Clean Technology Meets Data Science: News and Articles

For centuries, our planet has spun on a predictable axis, a cosmic top-like motion that has governed our seasons and dictated the flow of life. But a surprising and significant new study has revealed that a seemingly routine human activity—pumping vast quantities of groundwater—is actually altering Earth's tilt, nudging its rotational pole by a measurable amount. This isn't just an abstract scientific curiosity; it's a testament to the sheer scale of human impact on the planet's systems, with long-term implications for our climate and environment. The research, published in the peer-reviewed journal Geophysical Research Letters , suggests that between 1993 and 2010, the human race extracted an astounding 2,150 gigatons of groundwater. To put that into perspective, that's enough water to raise global sea levels by over 6 millimeters, a significant contribution that has now been directly linked to the planet's wobbling. The study's lead author, Ki-Weon Seo of...

You’ve probably heard about the massive energy consumption of artificial intelligence, but there’s a hidden, and arguably more pressing, environmental cost that often goes unmentioned: water. As powerful AI models like ChatGPT become integrated into our daily lives, a new study reveals the staggering amount of water they consume, raising critical questions about the sustainability of the AI revolution. The Thirsty AI: Why Your Digital Assistant Needs a Drink When you type a query into a chatbot, you're not just communicating with lines of code. You're activating a vast network of servers housed in massive data centers. These servers are running sophisticated machine learning models, and all that computational power generates an immense amount of heat. To prevent the hardware from melting down, these data centers rely on sophisticated cooling systems—and that's where the water comes in. Data centers use massive cooling towers that function like giant swamp coolers. They pull...

The crises of climate change and water scarcity can feel impossibly vast and disconnected. One involves the invisible blanket of greenhouse gases suffocating our planet, while the other is a daily, tangible struggle for billions of people to find clean drinking water. Yet, these two problems are deeply intertwined, and the solutions, it turns out, are increasingly linked through a powerful combination of corporate commitment and technological innovation. Today, we're seeing a new wave of environmental action that goes beyond simple pledges and public relations. Tech giants like Microsoft and Apple, alongside a growing ecosystem of agile startups, are deploying significant capital and cutting-edge technology to address these dual challenges head-on. The Carbon Removal Revolution: Scaling Up a Gigaton Industry To meet global climate targets, simply reducing emissions isn't enough. We also need to remove the carbon dioxide that’s already in the atmosphere. This is where the burgeo...

You’ve heard about rising sea levels, but what if the land itself is also part of the problem? A groundbreaking new study reveals that the U.S. Atlantic coast is facing a "hidden vulnerability" to climate change, one that could put millions of people at greater risk of flooding and erosion. For years, we’ve focused on the steady increase in global sea levels as the primary threat to our coastlines. However, a   study by researchers at Virginia Tech , published in the journal  Nature Communications , shows that this is only half the story. The land along the Atlantic coast is sinking , a phenomenon known as land subsidence , and it's happening at an alarming rate. Using sophisticated satellite data, researchers were able to create high-resolution maps of the entire Atlantic coast. They found that in many coastal areas, the land is subsiding at more than 3 millimeters a year. This downward motion, when combined with the effects of sea-level rise, means that the relative sea...

 We'll be at the California Water Data Summit in a week! Join us to learn about AI in water - especially on how we build models with low-code or no-code.

The SWAN Americas Alliance report , "How Utilities Organize for Digital Innovation,"  was published a short while ago and contains some fascinating information on the state of digital innovation in the water sector. We provide a short summary here, but the full report is well worth a read. The report reveals that while a growing market of smart water technologies exists, the key to successful adoption lies in organizational and human factors . Based on a survey of 38 utility workers from 34 diverse utilities across 10 countries, the report identifies the main drivers and inhibitors of digital innovation. The primary inhibitors are a lack of time and bandwidth, organizational bureaucracy, and an unclear business case or return on investment (ROI) . The report highlights that a strong commitment to innovation builds momentum and helps attract talent. It also emphasizes that innovation shouldn't be the sole responsibility of one department, like IT, but rather a collaborativ...

The start of 2023 presented a unique and challenging environment for startups, with macroeconomic shifts influencing everything from investment strategies to company operations. These trends continued in 2024 - so taking a look back at what happened in 2023, we can paint a more comprehensive picture of the funding landscape and the opportunities that emerged amidst the challenges. The Macroeconomic Reality: A Shift in the Venture Market The "frothy" valuations of the previous years were gone, and the overall VC market was contracting as described by Cervin  in their report for 2023. This was a "déjà vu all over again" moment, with echoes of the 2008 financial crisis. The report noted a significant decline in pre-seed and seed deal value, as well as a drop in the number of active venture firms. In this environment,  "disciplined entrepreneurship," looks even more important and the advice for startups is to focus on building sustainable, scalable businesses....

The global imperative for robust environmental monitoring has never been clearer. From tracking pollution to safeguarding endangered species, the demand for efficient, real-time data collection in diverse and often inaccessible environments is paramount. Fortunately, the field of robotics is delivering innovative solutions, pushing the boundaries of what's possible in environmental sensing. Recent breakthroughs in both origami-inspired robots and bio-inspired micro-fliers are setting the stage for a new era of environmental stewardship. OrigaMechs: Sensing in Extreme Environments Traditional robots often struggle in challenging environments due to the limitations of their rigid, semiconductor-based components. These conventional chips add weight and hinder the ability of robots to be compact or adaptable. However, a multidisciplinary team at the UCLA Samueli School of Engineering is changing this paradigm with their "OrigaMechs." Inspired by the ancient art of paper foldi...

When you think of climate tech, it’s easy to picture sleek solar panels, flashy carbon-capture systems, or futuristic gadgets that sound like they belong in a sci-fi film. But some of the most impactful technologies tackling our changing climate don’t look the part. They quietly drift through oceans, perch in trees, or hover above disaster zones—often unnoticed, yet working tirelessly. Let’s talk about the robots and sensors that are turning data into action, from ocean currents to wildfire hotspots. Watching the Ocean’s Pulse (One Glider at a Time) Deep beneath the surface of the North Atlantic, robotic gliders are monitoring the state of our oceans. These uncrewed submarines are part of an ambitious mission to track changes in the Atlantic Meridional Overturning Circulation (AMOC)—a system of ocean currents that helps regulate our climate. Why do we care about AMOC? Because if the AMOC weakens significantly (which some research suggests it might), we’re looking at major disruptions: ...

If you've ever played with ChatGPT through a free account, you’ve probably been trying to see what answers you can get to common questions. Or maybe you’ve been trying to see if it can work as a virtual assistant if you’re planning travel. Or maybe you’re a software developer who’s been using Copilot and other tools that use LLMs to help you answer questions about your code when you’re stuck. We’ve been hearing a lot about ChatGPT and large-language models (LLMs) and their impacts on the jobs that are going to be available and the skills that people will need to acquire. These models together form the field of GenAI or Generative AI - often called that because they appear to generate or synthesize knowledge. Compared to regular search engines, it often seems that ChatGPT and its equivalents are producing results that are closer to human conversation. However, these models are still only a type of machine learning method; the difference is that they have been trained on extremely la...

If there is something that has become much clearer in recent years with climate change, it’s that the magnitude and frequency of natural disasters has increased dramatically in the last 5 years. The Office of Management and Budget in the US Government conducted a preliminary analysis this year and concluded that six major types of natural disasters (coastal disasters, flooding, crop failures, climate-related health disasters, wildfires and building failures)   “were likely to result in annual expenditures of approximately $134 billion and could result in as much as $2 trillion in lost revenue by the end of the century”.   As a result, there’s been a lot of interest in technologies that can help responses in the aftermath of disasters as well as those that can help detect these disasters early and hence mitigate the damage from them.   Recently, scientists from OakRidge National Laboratory helped develop a prototype system to detect damaged utility poles from hurricanes a...

Imagine H2O , one of the largest water incubators working across several countries, recently held their startup showcase day. Imagine H2O has been around for several years now and they have funded and helped promising startups in over 20 countries to date. They have several startups in their portfolio that have focused on using combined sensors or robots, machine learning and physical systems to solve problems around the world. In fact, this seems to be the focus of much of the innovation happening in the water tech sector recently! Let’s take a look at some water tech startups from around the world. AInWater : The startup focuses on using machine learning and traditional optimization algorithms to monitor waste water treatment plants and help improve the efficiency of their operations. They’ve been featured in Forbes and have been working with a number of water utilities in South and Central America. CivilGrid: A fascinating company that builds a digital twin of utility lines, enviro...

Digital twins for water, electricity and smart cities have become more than just a buzzword in the past couple of years. As we’ve discussed before, a “digital twin” of any system is when data from the system, whether through sensors, satellite imagery, drones, robots or SCADA systems, are integrated to form a digital representation of what the system looks like over time. While there have always been researchers in academia and the scientific community working on aspects of these systems, we have seen an explosion of interest across all sectors in the past couple of years. Some of that interest is due to Covid, of course. When the shutdowns happened across the world, a key question that was asked of all physical facilities, especially critical infrastructure like water treatment plants, wastewater plants and power plants, was to develop methods that would allow for remote monitoring of these systems. The answer to that question was a combination of sensor data, machine learning both f...

If you are working in the high-tech sector or are at a startup, the first half of 2023 was definitely a roller coaster. We saw venture funding dry up for many sectors; saw the collapse of the Silicon Valley Bank - the bank where many startups and venture capital funds kept their money; and observed layoffs happen in the technology giants - Google, Facebook, Apple and others. In fact, one of the VC firms, Cervin, did an analysis showing that venture funding has been at an all-time low this year, with only 19 mega deals being signed in Q1 2023 compared to 98 the previous year; funding fell by 53% for angel and seed funding and by 30% for Series A rounds. In fact, except for companies focusing on generative AI and AI adjacent technology in the high-tech sector, it has been an exceptionally difficult year financially. How did the clean-tech sector fare? Unsurprisingly, while there were some impacts on startups and their ability to raise additional funds from venture capital firms, the se...

Here's to our beautiful blue dot - with all the mountains, oceans, forests, grasslands, animal and plant life that inhabit it. If there's one thing that we as a species can do, it's doing our best to protect our world - for after all, there is no Planet B.  

How many different materials go into making your smartphone? According to the American Chemical Society, at least 64 different types of chemicals constitute your smartphone . Many of these materials, particularly the heavy earth metals, are extracted from the Earth through mining operations. Mining has been a part of human society for several thousand years now - from the shallow mines of earlier centuries to the more extractive ones created in the last hundred years. The challenge of mining and other extractive industries is that they are essential to many of our needs today - coal for energy, silicon for solar panels and heavy earths for electronics being among the well known ones. At the same time, they cause significant damage to local environments through the disturbance to the land caused by establishing the mine itself, to environmental impacts on water, land and ecosystems from mining operations.   So far, it’s been difficult to map the spatial extent and environmental impa...
