Tagebau Welzow

Tagebau Welzow

Vor einiger Zeit hatte ich die Gelegenheit im Braunkohle-Tagebau Welzow fotografieren zu können. Als Teil einer geführten Geländewagen-Tour war es möglich in Bereiche vorzudringen, die dem Beobachter von den offiziellen Aussichtspunkten verborgen bleiben. 

Das Betriebsgelände ist nur in Verbindung mit einer gebuchten Tour zugänglich. Dazu gehören auch Jeep-Touren, die von örtlichen Tourismusorganisatoren durchgeführt werden. Im Geländewagen ist es dann relativ problemlos möglich die ansonsten nicht passierbaren Abfahrten hinein in den Tagebau zu meistern. Der Tagebau Welzow fördert täglich 50k Tonnen Braunkohle, die zu 2/3 direkt in das benachbarte Kraftwerk gespeist werden, zu Spitzenzeiten lässt sich die Förderleistung auf 100k Tonnen hochschrauben. Das eigentliche Kohleflötz hat nur eine Mächtigkeit von 10 bis 15 Metern, darüber befindet sich aber das Deckgebirge von 90 bis 150 Metern, das als Abraum erst mal beseitigt werden muss. Dementsprechend groß ist das Abbaugebiet und die darin befindlichen Maschinen.

Aus fotografischer Sicht war es mir primär wichtig die Weitläufigkeit des Abbaugebietes einzufangen. Um eine geeignete Bildwirkung zu erzielen muss ein Bildelement vorhanden sein, über das der Betrachter die tatsächliche Größe einschätzen kann. Geeignet dafür sind Objekte, deren Größe man aus dem Alltag kennt, z.B. ein Bagger, eine Hütte oder eine Schiene. Natürlich eignen sich für diese Art Bilder besonders Weitwinkelobjektive, um möglichst viel von der Landschaft ins Bild zu pressen. Als Nebeneffekt nimmt auch der Himmel entsprechend viel Platz ein und verstärkt bei geeigneter Textur noch den Eindruck der Tiefe im Bild. Geeignete Textur bedeutet in dem Fall, dass er nicht einfach einfarbig blau oder grau sein sollte, sondern Wolken vorhanden sein müssen, die sich möglichst gut einzeln abgrenzen. Das Beispielbild wurde mit dem 14mm Walimex f2.8 gemacht und liefert am Vollformat schon einen enorm großen Bildausschnitt. Der orange Versorgungszug übernimmt die Rolle des Maßstabsgebers, dem Betrachter wird auch ohne die exakte Größe des Zuges zu kennen sofort klar, wie riesig die Flächen sein müssen im Bild. Unterstützt wird dieser Effekt natürlich auch von der Linienführung: Alle Grabenwände laufen auf einen gemeinsamen Fluchtpunkt am Horizont zu, der Betrachter wird quasi gezwungen dem Graben in der Mitte zu folgen.

Sehr interessant sind im Tagebau auch die verschiedenen Farben und Strukturen, die entstehen. Der Abraum besteht weitestgehend aus Sand, der durch den Absetzer wieder aufgeschichtet wird. Entsprechend anfällig ist die so neu geschaffene Landschaft für Erosion. Insbesondere Regen schwemmt viel Boden aus und erzeugt so sehr interessante Sandformationen. Der Sand hat keine einheitliche Farbe, da auch er in verschiedenen Epochen der Erdgeschichte abgelagert wurde (man darf nicht vergessen, dass diese gigantischen Bagger in Sekunden Millionen Jahre Erdgeschichte umgraben). Spannend sind auch die Farben, die durch den sogenannten "Lausitzer Ocker" gebildet werden. Leider handelt es sich dabei eigentlich um ein massives Umweltproblem, das in der Umgebung von Tagebaugebieten zur Bedrohung für Pflanzen und Tiere geworden ist.

Die Lichtverhältnisse waren leider nicht optimal. Alle Bilder sind in der Mittagszeit entstanden bei durchgehend grauem Himmel. Entsprechend flau sahen viele der Bilder out of cam aus. Mit der entsprechenden Kontrastanpassung in Lightroom ließ sich aber der Dynamikumfang der Bilder deutlich erhöhen, so dass im Himmel wieder einzelne Wolken erkennbar waren und die wenigen Farben im Tagebau wieder etwas mehr zu leuchten begannen. Der Workflow dabei ist für mich immer recht ähnlich. Die Tiefen/Lichter-Regler werden genutzt, um möglichst viel Restinformation aus den RAWs rauszuholen, nicht selten werden beide Regler fast bis zum Anschlag (Tiefen hoch, Lichter runter) gezogen. Um dann das Histogramm wieder zu strecken, nutze ich die Regler für weiß und schwarz und achte darauf, dass keine Bereiche ausbrennen oder unterbelichtet werden. Etwas Klarheit bringt dann noch den nötigen Mikrokontrast und verstärkt die Farben etwas im Bild.

    Josh Giddey hits halfcourt buzzer-beater over LeBron James to cap wild finale as the Bulls stun the Lakers
    quickswap
    Josh Giddey hit a game-winning, halfcourt buzzer-beater over LeBron James as the Chicago Bulls stunned the Los Angeles Lakers in one of the wildest endings to an NBA game you are ever likely to see.

    Trailing 115-110 with 12.6 seconds remaining, Giddey’s inbound pass found Nikola Vucevic, who pushed the ball to a wide-open Patrick Williams for a corner three-pointer.

    James then fluffed the Lakers inbound pass from the baseline, allowing Giddey to steal the ball and find Coby White for a second Bulls triple in quick succession to put Chicago up 116-115 with 6.1 seconds remaining.
    Austin Reaves then made a driving layup to put the Lakers ahead 117-116 with 3.3 seconds left, but the game wasn’t done yet.

    With no timeouts remaining, Giddey inbounded the ball to Williams from the baseline, got the pass back, took one dribble and launched a shot from beyond halfcourt.

    Supporters in the stands seemed frozen in anticipation as the ball sailed through the air, and the United Center then erupted as it fell through the net. After the dramatic win, Giddey found himself being swarmed by his teammates.

    “Special moment to do it with these guys, this team,” Giddey said, per ESPN. “We’ve shown over the last month to six weeks that we can beat anybody. The way we play the game, I think it wears people down.

    “We get up and down. We run. We put heat on them to get back. A lot of veteran teams don’t particularly want to get back and play in transition.”

    Giddey later told the Bulls broadcast that he’d “never made a game-winner before.”

    The ending capped an incredible couple of games for the Lakers, who had themselves won their last game against the Indiana Pacers on Wednesday with a buzzer-beating tip-in from James.

    “You have a government that is reckless about what is going to happen to Guyana,” said Melinda Janki, an international lawyer in Guyana who is handling several lawsuits against Exxon. It’s pursuing “a supposed course of development that is actually backward and destructive,” she told CNN.

    And while plenty of Guyanese people welcome the new oil industry, some say Guyana’s startling economic statistics do not reflect a real-world prosperity for ordinary people, many of whom are struggling with the higher prices accompanying the oil boom. Inflation rose 6.6% in 2023, with prices of some foods shooting up much more rapidly.

    “Since the oil extraction began in Guyana, we have noticed that our cost of living has gone sky high,” said Wintress White, of Red Thread, a non-profit that focuses on improving living conditions for Guyanese women. “The money is not trickling down to the masses,” she told CNN.

    CNN contacted President Ali, the Ministry of Natural Resources and the Ministry of Finance for comment but received no response.
    Guyana, a former Dutch then British colony which gained independence in 1966, is one of only a handful of countries that is a “carbon sink,” meaning it stores more planet-heating pollution than it produces. This is due to its vast rainforest; trees remove carbon dioxide from the atmosphere as they grow.

    The country has protected its biodiversity where others have destroyed theirs, President Ali said in a BBC interview last year. In 2009, the country signed an agreement with Norway, which promised Guyana more than $250 million to preserve its 18.5 million hectares, or nearly 46 million acres, of forests.

    Ali insists the country can balance climate leadership and fossil fuel exploitation. The new oil wealth will allow Guayana to develop, including building climate adaptations such as sea walls, he has said. He has also pointed to the continued failures of wealthy countries, already grown rich on their own fossil fuels, to help poorer countries with climate finance.

    But there are concerns Guyana could fall victim to the “resource curse,” in which vast, new wealth ?can actually make life worse for those who live there.

    Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
    safepal
    In the 1931 movie “Frankenstein,” Dr. Henry Frankenstein howling his triumph was an electrifying moment in more ways than one. As massive bolts of lightning and energy crackled, Frankenstein’s monster stirred on a laboratory table, its corpse brought to life by the power of electricity.

    Electrical energy may also have sparked the beginnings of life on Earth billions of years ago, though with a bit less scenery-chewing than that classic film scene.

    Earth is around 4.5 billion years old, and the oldest direct fossil evidence of ancient life — stromatolites, or microscopic organisms preserved in layers known as microbial mats — is about 3.5 billion years old. However, some scientists suspect life originated even earlier, emerging from accumulated organic molecules in primitive bodies of water, a mixture sometimes referred to as primordial soup.

    But where did that organic material come from in the first place? Researchers decades ago proposed that lightning caused chemical reactions in ancient Earth’s oceans and spontaneously produced the organic molecules.

    Now, new research published March 14 in the journal Science Advances suggests that fizzes of barely visible “microlightning,” generated between charged droplets of water mist, could have been potent enough to cook up amino acids from inorganic material. Amino acids — organic molecules that combine to form proteins — are life’s most basic building blocks and would have been the first step toward the evolution of life.

    Здравствуйте!
    На выходных я решил посетить город Балашиха и был приятно удивлён его атмосферой. Я прогулялся по парку культуры и отдыха, наслаждаясь свежим воздухом и зелеными насаждениями. Вечером я заглянул в один из местных кафе, где попробовал вкусные блюда русской кухни. Этот день в Балашихе стал для меня отличным способом отвлечься от городской суеты и насладиться спокойствием.
    Решил провести вечер в компании, поэтому воспользовался сайтом эскорт-услуг и пообщался с приятной девушкой.

    A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
    kyberswap
    Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny, rainforested country.

    It was one of the most spectacular oil discoveries of recent decades. By 2019, Exxon and its partners, US oil company Hess and China-headquartered CNOOC, had started producing the fossil fuel.? They now pump around 650,000 barrels of oil a day, with plans to more than double this to 1.3 million by 2027.

    Guyana now has the world’s highest expected oil production growth through 2035.

    This country — sandwiched between Brazil, Venezuela and Suriname — has been hailed as a climate champion for the lush, well-preserved forests that carpet nearly 90% of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate.

    While the government says environmental protection and an oil industry can go hand-in-hand, and low-income countries must be allowed to exploit their own resources, critics say it’s a dangerous path in a warming world, and the benefits may ultimately skew toward Exxon — not Guyana.
    Since Exxon’s transformative discovery, Guyana’s government has tightly embraced oil as a route to prosperity. In December 2019, then-President David Granger said in a speech, “petroleum resources will be utilized to provide the good life for all … Every Guyanese will benefit.”

    It’s a narrative that has continued under current President Mohamed Irfaan Ali, who says new oil wealth will allow Guyana to develop better infrastructure, healthcare and climate adaptation.

    Mindful wellness challenges
    If you’re the type of person who thrives on challenges and pushing your limits, this doesn’t mean you need to shy away from wellness challenges altogether. But before diving in, take a step back and ask yourself if you’re pursuing the challenge for the right reasons, McGregor said.
    velodrome finance
    Some people want to try these challenges because they believe something is missing from their life, and they’re looking to attain “worth” or receive validation, McGregor noted.

    A good way to assess your motivation is by considering whether the challenge will benefit your health or if it’s about showcasing your accomplishments on social media or some other reason.

    Before trying any new trend, make sure you have the foundation to handle it and be aware of any potential risks, McGregor said.

    For casual runners, this might mean signing up for a 5K but building your endurance gradually while incorporating other strength training exercises into your routine. For more intense challenges, such as a marathon, McGregor encourages people to consult with professionals or a coach who can monitor your progress and condition along the way.

    Focusing on sustainable habits
    Both McGregor and Curran emphasize the importance of fostering sustainable health habits before embarking on more extreme challenges.

    Rather than chasing the idea of being “healthy,” McGregor suggests focusing on actual healthful behaviors and starting small.

    If you’re a highly sedentary person and want to add more movement to your day, try doing lunges while brushing your teeth or taking short walks throughout your typical routine.

    Americans Brittany and Blake Bowen had never even been to Ecuador when in 2021 they decided to move to the South American country with their four children.

    Tired of “long commutes and never enough money” in the US, the Bowens say they love their new Ecuadorian life. “We hope that maybe we’ll have grandkids here one day.”

    Erik and Erin Eagleman moved to Switzerland from Wisconsin with their three children in 2023.

    “It feels safe here,” they tell CNN of their new outdoorsy lifestyle in Basel, close to the borders with France and Germany. Their youngest daughter even walks to elementary school by herself.

    For adventures with your own family, be it weekend breaks or something longer-term, our partners at CNN Underscored, a product review and recommendations guide owned by CNN, have this roundup of the best kids’ luggage sets and bags.

    For close to 100 years, Michelin stars have been a sign of culinary excellence, awarded only to the great and good.

    Georges Blanc, the world’s longest-standing Michelin-starred restaurant, has boasted a three-star rating since 1981, but this month the Michelin guide announced that the restaurant in eastern France was losing a star.

    More culinary reputations were enhanced this week, when Asia’s 50 best restaurants for 2025 were revealed. The winner was a Bangkok restaurant which is no stranger to garlands, while second and third place went to two Hong Kong eateries.

    You don’t need to go to a heaving metropolis for excellent food, however. A 200-year-old cottage on a remote stretch of Ireland’s Atlantic coast has been given a Michelin star. At the time of awarding, Michelin called it “surely the most rural” of its newest winners.

    Water and life
    stargate finance
    Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.

    Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.

    “Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”

    However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids and extreme pressure.

    Researchers identified salt minerals in the Bennu samples that were deposited as a result of brine evaporation from the asteroid’s parent body. In particular, they found a number of sodium salts, such as the needles of hydrated sodium carbonate highlighted in purple in this false-colored image – salts that could easily have been compromised if the samples had been exposed to water in Earth’s atmosphere.

    Yet another hypothesis suggests that organic molecules didn’t originate on Earth at all. Rather, they formed in space and were carried here by comets or fragments of asteroids, a process known as panspermia.

    “We still don’t know the answer to this question,” Zare said. “But I think we’re closer to understanding something more about what could have happened.”

    Though the details of life’s origins on Earth may never be fully explained, “this study provides another avenue for the formation of molecules crucial to the origin of life,” Williams said. “Water is a ubiquitous aspect of our world, giving rise to the moniker ‘Blue Marble’ to describe the Earth from space. Perhaps the falling of water, the most crucial element that sustains us, also played a greater role in the origin of life on Earth than we previously recognized.”
