Australia bets on “ghost sharks” to reinforce its Navy

The technological race has also reached the bottom of the sea. Australia has taken a bold step by inaugurating a factory in Sydney dedicated to “Ghost Shark” underwater drones. Created by the American company Anduril Industries, these autonomous robots will be the Royal Australian Navy's new trump card for monitoring and protecting the country's vast maritime territory.

The contract, valued at 1.7 billion Australian dollars, provides for the development and manufacture of dozens of unmanned underwater vehicles over the next five years. The plan is for the ghost sharks to operate alongside submarines and warships, carrying out reconnaissance, surveillance and strategic defense missions.

The factory, with 7,400 square meters, is expected to reach large-scale production by 2026 and generate around 150 jobs. In addition to serving the Australian Navy, the drones may be exported to the United States and other allied countries, subject to approval by the local government.

The Australian investment reflects a global trend: the growing use of autonomous drones in maritime defense. The “Ghost Shark” is designed to operate stealthily, with sensors and navigation systems that allow for long unmanned missions.

For Australia, which is vying for influence in the Pacific Ocean amid tensions with China, the investment represents a strategy of deterrence and technological autonomy. Anduril, known for its work with the Pentagon, thus reinforces its presence in the Indo-Pacific military axis.

The “ghost sharks” are more than just machines: they symbolize a new era of silent warfare. With them, Australia is diving deep into the struggle for technological supremacy — now, in the depths of the ocean.

The factory opening follows the Royal Australian Navy’s award of a A$1.7BN contract to Anduril Australia to deliver a large fleet of Ghost Sharks over the next five years. Anduril announced the successful Program of Record designation after successfully completing the co-development contract and delivering three Ghost Shark XL-AUVs ahead of schedule and on-budget. This was a part of the AU$140M co-development contract to design and develop three Ghost Shark XL-AUVs in three years.

The new 7,400m² facility is purpose-built to produce Ghost Shark, and its commercial baseline the Dive-XL, at-scale and, subject to Government approval, for export to allies and partners around the world. It combines advanced robotic manufacturing, AI-driven logistics and a custom test tank for in-water verification of buoyancy, electrical systems and safety before sea trials.

The Ghost Shark manufacture program has commenced with Low-Rate Initial Production, moving to full scale production in 2026. It incorporates input from a supply chain of over 40 Australian SMEs and companies that provide a broad range of components, subcomponents and materials.

From waste to strategic resource: the transformation of plastic that could revolutionize batteries

Chinese scientists have developed an innovative method to transform plastic waste into high-performance carbon materials. The breakthrough could solve two urgent problems: reducing global pollution and creating more powerful, stable, and durable batteries. The discovery paves the way for a new energy and environmental era.

Plastic, one of the most widely used materials of the 20th century, has also become one of the biggest environmental challenges of the 21st century. Billions of tons are produced each year, and much of it ends up in landfills or the oceans. Now, a group of Chinese researchers has found a surprising solution: converting this waste into an essential resource for the future of batteries.

The study, published in the journal Sustainable Carbon Materials, was conducted by scientists from Shenyang Agricultural University and the Chinese Academy of Sciences. They demonstrated that plastics can be transformed into advanced carbon materials, such as graphene, nanotubes, and porous carbon—fundamental components for lithium batteries, supercapacitors, and hydrogen fuel cells.

These materials, which until now have been expensive and difficult to produce, are responsible for high electrical conductivity and structural stability. The novelty lies in obtaining them from common plastic waste, converting an environmental problem into a strategic resource.

The method combines cutting-edge technologies. The most promising is instantaneous Joule heating, capable of generating graphene in milliseconds with low energy consumption. The technique uses less than 0.1 kWh for each kilogram of material processed.

Other complementary processes include catalytic pyrolysis, which decomposes plastic polymers at high temperatures without oxygen, and one-step synthesis, which rearranges carbon atoms into highly conductive structures. The result is a porous carbon with a large internal surface area, capable of storing more lithium ions and increasing the capacity and charging speed of batteries.

The discovery not only increases energy efficiency but also offers a sustainable alternative to plastic waste. According to researcher Gaixiu Yang, from the Guangzhou Institute of Energy Conversion, the goal is to "close the loop": transforming plastic into an energy and environmentally useful resource.

Tests indicate that the carbon obtained can achieve storage capacities close to the theoretical limit of selenium batteries, maintaining stable performance for hundreds of cycles. In addition, the material can also be applied to CO₂ capture and the filtering of heavy metals in water.

Towards a circular carbon economy...Professor Yan Chen, from South China University of Technology, considers the advance a decisive step towards a circular carbon economy, a model in which waste is not discarded, but reintegrated into new value chains.

In the context of the global energy transition, batteries with recycled carbon can be cheaper, more durable and sustainable. Unlike traditional recycling, which degrades materials, this technique creates a superior product — technologically advanced functional carbon, indispensable for electronics and energy storage.

More than recycling: an energy revolution...For researchers, the goal is clear: to transform one of the biggest environmental problems of today into an energy solution for the future. If scaled up to an industrial level, the technology could drastically reduce the impact of plastic on the planet and extend the lifespan of batteries that power everything from smartphones to electric cars.

Bioenergy Technologies Office (BETO)...Despite millions of Americans depositing their plastic waste into recycling bins, much of that waste, including flexible films, multilayer materials, and colored plastics, cannot be recycled cost-effectively. In fact, only 9% of plastics in the U.S. are actually re-used and are typically “low-value,” meaning the high costs of recycling do not necessarily yield good returns.

Thanks to a new process from the University of Wisconsin (UW) – Madison, chemical engineers can now transform plastic waste into “high-value” chemicals, increasing the economic incentives for plastic recycling and creating novel pathways to recycle new types of plastics. In research published in Science, investigators led by Dr. George W. Huber, a professor of chemical and biological engineering at UW-Madison and Director of the Center for the Chemical Upcycling of Waste Plastics (CUWP), have developed a new plastics recycling method based on two chemical processes: pyrolysis and hydroformylation.

“Currently, there are limited options for cost-effective plastic waste recycling, and most generate a product with substantially lower value and quality than a virgin plastic,” says Dr. Gayle Bentley, U.S. Department of Energy (DOE) Bioenergy Technologies Office (BETO) Technology Manager for CUWP. “This exciting new technology paves the way for a circular plastics economy.”

Researchers estimate these processes will not only revolutionize plastics recycling, but could also reduce greenhouse gas emissions from the conventional production of these industrial chemicals by roughly 60 percent. “There are so many different products and so many routes we can pursue with this platform technology,” says Huber. “There’s a huge market for the products we’re making. I think it really could change the plastic recycling industry.”

More performance at the expense of design: Verdict on the Apple iPhone 17 Pro Max

The iPhone 17 Pro Max maintains Apple's familiar formula, but swaps titanium for aluminum, prioritizing lightness over luxury. The new body mixes glass, ceramic, and metal, with a good finish but small visible gaps. The design remains robust, with IP68 certification and pleasant ergonomics despite its weight.

The 6.9-inch Super Retina XDR OLED display maintains a high level of quality, with intense brightness, precise contrast, and a variable refresh rate up to 120 Hz. The anti-reflective coating improves readability in sunlight, and support for HDR10 and Dolby Vision ensures visual quality. The stereo sound remains balanced, but slightly less powerful.

The A19 Pro chip brings efficiency gains and thermal stability. With an improved GPU and a new vapor chamber, performance remains high during long sessions. The 12 GB of RAM ensures fluidity in multitasking and excellent responsiveness in demanding games, without noticeable drops.

iOS 26 introduces the new Liquid Glass design, with smooth transparencies and animations. The interface gained more customization options and better notification control. Apple Intelligence expands AI capabilities with live translation, context recognition, and automatic replies, making the system more dynamic and proactive in daily use.

VEREDICT: Apple's new Pro iPhones feature a striking design with a large camera bump. Aluminum has been revived as the casing material, which may not appeal to everyone, but it does have many advantages, including significantly longer battery life.

Unlike its predecessors, the camera bump on the Apple Phone 17 Pro Max and its little sister model, the iPhone 17 Pro, now extends across the entire width of the back cover. A look under the hood reveals why it has become so large.

The "camera plateau", as Apple calls the bump, not only houses the triple camera with its 48 MP sensors, but also the A19 Pro chip, the cellular modem and an antenna system. Apple uses the freed-up space to give the iPhone 17 Pro models larger batteries.

The iPhone 17 Pro Max's battery capacity increases from 4685 mAh in the iPhone 16 Pro Max to 4823 mAh, which goes hand in hand with a significant increase in runtime. In our tests, the XXL iPhone manages an excellent runtime of almost 29 hours when surfing the web, surpassing its predecessor by almost 8 hours.

The US model of the Apple iPhone 17 Pro Max provides even longer battery life because, unlike the EU models, it no longer has a physical SIM slot. This means that a slightly larger battery with a capacity of 5088 mAh fits into the housing.

While the chassis of last year's iPhone Pro models was made out of titanium alloy, Apple has returned to aluminum for the iPhone 17 Pro Max and iPhone 17 Pro. The main reasons for this are better heat conduction, but also lower manufacturing costs. Furthermore, the current Pro models feature a vapor chamber cooling system for the first time.

In combination with the aluminum chassis, the iPhone 17 Pro Max dissipates the waste heat generated during operation more effectively than its predecessor. This is evident, for example, in stress tests, where the smartphone can maintain its performance for longer and also suffers less performance degradation overall.

GTA 6 Trailer 3 could be around the corner as Rockstar updates homepage

Another fan theory has suggested that the next trailer for GTA 6 could release in early November. This time, it is believed to be before the alleged investor call, but this is all just speculation.

The hype and anticipation around the release of GTA 6 seems never ending. Fans are desperate for any kind of update from Rockstar and some have gone to point of harassing developers. The saner fans, however, are trying to figure out if Rockstar has left some clues about a new trailer in the updated homepage. The running theory is that it will be aired in early November, which is just around the corner.

This isn’t the first time a November release for Trailer 3 has been theorized. Early this month, another fan account shared on X that the next trailer will release on November 8, pointing to the time shown on Jason’s wrist watch in Trailer 2 as 11:08. This also aligned with the first trailer which was announced on November 8, 2023.

The GTA 6 Trailer 3 may be closer than users imagine. The rumor arises after the website of the studio responsible for the franchise received a new look on Wednesday (October 29th), without fanfare. The update gave great focus to the future release, scheduled for May 26, 2026, highlighting Trailer 2, in addition to the successes of GTA 5 and GTA Online. The suspicion is further supported by the hypothesis that the company has a certain predilection for the month of November, in which it has already revealed trailers for the predecessor GTA 5 and Red Dead Redemption 2 for PC previously.

A very strong reason for fans to believe in the revelation of Trailer 3 is that Take Two Interactive, Rockstar Games' parent company that publishes GTA 6, will have an earnings meeting for investors on November 6th. Many players believe that the new trailer will be released in the days leading up to the meeting to satisfy investors and also players who have to wait until May 2026 for the game.

However, there is another parallel theory, the "Clock Conspiracy," which has also gained traction. Some users found the time "11:08" on the protagonist Jason's watch and smartphone in the GTA 6 trailer and images, which in the American date format would mean "8/11," or November 8th. In the past, Rockstar Games has pulled many similar pranks, such as hiding the GTA 6 reveal date in a GTA Online t-shirt that went unnoticed. However, the fact that the date will be after the investor meeting and will fall on a Saturday is a bit strange and weakens the theory.

This time around, the TREVOR4REAL account on X has referenced the updated homepage for GTA 6 and derived some clues from the new image. This time, and this one seems more of a stretch, Jason’s wrist watch is showing 14:42, which totaled is 11, referring to November. Furthermore, there’s a statue in the background that has a shadow that looks like the number ‘4.’ With this, the user has surmised that Trailer 3 will launch on November 4. If this is accurate, we are only a few days away from the next GTA 6 trailer.  

They also back this claim citing Take-Two’s upcoming investor call, said to be on November 6. Releasing a new trailer before the call would give the team a boost and show progress towards the planned timeline, which the investor’s would appreciate.

Whether or not a new trailer for GTA 6 is released in early November, remains to be seen. Rockstar has been planning for new promotional content as suggested by the expanding team so it is possible that we get a new trailer, or some kind of update, before end of the year.

The moment fans have been waiting for seems to have finally arrived: the marketing for GTA 6 (Grand Theft Auto VI) has begun!

Update: The billboard was only discovered by the community now and appears to be real, but its display in Times Square is not recent; in any case, it reinforces that the marketing for GTA 6 has already started.

Similarly, a huge billboard for the game was spotted on the giant screens of Times Square in New York, marking the beginning of the promotional campaign for the highly anticipated Rockstar Games title.

The image was identified by GameRoll in a video published on YouTube by the Manhunt channel, where, for a few seconds, it is possible to see the GTA VI logo highlighted, accompanied by Lucia and Jason, the protagonists of the game, and showing that Trailer 2 is available.

The machine that transforms ocean waves into clean energy and could revolutionize the future

A European company has developed a compact generator that converts wave motion into electricity with twice the efficiency of traditional models. Inspired by the Japanese philosophy of Kaizen, the system promises clean, cheap, and resilient energy, even in the most extreme ocean conditions.

While the sun and wind already occupy a central space in the energy transition, the oceans remain an unexplored giant. Each wave carries enough energy to power entire cities, but transforming it into electricity has always been a challenge due to corrosion, storms, and technical complexity. Now, the Dutch company Wave Energy Company (WECO) believes it has found the answer: the Kaizen WEC, a modular converter that combines simplicity, efficiency, and resistance.

The name is no coincidence. "Kaizen" means continuous improvement in Japanese, reflecting WECO's strategy: perfecting every detail instead of reinventing the technology. Formed by engineers specialized in offshore environments, the company focused its efforts on reducing the Levelized Cost of Energy (LCOE), a metric that defines the real price of electricity during the lifespan of a generator.

Instead of pursuing a disruptive and complex technological leap, WECO focused on optimizing each subsystem of a known project. Its goal is clear: to drastically reduce the Levelized Cost of Energy (LCOE).

This term defines the real cost of electricity produced by a generator throughout its entire lifespan, including manufacturing, installation, operation, and maintenance. For wave energy to be viable, its levelized cost of energy (LCOE) must be competitive with that of offshore wind energy, and this company has been working on that for years.

The goal is clear: to make wave energy competitive with offshore wind power by the end of the decade.

Unlike other systems, which only take advantage of the vertical movement of waves, Kaizen uses the horizontal thrust of the sea. This movement is transformed into rotation by means of belts connected to a floating structure fixed to the ocean floor.

The heart of the system is the PTO (Power Take-Off), which converts mechanical energy into electricity. It eliminates gears and hydraulic fluids, major sources of failure in previous designs. The result is a lighter, quieter, and easier-to-maintain piece of equipment, capable of withstanding saltwater without the risk of polluting leaks.

Artificial intelligence to tame the ocean...The device also features an intelligent control system. Sensors and machine learning algorithms predict wave behavior seconds before it happens. Thus, they adjust the generator's resistance in real time, ensuring maximum energy efficiency.

In extreme conditions, such as waves over 15 meters, the equipment enters survival mode: instead of resisting, it follows the movement of the water, reducing stress and preventing structural damage.

After undergoing simulations in laboratories and test tanks, the Kaizen WEC was installed in Scheveningen, Netherlands. Assembly took only 32 minutes — a record in the sector. Each module generates around 5 kW, but its great advantage lies in its scalability: several devices can be connected to supply coastal communities, aquaculture platforms, or replace diesel generators on isolated islands.

In addition to electricity, the technology can directly power reverse osmosis desalination plants, providing potable water in arid regions. Its robustness and low maintenance requirements make it ideal for hard-to-reach locations without permanent teams.

WECO estimates achieving costs below €0.10 per kWh by 2030, which would put wave energy on par with floating offshore wind.

The ocean as an energy ally...The sea covers more than 70% of the planet and never stops moving. If initiatives like WECO's prosper, wave energy could become the perfect complement to solar and wind, bringing stability to grids and energy independence to entire communities.

The Kaizen WEC shows that the future may lie in learning from the sea, not resisting it.

Why are big tech companies rushing to thwart Chile's plans to regulate AI?

A government attempt to impose ethical limits on the use of artificial intelligence in Chile is meeting resistance from global tech giants, a debate that could set a precedent as countries around the world try to regulate the rapidly growing industry.

Chile attracts tech companies with its economic and political stability, robust fiber optic infrastructure, submarine data cables, and abundant green energy to operate energy-intensive data centers.

If the legislation passes, the country would position itself at the regulatory forefront of developing economies. Regulation elsewhere, with the exception of the European Union and China, is uneven.

There is a lot of money at stake for the Andean nation. Cloud giant Amazon Web Services (AWS) is investing $4 billion in three data centers that will open simultaneously in Santiago next year. Alphabet, Google's parent company, plans a second data center in the country and is installing a new 14,000 km data cable from Chile to Australia.

The AI ​​bill, which now heads to the Senate after being approved by the House in October, classifies AI systems according to risk: the greater the potential for harm to people or society, the more stringent the rules and oversight.

Systems with limited risk must meet transparency and security requirements, while those deemed unacceptable are prohibited. Violators can be fined up to 20,000 UTM (US$1.5 million).

The bill would complement Chile's cybersecurity law, which came into effect this year, and the data protection law, which will fully come into force in December 2026.

"This bill does not prohibit the technology; it establishes safeguards proportionate to the risks," said the Chilean Ministry of Science in response to written questions. "Well-crafted regulation fosters responsible innovation because it generates trust, legal certainty, and stable conditions for investment and creation."

In a speech to lawmakers in October, Science Minister Aldo Valle stated that the bill protects fundamental rights and the freedom to innovate without prior state approval. The question is not whether Chile will have AI, but under what rules, Valle said.

In contrast, technology executives argue that the proposal is too rigid, pointing to Europe's technological lag behind the United States as evidence that Chile is on the wrong track. And there is no clarity on the timelines.

"We are not against regulation," said Felipe Ramírez, country manager for AWS Chile, in an interview. "What we don't like to see are processes that take too long."

"Some companies might say, 'You know what, it's better to wait until the law is published before we decide what to do, because we don't want to end up working on an initiative and then realize it was illegal,'" he said.

Professor of Law Matías Aránguiz, director of the Law, Science and Technology Program at the Pontificia Universidad Católica de Chile in Santiago, stated that Chile is “exponentially increasing the technological regulatory burden” by leaning too heavily in one direction.

“I think we are somewhat neglecting the pro-investment approach because we are too focused on a pro-ethical regulatory approach,” he said, adding that Chile risks alienating technological capital.

Led by US-aligned libertarian Javier Milei, Argentina was recently chosen by OpenAI for a letter of intent to build a $25 billion data center complex.

In Brazil, President Luiz Inácio Lula da Silva signed a provisional measure granting tax benefits for the import of AI-related equipment. Google is eyeing a vast data center complex in the Rio de Janeiro region.

In Brazil, President Luiz Inácio Lula da Silva signed a provisional measure granting tax benefits for the import of AI-related equipment. Google is eyeing a vast data center complex in the Rio de Janeiro region.

Passion for AI...Chile has more than 40 data centers, mainly in the Santiago region. Francisco Basoalto, managing director of Equinix in Chile and Peru, said that the country ranks second in Latin America in terms of installed capacity, behind only Brazil.

He chairs a local data center trade association, representing dozens of technology companies, equipment suppliers, contractors, and service providers who have a keen interest in the pending legislation.

The installed capacity of data centers in Chile has almost tripled, reaching 240 megawatts since 2015, and could exceed 500 megawatts by 2030, according to the real estate company Colliers, which attributes the growth to the expansion of AI, the digitization of services, and the arrival of tech giants like Google.

The growth of data centers in Chile is due “primarily to the energy matrix, which is a key factor, and secondly to connectivity,” said Basoalto. The country is likely among the top five with the fastest broadband internet, in addition to the cables that connect it internationally. By 2030, data center capacity is expected to double, he stated.

Chilean President Gabriel Boric, a tech-savvy individual who inherited a digital agenda from his predecessor Sebastián Piñera, launched a national data center plan last year to attract technology investors, as AI adoption among Chilean companies skyrocketed.

According to a study conducted for AWS, approximately 171,000 companies began using AI last year, roughly one every five minutes. Today, 35% of all companies in the country use AI, up from 26% the previous year, and nearly nine out of ten report increased revenue as a result.

Chile ranked first in a regional AI readiness index last year, followed by Brazil and Uruguay. Local universities offer advanced AI courses to cultivate future talent.

In a speech in August, Boric praised efforts to develop a Latin American Large-Scale Language Model to combat the threat of “cultural hegemony” from countries where major LLMs originate. He joked that he has both ChatGPT and Chinese competitor DeepSeek installed on his cell phone.

— AI shouldn’t generate fear — Boric said, adding that AI can convey a poem, but not the passion it conveys. — We have to regulate it, of course, we have to think ethically. But it’s a tremendous opportunity. — he added.

Boric is not alone in trying to moderate AI. OpenAI CEO Sam Altman has urged US senators to regulate it.

“If this technology goes wrong, it can go very wrong,” he said in 2023.

Despite these reservations, industry experts say Chile cannot afford to drive away tech capital through restrictive regulations. By increasing development and compliance costs, the bill could even limit the ambitions of Boric's beloved LatamGPT.

According to Rodrigo Durán, who manages CENIA, Chile's national artificial intelligence center, the country's state apparatus still lacks the tools—and the political will—to lead a coordinated digital strategy. He points to the data center plan, which he describes as a "good statement of intent," but "lacking concrete measures."

Chile's Ministry of Science disagrees..."To claim that there is a lack of government interest is to ignore the effort made to position Chile as the digital hub of the Southern Cone," the ministry said in response to written questions. Even if senators approve the AI ​​bill, implementation will likely require regulations and other measures that may take time to develop. A law regulating app-based work, known as the "Uber law," was passed in 2023 but has not yet come into effect.

Permits and bureaucracy...Bureaucracy and unpredictability chronically hinder investment in Chile, and the technology sector is no exception. Last year, Google withdrew a license application for a $200 million data center project after an environmental court partially annulled it, mainly due to water concerns. The company stated that it is redesigning the project and will reapply for the license at an undisclosed date.

Durán highlights a disconnect between public perception and technological reality:

— There is a belief that the data center industry still operates as it did 20 years ago, when a data center could consume as much water as a copper mine. That's not how it works today.

Since Chile has a surplus of renewable energy, the challenge of powering the technological infrastructure is less about supply and more about transmission. A project aimed at bringing solar power from the northern desert to Santiago is taking longer to be approved than the data centers themselves.

"Companies need legal certainty, regulatory consistency, and a long-term vision that allows them to invest in and scale technological solutions without fear of disproportionate restrictions," said Sergio Correa, real estate manager at Colliers, in an email.

As Boric prepares to leave office in March, investors have largely given up hope for significant incentives before next year.

"I don't see any real interest from the current government in promoting technology," said Aránguiz. "They are more focused on regulating, on establishing safeguards, which is reasonable, but it's not the whole part of the job."

Engineers create an 'electrified' house that slashes energy bills

Western engineers have amalgamated the function and force of photovoltaics (PV) technology with a heat pump and a thermal battery to create a fully electrified—and energy efficient—new house. The end game is to eliminate the need for fossil fuels, achieving real net-zero energy consumption for homebuilders and homeowners around the world.

Western Engineering and Ivey Business School professor Joshua Pearce and Ph.D. candidate Shafquat Rana, in collaboration with mechanical and materials engineering chair Anthony Straatman, engineering professor Kamran Siddiqui and Magnus Homes' president Jaime Crncich, have designed and developed this first-of-its-kind energy-efficient home system. A two-story home in Komoka, Ont. (just west of London, Ont.), serves as a living lab for observational experimentation and data generation.

Preliminary results show this setup, unique in Canada, reduces electricity bills by 45%, and carbon emissions for the home by 55%. The thermal battery, which uses a phase-change material like salt or wax, stores energy efficiently, increasing solar PV self-consumption (using energy that is produced on site, rather than exporting it to the grid) by 60%. A phase change material is a substance that absorbs or releases large amounts of thermal energy during melting or freezing to maintain a stable temperature.

"Solar costs have now undercut grid electricity costs, making solar a viable and desired option for most Canadians," said Pearce, Western's John M. Thompson Chair in Innovation. "This project integrates solar panels, a heat pump and a thermal battery to provide thermal energy for heating and supplying domestic hot water demand to the entire home."

The researchers developed best practices to make a house four times more energy efficient than traditional methods by using a heat pump, which converts the sunlight-generated electricity captured by the solar panels atop the house into heat. This heat is stored in a thermal battery for future use. The researchers aim to show the technology is entirely scalable, safe and importantly, can be retrofitted into existing homes with minimal modifications.

"The goal is to prove the system's effectiveness over one year, with the ultimate aim of eliminating the need for fossil fuels in home heating altogether," said Rana, an electrical engineering student. "Once validated, we want to expand this system to other homes across Canada, and eventually around the world."

Rana outfitted the new house with wiring and sensors to track and predict energy usage, efficiency and cost savings—data both she and Crncich, the homebuilder who also lives in the house being studied, can monitor in real-time on their mobile devices and personal computers with a user-friendly app.

"We have a unique opportunity to both create and consume the energy in our homes and it's really interesting to see, both as an owner and a builder, how those two balance," said Crncich. "I think a lot of homeowners aren't aware of their consumption and that's really important for sustainability, knowing the role you're playing in the consumption and production of energy for your home."

For even more data, Rana is monitoring a second home built by Crncich (similar in model and located in the same Komoka subdivision) that was not outfitted with the integrated thermal battery and solar PV system, to compare the fully electrified home with a traditional Canadian house using grid electricity and natural gas supply.

'Electrifying' our homes...While heat pumps and thermal batteries are quite common in the U.S., regulatory approvals for both systems are relatively new in Canada. This exacerbates the energy problem, as it is very expensive to heat a home north of the border.

"Many homes in Canada, unfortunately, are not even up to current code, let alone equipped with state-of-the-art photovoltaic technology," said Pearce. "Secondly, most people heat their homes with either natural gas or electric space heating, which is incredibly inefficient and hurts financially, as Ontario is seeing electricity prices skyrocket again and again. Similarly, natural gas prices fluctuate, but solar provides a hedge against energy inflation."

Pearce says electrifying homes is a key pathway to long-term sustainability in Canada and around the world.

"If we can use renewable energy sources like solar power to provide electricity for our homes and then transfer that energy to a heat pump, for every one unit of electric energy, we get three units of heat, making them 300 percent efficient or more," said Pearce. "It's simply a far more efficient way to heat your home."

Rana says this novel approach to energy production and consumption goes far beyond providing comfort—and a lower electricity bill—for homeowners. It's about saving the planet. Rana showed in a recent study that Canada was not growing renewable energy fast enough to meet climate commitments.

"Climate change is real, and we need everyone on the planet to put even a small effort towards the fight," said Rana. "Decarbonization of the residential sector is low-hanging fruit, which everyone can see. The integration of this sustainable setup in Canadian homes, especially new ones, can help us greatly reduce Canada's carbon emissions to address the global impact of climate change."

The team's related research has been published in the journals Energies, Energy and Buildings and e-Prime - Advances in Electrical Engineering, Electronics and Energy.
