans and machines. The Nissan OneOne combines personal mobility with the family robot concept.

[+]

Billed as the ultimate pet, the Nissan OneOne (pronounced “wan-wan,” the Japanese sound for a barking dog) is a friendly, helpful member of the family of the future. Able to operate autonomously without a driver, the GPS-guided vehicle can help out by picking up the dry cleaning, fetching the groceries, and taking the kids to school.

[+]

OneOne propels itself forward by flexing and relaxing synthetic polymer muscles in its “legs,” much as you would if skating on roller blades.

[+]

The vehicle can also assume various positions depending on the driving environment. It reclines to achieve greater speed, and it stands up to increase visibility and squeeze into tight spaces. [More]

- Honda 124 (One to the Power of Four)

In Honda’s vision of the 2050s, people have flocked back to the suburbs, fueling consumer demand for a truly flexible commuter vehicle.

Honda 124 [+]

The solar-hybrid powered Honda 124 (One to the Power of Four) is an energy-efficient, modular vehicle that can separate into four different fully functional units, each uniquely suited for specific driving conditions.

[+]

A combination of robotics, artificial intelligence and molecular engineering (which enables the body panels to be reshaped according to use) allow each module to instinctively reconfigure itself and operate as a fully functional unit. Two of the modules are suitable for short-distance inner-city driving, while the other two are ideal for longer distances at higher speeds.

[+]

Because the Honda 124 consists of multiple units that can be joined together, carpoolers can take advantage of HOV lanes and share commuting costs. [More]

A new online service developed by electronics giant NEC offers carbon-conscious households a fun and friendly way to keep tabs on their energy consumption, as well as that of their neighbors.

Developed in conjunction with major Internet provider BIGLOBE, the service — called “Carbon Diet” — includes an easy-to-install wifi-enabled device that attaches to the home circuit breaker and measures power consumption via electric current sensors. The collected data is then periodically transferred to the home computer using a ZigBee wireless link and sent to an online server for processing.

Users can log on to the Carbon Diet website to check their daily and hourly energy consumption and see how they rank in comparison with other participating households. Users can also see how their monthly carbon footprint compares with the same month of the previous year. Based on the degree to which users actually reduce their carbon emissions, they are awarded “eco-points” that can be exchanged for virtual soil, water, flowers and grass in a nature restoration simulation game.

Participants can also view their progress in the form of a game called “Carbon Ball,” which features dung beetle avatars in a “carbon ball” rolling contest. The distance each household’s dung beetle travels is based on how successful they are in reducing power consumption. The game is designed to instill a sense of competition to keep users motivated and focused on reducing energy consumption.

For now, the three-month trial service is being conducted in the homes of 100 NEC employees. After the trial, NEC and BIGLOBE will work with Ex Corporation (an urban and environmental planning and consulting firm) to analyze the data and develop business models for local governments and the private sector. The company is aiming for sales of 2 billion yen ($20 million) over the next 3 years.

In his “Blast” series of photographs, Naoya Hatakeyama uses remote-control cameras to capture the drama and destruction of Japan’s limestone blasting operations from point-blank range.

The dangerous, close-up views of exploding debris inspire the viewer to consider the human capacity for destruction, while providing a unique perspective on the instant obliteration of these ancient rock formations.

Hatakeyama began photographing Japan’s limestone mining operations in the early 1980s. In 1994, he published Lime Works, a photo book focused on limestone processing facilities.

In 1995, he turned his camera toward the detonation side of the mining process, which he has been photographing ever since.

Limestone, a sedimentary rock consisting mainly of calcium carbonate (CaCO3), is one of the few natural resources in which Japan is totally self-sufficient.

It can be argued that Japan’s (and the world’s) entire way of life is dependent on limestone, a key ingredient in the production of concrete, steel, glass, plastic, and even medicine.

Japan extracts about 200 million tons of limestone from quarries each year, scarring countless mountainsides in the process.

The nation is believed to have an additional 10 billion tons of limestone deposits at its disposal — enough to last another 50 years at the current rate of consumption.

A sewage plant in Japan’s Nagano prefecture has started mining gold from sludge, earning a cool 5 million yen ($56,000) in its first month of operation.

On January 28, sewage plant operator Nagano Prefecture Suwa Construction Office announced that approximately 1.9 kilograms (4.2 lbs) of gold can be mined from each ton of molten fly ash generated when incinerating sludge at its facility in the town of Suwa.

Located in central Nagano prefecture, the Suwa Basin is home to numerous precision machining companies, metal plating facilities and hot springs, which may explain the high concentration of gold in the wastewater sludge.

Joint research conducted in 2007 by Nagano prefecture and the Japan Sewage Works Agency found that the concentration of gold in the ash was comparable to that of a high-grade ore. But because the cost of extracting the gold outweighed the potential profit, the operator continued treating the ash as an industrial waste material.

However, with the recent rise in the price of gold, Suwa decided to start mining the molten fly ash. Last October, they sold 1.4 tons of the ash to a smelting company. At the end of January, Suwa is scheduled to receive its first payment of 5 million yen ($56,000) for the recovered gold.

By the end of March 2009, Suwa plans to mine a total of 5 tons of ash for a profit of 15 million yen ($167,000). The sewage operator says it will use the revenue to help pay for plant maintenance and operating costs.

The facility treats about 100,000 tons of wastewater each day, generating about 3 tons of ash in the process.

The Amami rabbit — a threatened species found only in the Ry?ky? Islands — may become Japan’s first endangered animal clone. Scientists at Osaka’s Kinki University have cloned an embryo of the endangered rabbit and are awaiting its birth next month, it was announced earlier this week.

The Amami rabbit (Pentalagus furnessi) is a nocturnal, forest-dwelling “primitive” rabbit with dark fur, short legs, large curved claws and small ears. Found only on the islands of Amami-?shima and Toku-no-Shima, it is sometimes called a “living fossil” for its resemblance to ancient rabbits that once inhabited the Asian mainland. The Amami rabbit’s dwindling population — now estimated at between 2,000 and 5,000 — has earned it a spot on Japan’s endangered species list.

To produce the clone, researchers took a cell from the ear of a dead Amami rabbit and injected it into the unfertilized egg of an ordinary lab rabbit. After the egg developed into the cloned embryo, researchers inserted it into the oviduct of a lab rabbit surrogate. The clone will be born in the coming weeks if the pregnancy comes to term. The chances of success are slim, though, as cloning pregnancies typically have a high failure rate. However, the scientists are prepared to repeat the process until a clone is born.

Although some people see cloning as a promising tool for restoring endangered populations when natural breeding is not possible, others argue it is more important to address the actual causes of the population decline. Deforestation and road accidents are major reason for the Amami rabbit’s decline, as is the predatory mongoose, which humans released on the islands to control the snake population.

Pet dogs and cats also pose a danger to the species. In June, motion-sensitive cameras set up to monitor Amami rabbit activity on the island of Amami-?shima captured the image of a feral domestic cat dragging a freshly killed carcass through the forest.

If the experiment succeeds, the Amami rabbit will join a growing list of endangered animals that have been cloned. Previous examples include the Asian gaur (a rare ox native to India and Burma), which died two days after it was born in the US in 2001, as well as the European mouflon (a Mediterranean wild sheep) and the Junqueira cow (Brazil).

Regardless of the outcome, the researchers suggest a degree of caution. Although cloning may potentially be used to preserve rare species, little is known about the long-term environmental impact, they said.

In the video, Groovisions use their hallmark playful-yet-ordered sim-like virtual landscape to illustrate a host of food-related challenges facing Japan. Issues include Japan’s 40% food self-sufficiency rate (the lowest of any major industrialized nation), the declining agricultural industry, and the impact of world population growth and environmental changes on the global food supply.

The video also suggests that the Western-style diet of meat, fat and oil, which has partially replaced Japan’s traditional diet of rice, fish and vegetables, has contributed to a variety of health problems and reduced demand for domestically grown produce. The food situation is exacerbated by other demographic factors such as the aging farming population and the abandonment of agricultural land. To reverse these trends, MAFF encourages consumers to make sustainable food choices and urges the industry to produce safe, properly labeled food.

The video (w/ English subtitles) was posted on the official MAFF YouTube channel, which was created last month.

Meet Rabbit-kun, a plastic trash sack with pink eyes, an X-shaped mouth, and a pair of bunny ears that double as handles. Designed by Tokyo-based creative group MAQ, Inc., Rabbit-kun aims to inspire a more responsible attitude toward waste by providing a cute and stylish way for people to carry their trash home after a day outdoors. Whether it’s a picnic in the park, a hike in the mountains, or a day at the beach — or any place without public trash cans — Rabbit-kun is charming enough that you might actually enjoy carting your garbage all the way home.

The bunny-shaped sack is the latest in a line of eye-pleasing Garbage Bag Art Work trash bags by MAQ. Their previous creations include a series of color-coded bags imprinted with patterns of trees, fish and flowers, which are designed to add convenience and character to neighborhood garbage collection points.

Another bag, which features a life-sized illustration (by Lily Franky) of trash-loving Oscar the Grouch, was designed in collaboration with Sesame Street as part of an environmental awareness campaign for children.

For now, these bags are being distributed free of charge at select outdoor events, as well as to volunteer cleanup groups and schools.

And for animal lovers, MAQ offers the Mottainai series of bags featuring images of teary-eyed penguins, seals and polar bears, which turn the neighborhood trash heap into a friendly reminder of the fragility of our planet. A portion of the profits go to the Green Belt Movement (a grassroots environmental NGO established by Kenyan political activist, environmentalist and 2004 Nobel Peace Prize winner Wangari Maathai), which has planted millions of trees across Kenya to prevent soil erosion.

Garbage Bag Art Work trash bags are available at various locations in Tokyo or at the Mottainai online shop (Japanese).

Hit the beach anywhere in Japan, and you are likely to see endless piles of tetrapods — enormous four-legged concrete structures intended to prevent coastal erosion. By some estimates, more than 50% of Japan’s 35,000-kilometer (22,000-mi) coastline has been altered with tetrapods and other forms of concrete. Critics, who blame the tetrapod invasion on decades of excessive government spending designed to bolster the construction industry, argue that in addition to posing a danger to swimmers, surfers and boaters, tetrapods actually accelerate beach erosion by disrupting the natural processes that shape the coastal environment. Meanwhile, others have developed an aesthetic appreciation of the tetrapod landscape, as evidenced by a host of stunning Japanese tetrapod photos on Flickr.

Japan’s Ministry of Economy, Trade and Industry (METI) has released a few details about the “Zero Emission House,” a state-of-the-art green home under construction at the site of the upcoming Hokkaido Toyako G8 Summit, where environmental issues will be high on the agenda.

Incorporating the latest in sustainable building technology, the 280-square-meter (3,000 sq ft) Japanese-style home is designed to have a small carbon footprint. A 14.5-kilowatt solar array and a small 1-kilowatt wind generator provide power to the home, which is equipped with next-generation energy-saving appliances, thermal insulation glass, vacuum insulated panels and a green roof. The interior is illuminated by a system of light ducts and OLED lamps.

Honda’s Asimo humanoid robot — whose exact carbon footprint size is unknown — will be on hand to serve tea to guests, who are welcome to test-drive the electric vehicles in the driveway and soak their feet in the fuel cell-powered foot bath.

Construction of the 200 million yen ($2 million) home is scheduled for completion at the end of June, at which time it will be unveiled to the foreign press. After the summit, plans are to transport the house to another location, where it will be opened to the general public.

SOTAB 1 (Spilled Oil Tracking Autonomous Buoy 1) is a 110-kilogram (243 lb.) GPS-equipped robot that measures 2.72 meters (9 ft.) from top to bottom and 27 centimeters (11 in.) in diameter. It has imaging sensors that can spot floating globs of oil from a distance, as well as viscosity sensors that detect the presence of oil, and it includes a wind monitor, depth meter and water thermometer. When multiple robots are dropped into the water at regular intervals around an oil spill, they can provide a wealth of valuable data to cleanup crews and allow them to monitor a wide area.

Once in the water, SOTAB 1 begins searching for oil by reducing its buoyancy and diving underwater, where it trains its imaging sensors back up at the surface. When the robot sees something that looks like oil, it readjusts its buoyancy and floats back to the surface, using 4 fins to steer toward the oil slick. It then takes water samples and determines how much oil is present. As SOTAB 1 follows the oil around, it sends back real-time data about its location and the surrounding meteorological and oceanographic conditions.

Head researcher Naomi Kato, an underwater robotics engineering professor at Osaka University, says SOTAB 1 is still in the development phase, but he hopes to see it become commercially available in 2 to 3 years.

“We want to get the weight under 30 kilograms and extend the battery life to about 3 to 4 weeks,” says Kato, who began working on the robot in 2006. “We would one day like to see these robots become standard equipment on oil tankers.”
