This Briefcase-Sized Portable Desalination Unit is Easily Transportable

0

It may be a small briefcase for one person, but it could become a major desalination leap for mankind. It is the outcome of a decade of research by a group of MIT researchers and brings together several novel technologies in a pioneering miniature format. In addition to its portability, it offers several advantages, such as the absence of filters and its low energy consumption. Will it be the first step towards pocket-sized and, above all, sustainable desalination?

In this article you can read about:

MIT’s portable desalination unit

The innovative MIT device weighs less than twenty pounds but meets the World Health Organization‘s drinking water standards by reducing solid particles in water to less than one-tenth. The first version of the desalination case can make up to 0.3 liters of water drinkable per hour with just twenty watts of energy. Additionally, it is designed so anyone without technical knowledge can use it in minutes.

All the user has to do is press a button and once the particles in the water have been reduced to safe levels, they will receive a notification. In fact, the researchers have created a mobile app that allows the unit to be controlled wirelessly and obtain real-time information on water salinity and energy consumption. Regarding the latter, the team claims that the machine has the energy consumption of a cell phone charger. But how did they achieve this?   

A solar-powered, filter-free technology    

MIT’s portable desalination system integrates several innovative technologies, the most important of which is called ICP (Ion Concentration Polarization). Typically, large-scale desalination plants use a process called reverse osmosis. Although the most efficient for large-scale desalination plants, this technology requires the application of pressure, which increases the energy requirements and rules it out for a portable desalination plant. Hence, the team applied the ICP system they developed ten years ago.

ICP essentially dispenses with filters and relies on membranes to which an electric field is applied. These membranes are placed above and below a stream of water so that they repel positively or negatively charged particles as they pass through. These particles include salt molecules, bacteria, and viruses, among others. The particles are then transferred to the second stream of water expelled from the circuit. This entire process can be carried out with a low-pressure pump.

However, the ICP does not remove all salt ions, so a second electrodialysis process is required to remove them completely. Both modules can be integrated into a unit small enough to fit into a briefcase.

into a briefcase.

The absence of filters reduces maintenance and cleaning requirements so that the unit can remain operational for a longer period without needing servicing or replacement. In addition, a small solar panel can power both the low-pressure pump and the ICP and electrodialysis modules. All this allows the equipment to be fully portable and can be used in remote areas without regular access to electricity or in humanitarian catastrophe situations. In short, to improve people’s lives.

A successful real-world demonstration

After integrating the said technologies and conducting various laboratory tests, the researchers went out into the real world to test their portable desalination unit. The first test took place at Carston Beach in the U.S. city of Boston. There, they placed the feeding tube into the seawater, filling a glass of clean drinking water within half an hour.

The researchers themselves were surprised that it worked the first time. The goal now is to improve the efficiency and performance of the technology, reduce the cost of materials and transfer all this to a company that can commercialize the water purification case. MIT’s portable desalination unit will also have to process water with high turbidity levels without contamination impairing its functionality. If you want to know more about this technology, here is a video from the developers.

Iraq is experiencing a water crisis as its rivers dry up, posing a threat to the nation’s agriculture sector

0

Farmers and experts warn Iraq’s historic rivers are vanishing, threatening survival, identity and stability.

Iraq, once known as Mesopotamia, the “Land of the Two Rivers”, is facing its worst water crisis in living memory. The Tigris and Euphrates — lifelines of agriculture and civilisation for millennia — are running dry. Climate change, upstream dams and decades of mismanagement have turned fertile land into dust, forcing families from their homes and threatening national stability. Talk to Al Jazeera travels to southern Iraq to hear from farmers, environmentalists and officials about a crisis that could decide the country’s future.

From Strengthening NATO’s Incident Response to Leading the Cyber Defense Sector: My Journey to CEO

0

In the age of decentralized warfare, conflicts are no longer bound by geography. A drone launched from a garage, or a malicious line of code can hit as hard as a missile, though it can be deployed far from any conventional front lines. Nation states must now defend everywhere at once, and critical infrastructure has well and truly become a major target. 

As the face of warfare changes completely, Western governments must adapt to keep up, reevaluate what constitutes “defense,” and prioritize the importance of cybersecurity innovation. At the NATO Summit earlier this summer, the alliance took an essential first step towards building this modern defense landscape. It agreed to boost defense spending towards 5% of GDP and reiterated NATO members’ Article 5 commitments. 

As the U.S. pushes the UK and Europe towards self-reliance, the imperative for defense investment is clear. Defense innovation has moved from a fringe issue to an existential one, and the UK’s latest review was a clear sign that its importance is finally being properly acknowledged. But there is more to be done.

The evolution of warfare

Warfare is increasingly decentralized and technology-driven, marking the biggest change in conflict since the advent of flight. This decentralisation means that front lines and battlefields no longer exist in the same way, and conflict isn’t confined to physical, kinetic combat. Instead, cyber-attacks and sabotage have become standard elements of state conflict. 

Ukrainian officials report that Russian cyber-attacks have surged dramatically since the invasion, with roughly 70% more attacks in 2024 than the previous year. These are not indiscriminate attacks either; more than half targeted government systems, with a drastically increased share aimed at military command and control infrastructure. 

This threat exists beyond active warzones too. Critical national infrastructure is being targeted across Western nations by various cyber-criminal and hacktivist groups, as well as state actors. The tactics have transcended low-level website defacements and data theft too and now extend to more destructive attacks on systems such as energy grids, gas pipelines, and undersea cables. Given that an attack on servers or substations can be as devastating as an attack with shells and missiles, any effective defense strategy must now treat digital threats with the same level of severity as physical ones. 

AI and autonomy on the battlefield

Alongside this cyber warfare, there has also been a rapid advance of AI and autonomous systems on the battlefield. Drones and robotic platforms are increasingly controlled by AI, allowing them to reconnoitre, identify targets, and attack without direct human control. Both Russia and Ukraine have invested heavily in these capabilities, effectively ushering in a new era of partially autonomous fighting. This kind of ‘autonomy at the edge’, where human oversight is minimal once a system is unleashed, marks a qualitative shift in warfare. While it certainly raises difficult ethical and safety questions, militarily, it offers speed and surprise that traditional remote-controlled weapons simply cannot match.

Take Ukraine’s innovative use of drones for example. Its forces have repeatedly reached deep into Russian territory, using swarms of inexpensive drones instead of fighter jets or cruise missiles. In March, it launched its largest ever attack, sending 343 drones to the Moscow region, forcing the shutdown of all four of the Russian capital’s airports. In June, its ‘Spiderweb’ operation saw more than 100 drones deployed deep within Russian territory, striking airbases up to 4,500km away from the border.

The devastating power of these relatively inexpensive unmanned aerial vehicles (UAVs) is reshaping the tactics of warfare. The Spiderweb strikes have been described as a “low-cost precision strike operation”, demonstrating how a nation lacking heavy, long-range missiles can still inflict serious strategic losses. 

There is also a grim side to this revolution. Each of these inexpensive UAVs, and indeed any device connected to the internet, is a target for cyber warfare. This presents another opportunity to hack and disable or repurpose, instantly turning an asset into a vulnerability. 

The very strengths of autonomous weapons — that they are cheap, scalable, and effective — will also make them the tools of choice for rogue states or terrorist actors. Many existing defenses, like airport security checkpoints or traditional anti-aircraft systems, are ill-suited to this threat, forcing a rethink of protection strategies for public venues and critical infrastructure. 

A defense industry for the future

NATO recognizes that it is on the cusp of a watershed moment, and that it is in a race against time to adapt to an ever-evolving threat landscape. Military force is no longer solely defined by tank or troop numbers, but by technology, agility, and resilience. 

The UK, for example, has set up joint task forces between the military and industry to harden energy infrastructure and is investing in rapid restoration capabilities for communications networks. This blurring of what is ‘defense’ is important as the potential attack surface becomes both global and digital. We must now also consider resilience across the economy as part of our broader defense strategy. 

The age of decentralized and hybrid warfare demands a more agile and innovative Western response. Increasing military and defense budgets to include cyber and infrastructure protections is a good start. Doubling down on technological innovation and fostering closer government-industry collaboration would be an excellent next step.

Shigeru Ishiba, Japan’s Prime Minister, Steps Down

0

Japan’s Prime Minister Shigeru Ishiba has announced he is stepping down after less than a year in the role, following two major election losses.

The move comes a day before his Liberal Democratic Party (LDP) was expected to vote on whether to hold an internal leadership vote that could have forced him out.

The LDP has governed Japan for almost seven decades, but under Ishiba it lost its majority in the lower house for the first time in 15 years and then lost its majority in the upper house in July.

Japan, the world’s fourth-largest economy and a key US ally, now faces a period of political uncertainty as tensions rise with China and regional insecurity mounts.

“Now that a conclusion has been reached in the negotiations concerning the US tariff measures, I believe this is precisely the appropriate time,” Ishiba said, referring to a deal signed last week to ease tariffs imposed by US President Donald Trump on Japanese cars and other exports.

Until Sunday, he had resisted calls to resign, saying it was his responsibility to settle the dispute with Washington before stepping down.

“I have strongly believed that negotiations concerning the US tariff measures, which could be described as a national crisis, must be brought to a conclusion under our administration’s responsibility,” he said.

The 68-year-old said he would continue his responsibilities “to the people” until a new prime minister was selected.

Ishiba, who took office in October 2024 promising to tackle rising prices, struggled to inspire confidence as the country faced economic headwinds, a cost-of-living crisis and fractious politics with the US.

Inflation, particularly the doubling of rice prices in the past year, was politically damaging.

Public support further slid after a series of controversies, including criticism of his decision to appoint only two women to his cabinet and handing out expensive gifts to party members.

EU halts investigation into Universal’s $775 million Downtown deal

0

The European Commission has temporarily paused its investigation into Universal Music Group‘s proposed acquisition of Downtown Music Holdings.

Reuters reported on Thursday (September 4) that the EC has paused its inquiry ‘while awaiting requested information’.

UMG’s Virgin Music Group revealed in December that it had agreed to buy Downtown Music Holdings LLC in a $775 million deal.

Europe’s competition regulator announced in April that it was preparing to investigate the proposed acquisition and confirmed in July that it had opened an in-depth (Phase 2) inquiry, following an initial Phase 1 investigation.

The EC said in a press release in July that it had “preliminary concerns that the transaction may allow UMG to reduce competition in the wholesale market for the distribution of recorded music in the European Economic Area (EEA) by acquiring commercially sensitive data of its rival record labels”.

Reuters reports that the European Commission ‘stopped the clock’ in the investigation on Tuesday (September 2).

“The ‘clock’ in merger investigations can be suspended if the parties fail to provide, in a timely fashion, an important piece of information that the Commission has requested from them (for its competition assessment) within a prescribed deadline,” Reuters quotes a Commission spokesperson as saying.

The European Commission originally had until November 26 to make a final decision following its Phase II investigation into the deal, but according to the EC website, this date was recently extended by 10 working days, (until December 10).



Reuters reports that a new deadline will be set by the EC ‘once the investigation resumes’.

“We are confident that the Commission will recognize the benefits of the transaction for artists, labels, and independent music in Europe, and clear the transaction.”

Universal Music Group

“We look forward to continuing to work constructively with the Commission to convey the benefits this transaction will bring to the independent music community in Europe,” a UMG spokesperson told MBW on Thursday.

” This deal is about offering independent music makers access to world-class tools and support to help them succeed. We are confident that the Commission will recognize the benefits of the transaction for artists, labels, and independent music in Europe, and clear the transaction.”

According to the EC website, the deadline has been suspended under Article 11(3) of the EU Merger Regulation.

Article 11 of the EU Merger Regulation (Council Regulation 139/2004) deals with requests for information that the European Commission can make during merger investigations. The provision operates on two levels: simple requests under Article 11(2) and formal legal decisions under Article 11(3).

As the EC explains here, the formal decision must “state the legal basis and purpose of the request”, specify exactly what information is required, and establish a firm deadline for compliance.

It appears that Article 11 is not limited to requests of information from the parties involved in the deal.

According to Article 11(1), the EC has the power, “by simple request or by decision, [to] require the persons referred to in Article 3(1)(b), as well as undertakings and associations of undertakings, to provide all necessary information.”

In other words the legal framework empowers the EC to request information from any undertakings (other companies), associations of undertakings (industry groups and trade bodies), as well as the parties directly involved in the proposed deal.

When companies fail to respond adequately to an Article 11(3) decision, the Commission can “stop the clock” on its investigation timeline – precisely what has happened in the UMG-Downtown case.

This suspension mechanism serves dual purposes: it prevents companies from running down investigation deadlines through non-cooperation, while giving them additional time to compile complex information requests.


Once the investigation resumes, a new deadline is set, and the EC reaches its conclusion, it can clear the merger (with or without conditions) or prohibit it entirely if competition concerns cannot be adequately addressed.

According to the EC, “the opening of an in-depth inquiry does not prejudge the outcome of the investigation”.

As previously reported by MBW, the UMG-Downtown deal did not meet the EU’s standard turnover thresholds that would typically require notification to Brussels, but it did trigger notification requirements in both the Netherlands and Austria based on their respective national thresholds.

The EC decided to look into the deal because the Netherlands triggered a legal mechanism in EU competition law called Article 22. Austria subsequently joined the referral.


As we await news about new timelines in the investigation, the global music industry debate about the deal’s implications continues.

Yesterday (September 3), Downtown Music CEO Pieter van Rijn issued an open letter commenting on UMG’s proposed acquisition of his company.

Van Rijn addressed what he calls “whispering campaigns of misinformation that we have seen pervade the public debate” about the deal.

In July, Virgin Music Group’s bosses slammed what they called “juvenile and offensive falsehoods” spread by opponents of VMG’s planned Downtown acquisition.

Also in July, over 200 people signed a letter objecting to UMG’s proposed takeover of Downtown, including 20 employees from Beggars Group and Secretly Group companies.

On July 2, the European Composer & Songwriter Alliance (ECSA) issued an open letter to the European Commission on Wednesday (July 2) urging it to block the planned acquisition.
