It was inaugurated in 2014 as the largest solar thermal energy plant in the world. Will close after setting fire to birds

The huge Ivanpah thermosolar energy plant, opened in 2014 in the Mojave desert, will close after just 11 years of operation. An accelerated end for its history of technical, economic and environmental problems. Context. The thermal concentration energy, once considered one of the most avant -garde technologies for clean electricity generation, is not going through its best moment. Especially in Nevada, where Crescent Dunes fiasco was already very popular. The concentration thermoso use thousands of mirrors, or “heliosteats”, which follow the trajectory of the sun to concentrate its light on central towers. In these towers, extreme heat is used to heat water and produce steam, which drives turbines connected to electric generators. The Ivanpah case. The Ivanpah plant was built with an investment of 1.6 billion dollars in loans from the United States Department of Energy and long -term contracts for important electrical companies. It was the world’s largest solar thermal energy Until the inauguration of Port Augusta In Australia. 11 years after its inauguration, the huge thermosolar has begun to close by not fulfilling its initial expectations. The lack of profitability condemned her. A succession of failures and complaints from environmental groups for their impact on wildlife accelerated their end. A complex technology. One of the main problems has been the difficulty of maintaining mirrors aligned precisely. Technology, which requires an exact monitoring of the sun, has proven unstable and unreliable in practice, says a CNN report. The maintenance of the complex mechanisms and the management of the turbines in turn generate high operating costs, which has made concentration thermosar loses competitiveness compared to other renewable technologies, especially photovoltaic solar, whose prices have collapsed. A Bird Incinerate Machine. Criticisms are not limited to technical aspects. The Ivanpah plant has been questioned for years for its environmental impact, especially in the wildlife of the desert. Environmental groups denounce the irreparable damage in the habitat of species such as desert turtle. But also The death of birds that are incinerated by intense rays concentrated by mirrors. A second Crescent dunes. The case of Crescent Dunes, also occurred in Nevada, reinforces this image of failure of the thermosolar energy. This project, which was intended to be one of the milestones in energy innovation and storage through molten salts, ended up becoming a multimillionaire waste. Developed By the Spanish group ACSpromised continuous production of electricity, even during the hours without light, thanks to the thermal storage in salts. In practice, Crescent Dunes never managed to deliver the amount of promised energy and ended up breaking due to engineering and management problems. In the shadow of the photovoltaic. In short, the rapid drop in photovoltaic technology and its lower impact on wildlife have obsolete concentration thermos. While solar panels have gained efficiency and reducing their installation and maintenance costs, thermosolar plants have lagged behind in terms of competitiveness, which has led to investors and electrical companies reconsidering their bets in this type of projects.

In 2011, a collector bought in Morocco a meteorite. It has turned out to be a direct test of thermal water on Mars

A black stone that had fallen from the sky was discovered in the Sahara desert by a Saharawi group. Selling to the highest bidder, we have known for a long time that it comes from the Mars cortex, but they have had to spend more than 10 years for scientists to desert one of their best kept secrets. A meteorite called “Black Beauty”. Officially called Northwest Africa 7034, the 320 grams rock was found in 2011 in the Sahara desert, in Western Sahara, and later sold to an American collector in Morocco. Its composition is unique among known Martian meteorites. It contains very old and very young minerals glued to each other, but coincides with what was observed by NASA’s rovers on the surface of Mars, so it was part of the Martian cortex when it detached from the red planet. A time capsule. A Recent study It focuses on a zircon grain found in the meteorite. This zircon has no less than 4,450 million years, which places it in the earliest stages of Martian history. The majority of known meteorites that come from Mars are from later geological periods, so NWA 7034 provides invaluable information on what the surface environment of the red planet was long before becoming what it is today. The meteorite that contains the most water. What makes Black Beauty exceptional is that it houses 10 times more water than other Martian meteorites. It was known that by the interaction of the rock with the water present in the crust of the planet at the time of its formation, but the recent analysis of the zircon with modern microscopy techniques has revealed much more information. The fragment contains iron, aluminum and sodium, unusual elements for a zircon of purely magmatic origin. But it is above all the presence of tiny inclusions of magnetite (iron oxide) that suggests that it crystallized under hydrothermal conditions. That is, in the presence of water at high temperature, and in an oxidizing environment. Ancient hot springs. The magnetite is trapped in zones of the zirch that are not altered by radiation, which indicates that they were formed at the same time as the zirch, and not as a result of subsequent secondary processes, the researchers explain. What the study comes to say is that 4,450 million years ago, during what is known as the pre-ondic period of Mars, there were already hydrothermal conditions in the Martian cortex. The Black Beauty meteorite is a direct proof that Mars had water in its formation stages. Favorable conditions for life. The finding reinforces the hypothesis that Mars had from very early the necessary conditions to house life, or at least some environments suitable for microbial life. That there was life on Mars or that it arrived on earth through a meteorite is still two hypotheses for which we have no evidence. However, that a meteorite of 2011 has given us so much information and reasons to continue investigating demonstrates how important the Martian samples can be that NASA and China want to bring in the coming years.
