A jumbo elephant weight > windmill can supply 1,000 Kw enough for the largest container ship You do understand, do you not, that a "60 tonne ship" isn't a whole Hell of a lot bigger than what a teenaged girl is sailing around the world right now? The "largest container ship" displaces 170,000 tons and her engines produce 80MW. Your "jumbo elephant weight windmill" has the same disadvantage as a much older and more developed technology called "sails". It doesn't work when there's no wind. And it doesn't matter how much power a "bloom box" can produce if it's not more cost effective than a conventional engine. It amazes me how people will read an article about a new gadget and take the whole thing as gospel truth. How can you tell a salesman is lying? His lips are moving.

Could they be used to store solar energy ie concentrated solar energy would heat the metal and then it would spring back releasing energy , thereby minimising the engine components? excerpts The SCiB has characteristics that make it very appealing. It performs like an ultracapacitor with rapid charge times, reaching 90% charge in about 5 minutes. It is good for thousands of cycles without extensive capacity loss, and it has a life span of 10 years or more. And, of potentially particular interest for vehicle manufacturers, it is able to perform even at low temperatures down to -30 degrees Celsius (-22 degrees Fahrenheit

No. You are still an idiot. -- Jim Pennino Remove .spam.sux to reply.
From: habshi on 2 Mar 2010 19:01 Jim keeps talking about govt incentives hurting taxpayers. In fact whenever govt spending has exploded, 1930s, ww2, and now under Obama , growth has boomed and the taxpayers have got richer. Its time to learn the lesson from China excerpt renewableenergyworld.com Another major advantage for Chinese solar companies is their ready access to finance amid the global economic downturn. Backed by China's preferential policies towards renewable energy, domestic solar modules makers have benefited from supportive local banks. "This is something that European companies do not enjoy," said Frank Haugwitz, former European Union Renewable Energy manager within the EU-China Energy & Environment Program. "Chinese companies have easier access to local finance institutions who could help them in their endeavor in developing new markets." Such new markets include North America. In its latest second quarter statement, Suntech reported that "major investment in the U.S. market has resulted in rapidly growing dealer network." The company now has more than 200 authorized dealers throughout the United States, Canada and Mexico. Like Suntech, other Chinese solar manufacturers are gearing up further expansion. As China's solar demand was awakened by government incentives last spring, Yingli Green Energy, a top Chinese solar manufacturer, opened a factory in South China's Hainan province in July, aimed at the domestic and Southeast Asia markets. And this year, Canadian Solar, another solar leader in China, will develop solar projects in South Korea together with LG Group. Furthermore, China's state-owned investment companies that are involved in overseas solar projects may drive up the country's solar modules sales around the world. For instance, China Energy Conservation Investment Corp., which previously partnered with several local solar module makers in China, is talking to European developers about financing solar projects in Germany, Spain and Italy, according to a December report from Wall Street Journal
