SAUDI ARABIA TESTS HYDROGEN-POWERED BUSES

 SAUDI ARABIA TESTS HYDROGEN-POWERED BUSES

Hydrogen power for transportation is not new technology—but what is new is that Saudi Arabia is now applying it in a systematic, scientific, and state-backed way. In Al-Ahsa, the kingdom has started testing hydrogen-powered buses under its Vision 2030 clean energy program. Each bus can travel up to 635 kilometers on a single hydrogen refill, carrying 45 passengers while emitting nothing but water vapor.

If that isn’t the very definition of clean transport, I don’t know what is.

Saudi Arabia’s Transport General Authority (TGA) launched the pilot in partnership with SATCO, a private concessionaire, and it’s not stopping there. NEOM—the futuristic megacity being built in the desert—is testing similar buses at elevations as high as 2,000 meters using Hyundai’s UNIVERSE fuel-cell electric coaches. Clearly, the Saudis are not dabbling—they are investing in the transport systems of the future.

This is where I begin to ask: Why can’t we do the same?

Hydrogen power is no longer “rocket science.” The technology is out there, proven, and increasingly affordable. So what is holding us back from developing our own hydrogen-powered bus system? We don’t lack engineers or scientists. What we often lack, unfortunately, is political will.

If I were to design such a program for the Philippines, I would place the Department of Transportation (DOTr) in the lead—but I would not stop there. The Department of Energy (DOE) and the Department of Science and Technology (DOST) must also be involved. DOTr can focus on policy and deployment; DOE can oversee hydrogen fuel production and regulation; and DOST can lead in technology adaptation and research.

We can start small—through pilot barangays and eco-zones.

Hydrogen Buses for Barangays and Beyond

Saudi Arabia’s model offers practical lessons for our archipelagic country. Imagine if we could build hydrogen-powered mini-buses for inter-island or provincial routes—say, between Calapan and Roxas in Mindoro, or around Palawan’s eco-tourism circuits. These long-range vehicles could travel hundreds of kilometers on one charge, powered by hydrogen generated through solar electrolysis.

At the barangay level, small-scale hydrogen hubs could power tricycles and community shuttles. A solar-powered electrolysis unit can split water into hydrogen and oxygen, storing the hydrogen in tanks for refueling. Some Japanese and European firms are already manufacturing such compact systems. Why not pilot one in, say, Taguig’s urban barangays or in a model eco-village in Nueva Ecija?

For inter-island transport, the same principle applies. Hydrogen-powered ferries could serve remote island clusters like the Batanes group, or the smaller islands of the Calamianes and Tawi-Tawi. In short, hydrogen mobility isn’t just for big cities—it could be the key to inclusive mobility in rural and island communities.

The Economics of Hydrogen

Skeptics will say hydrogen is too expensive. True, green hydrogen—produced from renewable energy—still costs more than fossil fuels. But prices are falling fast. According to the International Energy Agency (IEA), the cost of renewable hydrogen could drop by as much as 60% by 2030, thanks to scaling and innovation. Saudi Arabia is betting big on this trend, investing billions in NEOM’s hydrogen hub, which is projected to produce 600 tons of green hydrogen per day by 2026.

Why can’t we follow that path on a smaller scale? The Philippines has abundant renewable resources—sun, wind, hydro—that could power electrolysis plants. If we can produce hydrogen locally, we can also enhance our energy sovereignty.

Hydrogen and the Circular Economy

Hydrogen can even fit into our circular design goals. Instead of wasting treated water, we can use reclaimed water from sewage plants for hydrogen production. Agricultural waste can feed small biomass systems that power electrolysis. This integration would not only produce clean fuel but also reduce waste, aligning with sustainability goals under our own “Ambisyon Natin 2040.”

What We Need: Vision and Will

So again, the real question is: where will the political will come from?

Saudi Arabia’s leadership is setting a strong example. They’re not just talking about “green transition”—they’re building it, testing it, and proving it. We, too, could begin by forming a National Hydrogen Mobility Task Force, combining the expertise of DOTr, DOE, DOST, and even local universities.

We have a saying: “Kung gusto, may paraan; kung ayaw, may dahilan.” (If there’s a will, there’s a way.) Hydrogen power gives us a clear way forward. All we need now is the will.

If Saudi Arabia—a desert kingdom with fewer natural water resources—can run buses on hydrogen, what’s stopping an island nation like ours, surrounded by water and blessed with sunlight, from doing the same?

Maybe what we need is not more science—but more courage to apply it.

OPERATIONS RESEARCH HAS EVOLVED INTO DATA ANALYTICS

 OPERATIONS RESEARCH HAS EVOLVED INTO DATA ANALYTICS

It is just my own speculation—but perhaps not a wild one—that what used to be known as Operations Research (OR) has now evolved into the modern science of Data Analytics. And more than that, Artificial Intelligence (AI) has raised OR to a higher, stronger, and faster discipline.

I am not an economist, but I do know that economics is generally about managing scarce resources, while operations research is about maximizing those same resources. Economics defines scarcity; OR defies it.

If economists would ask, “How do we divide limited resources?” then OR replies, “How do we make the most out of what we have left?” In a world drowning in data and limited in time, that distinction has never been more relevant.

---

From Equations to Insights

Operations Research was born in the 1940s, during World War II, when mathematicians were tasked to optimize everything from radar deployment to convoy routes. It was, in essence, the science of efficiency. It used mathematical models—linear programming, simulation, queuing theory—to make the most of scarce resources under pressure.

Fast forward to today, and those same mathematical foundations have found new expression in data analytics. Where OR once optimized military supply chains, data analytics now optimizes everything from hospital staffing to urban traffic flow, from agriculture yield to disaster response.

It’s not that OR disappeared—it evolved. The models became smarter, the data became richer, and the goals became broader. We are no longer solving just equations; we are generating insights.

Descriptive analytics tells us what happened. Predictive analytics tells us what might happen. And prescriptive analytics—OR’s spiritual heir—tells us what we should do next.

---

When Artificial Intelligence Joins the Equation

The real leap came when AI entered the picture. Artificial Intelligence didn’t replace OR—it turbocharged it.

Machine learning can now generate parameters automatically, simulate thousands of scenarios, and refine models based on real-time feedback. In traditional OR, analysts might spend days tuning a model; now, AI does it in seconds.

For example, reinforcement learning (a branch of AI) can find the best decisions in complex environments—just like OR did—but dynamically and continuously. That’s why hybrid systems combining AI and OR are now used in logistics, energy grids, and even public policy.

Think of it this way: AI makes predictions, OR makes decisions. Together, they make smarter systems.

---

Maximizing National Resources Through OR + AI

Here’s an idea worth exploring: what if we could apply OR and AI to the General Appropriations Act (GAA)? Imagine a data-driven system that allocates government budgets based not just on political priorities but on mathematical optimization—maximizing social benefit per peso spent.

We could simulate different scenarios: how much more health coverage could be achieved if funds were reallocated? How can road repairs be scheduled to reduce traffic and costs simultaneously? OR can model that; AI can predict outcomes; data analytics can measure success.

If corruption is the sin of commission, then inefficiency is the sin of omission—and both rob the people of progress. OR and AI, used together, could make the government more transparent, accountable, and effective.

---

Scarcity vs. Maximization

Economics, as defined by Lionel Robbins, is the science of human behavior as a relationship between ends and scarce means. But OR is the science of maximization—it starts where economics ends.

Economics may analyze how scarce resources affect the economy. OR will tell you how to use those same resources optimally.

For example:

• Economics studies how burial land scarcity affects urban planning.
  
  

• OR models the optimal use of cemetery space through columbaria or digital memorial systems.
  
  

• Economics looks at incentives for aquaculture transitions.
  
  

• OR simulates feed ratios and harvest schedules to maximize yield.
  
  

In short, economics helps us understand why systems fail or succeed. OR helps us design how to fix them. And AI ensures that the system keeps learning as it goes.

---

The Human Side of Numbers

Still, we must not forget that behind every algorithm are people. The danger in today’s data-driven world is that we might focus so much on optimization that we forget about compassion.

AI and OR should never be tools for exclusion or control—they should be instruments for service. Data must serve the people, not the system. If we use analytics to predict who gets aid, let it be to reach the vulnerable faster, not to deny them. If we optimize budgets, let it be for equitable distribution, not mere efficiency.

As systems thinkers often remind us: optimization without ethics is just automation of injustice.

---

A Final Thought

If economics is about managing scarcity, and OR is about maximizing resources, then perhaps AI and data analytics are about illuminating potential. They take the invisible patterns of society and make them visible, measurable, and actionable.

Imagine a Philippines where every barangay uses AI-assisted dashboards to allocate resources, manage waste, plan transport, and even predict flood risks. That is not science fiction anymore—it’s within reach.

So yes, Operations Research has evolved into Data Analytics—but only in the hands of those who dare to use it wisely. Because ultimately, the goal is not just maximization of numbers, but maximization of human dignity.

HERE’S A NEW CEMENTING MATERIAL INSPIRED BY THE ROMAN EMPIRE’S ANCIENT CONCRETE

 HERE’S A NEW CEMENTING MATERIAL INSPIRED BY THE ROMAN EMPIRE’S ANCIENT CONCRETE

Who says that if a technology is already old, then it’s obsolete? The truth is, some “old” technologies are timeless. They endure because they were born of necessity, perfected by experience, and rooted in natural wisdom. Sometimes, it’s not about reinventing the wheel — it’s about rediscovering how the ancients made it roll so smoothly.

One of history’s most enduring technologies comes from the mighty Roman Empire — its ancient concrete. Consider this: the Pantheon in Rome, built nearly 2,000 years ago, still stands with the world’s largest unreinforced concrete dome, while many modern structures crack and crumble in less than a century. That’s not just impressive; it’s humbling.

Recently, a company in British Columbia called Progressive Planet announced it has developed a new material called Gladiator SCM (Supplementary Cementing Material), inspired by the strength and longevity of Roman concrete. They even filed for a U.S. patent for its composition. Their scientists combined PozGlass, a recycled-glass additive, with other natural materials to create a cementing blend that promises high durability and low carbon emissions — a perfect example of ancient wisdom meeting modern sustainability.

The company’s press release proudly notes that the name “Gladiator” pays tribute to Roman resilience. It’s also symbolic — a battle cry in the global fight against climate change and poor construction practices.

Now here’s my question: why can’t we in the Philippines pursue something similar?

Cement, Corruption, and Crumbling Roads

It’s no secret that many public works projects in the Philippines have been plagued by substandard materials and construction shortcuts — often victims of corruption and negligence. Every typhoon season, we see newly built roads washed out, bridges collapsing, and school buildings reduced to rubble.

In contrast, Roman roads, aqueducts, and ports — built without modern machines — have survived earthquakes and erosion for millennia. Their secret was a volcanic ingredient called pozzolana, which chemically reacted with lime and seawater to make their concrete self-healing. Today, Progressive Planet’s Gladiator SCM uses similar chemistry, but enhanced by recycled glass and scientific precision.

If we could bring such materials here, imagine how much stronger and greener our infrastructure could be. Why not require sustainable SCMs in public construction? This could reduce carbon emissions, improve longevity, and cut down on maintenance costs.

According to the International Energy Agency, cement production accounts for around 8% of global CO₂ emissions — more than aviation fuel. Using SCMs like Gladiator could cut that by up to 40%, depending on the mix. That’s a big deal for climate adaptation in a country like ours, where rising sea levels and stronger typhoons are becoming the new normal.

Rediscovering the Past to Build the Future

What fascinates me most about this development is how science keeps circling back to history. The Romans didn’t have advanced laboratories or AI-driven modeling — they simply observed nature and built with it, not against it. They mixed volcanic ash with lime and seawater, unknowingly creating a “living” material that grew stronger over time.

Modern scientists, through X-ray diffraction and electron microscopy, are now finding out why Roman concrete was so resilient. When cracks formed, the unreacted lime particles would dissolve in rainwater and recrystallize, effectively sealing the cracks — an early form of self-healing cement.

Progressive Planet’s Gladiator SCM takes that same idea — durability through chemistry — and pushes it into the sustainability age. They’ve even brought in Dr. Gerhard Albrecht, a world-renowned polymer scientist formerly with BASF, to perfect the formula. If that’s not a fusion of old and new genius, I don’t know what is.

A Call to Build Smarter, Not Just Faster

Here in the Philippines, our obsession with fast construction often comes at the expense of quality. We rush to meet project deadlines, pour concrete in the rain, skip curing times, and use the cheapest materials available. Then we spend twice as much repairing the damage later.

It’s time to rethink our approach. Instead of cutting corners, let’s cut carbon. Instead of pouring more cement, let’s pour smarter cement.

Imagine if DPWH or local governments partnered with universities and companies like Progressive Planet to pilot SCM-based materials in public works — starting with schools, barangay halls, or flood control systems. It could create jobs, attract green investment, and most importantly, save taxpayer money in the long run.

If ancient Rome could build monuments that outlast empires, surely a modern republic like ours can build roads that last more than a few rainy seasons.

In the End, the Lesson is Simple

Not all progress means abandoning the past. Sometimes, progress means looking back with humility and saying, “They got it right.”

The Romans built for eternity; we are building for election cycles. It’s time to change that. Let’s take inspiration from Gladiator SCM — and from the ancients who knew that real strength doesn’t just come from power, but from patience, precision, and purpose.

Because in the end, it’s not just about cementing structures — it’s about cementing values: honesty, sustainability, and respect for the future.

NEGLIGENCE AND OTHER SINS OF OMISSION

 NEGLIGENCE AND OTHER SINS OF OMISSION

Nothing in what I am going to write in this essay is going to mean anything if you do not believe in God, no matter what religion you belong to.

To be clear, negligence is not a sin in the secular context. At best, it could either be an administrative or a criminal offense, depending on what country and what laws there are in each country.

In the Christian context, there are sins of commission and there are sins of omission, the interpretation of which could depend on what tradition of Christianity is involved, and who interprets it. In short: doing wrong and failing to do what is right. The two are distinct, but both are serious.

Suffice it to say however, that in the context of this essay, I am referring to Christian believers or supposed believers—when we neglect to do something or omit an action that we should have done, we could be committing sins. In the Christian teaching there is a clear distinction between what is considered a sin, and what is considered a wrongdoing. Regardless of what religion one belongs to, it could generally be said that graft and corruption is definitely a wrongdoing, even if some violators would not consider it a sin. Perhaps in any religion, thievery or stealing is a wrongdoing—and so there it is, we do not have to complicate that. If you steal, you are committing either sin or wrongdoing, and that makes you corrupt. It is as simple as that, if I may say so.

That phrase — “Negligence and Other Sins of Omission”—is evocative, layered, and ripe for exploration. Let me unpack it; then I’ll share why I think it matters deeply in our faith, our civic life, and our inner reflection.

---

What the Terms Mean

Negligence typically refers to a failure to exercise appropriate care or responsibility—often with legal or moral consequences. Sins of omission, in contrast, are not about what we do, but what we fail to do—the silence, the inaction, the bystander effect. In Christian theology, a sin of omission is “to one who knows the right thing to do and does not do it, to him it is sin.” 

Put together, the phrase suggests a powerful indictment of passive harm—the damage caused not by malice, but by indifference, avoidance, or systemic neglect.

---

Why it Matters for Believers

For Christian believers, the idea of sin is not just breaking rules—it is about failing to live the kind of life God calls us to. According to one teaching: if you refuse to act when you should act, even though you know better, that is a sin of omission. 

This is not hair-splitting. It forces believers to ask: What have I not done that I could and should have done? It’s a mirror to our complacency. For example: refusing to share one’s faith, neglecting the neighbor in need, avoiding prayer when conscience prompts us. 

If all we do is avoid the obvious sins, but we never step in to help, to speak up, to live courageously—then, according to this tradition, we still fall short.

---

Some Real-World Implications

Let’s bring this into real life—faith meeting the world. Consider governance, public service, and sound leadership. It is easy to focus on the overt corruption (sins of commission): the stolen funds, the bribes, the rights abused. All wrong and in need of condemnation. But what about the sins of omission? Where no scandal breaks—but people suffer nonetheless?

Where systems fail to act. Where policies are not enforced. Where the poor are left unprotected, the environment unguarded, the weak unheard.

Believers must ask: What have we not done? What voices have we ignored? What needs went unmet? The omission may be less visible, but its damage is deep.

---

My Suggestions & Questions

• If you believe in God—and your faith calls you to act—then ask yourself: What am I leaving undone today?
  
  

• In your community: identify not just the active wrongs, but the gaps. Who is being left behind? What are we failing to build?
  
  

• For leaders (churches, groups, governments): adopt an “omission audit.” Not only: what did we do wrong? But also: what didn’t we do at all?
  
  

And I pose a question: If someone is faithful, morally upright in public, avoids obvious wrongs—but neglects the weak, overlooks the poor, never intervenes where they could—are they still ‘safe’? The Christian tradition warns us: yes, there is peril even in inaction. 

---

A Final Word

In many circles, negligence might be written off as “not my fault” or “too busy” or “someone else’s job.” But if you believe in God, then your life is bigger than your convenience. Your faith is not just in staying clean—it’s in doing good actively. Avoiding wrongdoing is not enough; active love and service is demanded.

So: beware the sin of omission. Recognize it. Resist it. And live in such a way that you are known not just for what you didn’t do badly, but for what you did bravely and lovingly.

The damage done by what we fail to do can often outstrip the harm of what we simply do wrong. Let’s, in faith, step into that gap. Let us act. Let us serve. Let us respond.

Because negligence—even without malice—is a betrayal of our calling.
