- [Top 5 Batteries for Home (And One You Might Not Expect)](https://undecided.tech/262-top-5-home-batteries/) - Adding solar panels to your home is a bright idea, but according to one report from 2020 only about 6% of installed residential solar systems included battery storage.1 2 That’s a bit of a power outage in the world of renewable energy. But with a home battery, you'll be able to store energy like a
- [How We’re Solving Nuclear Fusion’s Toughest Challenges](https://undecided.tech/how-were-solving-nuclear-fusions-toughest-challenges/) - “Woah …. Woah! This is massive!” -Matt “Welcome to the JET tokamak” -Fernanda Rimini Getting to see the JET tokamak fusion reactor in person was an eye-opening experience, but not in the way you might expect. What I got to see during my time at the Culham Science Center in the UK went well beyond
- [How Nuclear Fusion Can Benefit Us … TODAY!](https://undecided.tech/how-nuclear-fusion-can-benefit-us-today/) - What if I told you that I got to see first hand a really interesting nuclear fusion discovery that could impact our lives … today? Before you start dropping frantic comments, just hear me out. If you’re like me, the word “fusion” makes your mind go straight towards the long quest for net positive electricity
- [How IKEA-Style Wind Turbines Could Change Offshore Energy](https://undecided.tech/how-ikea-style-wind-turbines-could-change-offshore-energy/) - You know what an offshore wind turbine looks like. A giant pole, three blades, bolted to the seafloor. The catch is it only works in shallow water, around 80 meters or less. That rules out most of the ocean, which is where the strongest, steadiest winds actually are. A Swedish company called SeaTwirl thinks it has the fix. Turn the turbine on its side, float it, and flat-pack the whole thing like an IKEA bookshelf. No crane. No specialized machinery. It doesn't, sadly, come with a side of meatballs. Here's the thing. Vertical axis turbines like this have been losing to horizontal axis turbines for decades. The biggest one ever built lasted five years before it broke. So is SeaTwirl a real breakthrough, or a century-old dead end in a flat-pack box?
- [How the Super Soaker Inventor Built the Most Efficient Heat Engine Ever](https://undecided.tech/how-the-super-soaker-inventor-built-the-most-efficient-heat-engine-ever/) - What if all the heat your car engine, a factory, or a power plant throws away could run the grid instead? A new engine turns that waste heat into electricity, even the low-grade stuff today's best systems struggle with. It has no moving parts, and the wild part is who built it. Dr. Lonnie Johnson, the Super Soaker inventor, dreamed up this heat engine, called the JTEC. It could one day capture clean energy from industrial exhaust, and even geothermal heat. So is the JTEC really the machine that turns waste heat into power? Or will it make a smaller splash than the Super Soaker?
- [The Problem With Home Batteries (It's Not the Battery)](https://undecided.tech/the-problem-with-home-batteries-its-not-the-battery/) - How a Plug-In Home Battery Finally Works for Renters and Apartments. For most people right now, home batteries kind of suck. You spend ten to fifteen thousand dollars, wait on permits, and pay an electrician, and that is only if you own a house that can take one. A new plug-in home battery changes the math. It plugs into a standard wall outlet, needs no electrician, and the units link into a mesh home battery network that moves with you. I put three of them in my own house and ran the numbers. So can a battery like this really deliver backup power for renters and apartments? Or is this just a smaller box with the same old limits?
- [The $Billions We’re Burying in Plain Sight](https://undecided.tech/the-billions-were-burying-in-plain-sight/) - There's $67 billion in critical minerals sitting in your trash can right now. Old laptops, dead drills, that printer you keep meaning to throw out. The piles of waste outside old mines hold even more. By some estimates, between e-waste recycling and mine tailings, America already has nearly all the rare earth elements it needs, without digging a single new hole. One New Hampshire startup, Phoenix Tailings, is already turning toxic mine waste into wind turbine magnets using a furnace as hot as lava. Every few years someone promises a clean fix to the critical minerals problem, and every few years we keep buying them from China. So is remining actually the answer? Or is it just another shiny promise headed for the dustbin?
- [Why Do American Homes Suck?](https://undecided.tech/why-do-american-houses-suck/) - In the process of building my new home, I’ve heard time and time again from many of you that my home’s highly energy efficient features are considered standard in other areas of the world. From the type of window construction to the method of heating water, there’s plenty of room for improvement. But when tech
- [Why This Battery Is The Swiss Army Knife of Renewable Energy](https://undecided.tech/why-this-battery-is-the-swiss-army-knife-of-renewable-energy/) - How a Saltwater Battery Desalinates Seawater and Captures Carbon. Drop your phone in the ocean and you learn fast that seawater destroys batteries. So a seawater battery that actually runs on the stuff sounds backwards. Yet researchers in Korea have spent over a decade building one. This single system stores energy, turns seawater into drinking water, and pulls carbon dioxide from the air. One device doing the work of a battery, a desalination plant, and a carbon capture rig. So is this a real Swiss Army knife for our energy and freshwater crises? Or is a 3-in-1 promise just too good to be worth its salt?
- [What the Iran War Means for Renewable Energy](https://undecided.tech/what-the-iran-war-means-for-renewable-energy/) - The war in Iran just triggered the most severe oil supply shock in history. Start your 7-day free trial + unlock 4 extra months of Surfshark VPN — head to https://surfshark.com/undecided or use code UNDECIDED at checkout! Gas prices had their biggest one-month spike ever. The average American household is seeing costs spike. One-fifth of the world's oil flows through the Strait of Hormuz. Even if it reopened tomorrow, production wouldn't recover for years. So is this war actually speeding up the energy transition? Or is it just exposing cracks that were already there?
- [How Mars Technology Gave Us Cheap Energy Storage](https://undecided.tech/how-mars-technology-gave-us-cheap-energy-storage/) - Every year, some company claims they've cracked long-duration energy storage. And every year, we're still leaning on lithium-ion batteries that tap out after a few hours. You've heard the promises. You've seen the press releases. And you're probably as tired of the hype as I am. But in January 2026, a small California startup called
- [The Surprising Ways AI is Actually Helping](https://undecided.tech/the-surprising-ways-ai-is-actually-helping/) - You know that stretch where you hit every green light perfectly? Well, that might not be luck anymore. There's an AI system that watches every car, bike, and pedestrian approaching an intersection in real time… and lines up the lights so you cruise right through. And the numbers on how much faster people are getting home? They're kind of ridiculous. Speeding up your commute is just the beginning. There's a city in Tennessee where AI flagged so many near-crashes on one block that planners made a single change… and the result still blows my mind. When I saw how much safer AI made bike lanes in Vancouver, Canada, I thought maybe I was the one hallucinating. The catch? For any of this to work, the city has to see you. Cameras, radar, the phone in your pocket, the car in your driveway. It kinda creeps me out. So what do we actually get back? And is there a way to get all of this without cameras watching our every move?
- [How This Heat Pump Water Heater is Also a Battery](https://undecided.tech/how-this-heat-pump-water-heater-is-also-a-battery/) - How This Heat Pump Water Heater is Also a Battery. Go to https://ground.news/undecided for an innovative way to stay fully informed on tech, energy, the climate and more. Save 40% on the Ground News unlimited access Vantage plan with my link. Heat pump water heaters have been around for over a decade. If you follow this channel, you probably know they're three to five times more efficient than a standard electric tank. Maybe you've got one. I do. But here's what most people don't realize. Even if you own a heat pump water heater, it's still pretty dumb. It heats reactively. The tank drops below the setpoint, the compressor kicks on. It doesn't know your schedule. It doesn't know your electricity rates. And it definitely doesn't know when your solar panels are cranking. Two Boston startups think that's a massive missed opportunity. They're treating the water heater as a thermal battery, a cheap, insulated vessel that can store energy as heat, shift electricity use to cheaper hours, and participate in grid services. One of them, Wilmington, Massachusetts-based Cala Systems, invited me to tour their factory. Their predictive software is licensed from the National Renewable Energy Lab. According to a California Energy Commission study, intelligent scheduling on time-of-use rate plans alone can cut costs by 15 to 19 percent beyond what a standard heat pump water heater already saves. So I went inside to find out: is a smart water heater actually worth the premium? Or is "intelligent" just a buzzword bumper sticker slapped on a tank of hot water?
- [How Ocean Plastic Isn’t The Problem](https://undecided.tech/how-ocean-plastic-isnt-the-problem/) - I was a teenager on a cruise when I first saw ocean pollution up close. Late at night, I heard a noise over the railing. I looked down and saw crew dumping garbage into the ocean. A stream of trash stretching off toward the horizon. That image stuck with me. But that garbage spilling into
- [Why China’s Supercritical CO₂ Turbine Matters](https://undecided.tech/why-chinas-supercritical-co₂-turbine-matters/) - For over 200 years, we've been generating electricity essentially the same way: by boiling water. And it's worked! Today, steam turbines power the vast majority of the world's electricity. But this technology, which has powered us since the industrial revolution, might not be up to supplying us enough energy in this new revolutionary era of
- [The National Grid Is Dead. Here's What Replaces It.](https://undecided.tech/the-national-grid-is-dead-heres-what-replaces-it/) - In April 2025, most of Spain and Portugal went dark. A cascading failure knocked out the Iberian peninsula's grid in seconds. Just four years earlier, Texas came within 4 minutes and 37 seconds of its own total collapse.1 Not a temporary blackout. A full shutdown. What engineers call a "black start," a process that could
- [Why This Vertical Farm is 500x More Efficient Than Farming](https://undecided.tech/why-this-vertical-farm-is-500x-more-efficient-than-farming/) - This is Vertical Harvest. Sitting on half an acre of land, it produces as much food as an equivalent 250-acre farm. That’s a 500 times more efficient use of land than traditional farming. But if vertical farming is so great, why isn’t it more popular? And where and why does it make the most sense?
- [What I Got Wrong Building My Net Zero Home](https://undecided.tech/what-i-got-wrong-building-my-net-zero-home/) - I have some regrets. A few years ago, I set out to build my dream net zero energy home. I've been living here for a little over two years now, and so far, I’ve been more than satisfied. I have enough solar and battery storage to balance out all of my annual energy use. A

A capacitor. Vaporware. A scam. Except when you actually dig into those explanations, a lot of them start falling apart. Here's what Donut Lab is actually claiming: more energy per pound than today's best lithium cells.
- [Why Waiting for Perovskite Solar Isn’t Worth It (Solar 3.0)](https://undecided.tech/why-waiting-for-perovskite-solar-isnt-worth-it-solar-3-0/) - Perovskite solar cells could hit 35% efficiency and cost half as much as silicon, but they're still years away from your roof. Meanwhile, silicon panels just lost their 30% federal tax credit in the US, making them suddenly more expensive. So here's the $20,000 question: what’s the better path and value? Should you wait for
- [Geothermal vs Air Source Heat Pump: Which is Worth It?](https://undecided.tech/geothermal-vs-air-source-heat-pump-which-is-worth-it/) - What if the most efficient way to heat and cool your home…might not actually be the best choice for you? Geothermal heat pumps are the gold standard for efficiency. They're also the most expensive upfront investment you can make in your home's HVAC system. So, are they really worth it? Or should you go with
- [How 40-Ton Spinning Wheels Are Saving the Power Grid](https://undecided.tech/how-40-ton-spinning-wheels-are-saving-the-power-grid/) - When Spain's power grid failed on April 28th, 2025, it quickly became a very serious issue. Not only for the economic impacts, but life-or-death serious due to multiple, indirect deaths associated to the blackout. Emergency services, transportation, communication and other vital services were halted during this power outage. Not only did it blackout Spain, it

Flow batteries alone have enough variations in chemistry to make your head spin. Zinc-bromine batteries are one up-and-coming contender … and calling them up and coming sounds funny when you consider that they’ve existed for 137
- [Exploring Electricity Free Cooling with Aerogel](https://undecided.tech/exploring-electricity-free-cooling-with-aerogel-2/) - Whether it’s to regulate the temperature of food, medicine, or people, we’ll always need some form of cooling tech to survive. We tend to turn to air conditioning to solve these problems, but that has us stuck in a positive feedback loop that isn’t at all positive. Hot days are becoming hotter, and the demand
- [Why This 17-Year Old's Electric Motor Is Important](https://undecided.tech/why-this-17-year-olds-electric-motor-is-important/) - Where there’s tech, there’s magnets. The strong magnets that generate their own magnetic field, AKA permanent magnets, aren’t only on your fridge. They’re in multiple places inside your fridge, and in your cell phone, headphones, and hard disk drive, too. Permanent magnets are also a critical resource for renewables, because the generators in some wind
- [How A Brick & Rock Battery Is Changing Energy Storage](https://undecided.tech/how-a-brick-rock-battery-is-changing-energy-storage-2/) - Grid-scale lithium-ion batteries are our current go-to chemical energy storage solution, but they present their own challenges in safety, sustainability, cost, and longevity.

- [Fixing Solar Panels Fatal Flaw](https://undecided.tech/fixing-solar-panels-fatal-flaw-new/) - The solar industry has a potentially fatal flaw: its reliance on silver. As a precious metal, silver is costly and difficult to come by, yet critical to pretty much every kind of solar panel.1 Worldwide solar capacity has officially crossed into terawatt territory and silver is putting that continued growth at risk.2 There is an
- [The Problem With Gas Stoves](https://undecided.tech/the-problem-with-gas-stoves-2/) - Gas stoves have been quite the “hot button issue” lately. But a range of data from decades’ worth of research has already reached a consensus: Cooking with gas is dangerous to human health and a significant source of greenhouse gas emissions. Electrification has been ongoing, with Europe leading the way in adopting induction cooking.1 However,
- [Why Worms May Be the Future of Plastic Recycling](https://undecided.tech/why-worms-may-be-the-future-of-plastic-recycling/) - The vast majority of the world’s plastic isn’t recycled … and when it is, we spend more money to achieve less quality. It’s currently cheaper to keep producing newer plastics — at the much higher cost of human and environmental health. But nature has evolved in response. Several species of insects, bacteria, and fungi can

They’re almost defying imagination at this point. Bigger is always better in the world of wind. The reason is
- [Why Salt Water may be the Future of Batteries](https://undecided.tech/why-salt-water-may-be-the-future-of-batteries/) - There’s no shortage of potential solutions to the world’s critical need for renewable energy storage. But there is a shortage of accessible and cheap resources to use for those solutions. With the limitations of materials like lithium and vanadium in mind, it’s logical to look for alternatives that are basically limitless. How about regular, run-of-the-mill
- [Why Solar Panels Aren’t Unfair or a Scam](https://undecided.tech/why-solar-panels-arent-unfair-or-a-scam/) - There’s concerns that homes with solar panels are reducing their utility bills at the expense of their neighbors without solar panels. The phenomenon is referred to as “cost shifting”: the idea that the credits utilities pay to solar homes for the energy they produce ultimately results in higher bills for customers without panels. This has

According to Our World in Data, solar’s share of global electricity production jumped from 0.15% percent in 2010 to over 4.52% in 2022.1 This has left even the most optimistic solar adoption predictions in the dust. And everyone from skeptical naysayers to the
- [Why We Need To Rethink Wind Turbines](https://undecided.tech/why-we-need-to-rethink-wind-turbines/) - Wind turbines have a “big” problem. As in, they’re really big: bigger than you might think. One of the latest turbine designs sports a swept area of about 10 American football fields.1 This is generally desirable, especially for offshore turbines. But as you can probably imagine, this makes producing, transporting, and installing these things a
- [How Offshore Solar Could be the Future of Energy](https://undecided.tech/how-offshore-solar-could-be-the-future-of-energy/) - What’s stopping us from converting the open ocean into a massive solar power plant? To the tune of almost 6 times more energy than the world uses every year. Several companies are trying to do just that by floating solar panels out on the open ocean, but that raises so many questions. Won't they get
- [Why Hydrogen DOES Have a Future](https://undecided.tech/why-hydrogen-does-have-a-future/) - In the summer of 2023, the Rijnstate hospital of Elst, The Netherlands opened its doors.

The building collects energy from over 1,300 solar panels located
- [How We Solved The Home Wind Turbine Problem](https://undecided.tech/how-we-solved-the-home-wind-turbine-problem/) - Whenever I cover wind turbines many of you ask about what’s available for home applications. At the moment, I’ve got both good news and bad news. The bad news is that the current market for residential wind is…less than great. The good news? We have a lot of new innovations that look to improve it.
- [The Genius of Small Hydro Turbines](https://undecided.tech/the-genius-of-small-hydro-turbines/) - Hydropower is a great source of energy that doesn’t suffer the same intermittency problems as other renewables. But dams fail. A lot. About 95% of the existing hydropower systems in the States were built before 1995, and over half operate using equipment designed over 80 years ago.1 This aging infrastructure can be not only unreliable,

It’s kind of hard not to with the latest ChatGPT announcement. The technologies we’re witnessing are powerful, impressive, and developing fast. Everything you’re been seeing on screen, for example, is footage from OpenAI’s new video-generating model, Sora. But let’s peel
- [Why This Window Heat Pump Is Genius](https://undecided.tech/why-this-window-heat-pump-is-genius/) - I know, I know. I talk a lot about heat pumps, but there’s a good reason for it. It’s a fantastic technology that uses a little physics exploit to get more heat energy out than energy you put in. The problem is that most of the time, the devices I’m talking about are for homeowners
- [5 BEST Alternatives to Finally Replace Plastic](https://undecided.tech/5-best-alternatives-to-finally-replace-plastic/) - Plastic is firmly established in our daily lives, but it’s only existed for about a century or so. As we consider the long-term harms of rapidly accruing pollution, it begs the question…would it be so bad to finally break up with plastics? And is it even possible at this point? It’s not like we don’t
- [Can Solar Rooftops Power the World?](https://undecided.tech/can-solar-rooftops-power-the-world/) - Growing the world’s renewable energy capacity has always been a delicate balancing act, and one of the many plates we have to spin during that act is land use. Utility-scale solar and wind parks are rapidly expanding in size and prevalence all over the world, including right near my own backyard.1 But it’s not just
- [How Compressed Air Batteries are FINALLY Here](https://undecided.tech/how-compressed-air-batteries-are-finally-here/) - We can’t control the weather (yet). But we can control how we store weather-dependent renewable energy. So how do we snatch up our lightning in a bottle? Lithium-ion batteries can only go so far…and our historical large-scale go-to, pumped storage hydropower, only works in certain locations. What if we went in a different direction: down?
- [The World’s Largest Wind Farm has a Tiny Problem](https://undecided.tech/the-worlds-largest-wind-farm-has-a-tiny-problem/) - It’s already difficult to conceptualize the scale of wind turbines themselves. It can be even harder to wrap your head around how much energy they can supply. Just one gigawatt is enough energy to power between 750,000 to a million US homes.1 Here in the United States, our largest wind farm is the Alta Wind
- [How Solid State Cooling Could Change Everything](https://undecided.tech/how-solid-state-cooling-could-change-everything/) - I talk about heat pumps a lot. They really are the most energy efficient way to heat and cool things, but they’re not the only way. There’s another form of cooling that’s been getting a lot of attention in recent years that might just lie in these bendy wires. It might seem a little abstract
- [How This TRULY Omni-Directional Wind Turbine is Genius](https://undecided.tech/how-this-truly-omni-directional-wind-turbine-is-genius/) - Small wind turbines, or SWTs, have struggled to get off the ground. Not only is siting more difficult for SWTs, but their low efficiencies rarely justify their high costs. They also have to contend with the same kinds of considerations that your typical turbine does, like noise, vibration, environmental impacts, and aesthetics. In closer proximity
- [The Insane Logistics Behind Building Wind Turbines](https://undecided.tech/how-wind-turbines-are-actually-built/) - “My God. The sheer scale of this, this is kind of blowing my mind.” -Matt Hearing about how massive wind turbines are built is one thing, but seeing it is another.

- [Why Ice Might Be the Future of Heating](https://undecided.tech/why-ice-might-be-the-future-of-heating/) - Heat from ice? It sounds like a joke—or maybe a paradox. But what if the future of warm, cozy homes lies in freezing water? As outlandish as it seems, an English research team is working on a heat pump that runs off actual ice … well, more like slushies. It’s a serious effort to tackle
- [How Magnetic Cooling Is Breaking All the Rules](https://undecided.tech/how-magnetic-cooling-is-breaking-all-the-rules/) - What if I told you your fridge — that humming box in the kitchen — could be cooled without gas, without chemicals … just magnets? It sounds futuristic, but researchers are already making it happen. It not only promises higher efficiency, but solves a critical problem with the status quo…yes, a critical problem that plagues
- [How Living Computers Could Change Everything](https://undecided.tech/how-living-computers-could-change-everything/) - It’s no secret that tech companies are racing to build “artificial general intelligence,” or AI that can match a human brain without needing a lifeline. But here’s the kicker: our brains already have the home field advantage. They do the same heavy lifting with just a fraction of the resources. Whether it’s energy, water, land,
- [How Self-Healing Solar Panels Could Change Everything](https://undecided.tech/how-self-healing-solar-panels-could-change-everything/) - Solar panels are built to last around 30 years, weathering all kinds of abuse during that time.1 That’s a solid run for any piece of tech, but what if we could push that even further? What if solar panels could last… forever? That’s the promise behind a new kind of perovskite PV cell that can
- [Why Aluminum Batteries Could Beat Lithium](https://undecided.tech/why-aluminum-batteries-could-beat-lithium/) - Your lights just flickered. Not for long. Just a split second. You probably didn't think much about it, but somewhere a battery may have just saved your city from a blackout. I’m not talking about keeping your phone charged or your EV running. These kinds of batteries are for preventing the entire electrical grid from
- [Why Everyone Gets Heat Pumps Wrong](https://undecided.tech/why-everyone-gets-heat-pumps-wrong/) - If you believe half of what you hear about heat pumps, you'd think they're a $20,000 scam that stops working the second it gets cold outside. But here's what the skeptics don't mention: modern heat pumps work in temperatures down to -26°C (that's -15°F), and those "reliability" complaints? They usually trace back to installation problems,
- [Are Sodium Batteries Already Dead?](https://undecided.tech/are-sodium-batteries-already-dead/) - NOTE: An earlier version of this story incorrectly associated the failure of Northvolt to their sodium ion battery production issues, but their challenges weren't chemistry specific. That section has been removed. I’ve got sodium batteries right here in my hands, but three sodium battery companies went bankrupt in the last year. Another shut down voluntarily
- [The Solar Underdog That Could Rival Perovskite](https://undecided.tech/the-solar-underdog-that-could-rival-perovskite/) - Perovskite solar cells are smashing efficiency records and starting to hit the market, but what if the real future of solar is a material you’ve probably never heard of? It’s called kesterite, and new research suggests it could match perovskites’ efficiency without any toxic lead in the stack. That could mean even cheaper, cleaner, and
- [BEST Things I Saw in Vegas at CES 2026](https://undecided.tech/best-things-i-saw-in-vegas-at-ces-2026/) - BEST Things I Saw in Vegas at CES 2026 CES can be a mixed bag. But between the robot invasions…and AI takeovers…I encountered tech that really stopped me in my tracks. First, a solid-state battery claim so bold that even battery skeptics are doing a double take. We're talking performance numbers that sound impossible: 400
- [How Graphene is Changing the World … Right Now](https://undecided.tech/how-graphene-is-changing-the-world-right-now/) - What if your phone battery charged in seconds instead of hours? What if buildings could cut their carbon emissions in half? What if medical sensors could detect diseases years earlier than they do today? Graphene was supposed to deliver all of this and more. Since 2004, researchers called it a wonder material. It would revolutionize
- [How Solar Changed in 2025 (And What's Next)](https://undecided.tech/how-solar-changed-in-2025-and-whats-next/) - I called 2024 the year of perovskites. We got our first commercial shipments and some record-breaking efficiencies. But 2025? This was the year perovskites went from "interesting lab tech" to "you can actually buy these." Oxford PV shipped the first commercial batch to a US solar farm.12 California startups landed major infrastructure deals.3 And Chinese
- [How Fusion Tech Just Changed Geothermal Energy Forever](https://undecided.tech/how-fusion-tech-just-changed-geothermal-energy-forever/) - Two and a half years ago, I told you about a company using "death rays" to drill deeper into the Earth than anyone has before.
