On blog pages Culturology. Ru we rarely write about the achievements of human technical thought. However, the amazing solar station, recently opened in Spain, deserves attention as one of the most interesting and wonderful achievements of mankind. It resembles a giant celestial flower with a pistil burning from the color of the sun - and the most amazing thing is that solar power plant continues to work at any time of the day and in any weather.
Larry Niven's fantasy saga "The Ringworld" described mirror flowers that concentrated Sun rays on their pistil and received the energy necessary for survival. The Gemasolar Power Plant solar station near Seville, Spain works on the same principle. More than 2,600 mirrors installed on an area of 185 hectares collect the rays of the sun on, roughly speaking, a barrel of salt. Nitric acid salts perfectly retain heat and heat reservoirs with water, which turns into steam and turns the turbine.
Gemasolar Power Plant is the first solar station that generates energy at night, all thanks to salt, which slowly cools down at night. No wonder the words salt and sun are consonant! The capacity of the station, the construction of which cost 260 million euros, is 20 megawatts. This is two orders of magnitude less than can be obtained from nuclear power plants, but solar energy does not harm the environment and excludes environmental disasters. To obtain the same energy by burning fuel, 30,000 tons of carbon dioxide would have to be emitted into the atmosphere annually! Gemasolar Power Plant is the largest and perhaps the most beautiful plant of its type in Europe.
Solar station, opened in early October 2011, is still operating at 70% of its capacity, but its creators, Torresol Energy and the Arab investor Masdar, expect to reach full speed in 2012. The weather in Seville itself, where it is almost always sunny, will help them in this. And even in the quiet twilight of the nights from Seville to Grenada, now there will be no ringing of swords, but the quiet hiss of salt heated by the sun.

Not only political leaders and renowned figures of science and art - on the streets of cities now more and more other sculptures appear, whose purpose is to entertain, surprise, amuse, and sometimes make one think.

So, Grover Schreer says that the top macro photo he got only from the 25th time
Candle Sculptures by Urs Fischer
In general, sculptures are made of some kind of strong material so that they serve for the benefit of art for years, decades, centuries. But, at the same time, many sculptors understand that everything flows, everything changes. Probably, Urs Fischer understands this best of all, who presented at the Venice Biennale 2011 a series of sculptures, which are essentially huge candles, the wick of which was set on fire exactly on the opening day of the exhibition
