Wearing the Future: How Solar Fashion is Powering a Sustainable Tomorrow
The fashion industry is transforming significantly, integrating sustainability and technology to create innovative solutions. One of the most groundbreaking developments is solar-powered clothing—textiles embedded with solar panels that can capture sunlight and convert it into usable electricity. This innovation not only enhances the functionality of garments but also contributes to sustainable energy use, reducing dependence on conventional power sources. Imagine a jacket that charges your phone on the go or a dress that glows at night using stored solar energy. These advancements are not futuristic concepts but are rapidly becoming a reality.
What is Solar Fashion?
Solar fashion refers to garments equipped with thin, flexible photovoltaic (PV) cells that absorb sunlight and convert it into electrical energy. This energy is either stored in small, built-in batteries or used immediately to power small devices like smartphones, smartwatches, or wearable medical equipment. By combining fashion with renewable energy, solar textiles are redefining how people think about clothing and its role in everyday life.
Early solar garments were bulky and impractical due to the rigidity of traditional solar panels. However, with advancements in materials science, newer versions of solar fabrics are lightweight, flexible, and seamlessly integrated into clothing. This makes them more wearable, stylish, and energy-efficient, turning solar fashion into a practical solution for modern consumers.
The Evolution of Solar-Powered Clothing
Initially, solar-powered fashion was seen as more of a novelty than a functional innovation. Early designs were often uncomfortable, stiff, and not very energy efficient. However, designers and engineers have since collaborated to make solar fashion both stylish and practical. Some of the most notable innovations include:
1. Pauline van Dongen's Solar Shirt : Dutch designer Pauline van Dongen has been at the forefront of wearable solar technology. Her Solar Shirt incorporates ultra-thin, flexible solar panels into the fabric, allowing it to harness energy while maintaining a stylish and comfortable fit. The stored energy can charge small electronic devices, making it a practical and fashionable innovation.
2. Tommy Hilfiger's Solar Jacket : Tommy Hilfiger, in collaboration with Pavilion, launched a solar-powered jacket with detachable solar panels. These panels collect solar energy, store it in a built-in power bank, and allow wearers to charge their electronic devices conveniently. The jacket combines aesthetics with functionality, making it appealing to fashion-conscious consumers.
3. Vollebak's Solar-Charged Jacket : The Vollebak Solar Charged Jacket absorbs sunlight during the day and glows in the dark at night. Unlike traditional solar clothing, which primarily focuses on energy storage, this jacket also provides a striking visual effect, making it ideal for outdoor sports and adventure activities.
How Solar Textiles Work
Photovoltaic (PV) cells, commonly found in solar panels, are constructed from semiconducting materials like silicon. When sunlight strikes these materials, it excites electrons, causing them to flow and generate an electric current. In solar textiles, researchers embed ultra-thin versions of these PV cells into threads or coat fibres with solar-active compounds. Some opt for dye-sensitised or organic solar cells, which are lightweight, flexible, and easier to integrate into fabrics.
This innovation enables textiles to function like solar panels without the rigidity. Energy harvested during the day can be stored in mini batteries or supercapacitors, allowing the garment to power gadgets even after sunset. The key lies in creating a balance between energy efficiency, comfort, and durability—areas where research is rapidly advancing.
Colour-Changing Fabrics in Solar Fashion
An exciting innovation in solar textiles is the incorporation of colour-changing fabrics. These textiles use special dyes that react to sunlight or temperature changes, allowing garments to shift hues throughout the day. When combined with solar energy, these fabrics enhance both fashion and functionality.
UV-sensitive textiles change colour when exposed to sunlight, offering a visual indicator of UV exposure levels.
Temperature-sensitive fabrics adjust their colour based on environmental conditions, creating dynamic and interactive clothing options.
These technologies add a creative and customisable element to clothing, making solar fashion not only sustainable but also highly engaging for consumers.
The Benefits of Solar Fashion
Integrating solar energy into textiles offers several key benefits, both environmentally and practically:
1. Sustainability and Environmental Impact : Solar-powered clothing reduce dependence on fossil fuels and conventional electricity sources, contributing to a cleaner environment. The fashion industry is a significant polluter, and adopting solar textiles can help reduce carbon emissions and energy waste.

Europe's growing fear: How Trump might use US tech dominance against it
When President Donald Trump issued an executive order in February against the chief prosecutor of the International Criminal Court for investigating Israel for war crimes, Microsoft was suddenly thrust into the middle of a geopolitical fight. For years, Microsoft had supplied the court — which is based in The Hague in the Netherlands and investigates and prosecutes human rights breaches, genocides and other crimes of international concern — with digital services such as email. Trump's order abruptly threw that relationship into disarray by barring U.S. companies from providing services to the prosecutor, Karim Khan. Soon after, Microsoft, which is based in Redmond, Washington, helped turn off Khan's ICC email account, freezing him out of communications with colleagues just a few months after the court had issued an arrest warrant for Prime Minister Benjamin Netanyahu of Israel for his country's actions in the Gaza Strip. Microsoft's swift compliance with Trump's order, reported earlier by The Associated Press, shocked policymakers across Europe. It was a wake-up call for a problem far bigger than just one email account, stoking fears that the Trump administration would leverage America's tech dominance to penalize opponents, even in allied countries like the Netherlands. 'The ICC showed this can happen,' said Bart Groothuis, a former head of cybersecurity for the Dutch Ministry of Defense who is now a member of the European Parliament. 'It's not just fantasy.' Groothuis once supported U.S. tech firms but has done a '180-degree flip-flop,' he said. 'We have to take steps as Europe to do more for our sovereignty.' Some at the ICC are now using Proton, a Swiss company that provides encrypted email services, three people with knowledge of the communications said. Microsoft said the decision to suspend Khan's email had been made in consultation with the ICC. The company said it had since enacted policy changes that had been in the works before the episode to protect customers in similar geopolitical situations in the future. When the Trump administration sanctioned four additional ICC judges this month, their email accounts were not suspended, the company said. Brad Smith, Microsoft's president, said concerns raised by the ICC episode were a 'symptom' of a larger erosion of trust between the United States and Europe. 'The ICC issue added fuel to a fire that was already burning,' he said. Khan has been on leave from the ICC since last month, pending a sexual misconduct investigation. He has denied the allegations. An ICC spokesperson said it was taking steps to 'mitigate risks which may affect the court's personnel' and 'taking extensive measures to ensure the continuity of all relevant operations and services in the face of sanctions.' The episode has set off alarms across Europe about how dependent European governments, businesses and citizens are on U.S. tech companies like Microsoft for essential digital infrastructure — and how hard it will be to disentangle themselves. Concerns about how else Trump might leverage technology for political advantage has jump-started efforts across the region to develop alternatives. Casper Klynge, a former Danish and European Union diplomat who worked for Microsoft, said the episode was in many ways the 'smoking gun that many Europeans had been looking for.' 'If the U.S. administration goes after certain organizations, countries or individuals, the fear is American companies are obligated to comply,' said Klynge, who now works for a cybersecurity company. 'It's had a profound impact.' The tech debate adds to an increasingly fractious U.S.-European relationship over trade, tariffs and the war in Ukraine. Trump and Vice President JD Vance have criticized how Europe regulates U.S. tech companies, and U.S. officials have made digital oversight and taxation part of ongoing trade negotiations. European regulators have argued that they need to be able to police the biggest digital platforms in their own countries without worrying that they will face political pressure and punishment from a foreign government. 'If we don't build adequate capacity within Europe, then we won't be able to make political choices anymore,' said Alexandra Geese, a member of the European Parliament. Since Edward Snowden's leak of scores of documents in 2013 detailing widespread U.S. surveillance of digital communications, Europeans have sought to diminish their reliance on U.S. tech. Lawmakers and regulators have targeted Apple, Meta, Google and others for anticompetitive business practices, privacy-invading services, and the spread of disinformation and other divisive content. Yet without viable alternatives, institutions across the region have turned to U.S. digital services. Amazon, Google, Microsoft and other U.S. firms control more than 70% of the cloud computing market in Europe, which is the essential way for storing files, retrieving data and running other programs, according to Synergy Research Group. The ICC has been a longtime customer of Microsoft, which provides the court with services including the Office software suite and software for evidence analysis and file storage, according to an ICC lawyer who declined to be identified discussing internal procedures. Microsoft has also provided cybersecurity software to help the court withstand digital attacks from adversaries like Russia, which is being investigated for war crimes in Ukraine. In February, after Trump issued penalties against Khan, Microsoft met with ICC officials to decide how to respond. They concluded that Microsoft's broader work for the court could continue but that Khan's email should be suspended. He switched his correspondence to another email account, said a person who has communicated with him. Sara Elizabeth Dill, a lawyer who specializes in sanctions compliance, said the Trump administration was increasingly using sanctions and executive orders to target international institutions, universities and other organizations, forcing companies to make hard choices about how to comply. 'This is a quagmire and places these corporations in a very difficult position,' she said. How tech companies with global services respond is especially important, she added, 'as the broad repercussions are what people and organizations are primarily worried about.' Microsoft and other U.S. companies have sought to reassure European customers. On Monday, Microsoft CEO Satya Nadella visited the Netherlands and announced new 'sovereign solutions' for European institutions, including legal and data security protections for 'a time of geopolitical volatility.' Amazon and Google have also announced policies aimed at European customers. Still, many institutions are exploring alternatives. In the Netherlands, the 'subject of digital autonomy and sovereignty has the full attention of the central government,' Eddie van Marum, the state secretary of digitalization in the Ministry of Interior Affairs, said in a statement. The country is working with European providers on new solutions, he said. In Denmark, the digital ministry is testing alternatives to Microsoft Office. In Germany, the northern state of Schleswig-Holstein is also taking steps to cut its use of Microsoft. In the European Union, officials have announced plans to spend billions of euros on new artificial intelligence data centers and cloud computing infrastructure that rely less on U.S. companies. Groothuis, the Dutch member of the European Parliament, said lawmakers in Brussels were discussing policy changes that would encourage governments to favor buying tech services from EU-based companies. 'The situation is not tenable, and we see a big push from European governments to become more independent and more resilient,' said Andy Yen, CEO of Proton. European tech companies see an opportunity to win customers from their U.S. rivals. Cloud service providers like Intermax Group, based in the Netherlands, and Exoscale, based in Switzerland, said they had seen a jump in new business. 'A few years ago, everyone was saying, 'They're our trusted partners,'' Ludo Baauw, Intermax's CEO, said of U.S. tech companies. 'There's been a radical change.'

Why and how Europe's growing fear of Donald Trump is bad news for Microsoft, Google, Apple and others
European governments and institutions are accelerating efforts to reduce their dependence on American tech giants after President Trump used executive powers to force Microsoft to suspend the email account of an International Criminal Court prosecutor investigating Israel for war crimes, according to a New York Times report. The February incident involving ICC prosecutor Karim Khan has become a watershed moment for European policymakers, who now view America's tech dominance as a potential weapon that could be wielded against them even in allied nations like the Netherlands.

Is it a moon? Is it a dwarf planet? Well, it's Charon, and it could well be both!
Charon's discovery The story of Charon's discovery takes us back to 1978 – a time when even astronomers were still thinking that Pluto was a planet. Little was known about Pluto and its system, but all that was about to change in the decades that followed. On the morning of June 22, American astronomer James Christy already had his head whirling around. If you were under the impression that he was zeroing in on the solution for an astronomical problem, you couldn't be further from the truth. Christy was sharpening his plans to move his house, getting ready for a week's leave from the U.S. Naval Observatory in Flagstaff, Arizona – his workplace. It was under these circumstances that Robert Harrington, his boss, handed him a set of six photographs of Pluto. Christy and Harrington were looking to refine Pluto's orbit around the sun – a journey that takes Pluto 248 Earth years. Pluto's average distance from the sun is 5.9 billion km. The technology available at that time meant that even the best photographs of it hardly revealed anything. What's more, these six images – acquired in pairs over three nights in the month between April 13 and May 12 – were labelled as 'defective.' Odd blobs The reason why these pictures were labelled thus owed to the fact that they revealed Pluto to be oddly elongated. Viewing them under a microscope, Christy noticed that the fuzzy blob that was to be Pluto stretched in a northern direction in two of those pairs, while the final pair showed a southward direction. The defects were attributed either to atmospheric distortion or improper optical alignment in the telescope used for observations. After ruling out an explosion on Pluto as an unlikely explanation – especially as it lasted a month – Christy searched for other plausible reasons. There was a chance that Pluto itself was irregular in shape. Or could there be an unseen moon, even though one of his former professors, celebrated Dutch-American astronomer Gerard Kuiper, had searched for exactly the same decades earlier without any success? When Christy went over to the archives to check through older plates from 1965 onwards, there it was... the same elongation. What's more, all these images had also been dismissed as defective on every occasion. Correct conclusions Christy and Harrington, however, realised that they were onto something. By reviewing all the images with the elongations, they were able to state that the bulge occurred with a predictable frequency. This frequency of the unseen moon's orbital period – 6.4 Earth days – matched with what astronomers believed to be Pluto's rotational period, suggesting a synchronously locked binary system. The duo ruled out other possible reasons for the bulge and concluded correctly that Pluto had another companion at a distance of 19,640 km. The discovery of 'S/1978 P1' was announced by them through the International Astronomical Union (IAU) on July 7 and their findings were published in the Astronomical Journal. What started out as reviewing six defective images, served as the seeds for a whole new discovery. As Christy himself once pointed out, 'Discovery is where the scientist touches nature in its least predictable aspect.' What's in a name? As the discoverer, Christy wanted to exercise his rights for naming Pluto's companion. And he had his mind set on naming it after his wife. The Naval Observatory he worked for had suggested the name Persephone, the wife of Hades. Hades, the god of the underworld in Greek mythology, was the equivalent of the Roman god Pluto after which it is named. As luck would have it, Christy came across a reference to Charon, a boatman who ferried the dead across a river in the underworld to Hades. Charon's close mythical association with Hades, or Pluto, made it a great option for the newly discovered astronomical object. It was the perfect option for Christy as his wife's name was Charlene. In addition to sharing the first four letters, 'Char' was the nickname that friends and family used to call his wife. Just like how protons and electrons have the 'on' suffix, Christy saw Charon as 'Char' with the suffix 'on' and submitted his name. Eclipses and occultations By the time this name was accepted by IAU in January 1986, Pluto and Charon had a series of mutual eclipses and occultations. Studying them enabled astronomers in general, and Harrington in particular, to confirm the existence of Charon as he observed the eclipses and occultations to occur as predicted. Observing Pluto and Charon in this manner also enabled astronomers to arrive at Charon's diameter to be about 1,200 km, while also arriving at better estimates of the size and mass of Pluto. From a small dot in a photograph, Charon had become much much more – almost a world in its own right. It definitely meant the world to Christy in more ways than one, as he was also able to gift his wife the moon! Charlene Christy probably summed it the best when she said 'A lot of husbands promise their wives the moon, but Jim actually delivered.' Charon fact sheet Most of what we know about Charon, or even Pluto for that matter, is thanks to NASA's New Horizons mission. Approved in 2001 as the first flyby of Pluto and its largest moon Charon, it was launched in January 2006. This was months before IAU's decision in August the same year to demote Pluto's designation from a planet to a dwarf planet. Despite the fact that Pluto was plutoed, the mission went on, providing us invaluable information. Before New Horizons' closest approach to Pluto on July 14, 2015, the spacecraft captured plenty of images of Charon. While the images revealed a striking reddish north (top) polar region, Charon's colour palette wasn't as diverse as Pluto's. The origins of this red colouration is a mystery for now and no other icy object in the solar system sports a similar feature. Charon is 1,214 km across and is at a distance of 19,640 km from Pluto. As Pluto's equatorial diameter is about 2,377 km, Charon is nearly half the size of Pluto. This makes it the largest known satellite relative to its parent body for most astronomers. It is this same size, however, that forces other astronomers to consider Pluto and Charon as a double dwarf planet system. Charon's orbit takes 6.4 Earth days to go around Pluto. Charon neither rises or sets, however, but instead hovers near the same region on Pluto's surface. The same surfaces of Charon and Pluto always face each other due to a phenomenon called mutual tidal locking.
