Sunflower stimulate the solar-thermal power plants of improvement of the inspiration

Sunflower on numerous floret of the tray lined have send, formed a rule of the geometric designs. In the solar-thermal power plants to used to gather the sun to generate power of solar array of improvement of the condenser brings new inspiration.
Sunflower flowers arrangement for the solar-thermal power generation with inspiration
This kind of design inspired by the sunflowers and array layout can make spotlighting solar thermal power station (CSP) area reduces by 20%, which in a certain degree to be large-scale land demand constraints of the solar power generation technology is very beneficial.
CSP power plant huge condenser the array, each array has half the size of a tennis court, it can will the sun beams gathered for installation in the liquid heating tube top, the liquid will produce after heating steam, thus driving steam turbine to conduct electricity. In the traditional array layout, the condenser is to the right to center tower goes around layer are deferred. Spain Gemsolar power array is in this way layout, covers an area of 185 acres, was completed in 2013, will be for about 25000 families provide electricity.

In view of this traditional arrangement of the massive demand for land, the Massachusetts institute of technology AlexanderMitsos mechanical engineers and his colleagues are looking for a kind of improved layout mode. They first established a evaluation condenser array of the efficiency of the computer model, and the Spanish Andalusia (Andalucia) of a PS10 called the CSP power station to the test. They found that the plant condenser are prevented some keep out sunshine, reduce the power station electricity generating efficiency. In order to improve the efficiency of power CSP power station, Mitsos and his colleagues to the condenser numerical layout optimization design. In their design, the condenser is arranged more closely, thus reducing the company's 10%.
A team members noticed, design of their distribution pattern in some elements and sunflower floret of the hovering arrangement is very similar pattern, and suggested that they should imitate these flowers. Mitsos and his colleagues began to investigate, the fact that this is a great idea. This amazing found that prompted them to develop a and sunflower flowers arrangement of more similar to the condenser simulation array. According to the mathematician earlier found the steering Angle of sunflower flowers, in the array, each piece of condenser is near its the lens with a 137 degree Angle arrangement.
Mitsos said, this layout PS10 condenser array than the results of space occupied by 20%, generating efficiency also increases. "We have done all the work of numerical optimization, and finally return to natural law. This will give us great shock".
Although this discovery is based on computer simulations of basis, but Mitsos very sure it is correct. "The future need to implement thing is to need a like PS10 that cost millions of CSP power station, it takes a while to construction, so to say, it's not a can completed in the lab experiments." But he wants CSP property developer will use his design, thus in the process of building the save of land use, save money.
