Light-emitting wallpaper could replace bulbs
WALES - Wallpaper which emits light could replace traditional light bulbs and cut carbon emissions within a few years.
The technology uses an electrical current to stimulate chemicals to produce light, and a Welsh company developing it has been awarded a grant of £454,000 from the Carbon Trust to help get it into homes and businesses.
The organic light emitting diodes (OLED), which can be coated on to a thin flexible film to cover walls like wallpaper, can also be used for flat screen televisions, computers and mobile phone displays. It needs a very low operating voltage and can be powered by solar panels or batteries, allowing it to be used outdoors to light road signs and barriers without the need for mains electricity.
Ken Lacey, the chief executive of LOMOX Ltd, said the company hoped to make it available to lighting and screen producers by 2012.

Carbon capture: How can we remove CO2 from the atmosphere?
BERLIN - The world is, on average, 1.1 degrees Celsius warmer today than it was in 1850. If this trend continues, our planet will be 2 – 3 degrees hotter by the end of this century, according to the Intergovernmental Panel on Climate Change (IPCC).
The main reason for this temperature rise is higher levels of atmospheric carbon dioxide, which cause the atmosphere to trap heat radiating from the Earth into space. Since 1850, the proportion of CO2 in the air has increased from 0.029% to 0.041% (288 ppm to 414 ppm).
