NEW ZEALAND SCIENTISTS DESIGN MUCH CHEAPER SOLAR CELLS
GO SUN SOLUTIONS - Solar cell technology developed by the Massey
University's Nanomaterials Research Centre will enable New Zealanders to
generate electricity from sunlight at a 10th of the cost of current
silicon-based photo-electric solar cells. Dr Wayne Campbell and
researchers in the centre have developed a range of colored dyes for use
in dye-sensitized solar cells.
The synthetic dyes are made from simple organic compounds closely
related to those found in nature. The green dye Dr Campbell is synthetic
chlorophyll derived from the light-harvesting pigment plants use for
photosynthesis. dyes being tested in the cells are based on hemoglobin,
the compound that give blood its color.
Dr Campbell says that unlike the silicon-based solar cells currently on
the market, the 10×10cm green demonstration cells generate enough
electricity to run a small fan in low-light conditions - making them
ideal for cloudy climates. The dyes can also be incorporated into tinted
windows that trap to generate electricity.

SUBSTITUTE FOR WRAPPING PAPER
SUSTAINABLE IS GOOD - Shoppers at the Museum of Modern Art stores may
have noticed something different on their latest visit. The packaging in
all MOMA's retail shops is now green. . . Their gift packaging including
boxes and all bags is now made from a revolutionary sustainable material
called TerraSkin made by Design & Source Productions in New York.
TerraSkin is made from a combination of large amounts of mineral powder
with a small quantity of non-toxic resin to create an environmentally
friendly paper. TerraSkin has very similar characteristics to
traditional paper . . . It also has many eco-friendly characteristics.
First, the production of TerraSkin requires no water, so the paper
making process incurs no water pollutants. Second, as TerraSkin contains
high proportions of inorganic mineral powder, when the end user is done,
the used paper will degrade when left out in nature for approximately
three to nine months back into the mineral powder. If preferred, used
papers can also be incinerated safely as non-toxic resins will not emit
smoke or poisonous gas by-products.
