I think you are so low brained I have to spell out stuff to get it to sink into your tiny low wit parrot brain. You brain is a never was and never be a thinker Sam go straight to Google "Its the only friend for you' Oi Ya Bert
From: habshi on 26 Nov 2009 16:26 The problem of energy storage seems to have been solved excerpt http://www.energymatters.com.au/index.php?main_page=news_article&article_id=678 Using hydrogen as a clean fuel with relatively endless reserves certainly has potential, but also faces many challenges. For example, the production of hydrogen requires a great deal of energy. However, some companies have made great inroads in utilising renewable energy sources such as wind and solar power in the hydrogen harvesting process. One such company is Avalence LLC; based in the USA. Avalence�s hydrogen generators are electrochemical devices that convert water and electricity into high purity pressurized hydrogen gas through the process of electrolysis. Avalence's Hydrofiller system is a high-pressure hydrogen gas generator that doesn't require a separate compressor. According to the company, this cuts capital costs by up to 50% and operating costs by 20%. Given the lower energy requirements, it also means the Hydrofiller system can be powered by solar panels or wind turbines. The company says electrolysis is the most direct method for creating hydrogen fuel from fluctuating renewable energy sources. The Avalence Hydrofiller enables 24-hour electricity availability from intermittent energy sources from not just solar and wind, but also hydraulic and tidal power. In large applications, hydrogen produced during inexpensive or excess power production periods can be stored and later distributed to stationary fuel cell generators to supply electricity during expensive or peak demand periods.
From: habshi on 26 Nov 2009 16:32 excerpt http://www.theglobeandmail.com/report-on-business/rob-magazine/5-businesses-that-will-save-the-world/article1375975/ In Germany alone, the renewable energy industry has created more than a quarter of a million new jobs in the decade since the Bundestag passed the world�s most ambitious green-power legislation in 2000�this without introducing any new taxes and at a total cost to the average German household of about $50 per year. This �feed-in tariff� model, which requires utilities to purchase renewable electricity at above-market prices, has been quickly copied across Western Europe, most of which is at least a generation ahead of Canada in the shift to a sustainable low-emissions economy. There�s enough energy in the world�s crust to create all the electricity the world needs,� says Fairbank, president and CEO of the Vancouver-based firm. South of the border, there�s been something of a geothermal boom going on for about five years. The U.S. already has 3,000 MW But the real future of geothermal may lie in the dry heat that is trapped in rock, which, unlike trapped pockets of hot water, can be found under any point on the Earth�s surface. At a depth of 3,000 to 4,500 metres, the rock temperature is about 150 C to 250 C, which is the economic sweet spot for geothermal projects (any deeper and the costs become extortionate). Engineers can force water through natural or engineered fractures so that it gathers up heat before it�s pumped back as steam to drive turbines. There are still formidable obstacles: Drilling even a few thousand metres is costly, and techniques The group�s technical point of departure is that the solar radiation striking the Earth�s 36 million square kilometres of desert in a six-hour period is approximately equivalent to the world�s annual fossil fuel energy production. �Any conceivable global demand of energy, today or in the future, could be produced from solar energy in deserts,� according to a technical report produced for Desertec. Not bad for a morning�s work. Desertec�s backers are proposing a series of concentrated solar thermal plants, with banks of reflectors directing the sunlight onto liquid-filled tubes. The superheated fluid is used to drive turbines and generate electricity. There In September, Norway-based Statoil ASA, the world�s largest offshore fossil-fuel producer, added a strange new device to its vast array of North Sea energy installations: the world�s first floating industrial-scale wind turbine. Dubbed �Hywind,� the new project is an unlikely hybrid of a standard wind turbine and the mooring system used to stabilize oil rigs in the high seas. The technology is off-the-shelf and deceptively straightforward: Take an oil platform�s �Spar-buoy��a 100-metre-tall ballast tank tethered to the seafloor, up to 700 metres below, by three thick cables�and crown it with a 2.3 MW Siemens wind turbine. Install enough turbines in one spot to justify the cost of the submarine transmission cable, and then figure out how to keep them humming as they rock and sway in the pounding waves. If you can manage all that, you might just capture a new segment of the booming wind-power market�with economic potential exponentially larger than any wind sources yet uncovered. �The problem with most renewables is that they don�t add up,� says Statoil�s Brage Waarheim Johansen. �This can add up.� The price tag�about $80 million to keep a single test turbine moored and spinning out juice from 10 kilometres off Norway�s coast for two years�is still far too steep for the mass market. But Statoil is confi-dent the technology and the economics are sound, and Johansen and his colleagues are already envisioning enough floating windmills to power all of Norway�and perhaps, one day, enough installed up and down the long, heavily populated coasts of North America to fundamentally
