City Farming blooms with Baby Boomers

J-Cast news is reporting that shimin noen (市民農園, or farms located near cities) have increased threefold over the last 15 years, up to 3,382 sites for fiscal 2008, with local governments and NPOs inundated with applications for certain areas.

Around 70 per cent of these “farms” are 50 square meters, with the rental cost as little as 5,000 yen (about $58) for a year’s use. Many of these aspiring farmers are said to be middle-aged salarymen and retirees keen to get their fingers green.

Eco consumer innovations have been some of the biggest media topics for the last few years in Japan, as we have noted many times before. With the Baby Boom Generation set to begin retiring en masse, they are looking for ways to spend their days. No doubt, scandals with food safety (particularly processed gyoza dumplings made in China!) have also inspired a desire for safer, more natural food.

Though the much-publicized Ginza rice paddy (below) seems to be making way for planned construction work on the land (i.e. it’s going to be replaced by a building), there are still plenty of vibrant examples of eco urbanism.

The Atre mall inside JR Ebisu station in central Tokyo opened its rooftop soradofarm in September 2009, allowing people to literally do some gardening during their shopping trip.

Many of the “city farms” are in fact intended to be only cultivated at weekends or after work. People are seeking a rural, eco experience but in a way that does not interfere too much with the benefits of their suburban or urban lifestyles.

Cynics will say that they do little to improve Japan’s lamentable levels of self-sustainability, but they are certainly becoming a kind of “third space”, like karaoke booths and internet cafes: locations that act as unique living/relaxation/work areas that are not usually possible elsewhere.

Volkswagen Beetle converted to run on methane headed for the UK streets

Meet the Bio-Bug, a custom modded Volkswagen Beetle which has been converted to run on biogas — fuel created from human waste. The process of conversion isn’t brand new, but this will be the first automobile fully converted to run on biogas in the United Kingdom without any loss of performance. In fact, the car is so reliable that its makers believe it can “blow away” electric vehicles, and that consumers won’t even notice the difference. The Bio-Bug is a regular old 2 liter VW convertible modified to operate on both gasoline and compressed methane gas: once the methane runs out, the car reverts back to running on gasoline. The cars run on so little methane that just one regular sized sewage plant could run a car (or cars) over 95,000,000 miles per year. Developed by GENeco, a sustainable energy company in the UK, the Bio-Bug is going into a trial period, and the company plans on converting its entire fleet if successful.

Photon enhanced thermionic emission could double efficiency of solar cells

Engineers at Stanford have developed a process which can harness the light and heat of the sun simultaneously, which could lead to solar cells that are twice as efficient as those currently available. Called photon enhanced thermionic emission — or PETE for short — the process differs from traditional cells which lose efficiency as temperatures rise, and the materials needed to build the cells are cheap and widely available. The engineers got around the lower efficiencies by coating a piece of semiconducting material with a thin layer of the metal cesium, which enables the material to use both heat and light simultaneously. While the materials as currently demonstrated work best in very high temperatures, the researchers indicate that in the near future, the materials could have wide enough application to make them competitive with traditional forms of energy. Hit the source for the full story.

Haier’s heat-exchanging Power Pad promises to make long, hot showers a little more efficient

Haier's heat-exchanging Power Pad promises to make long, hot showers a little more efficient

Major appliances are major energy drains, and if you have a traditional, tank-based hot water heater it can be a major factor in your monthly utilities bills. Haier‘s Power Pad promises to make those things have less of an impact on people’s finances — at least when it comes to showers. It’s a heat exchanger that you stand on whilst washing that man right out of your hair, water running off your toned body and through the vanes in the Pad, warming the cold water that’s pumped through it. That water is then deposited into the hot water tank, which now has a little less work to do. Haier is hoping to get this to market in China within the next two months for ¥4,000 (about $600) and, by that time, boost its efficiency to 30 percent. That’s still 10 percent lower than the EcoDrain we spied last year, but we have a more practical concern: what happens when that thing gets clogged with hair and various bathing products? It doesn’t look particularly easy to clean.

Inhabitat’s Week in Green: of mirror cubes and urban icebergs

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

With summer in full swing, this week Inhabitat watched the mercury rise as the world’s largest thermostat burst forth with an array of 72,000 building-mounted LEDs. We also kept things cool with a remarkable plan to transform frozen construction sites into event-hosting urban icebergs. And if you haven’t made plans for a summer vacation yet, might we recommend this stunning Swedish “Treehotel” housed within a silvery mirror cube in the sky?

Heartening news rang forth from the renewable energy sector this week as a UN-backed study reported that the building of new renewable energy plants has officially overtaken fossil fuel plants in Europe and the US. We also took a look at two brand new types of power plants — the world’s first hydrogen-driven power plant in Italy and the first hybrid coal-solar power plant in Colorado.

The past week also saw several remarkable advances in clean tech, starting with MIT’s latest innovation, a new type of high-tech fiber that can transmit sound, light, and generate electricity. We also paid homage to one of our all-time favorite sources of (surprisingly green) home entertainment – the Roku Box.

Researchers develop air conditioning that’s 90 percent more efficient, bone chilling

Everybody loves maxing out in the sweet chill of their air conditioning in the hot summer months, but it’s inefficient, expensive, and extremely unfriendly to the environment. The good news today, however, is that researchers have developed an air conditioning system that could be up to 90 percent more efficient than standard setups. How so, you ask? The new tech, called DEVap, uses liquid desiccants to make dry air using heat and evaporative coolers take dry air and make cold air, making it far easier to cool already dry climates. Additionally, DEVap uses salt solutions in place of environmentally naughty refrigerants, CFCs, and HCFCs — the main contributors to global warming. The tech is still in the lab, so until then you’ll just have to keep fanning yourself off (or having your friend do that for you).

ECO vending gives mobile consumers greener choices

It’s almost a cliche to say that the Japanese consumer likes vending machines. Given the huge ECO movement that has been sweeping industries here over the last few years it was inevitable that companies would start looking at these convenient dispensers and ways to make them greener.

CScout Japan investigated a lot of these trends as part of its comprehensive ECO Japan report earlier this year, and continues to monitor local ecology developments. Let’s take a look at the vending machines that are making efforts to be make on-the-move consumers more ECO.

Coca-Cola Japan is certainly a leader in this field, having developed some of the first stand-out prototypes. (Coca-Cola have also created great eco-packaging for consumer products, such as the I LOHAS and Plant Bottle.) Now they are going that step further and actually integrating ECO vending machines on a wider scale…

ecoru-solar-coca-cola-vending-machine

You should start to see their newest machine, the ecoru/solar, which comes with solar panels on the top, popping up over the course of 2010. Coca-Cola is installing 1,500 units around the country; a mere fraction of the 2.4 million beverage dispensers lining the roads (of which Coca-Cola is said to own a third) but certainly progress nonetheless.

The ecoru/solar uses energy-efficient LED lighting, as well as a heat pump, HFC-free refrigeration and vacuum insulation. Of course, this saves Coca-Cola money in electricity to supply the machine, meaning they have lower overheads — and can pass those savings onto the consumer. Given that the planet also benefits then everyone’s a winner!

eco-vending-machine

Fuji Electric also produced the E3 vending machine, which also gets energy from a solar panel and insulates in the winter by growing moss on its side. It collaborated with Coca-Cola to create the e-40, one of the original, ground-breaking vending machines, in 2008, which used 40% less energy than other machines.

Dydo and Pokka — other major vending machine companies in Japan — have contributed to the trend through donations: parts of the sales from a drink go to forestries and other ECO schemes. Not quite so hi-tech but effective nonetheless.

Inhabitat’s Week in Green: surfing renewable energy, hexagonal LEDs, and ultra-efficient aerodynamics

The Week in Green is a new item from our friends at Inhabitat, recapping the week’s most interesting green developments and clean tech news for us.

This week Inhabitat reported live from the scene of New York Design Week, where we sifted through thousands of new home furnishings and interiors products to bring you the state-of-the-art in green design. Fresh from the floor of the International Contemporary Furniture Fair is this stunning hexagonal crystal LED light, which is composed of glowing geometric blocks that snap together to form a myriad of shapes. We were also impressed by this beautifully finished wood calculator that multiplies its green factor with sustainably-sourced materials.

The past week was also surging with developments from the field of renewable energy – first we were excited to see the unveiling of the Oyster 2, an offshore wave-harvesting energy plant that improves upon its predecessor with a simpler design, fewer moving parts, and a 250% increase in energy generation. Google, HP, and Microsoft are also getting into the green energy game with plans to tap an unexpected energy source to run their data centers – cow dung! Google also led the charge towards cleaner energy this week by funding a new type of jet engine-inspired geothermal drill that uses superheated streams of water to bore through previously impenetrable surfaces.

Speaking of jets, MIT has just unveiled several ultra-efficient airplane designs that are capable of cutting fuel use by a whopping 70%. The auto industry also received a jolt of energy as Toyota announced a partnership with Tesla that will boost California’s flagging economy and likely lead to more affordable iconic electric vehicles.

The field of wearable technology saw several innovative advancements this week as well – safe cyclists rejoice, because a group of Indian students have designed a $22 Solar and Wind Powered Bike Helmet. Meanwhile, a group of Colorado State University seniors have designed a medical incubator backpack unit that they believe can reduce baby deaths in medical emergencies.

Finally, we shined light on several brilliant advancements from the field of solar technology, starting with China’s plans to build the “biggest solar energy production base” in the world. We also looked at the HYDRA, a solar-powered hydrogen fuel cell system that can reportedly generate 20,000 gallons of pure water a day, and green energy got literal with the unveiling of the first leaf-shaped crystalline silicon solar panels.

Back to the future: the bamboo, washi electric car

We recently were lucky enough to meet the makers of the Meguru, an electric car made with traditional Japanese crafts and techniques.

Resembling a kind of rickshaw eco car, the Meguru is comfy and looks pretty stylish, in a funky antique sort of way. The main body is iron coated with urushi (lacquer), the flooring made from real bamboo and, most noticeably, the “door” is a fan-shaped washi (Japanese paper).

meguru-history-eco-car-japan-1

Developed jointly by Yodogawa Group and Kinki Knives Industries Corporation in Osaka, the makers hope that Meguru will become a hit in traditional towns like Kyoto and Nara. They plan eventually to offer the light vehicle at a cost of around a million yen (c.$10,000).

Its batteries can be powered by ordinary household electrics and a two-hour charge lets you drive non-stop for forty kilometers (about 25 miles). Fairly leisurely in pace, Meguru can still pick up some speed, apparently up to 40 km/h (25mph). The car is actually already registered as a road vehicle and can be driven in public. so keep your eyes peeled!.

On the right is a picture of me enjoying the cushioned seating with the very friendly Kiyonobu Agata-san, one of the people behind the project.

A few years ago a Japanese university developed the BamGoo, a small EV made of bamboo. Could this be the start of a new Back to Japan eco car trend?
