    Well its certainly not all hot air! The Gold Coast "Green Waste to Energy" Power Plant is shaping up well. In fact I can't believe the amount of progress they have made since I first visited the site.

    See this link for recent pics from 16th June 2002! There are more pics expected next week as the Turbine and Boiler arrive for installation.. Looking Good.

    EnviroStar Energy Limited is pleased to announce that the final major
    equipment (the key component of the Stapylton Plant), namely the
    Steam Generator/Boiler have now been completely fabricated and are in
    transit to site where they are to be installed by the EPC Contractor,
    Energy Equipment Australia Pty Ltd. Commissioning is scheduled for
    29th June.

    The steam generator weighs approximately 100 tonnes having dimensions
    of 8 metre wide by 8 metre in length, and stands 22 metre tall.

    Transporting these key components for the Plant is a major task
    involving significant traffic disruption and requiring comprehensive
    permitting from and the assistance of the RTA and the DMR.

    The Energy Equipment Fluid Bed Combustion (EEFBC) system being the
    patented technology employed at Stapylton under exclusive license to
    EnviroStar, operates as a single unit with the Steam Generator. This
    "one of a kind system" is designed and fabricated to prevent multiple
    aggressive expansions and contractions when the two sections are
    exposed to a high pressure and temperature of up to 1,200 deg C. This
    system also prevents any gas leakage from the combustion chamber
    operating under negative pressurization.

    The bottom part of the combustion chamber, known as the 'bed', is
    filled with sand and when pressurized through injectors the sand
    moves in a liquid form referred to as 'fludised'. The chamber is
    heated to a high temperature and the sand retains the heat. The
    process is known as Fluid Bed Combustion (FBC).

    The EEFBC will be operating at a temperature of 850 deg C in the bed
    section where fuel (green waste) with high moisture contents, for
    example grass off cuts, is fed. The fuel simultaneously combusts and
    produces hot gas which ignites to create a step-up in temperature to
    1200 deg C releasing enormous heat energy. The heat energy is fired
    directly below the superheated water tubes in the Steam Generator to
    produce a superheated steam with a high pressure (35MPa) and a high
    temperature (400 deg C). The superheated steam is then injected into
    the Steam Turbine, which drives the electricity generator.

    The EEFBC worldwide patents which relate to processes which control
    the extreme combustion temperatures in EnviroStar's Stapylton Plant
    creates a system which prevents the formation of toxic and greenhouse
    gases and thereby prevents toxic gas emissions. Therefore,
    EnviroStar's Electricity Plant at Stapylton qualifies for both
    Renewable Energy Credits and Carbon Credits.

    The FBC technology has been recognised to be the world's best
    practice for waste to energy conversion as stated by the University
    of California.

    The foundation slabs completed at Stapylton include more than 650
    anchor bolts which weighing over 20 tonnes and which have been fixed
    under survey with high precision. The key components will be
    installed on these anchor bolts.

    The Fuel-Handling Unit is progressing into its first week of
    installation. This state of the art technique includes a positive
    displacement and feed system for the green waste and is designed to
    have the capacity to store enough fuel for 12 hours operation with a
    feed rate system which can handle 150 tonnes of green waste per day.

    On the 8th of February this year, EnviroStar announced it had
    received its Generating License from the State Government of
    Queensland, Generating Authority G01/02.

    On 26th March, EnviroStar announced its registration with the Office
    of Renewable Energy (ORER). Progress in the final construction of
    EnviroStar's 5MW Stapylton Plant puts the Company in a position where
    it can begin electricity generation to meet sales contracts with
    Energy Australia and thereby enjoy the benefit of a long term and
    sustainable cash flow commencing in the third quarter of this year.

    EnviroStar is now in a position to begin to plan the next phase which
    is to initiate Stage 2, the implementation of the Company's Green
    Power projects which have obtained Approvals, EPA Licenses and Signed
    Power Sales Contracts for 20MWe at Stapylton and 20MWe at Morwell in
