Most of the "news" in relation to wind power and residential solar for that matter is usually in the form of a press release. Unfortunately, the first time a consumer for a particular product, like a windmill, assumes the information he or she has just read the press release sufficient to make an informed decision to purchase. Nothing could be further from the truth.
Here is a good example. There is a wind turbine for private use of the designer Philippe Starck, better known asDesigners of consumer products like toothbrushes and wristwatches.
His new residential wind turbine, which he called "democratic design" is a rectangle of transparent polycarbonate about 12 feet wide and capable of producing 18 feet tall and, according to the press release on Inhabit.com of 20 percent 60 per cent of the annual electricity needs at home. Democratic design will reportedly sell for $ 630 when it is available in September 2008.
The project was realized with the help of Pramac, aMilan, Italy-based manufacturer of portable and standby generators, and recently in the field of renewable technologies.
After the comments submitted by readers of the press release, were thrilled at the prospect of cutting the electricity bill for a half-time investment of only $ 630 Who would not? The problem is, a complete grid-connected wind turbine requires additional components (such as a tower?) Are not included in the price $ 630.
AnotherPlanning is the problem with democratic performance projections vague. The performance is expressed as kilowatt hours of energy consumption not as a percentage of your home. Every other wind turbine, which has now sold a specific kWh (kilowatt hour) rating. If the kWh rating is combined with data from local wind speed, you can cover the size of a wind turbine at a certain percentage of your home for energy, not to the contrary.
Also interesting is the extent to which participating in the PramacProduction and distribution of
Democratic Design. When I visited their site, I discovered that, in fact, recently participated in the distribution of solar photovoltaic systems, but there was no talk of his involvement with the democratic design done.
I find it strange that given a scheduled release fall - less than two months from the date of this article. This does not mean it will not revolutionize the new design of wind turbines a day, but at this stage is moreimportant for the practical aspects of design and as Democrats who consider the impact on the estimated cost for a complete system of wind.
First, let's look at the breadth of this thing looking for. At 12 'x 18' high, this is not something you want to throw down in your garden for the neighborhood kids to try to jump in and out, apparently around. Neither you do not want to install anything with the size of your living room on the roof of your house.
The solution is to put it on a bracketTower. But I'm not an engineer, I can not say for sure if one of the towers would be used for wind turbines to accommodate others, or be adaptable to the democratic design. That said, prices for the towers, depending on the height and design. A 30 'tower braces, no installation costs about $ 800. While a 35 'tower monopoly, can also be uninstalled, costs around $ 3,400.
The next component is not included in the price of democratic design of the inverter. An inverter is necessary to convertthe DC (direct current) DC voltage produced by the turbine into alternating current generated by household appliances.
The inverter size is determined by the performance of the turbine. Assuming democratic design provides 30% of annual domestic consumption of electricity, you would need an inverter in the 3000-watt range will cost about $ 2.300.
I think you get the point. Already $ 3,000 - $ 6,000, the cost of Democratic Design was added without regard for the costs of installation orSpecial equipment such as a performance monitor.
But do not get me wrong, if the democratic design really works, the initial outlay for a complete system would still be in competition with other wind energy systems. But to get the approval from the state of design appropriate democratic and federal authorities, not for the tax benefits, to qualify to make renewable energy affordable.
Press releases are to create interest in a particular subject or product. And residentialWind energy news is no exception. That's right, keep in mind that most of them are news, but do not always contain all the facts.
