Building Tower to Babel: huge upward wind power stationsEnviroMission would like to build with huge scenery consumption an up wind power plant. However, the electric power yield is in proportion to the surface demand very small.200 MW peak power should cover the power consumption of 200,000 typically Australian house holds. But thus an upward wind power station functions only with sunshine. So why not simple mount photovoltaic on the roofs of this 200.000 houses? Let's take 200.000 spacious Australian one family houses with 200 squaremeter roof for photovoltaic each. What comes out there?
200,000 * 20 kW Peak does not make 200 MW like the upward wind power plant, but 4,000 MW. Thus for what scenery-destructive hugey technology if one could have 20 times more electric power completely without such overexploitation in the nature, simply by better use of the roof surfaces?
Why the most expensive huge technology, instead of solar technology for every single house? 200 MW photovoltaic cost nowadays 800 million EUR. Would really like somebody to put up the assertion that one can produce a 1 km high tower with huge surfaces all around for less than 800 million EUR? 800 million EUR is the market price of 200 MW photovoltaic which can produce the same amount in energy. What are, however, 800 million EUR with such a large-scale project? With a 1000 m high tower only 800,000 EUR per meter construction height are available. And where is the money for the gigantic surfaces?
The project should finish in 2010. At the expected price reduction of photovoltaic, the cost of the up wind power plant could be reached by 625 million EUR photovoltaic for the same energy yield. Then with the price trend to be expected with the photovoltaic the building cost face photovoltaic to the value of only 625 million EUR for the same energy yield. |
