Pollution Dress is Stylin’

- Adam Clare

A fashion designer has made a dress with a CO2 detector in a dress then lights up using LEDs depending on the concentration of CO2 in the area.

The Climate Dress is made of conductive embroidery, over hundred of tiny LED lights inserted into the embroidey, a CO2 sensor and an Arduino Lilypad microprocessor. The LEDs visualize the level of CO2 in the nearby surroundings and are powered trough the embroidery!
For The Climate Dress we used soft conductive thread that has a similar consistence to the kind of thread used for traditional and industrial embroidery production. This way it is possible to make embroidery that become more than an esthetical element in clothing and interior textiles.

The embroidery becomes functional conveying electricity and computer information and thereby give “power to the dress”. The dress senses the CO2 concentration in the air, then accordingly creates diverse light patterns varying from slow, regular light pulsations to short and hectic. The technology, which integrates ”soft circuits” into the production of embroidery, is an innovative process. It is the result of a fruitful collaboration between Copenhagen based design studio diffus, Swiss embroidery company Forster-Rohner, the Danish research-based limited company Alexandra Institute and finally the Danish School of Design.

Bacteria Batteries

- Adam Clare

Regular readers know that algae is a potential source of energy (and many other things), and in other small-life form news some researchers have found that bacteria can be used as a battery.

WorldChanging has all you want to know about bacteria batteries.

The system’s active ‘ingredients’ are a combination of tiny microbes and CO2. Placed under an electrical current – for example from an off-grid renewable power source such as wind or solar – the microbes convert the CO2 into methane. Professor Bruce Logan, head of the research team, explains that they work in a similar way to the natural process found in marshes.
He suggests that the initial carbon dioxide needed for the chemical reaction could even come from industrial sources: “CO2 is soluble in water, so the gas stream could be bubbled or transferred” in pipes from factories, for example. The ‘battery’ is designed to work as a closed loop, capturing and reusing the CO2 that’s released when the methane is burned.

Fake Plastic Trees

- Adam Clare

I wonder if these fake plastic trees will look like the real thing. Researchers are advocating the use of fake trees that absorbs CO2 and turns the gas into something useful. I wonder if these fakes can be what we need all the time near highways and airports.

The “tree” uses plastic leaves that capture the carbon dioxide in a chamber. The carbon dioxide is then compressed into liquid form. The tree captures the carbon without the need for direct sunlight, which means that, unlike traditional trees, the synthetic trees can be stored in enclosed places such as barns, used anywhere, and transported from one site to another regardless of conditions.
Lackner says the captured CO2 could be used to create fuel for jet engines and cars, the two most common carbon emitters. In other cases, the CO2 could be used to enhance current production of vegetable produce.

I wonder if you’ll need a fake plastic watering can for these trees. I know that doing that would wear me out; if only I could be who the trees wanted.

The only reason I posted this is because when I read the article I couldn’t get this song out of my mind:

CO2 Turned into Fuel by Solar Powered Device

- Adam Clare 1 Comment

A device that can transform CO2 in fuel can prove to be revolutionary. The very idea of using the sun’s rays to get rid of CO2 is great in itself – making that same process create a type of diesel fuel is even better. In theory, waste from inefficient gas cars can be used to make cheaper fuel for more efficient diesel cars, which would drive demand for more diesel cars from cheaper fuel.

The researchers housed a 2-centimetre-square section of material bristling with the tubes inside a metal chamber with a quartz window. They then pumped in a mixture of carbon dioxide and water vapour and placed it in sunlight for three hours.

The energy provided by the sunlight transformed the carbon dioxide and water vapour into methane and related organic compounds, such as ethane and propane, at rates as high as 160 microlitres an hour per gram of nanotubes. This is 20 times higher than published results achieved using any previous method, but still too low to be immediately practical.

If the reaction is halted early the device produces a mixture of carbon monoxide and hydrogen known as syngas, which can be converted into diesel.

Canadian Scientist Create CO2 Scrubber

- Adam Clare

A researcher from the University of Calgary has create a machine that essentially scrubs carbon dioxide from the atmosphere. The Tech Herald explains:

The team now believes it is close to achieving that goal with the development of a relatively simple machine that can capture, or “scrub” the trace amount of CO2 present in the air at any place on the planet.
“The climate problem is too big to solve easily with the tools we have,” explained Keith, director of the Institute for Sustainable Energy, Environment and Economy’s (ISEEE) Energy and Environmental Systems Group and a professor of chemical and petroleum engineering.
“While it’s important to get started doing things we know how to do, like wind power nuclear power and ‘regular’ carbon capture and storage, it’s also vital to start thinking about radical new ideas and approaches to solving this problem.”
