  • Greenpeace hunts the whale hunters

    The Greenpeace ship, The Arctic Sunrise, was deliberately rammed and
    damaged by the Nisshin Maru, the factory ship of the Japanese whaling
    fleet. The Greenpeace web site is keeping the world up to date with
    their peaceful pursuit, monitoring of the number and types of whales
    killed and with attempts at preventing the killing of whales in the the
    Southern Ocean. This is happening now. Go to their web site:
    www.greenpeace.org for continuous updates.

  • Energy Footprint Calculator available for your PC

    Research institute, Integrated Sustainability Analysis, at Sydney
    University has developed a software tool for calculating the
    ecological footprint of any organisation. The reports
    on Australia’s ecological footprint,
    Balancing Act, that
    was released last May in conjunction with the CSIRO
    used the
    same methods employed in the new
    software. The user-friendly software, known as the Footprint Machine,
    is aimed at local governments and small to medium enterprises.

    The
    tool has been used on Fraser Island’s Kingfisher report to rate each
    item on the menu according to its impact on the environment.
    Apparently beef is the most resource hungry food on the menu.

  • Australian developers to generate power on site

    Building developers carving new
    suburbs out of semi-rural environments will spend $37billion on
    energy infrastructure in the nex
    t fifteen years, according to
    environment business magazine, WME. They can reduce this investment
    by generating electricity on site, using natural gas or alternate
    energy, the magazine reports.

    Australian company, GridX has developed
    a system that provides heating and cooling to homes in the locality
    as a byproduct of electricity production. Each unit feeds up to 12
    homes with a network of generators able to be strung together to
    service localities of up to 200 homes. Developers investing in the
    system can further offset their costs through the sale of electricity
    to the owners of the houses, effectively a captive market.

  • How did we fair with electricity consumption in 2005?

    Queensland’s average electricity demand was highest in three
    summer months and up in all 12 months of 2005.

    SA average demand was down in 10 of 12 months in 2005, with two
    winter months and one summer month in three highest demand range.

    The three winter months continue to have highest average demand
    in NSW, with top month’s average 7.5pc higher than top summer
    month.

    Vic average demand was down in 7 of 12 months in 2005, but not
    surprisingly it was the three winter months that remain the
    highest.

  • Painting all Earth’s roofs could drop global temperature

    More sophisticated modelling required for confirmation: A
    zero-dimensional model, however, excludes the atmosphere and,
    crucially, the role of clouds. It would be interesting to see if more
    sophisticated models predict a similar magnitude of cooling.

  • Dutch and Norwegian scientists generate electricity by mixing sea and river water

    EU funding: It might seem like an exercise in scientific theory
    destined only for high-tech laboratories, but the creators and the
    European Union (EU), which funded the Norwegian research, believe the
    idea’s time might have come.

    Different methods used: The two projects used different methods
    to harness the electricity – the Dutch apply something called reverse
    electrodialysis while the Norwegians use a kind of osmosis.

    Reliance on membranes: However, both methods rely on membranes
    or thin films made of special material used for chemical separation. In
    the Dutch project, separation was done by membranes using an electrical
    current.

    Process like putting frankfurts in hot water: The Norwegian
    device applied pressure to force the water through membranes. Its
    inventors liken the process to making a hot dog. The skin of the
    frankfurt acted as a membrane, allowing more water in than the amount
    of salty water it let out. This increased the pressure inside and the
    hotdog burst.

    Still a long way to go: The two inventions still had a long way
    to go before they could be applied commercially. The Wetsus project,
    supported by a consortium of Dutch companies, had yet to be tested in a
    pilot plant.

    Norwegians have two small-scale plants: The Norwegian project
    was more advanced. It started in the 1990s and its creators had already
    installed two small-scale plants, but had yet to build a bigger
    demonstration plant to boost production.
