Goodby to Solar Panels

Windmills have been the emblem of the Netherlands since ancient times, a tradition that has not been lost to this day. Far from it, the country has become one of the leading wind energy nations in Europe. That said, it is not surprising that this new, smaller, more efficient and quieter wind turbine designed for domestic use comes from there. So, why do you need solar panel at home? You can have a silent wind turbine like this one.

The Netherlands reinvents windmills: an ultra-efficient silent wind turbine
It may be difficult, especially for younger generations, to think of the Netherlands as a heavy industrial powerhouse highly dependent on fossil fuels. However, until the 1970s, pollution due to large numbers of cars and emissions from natural gas and coal-fired power plants fueled a thriving chemical industry.

Air pollution, land scarcity due to its high population density and rising sea levels that threatened to flood its cities led to a sustained effort to decarbonize its economy and diversify its energy sources and industries. Today, the Netherlands is an emblem of innovation in sustainable technologies and policies.

For this transition, one of the key technologies was wind energy, in which today they are one of the main leaders, developing important innovations in this field. The most recent of these innovations is the LIAM F1 UWT, a small and quiet wind turbine for urban use with the capacity to generate between 300 and 2500 kWh, approximately half of the average household consumption.     READ MORE...

Quantum Mechanics in Ultra Cold

There's a hot new BEC in town that has nothing to do with bacon, egg, and cheese. You won't find it at your local bodega, but in the coldest place in New York: the lab of Columbia physicist Sebastian Will, whose experimental group specializes in pushing atoms and molecules to temperatures just fractions of a degree above absolute zero.


Writing in Nature, the Will lab, supported by theoretical collaborator Tijs Karman at Radboud University in the Netherlands, has successfully created a unique quantum state of matter called a Bose-Einstein Condensate (BEC) out of molecules.

Their BEC, cooled to just five nanoKelvin, or about -459.66°F, and stable for a strikingly long two seconds, is made from sodium-cesium molecules. Like water molecules, these molecules are polar, meaning they carry both a positive and a negative charge. 

The imbalanced distribution of electric charge facilitates the long-range interactions that make for the most interesting physics, noted Will.     READ MORE...

Large Structure in Space

The universe is more connected than you might think: In recent years, scientists have used new tools and techniques to map the “cosmic web,” which is made up of intertwined strands of gas structures known as filaments that link galaxies. Now, a team of researchers have identified a new “large-scale structure” in the universe that they call the “Cosmic Vine.”

The researchers hail from numerous universities and institutions across Denmark, Chile, the U.K., and the Netherlands. They published a preprint of their work to the arXiv server on November 8. According to the study, the Cosmic Vine was spotted after poring over data collected by the James Webb Space Telescope (JWST), humanity’s most powerful tool for peering into the far reaches of space and time.  READ MORE...

ASML Makes the Machines that Make the Chips

From the outside it looks like an ordinary corporate building, lots of glass and steel, but this factory in the south of the Netherlands belongs to ASML, and the machines made there are anything but ordinary.


In fact, the technology is so advanced and so much in demand, that ASML has become Europe's most valuable technology firm.


So what is made there?


ASML designs and makes the machines which make computer chips - but not any old computer chips.


ASML machines make the most advanced computer chips and it's the only company in the world with that kind of technology.


This effective monopoly means that exactly how ASML's machines work is subject to some of the most stringent corporate security in the world.


Nevertheless, we were given a tour of its plant, and were guided through the basics.

EUV machine - the extreme ultraviolet light is in purple


Microchips are made by building up complex patterns of transistors, or miniature electrical switches, layer by layer, on a silicon wafer.


They are printed using a lithography system, where light is projected through a blueprint of the pattern of those miniature switches.


The light is then shrunk and focussed using advanced optics and the pattern is etched onto a photosensitive silicon wafer.


That pattern forms the circuitry of a silicon chip, that might end up in a computer, phone or any other electrical device you might care to mention.


The crucial aspect of ASML's most advanced machines is that they can work at tiny scales by generating super fine extreme ultraviolet light - just 13.5 nanometres.  READ MORE...

Tesla's Supercharger Network

After recently expanding its Supercharger pilot program for non-Tesla EV owners, the Supercharger network became the ‘largest 150 kW+ public fast-charging network’ in Europe overnight. It’s quite impressive that Tesla did that basically by just flipping a switch.

Tesla was early in investing in charging infrastructure, which led to the Supercharger becoming the largest global fast-charging network.

The company has been criticized for only providing charging for its own customers when most other networks are for all electric vehicles, but there basically wasn’t any other electric vehicle when Tesla started working on the Supercharger network.

Only lately has the automaker started to work on opening up the network to other EVs.

In November 2021, we saw Tesla take its first step with a pilot program running at 10 Supercharger stations in the Netherlands where non-Tesla EV owners can charge using the Tesla app.

When announcing the new pilot program, Tesla said that it planned to slowly expand it as it tests the user experience for both new non-Tesla EV owners being onboarded on the network and current Tesla owners who are going to see more traffic at those charging stations.

In January, the automaker announced that the program was expanding to more stations in Norway and France, and a month later, the program was expanded to all Supercharger stations in the Netherlands.

Finally, Tesla made its biggest expansion of the pilot program last week by opening many more Supercharger stations in the UK, Spain, Sweden, Belgium, and Austria to all EV owners.

Jeroen van Tilburg, Tesla’s Head of Supercharging in EMEA, had an interesting note about the pilot program. Following the latest expansion, he said that the network of Supercharger stations opened to non-Tesla EV owners in Europe has become the largest network of 150 kW+ public fast-charging stations.  READ MORE...

Germany Roadblock for Russian Sanctions

WARSAW, April 4 (Reuters) - Germany is the main roadblock to imposing tougher sanctions on Russia, Poland's Prime Minister Mateusz Morawiecki said on Monday during a news conference, adding that Hungary was not blocking them.

His comment comes after Prime Minister Viktor Orban won a national election on Sunday after facing criticism over an insufficiently tough stance on Russian aggression in Ukraine.

"We have to see that, regardless of how we approach Hungary, this is the fourth such win and we have to respect democratic elections ... it's Germany that is the main roadblock on sanctions. Hungary is for the sanctions," Morawiecki said.

FRANKFURT/BRUSSELS, March 8 (Reuters) - Russia has warned it may shut off its main Nord Stream gas pipeline to Germany after Berlin halted approval of a second line across the Baltic Sea in response to Russia's invasion of Ukraine. read more

The comment, from Russian deputy prime minister Alexander Novak, reflects escalating tensions that have already sent European gas prices to record levels.

Russia is Germany's top supplier, delivering Europe's largest economy with just under a third of its gas.

Here are key details about Germany's gas sector.

GAS IMPORTS

Germany imported 142 billion cubic metres (bcm) of gas in 2021, down 6.4% from 2020, according to foreign trade statistics office BAFA, which does not identify the origin of imports.

Domestic gas usage was 100 bcm in 2021, utility industry group BDEW said.

Russian piped gas led imports in December at 32% of supply followed by Norway at 20% and Netherlands at 12%, data from Independent Commodity Intelligence Services (ICIS) showed.  READ MORE...

Malta's Cannibis Rules

Malta’s new cannabis rules should serve as a model for other European states of how to end the unnecessary prosecution of low-level drug users and strike a blow against organised crime, according to the minister responsible for the law, Owen Bonnici.

Bonnici, a former justice minister and now minister for equality, research and innovation, said the new law, passed by the Maltese parliament in December 2021, prevented recreational users from being dragged through the courts or tribunal process for possession of small amounts of cannabis.

But it also allows for users and, eventually, non-profit organisations to grow cannabis plants and distribute it to other smokers via cannabis associations, meaning they no longer have to source the drug via the black market and put money into the pockets of international criminal gangs.

Malta’s law allows users to carry seven grams of the drug and store up to 50 grams at home, making it the first EU state to legalise cannabis.

German Chancellor Olof Scholz is in favour of legalisation but the country’s new government has not set a time limit on the reforms.

Although the Netherlands is world-famous for the availability of cannabis, it remains illegal for individuals to sell or possess it and the "coffee shops" that are licensed to sell it have to buy their product in bulk on the black market, incentivising criminals that grow and traffic it.

A number of European states, including Italy, Spain, Belgium and Ireland, have done away with prison sentences for marijuana possession, but in 14 of 28 European states -- including the United Kingdom, France, Germany, Austria -- minor cannabis possession can still lead to jail time.

Even in European states where cannabis has been “decriminalised”, meaning that those caught with small amounts of the product are not be arrested, users still need to buy the drug from dealers.  READ MORE...

Changing the World

Neanderthals left an impact on their environment, having cleared part of a forest in Germany either through their fire use or tool production 125,000 years ago.

This is the conclusion of archaeologists led from Leiden University, who studied an archaeological site called Neumark-Nord some 20 miles west of Leipzig.

Evidence from pollen deposits indicates the flora at the lakeside site changed from closed forest to open vegetation for some 2,000 years of Neanderthal occupation.

The findings, the team said, highlight how modern humans are not the first member of the Homo genus to have exerted a significant influence on their environment.

This is the conclusion of archaeologists led from Leiden University, who studied an archaeological site called Neumark-Nord (pictured) some 20 miles west of Leipzig

NEANDERTHALS AT NEUMARK-NORD
Evidence of Neanderthal activity at Neumark-Nord was first uncovered in 1985, with the site the subject of numerous excavations since.

The hominins are believed to have occupied the lakeside site year-round for some two millennia.

Finds at the site, Dr Roebroeks told the Wall Street Journal, have included 'tens and thousands of stone artefacts, hundreds of thousands of bone fragments [and] the remains of many hundreds of butchered animals.'

Archaeologists have also uncovered abundant traces of fire usage at the site, including charcoal as well as the burnt remains of seeds and wood.

Despite the Neanderthals' significant impact at Neumark-Nord, the ancient lakeside would have been far from what we might recognise as a village settlement.

In fact, Dr Roebroeks explained, the hominins there may have been less mobile but would have still remained hunter–gathers who travelled from place-to-place during the Last Interglacial period.

During the Eemian period (also known as the 'Last Interglacial' and which spanned from 130,000–115,000 years ago) the area around Leipzig was dotted with small lakes left behind after the retreat of the glaciers from the northern European plain.

The withdrawal of the ice sheets also let hominins return to these lands that they had previously abandoned, with excavations at Neumark-Nord since the mid-1980s having turned up evidence of around 2,000 years' worth of Neanderthal occupation.  READ MORE...

Malta Legalizes Cannibus

Malta has become the first EU country to legalise the cultivation and personal use of cannabis.

Adults will be allowed to carry up to seven grams of cannabis, and grow no more than four plants at home.

But smoking it in public or in front of children will be illegal.

Several other nations have similar plans, such as Germany, Luxembourg and Switzerland. Countries like the Netherlands tolerate cannabis use in certain circumstances.

Malta's parliament voted in favour of the reform on Tuesday afternoon, with the bill winning 36 votes in favour and 27 against.

Equality Minister, Owen Bonnici, said the "historic" move would stop small-time cannabis users from facing the criminal justice system, and would "curb drug trafficking by making sure that [users] now have a safe and regularised way from where they can obtain cannabis".

However, Malta's opposition Nationalist Party voted against the change.

In October, its leader Bernard Grech - who initially supported the new law - warned it would "only lead to the strengthening of the illegal market, with organised crime taking advantage," according to The Times.  READ MORE...

A Medieval Solution

In a world of more frequent and more intense flooding, one way to protect against the worst can trace its roots back to the Netherlands, nearly 1,000 years ago.

This July, gorged by days of rain, the Meuse River broke its banks, and the Belgian town of Liège was its victim. Waters the colour of old gravy raced through town, leaving residents floating in canoes as their homes vanished about them. In the city and its province, over 20 died, one man drowning in his basement.

Nor was this corner of Eastern Belgium alone. In nearby Germany, around 200 perished, with journalists describing the flooding as a once-in-a-century event. The financial impact of the disaster was shocking too. Near Liège, a single chocolate factory sustained damages worth around €12m (£10m/$13.5m).

Yet as the mayhem unfolded, one corner of Northern Europe suffered far less. In the Netherlands, the summer flooding was also described as the worst in a century and property damage was severe, but the country survived the floods without a single fatality. There are many reasons for this: quick evacuations, strong dikes and robust communication among them. But what underpins these varied forms of flood defence is an institution: the so-called "water boards" that have protected this waterlogged land for nearly a millennium.  READ MORE...

Neanderthal Man

A recreation of a Neanderthal man’s face is turning heads all over the world – not only for its strong resemblance to our own physiognomy today but also because of the good humor it exudes, as much as 70,000 years after the man died.

What almost everybody instantly recognizes is that this man, nicknamed “Krijn,” who was not even a Homo sapiens, has a magnetic personality that still radiates over the millennia.

As Live Science reports, experts from Kennis & Kennis Reconstructions created the face of the young Neanderthal man from a piece of skull discovered from the North Sea off the coast of the Netherlands twenty years ago.

Face of Neanderthal charms the world
Using what they already knew from the Neanderthals’ sturdy bone structure, the researchers also gleaned information from other skulls that have been found and data regarding their eye, skin, and hair color to help in the recreation of the Neanderthal’s grinning face.

Believed to have lived in Doggerland, which was once dry land but now forms the seabed in the North Sea between the United Kingdom and continental Europe, he died between 50,000 and 70,000 years ago, according to the researchers.  READ MORE...

MC Escher

Maurits Cornelis Escher (Photo right) 17 June 1898 – 27 March 1972 was a Dutch graphic artist who made mathematically inspired woodcuts, lithographs, and mezzotints. Despite wide popular interest, Escher was for long somewhat neglected in the art world, even in his native Netherlands. He was 70 before a retrospective exhibition was held. In the twenty-first century, he became more widely appreciated, with exhibitions across the world.

His work features mathematical objects and operations including impossible objects, explorations of infinity, reflection, symmetry, perspective, truncated and stellated polyhedra, hyperbolic geometry, and tessellations. Although Escher believed he had no mathematical ability, he interacted with the mathematicians George Pólya, Roger Penrose, Harold Coxeter and crystallographer Friedrich Haag, and conducted his own research into tessellation.

Early in his career, he drew inspiration from nature, making studies of insects, landscapes, and plants such as lichens, all of which he used as details in his artworks. He traveled in Italy and Spain, sketching buildings, townscapes, architecture and the tilings of the Alhambra and the Mezquita of Cordoba, and became steadily more interested in their mathematical structure.

Escher's art became well known among scientists and mathematicians, and in popular culture, especially after it was featured by Martin Gardner in his April 1966 Mathematical Games column in Scientific American. Apart from being used in a variety of technical papers, his work has appeared on the covers of many books and albums. He was one of the major inspirations of Douglas Hofstadter's Pulitzer Prize-winning 1979 book Gödel, Escher, Bach.  SOURCE:  Wikipedia
