ROBOTIC FISH CAPTURES MICROPLASTICS IN THE SEA

 ROBOTIC FISH CAPTURES MICROPLASTICS IN THE SEA

When I first heard about a robotic fish designed to capture microplastics in the ocean, I thought it was one of those high-tech science fiction ideas that cost billions and require rocket scientists to build. But as it turns out, the idea is remarkably simple—and refreshingly doable.

Meet “Gillbert,” a small 3D-printed robotic fish created by Eleanor Mackintosh, a student at the University of Surrey in the UK. Gillbert swims through the water like a real fish, filtering out microplastics—those tiny plastic fragments less than five millimeters in size that have now invaded almost every corner of our planet, from Arctic snow to human bloodstreams.

Unlike large, complex cleanup machines designed for floating bottles and bags, Gillbert focuses on the invisible enemy. It uses a gill-like filtration system that “inhales” water, traps microplastic particles, and releases the cleaned water as it swims. Think of it as a gentle underwater vacuum cleaner that never complains and never pollutes.

Now here’s what fascinates me most: this breakthrough didn’t come from a billion-dollar research lab, but from a university student with a 3D printer, curiosity, and purpose. I once interviewed a local drone designer who sheepishly admitted that his invention was built using nothing more than Arduino and Raspberry Pi components—tools so simple that even grade-school students now use them. This shows that true innovation doesn’t always need massive funding. It just needs imagination—and a bit of initiative.

So here’s a thought: if one student can build a robotic fish in her garage, why can’t our own universities do the same? Why not fund Technology Business Incubators (TBIs) in both public and private universities to develop Filipino versions of Gillbert? After all, the Philippines is an archipelagic nation—we have more coastlines than most countries on earth, and sadly, we’re also one of the biggest contributors to ocean plastic pollution.

If we are morally responsible for polluting our seas, shouldn’t we also take moral responsibility for cleaning them up?

Imagine building thousands of these robotic fish and releasing them into our coastal waters like schools of small, tireless janitors. Each one could patrol our rivers, estuaries, and bays—silently collecting plastic particles that harm marine life. We could even give them local names—Isdang Bayani, perhaps?

Of course, this raises practical questions: Which agency should take the lead? The DOST could spearhead the research and development. The DENR could integrate it into marine cleanup programs. The Philippine Coast Guard could deploy them, and the Philippine Navy could manage offshore operations. We could even link this effort with barangay-level environmental patrols and youth STEM programs to get students involved in designing, maintaining, and deploying the bots.

This idea fits perfectly into what I call “circular design”—where technology, community participation, and sustainability all loop together. Instead of treating waste as waste, we turn it into opportunity. Collected microplastics could be processed into eco-bricks, recycled tiles, or even artisan products.

Interestingly, China has also developed its own version of a robotic fish—just 13 millimeters long—made from a flexible, pearl-like material that’s powered by light, not batteries. It swims autonomously, collects microplastics magnetically, and could one day work in swarms to clean deeper waters. Between the British and Chinese prototypes, the world now has at least two working models proving that this concept is viable.

But I’m not suggesting we just copy these designs. Filipinos are natural tinkerers—we can improve them, tropicalize them, and make them cheaper. With our pool of local engineers, robotics students, and makerspaces, we could even integrate sensors that track pollution data in real time. Imagine a national “Digital Ocean Map” showing which areas have the highest concentrations of microplastics, updated live by fleets of robotic fish built by our own people.

Microplastics are now in our fish, salt, and drinking water. According to the World Health Organization, the long-term health effects are still unknown, but studies already link them to inflammation, hormonal disruption, and potential carcinogens. In short, they’re not just an environmental issue—they’re a public health issue.

That’s why this invention is so important: it’s not just a machine—it’s a symbol of accountability. It reminds us that small, simple innovations can tackle massive, complex problems.

So here’s my challenge to our policymakers and universities: instead of spending millions on imported solutions, let’s build our own robotic fish. Fund local inventors, engage students, and deploy technology that makes both scientific and moral sense.

We often talk about cleaning our beaches. Maybe it’s time we start cleaning our waters—from the inside out. And maybe, just maybe, it will be robotic fish—not politicians—that save our seas.

RARE EARTH DEPOSITS FOUND IN MINDANAO?

 RARE EARTH DEPOSITS FOUND IN MINDANAO?

If the recent reports about rare earth deposits in Mindanao turn out to be true, the Philippines could be sitting on a game-changing discovery—one that could transform our country from a resource-dependent economy into a global technology and energy powerhouse. But as I often say, when a story sounds too good to be true, it deserves to be checked twice, maybe even thrice.

A geologist friend of mine was cautious enough not to call the circulating news “fake,” but he did say it came from an unverified source. That alone should make us pause. And yet, as someone from Mindanao myself, I can’t help but feel a spark of excitement. Could this be the beginning of a new chapter in our nation’s development—or just another overhyped rumor?

What puzzles me most is the silence of the major media outlets. If the discovery is legitimate, why aren’t they reporting it? If it’s false, why hasn’t anyone officially debunked it? In either case, this matter deserves official attention. The DENR, along with the Mines and Geosciences Bureau (MGB) and DOST, should immediately conduct verification studies. Let’s literally “get to the bottom” of this—both scientifically and geographically.

What Are Rare Earth Elements Anyway?

Rare earth elements, or REEs, are the unsung heroes of modern technology. They make our smartphones smarter, our electric vehicles faster, and our wind turbines stronger. They’re also essential in satellites, laser systems, and fighter jets. In short, rare earths are the building blocks of the 21st-century economy.

Currently, China controls more than 80% of the world’s rare earth supply and nearly 90% of the processing. This near-monopoly gives Beijing immense leverage over global industries. If Mindanao truly holds one of the largest and most accessible rare earth deposits in the world, as some reports claim, it could disrupt that monopoly and put the Philippines in the middle of a new geopolitical race.

The Opportunity and the Risk

There’s no denying the potential. Properly managed, this discovery could generate billions in export revenue, create jobs, and fund infrastructure. It could also give the Philippines strategic leverage in international relations—imagine the world’s tech powers courting our cooperation.

But there’s also a darker side—the so-called resource curse. Countries rich in natural resources often end up poorer, not richer, due to corruption, environmental destruction, and conflict. We’ve seen this story unfold in places like the Congo, Venezuela, and even our own history with mining in Surigao and Palawan.

Mindanao, in particular, has had its share of insurgency and land disputes. Without strong governance, the rush for rare earths could reignite tensions, displace indigenous communities, and damage fragile ecosystems. Let’s not forget—rare earth mining is notoriously toxic. It produces radioactive waste, contaminates water, and destroys forests if not strictly controlled.

What Should Be Done Now?

First, verify. The government must immediately confirm whether these deposits truly exist and how large they are. This means mobilizing the MGB and DOST, with transparency and public reporting at every step.

Second, prepare a governance framework before any mining starts. This should include:

• Free, Prior, and Informed Consent (FPIC) for indigenous peoples;
  
  

• Benefit-sharing mechanisms so local communities directly receive royalties and social development funds;
  
  

• Green extraction technologies, minimizing toxic runoff and allowing waste recovery;
  
  

• And a National Rare Earth Strategy aligning DENR, DOE, DTI, and LGUs toward sustainable and transparent management.
  
  

Third, we must choose our partners carefully. If we’re to collaborate with foreign firms, let’s work with those that respect our sovereignty and environmental standards—not those that see us as another resource colony.

Lessons from Other Countries

Japan, the U.S., and the European Union are all looking for alternative rare earth sources to reduce dependence on China. Vietnam, for instance, recently discovered vast REE deposits and is now setting up sustainable extraction programs with Western partners. The Philippines could do the same—but only if we put governance first.

According to the Fraser Institute’s Mining Investment Index, the Philippines jumped from 72nd to 16th in global investment attractiveness this year. That’s good news—but it also means more eyes are on us. With the new Mining Fiscal Regime (RA 12253) designed to increase mining’s contribution to GDP from 0.5% to 2%, the timing couldn’t be more critical. We must ensure that new investments translate into national benefit, not just corporate profit.

A Final Word

If Mindanao truly holds vast deposits of rare earths, this could be our equivalent of a “Middle Eastern oil moment.” But unlike oil, this resource powers the clean technologies of the future—electric cars, wind turbines, and semiconductors. In other words, this is not just a mining issue; it’s a national development strategy waiting to be written.

But let’s not rush. Let’s be scientific, strategic, and sovereign in our approach. The greatest tragedy would be to discover something so valuable, only to lose control of it to corruption or foreign exploitation.

If the news turns out to be true, let it be the start not just of a new mining era—but of a new governance era.

As I like to say, Isang Bayan, Isang Kabuhayan—but this time, maybe it’s also Isang Minahan, Isang Kinabukasan.

WHAT IS SALINITY GRADIENT ENERGY?

 WHAT IS SALINITY GRADIENT ENERGY?

Just when I thought mankind had already discovered every possible source of renewable energy—solar, wind, geothermal, hydro, tidal—now comes another: salinity gradient energy, also known as blue energy. And unlike other renewables, this one literally comes from where the river meets the sea.

To put it simply, blue energy draws power from the natural chemical reaction that happens when freshwater from rivers mixes with saltwater from the ocean. Imagine a quiet estuary—no windmills, no turbines, no solar panels—just a steady, invisible exchange of ions through a thin membrane. That’s electricity being born from the chemistry of water itself.

In Japan, a pioneering blue energy plant is already proving that this works. Using a process called reverse electrodialysis (RED), the plant harnesses the flow of ions between saltwater and freshwater through stacks of ultra-thin membranes. Each layer functions like a miniature battery. Multiply that by thousands of layers, and you have a compact, silent power plant that runs day and night, rain or shine. No combustion, no emissions, no noise—just clean, continuous power.

Now, imagine what this could mean for a country like ours—the Philippines, an archipelago surrounded by saltwater and crisscrossed by rivers. We have thousands of points where freshwater meets saltwater. Each one could potentially become a micro power source.

The Department of Energy (DOE) should be taking the lead in exploring this technology, in collaboration with DOST for research and materials science, and DENR for environmental management. This is one of those rare opportunities where nature gives us the ingredients—all we need to do is provide the science and political will.

If necessary, Congress should pass a “Blue Energy Development Act” to create a national framework and funding mechanism for pilot projects. We’ve seen this before with solar and wind incentives—why not for something we have in abundance?

Globally, experts estimate the theoretical potential of salinity gradient energy to be between 1.4 and 2.6 terawatts (TW)—enough to supply a large share of global energy demand. It’s predictable and continuous, unlike solar or wind, and its energy density (per cubic meter of water) is roughly equivalent to the energy of water falling from a 260-meter-high dam.

So why hasn’t this become mainstream yet? Like most innovations, it faces challenges. The biggest hurdle is cost—especially the specialized ion-exchange membranes, which make up to 80% of the capital expense. These membranes are also prone to biofouling, or clogging from organic matter, which raises maintenance costs. And since the technology is only viable where rivers meet seas, site selection is limited.

But new nanomaterials and anti-fouling coatings are being developed to solve these issues. The Netherlands, Japan, and South Korea are already testing improved systems that can generate higher power density at lower cost. In time, these breakthroughs could make blue energy as competitive as solar or wind.

For the Philippines, blue energy has unique potential. Think of barangay-level micro plants at river mouths—small, modular installations that could power fishing villages or coastal schools. They could serve as disaster-resilient backup power during typhoons, when sunlight and grid connections are unavailable. Combined with aquaculture zones, they could even create dual-use systems—providing both fish and electricity.

Here’s a simple question: if Japan can generate electricity by mixing seawater and river water, why can’t we? We have more coastlines than Japan—36,000 kilometers of them! And yet, we’re still burning imported coal to keep our lights on.

It’s time to rethink how we define “renewable.” For too long, we’ve focused only on the energy we can see—sunlight, wind, waves. But blue energy reminds us that the unseen chemistry of our environment may hold the cleanest power of all.

In the long run, whatever investment we make in this field will be worth it. Every kilowatt we generate locally is a step away from dependence on imported fossil fuels. Every barangay that becomes energy self-sufficient is a community that can stand on its own during disasters.

The science is already proven. What remains is the political will and the policy support to turn this invisible energy into visible progress.

If we truly believe in “Isang Bayan, Isang Kabuhayan,” perhaps it’s time to include “Isang Enerhiya” as well—a clean, local, and constant power source that flows, quietly but powerfully, from the meeting of our rivers and our seas.

WHAT IS THE CORRELATION OF DYSFUNCTION TO CORRUPTION?

WHAT IS THE CORRELATION OF DYSFUNCTION TO CORRUPTION?

We keep seeing it in our country: broken promises, half-built roads, interminable queues at public offices, and the ever-looming suspicion that money meant for the public good ended up somewhere else. In the Philippines, there is indeed a definite correlation between dysfunction and corruption—but the real question is: why don’t we always see that link clearly? And once we do, how can we break the vicious cycle?

---

But why don’t we see it?

What makes dysfunction and corruption intertwined but hidden from plain view? I suggest three reasons: first, because dysfunction is often seen as “just how things are” rather than a symptom of something deeper; second, because corruption thrives where dysfunction has already set in; and third, because the relationship isn’t always linear, making it easier to blame one side rather than look at them both.

---

What could make us see it?

We’ll start seeing it when we shift our lens: from looking at isolated delays or scandals, to seeing the structural patterns. For example, the latest Transparency International Corruption Perceptions Index shows the Philippines scored 34 out of 100 in 2023, ranking 115th of 180 countries. That low score is a reflection of the corruption side. But what about the dysfunctional side? When public services consistently fail, when institutions overlap yet don’t coordinate, when bureaucratic delays are the norm, that dysfunction is the fertile ground for corruption.

---

Is it cause and effect? Does dysfunction cause corruption—or the other way around?

My view: it is both. There’s a cycle rather than a single-direction arrow.

Corruption → dysfunction

• When public funds are siphoned off, the resources for actually delivering services disappear.
  
  

• Appointments based on favoritism rather than merit degrade performance.
  
  

• Oversight bodies compromised by graft cannot enforce laws effectively. Thus, corruption cripples the service capacity.
  
  

Dysfunction → more corruption

• When processes are opaque, paperwork multiple layered, approvals unclear, then opportunities for bribes flourish.
  
  

• Citizens lose trust and stop demanding accountability, so impunity grows.
  
  

• Agencies working in silos with weak mandates provide cover for irregularities.
  Thus, dysfunction creates the breeding ground for corruption.
  
  

So yes: it is a cycle—and unless we intervene on both sides, the loop repeats.

---

Why are public services in the Philippines always broken?

Here’s what lies behind every delay, every excuse, every broken promise:

Root causes of dysfunction

• Fragmented, politicized bureaucracy: Agencies often have overlapping mandates and unclear authority. Reform is resisted.
  
  

• Corruption and patronage: Key positions and contracts are awarded on loyalty, not competence.
  
  

• Weak rule of law: Even when laws are decent, enforcement is inconsistent and skewed. 

• Underinvestment and misallocation: Budgets exist—but funds get diverted into ghost projects or padded contracts.
  
  

• Lack of citizen-centred design: Processes built for the agency, not the user; outcome: long queues, inefficiency.
  
  

Why promises keep failing

• Short-termism: Politicians chase big visible projects over systemic reforms.
  
  

• Poor continuity: Each administration launches new programs; many die when leadership changes.
  
  

• Tokenism: New slogans, portals, task forces—but little bite into structures.
  
  

---

How can we stop the cycle?

Here are concrete suggestions:

• Institutional re-engineering: Clarify mandates, merge overlapping agencies, create performance-based systems.
  
  

• Community-led monitoring: Empower citizens to track budgets, report abuse, help design services.
  
  

• Digital transparency with teeth: Real-time data, audit trails, citizen dashboards—not just nice websites.
  
  

• Merit-based appointments & career service reform: Depoliticise the bureaucracy, invest in training.
  
  

• Target both dysfunction and corruption simultaneously: Because fixing one without the other limits impact.
  
  

---

Do we need our own “DOGE”?

In the U.S., there is the Department of Government Efficiency (abbreviated DOGE). Created by executive order in January 2025, its goal: modernise federal technology, maximise productivity and cut waste in the U.S. federal government. 

Don’t we need something like that here in the Philippines? A strong, independent agency that focuses on both government efficiency and anti-corruption in one package? I believe yes. Because when dysfunction and corruption are two sides of the same coin, isolating one does not fix the problem.

Can we combine anti-corruption czar + pro-efficiency czar into one?

Absolutely. Instead of having one agency chasing corruption, and another chasing efficiency, we need a unified model: one agency empowered to both reduce waste, streamline processes and detect, investigate and prosecute corruption. The synergy matters. Efficiency mechanisms reduce the space for corruption; anti-corruption mechanisms improve functioning systems.

What are the best examples in the world?

• Countries with strong integrity frameworks (Nordic countries) show us that high efficiency and low corruption go hand-in-hand.
  
  

• Digital governance models (Estonia, Singapore) show how processes and transparency can reduce graft.
  
  

• Some budget-tracking/blockchain pilots (although not yet big in the Philippines) show promise: fewer manual steps = fewer opportunities for bribes.

The correlation between dysfunction and corruption in the Philippines is not just strong—it’s cyclical and self-reinforcing. Corruption degrades service delivery, which makes systems dysfunctional, which then creates new opportunities for corruption. We often fail to see this because we treat each delay or scandal in isolation. But what we need is holistic reform: one that tears down the walls of dysfunction and builds up the structures of integrity and efficiency.

If we ever want services that actually work—schools that educate, roads that last, health systems that heal—then we can no longer ignore the root causes. We need transparency not just as a slogan, but as a plumbing: the pipes through which our public money flows. We need merit not only as an ideal, but as the rule for every hiring. We need oversight not only in law, but in the lived experience of citizens.

And yes—it is time we ask: why don’t we have our own DOGE? One agency that says loud and clear: “Efficiency matters. Integrity matters. The two are inseparable.” Because without that, we’re doomed to spin forever in the same broken cycle.
