, and this device is no exception. "As the water flows past at a rate of 15 liters per minute, the lamp's radiation deadens the DNA of any bacteria, viruses or molds. Water infested with as much as 1,000,000 E. Coli bacteria per liter leaves the system completely clean. " WaterHealth International, Inc.

China breathes life into Kyoto: In ratifying the Kyoto Protocol, China.. introduces a major player to the as yet nascent global market for carbon credit. China by virtue of its size adds massive liquidity to the system ..
Projects carried out under the mechanism will benefit from an additional revenue stream derived from their emission reductions. Hong Kong is certainly in a position to benefit .. Hong Kong companies, can bring skills and experience with clean energy technologies. Many greenhouse gas emission reduction measures also reduce local pollutant emissions. .. This creates potential win-win opportunities in the Pearl River Delta and southern China, which business and governments in Hong Kong and Guangdong should pursue vigorously. .. Companies experienced in doing business in China will fare best, as they tap into China's virtually unlimited supply of carbon credits. ..
The most obvious projects to focus on are those that require initial capital investment, and deliver savings that pay back the capital even without revenue from emission reductions. Typically these are process-redesign or energy efficiency projects. Decisions from the recently formed Clean Development Mechanism Executive Board confirm that such projects will qualify under its structure. Projects using methane from landfill gases or coal mine methane are most likely to be targeted due to the damaging greenhouse effect of the gas. Fuel conversion projects are also likely to be targeted.
The caps on Annex I countries apply to emissions for the period 2008-2012. But the accord provides for Clean Development Mechanism projects in place since January 1, 2000, to save or bank Certified Emission Reductions against Annex I emission caps for 2008.
The strongest demand for emission reductions from China is likely to come from Japanese companies. Japan needs millions of tonnes of reductions, and with its energy sector profile would face extremely high costs to achieve these reductions. Japan recently announced a programme to investigate clean development mechanism projects across Asia. It is keen to be ahead of the field in the race to find the lowest cost opportunities to offset emissions. 8:59:19 AM
Moroccan wind farm has steady wind, few bird problems:
"Morocco's first wind farm at Koudia Al Baida, 30 kilometers east of Tangiers, has an annual output of almost 200 million kWh, which represents about 2% of the country's electricity consumption and is equal to the consumption of about 400,000 inhabitants. The site, near the Straits of Gibraltar, has exceptional wind quality with powerful, regular winds. .. These conditions permit generation at full power during 4,000 hours per year (46%). .. During the period, 9,000 long flight birds and 1,300 small sparrow like parrot passerines were observed .. The long-flight birds react to the generator propellers by going round them to the west either by using the special corridors [designed between batches of turbines] or by flying at a higher altitude. The passerines use the corridors exclusively. Only two migrating birds have died after colliding with generator blades. .. In the Koudia al Baida project there are 84 generators spread out along an 8 kilometer crest at an altitude of between 370m and 560m each with a capacity of 600 kW and a combined output of 50.4 MW. Each weighs 26 tons, has a mast height of 45 meters, and has an 8.5 ton propeller of 42 or 44 meters diameter." Note: onshore wind power typically runs at 30% capacity, offshore typically at 60%. 6:53:20 AM
