Two years ago I was interviewed about the future of the green kitchen, and suggested it might look much like Donald Chong’s design , saying:

Local food, fresh ingredients, the slow food movement; these are all the rage these days. A green kitchen will have big work areas and sinks for preserving, tons of storage to keep it in, but will not have a four foot wide fridge or a six burner Viking range. It will open to outdoors to vent the heat in summer, to the rest of the house to retain the heat in winter. The dining area will be integrated into it, perhaps right in the middle. A green kitchen will be like grandma’s farm kitchen- big, open, the focus of the house and no energy from the appliances will be wasted in winter or kept inside in summer.

It hasn’t happened yet, but there have been a lot of new ideas in how you design a kitchen, what you put in it, where it goes when you are not using it. We look at some of the sliding, changing reinventions of the kitchen. [ more ]

Poking out of the ground near the smokestacks of the Mountaineer power plant here are two wells that look much like those that draw natural gas to the surface. But these are about to do something new: inject a power plant’s carbon dioxide into the earth.

A behemoth built in 1980, long before global warming stirred broad concern, Mountaineer is poised to become the world’s first coal-fired power plant to capture and bury some of the carbon dioxide it churns out. The hope is that the gas will stay deep underground for millennia rather than entering the atmosphere as a heat-trapping pollutant.

Researchers at the Royal Institute of Technology (KTH) in Stockholm have managed to prove that fossils from animals and plants are not necessary for crude oil and natural gas to be generated. The findings are revolutionary since this means, on the one hand, that it will be much easier to find these sources of energy and, on the other hand, that they can be found all over the globe.

Green is the new black — and bamboo is the new titanium. After years of churning out glossy, metal-finish, high-polish products, electronics companies are taking their design cues from nature — and trying to pick up the sheen of eco-friendliness — by wrapping their products in bamboo veneers.

Bamboo has become the “it” material for many gadget designers. PC maker Dell has launched its Studio Hybrid PC with the option of a bamboo case, while Asus offers a Bamboo series notebook. There are also bamboo speakers, a keyboard, mouse and USB hub available, all wearing the woody-stemmed grass. [ read more ]

University of Calgary climate change scientist David Keith and his team are working to efficiently capture the greenhouse gas carbon dioxide directly from the air, using near-commercial technology.

In research conducted at the U of C, Keith and a team of researchers showed it is possible to reduce carbon dioxide (CO2) – the main greenhouse gas that contributes to global warming – using a relatively simple machine that can capture the trace amount of CO2 present in the air at any place on the planet.

“At first thought, capturing CO2 from the air where it’s at a concentration of 0.04 per cent seems absurd, when we are just starting to do cost-effective capture at power plants where CO2 produced is at a concentration of more than 10 per cent,” says Keith, Canada Research Chair in Energy and Environment.

Would you still watch your favorite television program if you had to cycle for an hour before you could view it?

Couch potatoes will be horrified, but fresh advances in human-powered technology — where users power appliances through their own motion — could one day see a ‘workout-to-watch’ scenario become reality.

Human power is rapidly gaining in popularity worldwide as businesses seek ‘greener’ methods of operating. [ read more ]

From sensors in workout gear that monitor sweating while you run at the gym, to underwear that aims to detect cancer cells, the contents of our wardrobes have been quietly undergoing a revolution. Over the past decade, there has been a rise in the number of ways that technology is being incorporated into items of our clothing.

Trials of smart clothes that can repel insects and mask nasty odours such as cigarette smoke have proved successful and are already being marketed.

A large-scale tidal-power unit has started up in Northern Ireland.

The world’s first commercial tidal-power system has been connected to the National Grid in Northern Ireland. Built by the British tidal-energy company Marine Current Technologies (MCT), the 1.2-megawatt system consists of two submerged turbines that are harvesting energy from Strangford Lough’s tidal currents. The company expects that once the system, called SeaGen, is fully operational, it will be able to provide electricity to approximately one thousand homes.

The system is currently being tested and has briefly generated 150 kilowatts of power into the grid. But it has also damaged one of its rotors due to a failure in the control system when the rotor began turning too fast. Although the problem was a minor setback, the unit is not expected to start running continuously and at full capacity until November, says Peter Fraenkel, the technical director at MCT.

Materials that change temperature in response to electric fields could keep computers–and kitchen fridges–cool.

Thin films of a new polymer developed at Penn State change temperature in response to changing electric fields. The Penn State researchers, who reported the new material in Science last week, say that it could lead to new technologies for cooling computer chips and to environmentally friendly refrigerators.

Changing the electric field rearranges the polymer’s atoms, changing its temperature; this is called the electrocaloric effect. In a cooling device, a voltage would be applied to the material, which would then be brought in contact with whatever it’s intended to cool. The material would heat up, passing its energy to a heat sink or releasing it into the atmosphere. Reducing the electric field would bring the polymer back to a low temperature so that it could be reused. [ read more ]
