How I kept cool with NYC's free battery program for window AC units

1 Comment

My family has spent four summers participating in demand response programs whereby utility companies pay customers to reduce energy use on the hottest summer days. Most summers have involved carefully precooling our New York City apartment before switching off the air conditioners and sweating it out during the designated demand response periods.

But this year, we kept our window air conditioners running throughout a heat dome event that drove daytime temperatures into the triple digits and made the nights oppressively hot. The difference was that we powered the air conditioners through two household batteries tucked away unobtrusively in the corners of our living room and bedroom.

We were among about 1,000 New York City households that took part in a free and growing program offered by the local startup Every Electric. The company’s proposition is simple: Get one or more batteries delivered to your home, plug the batteries into a standard wall electrical outlet, and then plug your window air conditioners into the batteries. Households can keep running air conditioners as usual during peak demand periods while also earning money through the local demand response program with the utility company Con Edison.

“Being able to make air conditioners drop off the grid without actually impacting the comfort of residents was really awesome to see,” said Andrew Wang, co-founder and CEO of Every Electric, in an interview with Ars.

Wang and cofounder Richard May first met while working together as postdoctoral researchers at the Columbia Electrochemical Energy Center at Columbia University in New York City. In 2023, they launched the startup under the name Standard Potential Co., with a focus on developing sodium-ion battery chemistry for commercialization.

But they soon pivoted to a very different business plan—deploying residential batteries across New York City households to create a network of energy storage resources acting as a virtual power plant. The company officially rebranded as Every Electric in 2026.

Getting set up

Many companies have established virtual power plant programs to offer utility companies greater flexibility and resources for managing electricity demand on the grid. Every Electric stands out for piloting a free power bank program that loans batteries to apartment renters and other households in exchange for a temporary deposit, which the company has reduced from $50 to $30 per battery.

The deposit is returned when a household decides to send the batteries back. Customers can also purchase the batteries outright for $650 each.

The battery delivery and setup process is straightforward. When the drop-shipped batteries arrived in their boxes, I plugged them into the appropriate wall sockets and followed a simple process to register the battery serial numbers with Every Electric and connect the batteries to my home Wi-Fi network.

Once connected to a local household’s Wi-Fi, the batteries act as power banks that automatically charge during low-demand periods at night and discharge their energy storage when air conditioners are running during peak demand periods. Every Electric automatically manages the battery cycles remotely.

Customers eventually get paid through Every Electric online accounts linked with Con Edison’s Smart Usage Rewards program. Every Electric gets paid directly by Con Edison as a program partner and, in turn, generally promises residents can earn $150 each year per air conditioner.

“There’s a business model innovation here where you make [household batteries] as easy and as accessible as possible, you get them as far and wide as possible, and then you essentially share in the value that you provide in the grid,” Wang told Ars. “We split the earnings so that households can see tangible benefits, and then we pay off the assets and grow the program as it goes along.”

Using the battery

Every Electric’s battery of choice is the Bluetti Elite 200 V2, a lithium iron phosphate battery that can store 2 kilowatt-hours of energy while being compact enough for smaller New York apartments. It's compatible with any 120V plug-in air conditioner, but it has four standard AC sockets that can also accommodate other appliances such as plug-in fans or air purifiers.

Additional battery sockets can charge laptops, smartphones, and other electronic devices that have power cables using USB-A or USB-C connectors. A 12V DC outlet in the style of a car’s cigarette lighter is also available.

The batteries can even provide backup power during power outages. For example, households can plug their Wi-Fi routers or refrigerators into the batteries to keep those devices running.

One bonus has been the discovery that feline family members of various New York households especially enjoy hanging around the batteries. “We found out cats are big fans of the powerbanks,” Wang told Ars. “I think it’s because they’re a little warmer.”

Despite such upsides, there have been a few kinks to work out during peak demand periods. When the utility company Con Edison had to reduce voltage for hundreds of thousands of customers across New York City to protect grid equipment during extreme heat periods, the power draw from the batteries tripped my apartment unit’s circuit breaker on two separate occasions.

Every Electric’s team responded by continually updating the battery firmware to reduce the risk of tripping local circuit breakers. That challenge can vary depending on each customer’s building.

“Every household is unique, and sometimes you have pre-war buildings with old wiring,” Wang told Ars. “You have to manage both some of the losses that are on the ConEd side and then some of the losses that might be in the wiring in people's walls to finetune how we operate the power banks to fit within the parameters of each household.”

From dozens to thousands of batteries

The company initially deployed 100 batteries across 65 households in the first test run in the summer of 2025. This year, it scaled up deployment to 2,000 batteries across about 1,000 households, providing the total equivalent of four megawatt-hours of energy storage during the summer of 2026.

“If you picture one of the big utility-scale, containerized batteries, one of those blocks is usually four megawatt-hours,” Wang explained. “So we've sort of taken that up and broken it up into 1,000 pieces spread across the city.”

This approach opens the door for distributing residential batteries to many more households by making inroads into the largest US city with more than 2 million rental homes. And more than 80 percent of New York City housing was built more than 50 years ago, meaning that they typically rely on window air conditioners without central air conditioning.

But not every initial customer has been an apartment dweller—early adopters also include residents of single-family homes in the New York City boroughs of Queens and Brooklyn. Some residents have even paired the batteries with plug-in solar panels to make the most of combining household energy storage with renewable power.

Whatever the home configuration, Every Electric’s program has proven popular in its first two years. The wait list grew to requests for more than 15,000 batteries this past summer—and Every Electric is aiming to scale up to more than 10,000 deployed batteries in 2027.

Every Electric remains focused on New York City as its home court. But as the battery network grows, the startup is also exploring new ways for Con Edison and other utility companies to get value from the distributed energy storage system beyond just participating in the demand response program.

“We have new utility territories that are coming to us—they're seeing that you can drop-ship literal megawatt hours to customers as a solution,” Wang said. “So we're certainly looking at how to map this model onto new markets.”

Siri AI Class-Action Lawsuit Settlement Website Is Now Live

1 Comment

Joe Rossignol, MacRumors:

In May, Apple agreed to pay $250 million to settle a U.S. class action lawsuit over Siri AI’s delayed launch, and the settlement website is now live.

Apple will pay an estimated $25 per eligible iPhone to eligible customers, who can submit a claim via the settlement website between September 21 and December 21 of this year. The exact payment may be higher or lower than $25 depending on the total number of valid claims submitted and other factors, with the maximum amount set at $95.

Apple denies all of the allegations made in the lawsuit. Apple agreed to the settlement to avoid the costs and risks of a trial.

I went ahead and filled it out for the iPhone 16 Pro I purchased in September 2024. I’d call it borderline whether it was worth my time for $25. It was a pain in the ass every step of the way.

For the eventual payment, your choices to receive the dough are PayPal, Venmo, ACH (bank transfer), or check. I tried to get it via PayPal and it just wouldn’t complete the connection to my PayPal account. After wasting time on a few tries, I tried ACH next, and the web form had pasting disabled on the fields for the routing and account numbers. Ridiculous. I was able to get around that to paste the numbers in, because I use StopTheMadness. But most people don’t. The only reason I can think of that they try to block pasting on those fields is to make it difficult.

Introducing the Safari MCP Server for Web Developers

1 Comment

Saron Yitbarek, writing on the WebKit blog, with a nice post-WWDC surprise:

In Safari Technology Preview 247, we’re introducing the Safari MCP server — a Model Context Protocol server for web developers that makes your web development and debugging workflow faster and more powerful. We know agents are increasingly integral to the coding process and the Safari MCP server gives your agent the ability to know how your code actually renders in the browser by connecting it to a Safari browser window.

Any MCP-compatible client can connect to the Safari MCP server. By connecting your agent to a Safari browser window, your agent can emulate what your users experience, giving it the information it needs to debug more autonomously, like access to the DOM, network requests, screenshots, and console output.

MCP is Anthropic’s open protocol, so it was designed for Claude, but all sorts of other tools use it too — Gemini CLI, Cursor, GitHub Copilot, and more. MCP really is open, not “open”.

★ Om

2 Comments and 3 Shares

John Gruber and Om Malik, sitting in the audience, smiling, at the WWDC 2025 keynote.

Om died two days ago, after a long battle against a bum heart.

Om and I often sat next to each other at Apple keynotes. This was not at all surprising or odd, insofar as we’d been friends for 20 years. Folks at Apple PR knew that we were close, and would often pair us together in post-keynote media briefings. I always enjoyed being paired with him. He asked keen questions. He saw through bullshit. He found holes in arguments. He took everything in. When I felt overwhelmed, he seemed serene. Om always seemed serene, period. His own photography reflects his presence.

Also, he was funny and fun. Profoundly generous. A good person to be around. A great person to know and be known by. He knew everyone and everyone knew Om. A lot of the people I know in this racket, I know through Om. Every time he’d introduce me to someone, he’d embarrass me with praise for my work. He greeted everyone with a compliment and whatever he said, he meant it. He had kind words to offer everyone because he had a gift for recognizing good things about everyone. He didn’t have an insincere bone in his body, which made him intensely lovable as a friend, and fiercely acerbic and accurate as a critic of technology. “He did not mince words” and “Everyone loved him” do not usually apply to the same person. They did with Om.

He was, of course, a Yankees fan.

So, no, it was not odd that he and I gravitated toward each other at Apple events. But the fact that Om continued to be invited to these events, with a media badge, was in fact unusual. He had stepped away from day-to-day journalism and became an investor back in 2014. A decade later, he was still on the short list of top invitees to events at Apple. His reputation warranted that respect. His ongoing writing and analysis — right up until the very end — continued to earn it. So of course Om continued to be invited to, and attend, these events. He was Om Fucking Malik. His presence improved any room, and lifted everyone’s mood. He made grumps smile. You couldn’t help it.

Om Malik, John Gruber, and John Siracusa, eating lunch at Apple Park after the 2024 WWDC keynote.

When he stepped aside from his namesake website GigaOm in 2014, Om wrote:

“Now it is time for the next chapter,” wrote Derek Jeter, the New York Yankees shortstop and my 2nd favorite Yankee (behind Bernie Williams), sharing his intention to retire at the end of 2014. “I have new dreams and aspirations and new challenges. And I want the ability to move at my own pace, see the world and finally have a summer vacation.”

I relate to Jeter’s desire to find life outside of work. Living a 24-hour news life has come at a personal cost. I still wake in middle of the night to check the stream to see if something is breaking, worrying whether I missed some news.

It is a unique type of addiction that only a few can understand, and it is time for me to opt out of this non-stop news life. After five years as a “venture partner,” I am joining True Ventures as a partner, and thus bringing an end to my life as a professional journalist.

Om, somehow, went straight from new-media wunderkind to éminence grise of tech journalism. Back when he was blogging, he blogged hard — multiple breaking-news posts per day, every day, while he was working as an acclaimed reporter for Business 2.0, Forbes, and Red Herring. That’s not what he did for the latter half of his career at all. He began changing his pace and perspective after suffering a heart attack in 2008, at the age of 42. He knew what he wanted to change, he told us, and then he did it. Thinking about his career transformation brings to mind the great Donald Knuth’s remarks regarding email:

Email is a wonderful thing for people whose role in life is to be on top of things. But not for me; my role is to be on the bottom of things. What I do takes long hours of studying and uninterruptible concentration. I try to learn certain areas of computer science exhaustively; then I try to digest that knowledge into a form that is accessible to people who don’t have time for such study.

What email is to Knuth, the 24-hour news cycle was to Om. He’d had enough, and recognized it. He no longer wanted to be on top of things. He wanted to be on the bottom of things. He transformed himself from the bloggiest of quick-trigger bloggers into the most thoughtful of essayists. He went from documenting what was happening, as it happened, to explaining why.

Om Malik, standing in a ray of sunshine in the hands-on area at Steve Jobs Theater in September 2024.

I texted him on June 1 to coordinate meeting up at WWDC the next week. That’s when he filled me in that he’d been hospitalized in the ICU at Stanford since mid-April, and the situation was dire. He needed a heart transplant or he wouldn’t live. I knew he’d been dealing with health issues in recent years, but I had no idea it had become so acute. We’d been chatting regularly for weeks — largely because he’d been so prolific of late, on topics exactly aligned with my own recent attention. He’d been doing some of the best writing and analysis of his career this year — but for the last few weeks, unbeknownst to me, and most of the world, that writing was from a bed in the ICU.1 This is going to sound cornier than a bucket of Jiffy-Pop, but it is a profound irony that a man with such a big and beautiful figurative heart could have such a lousy literal one.

I apologized for calling out his website in my “What Is a Dickover?” interactive essay, which I hadn’t warned him about, and had posted just three days before he told me of his medical plight. He told me not to worry, I was right, it was annoying, and he’d fix it. I didn’t think he’d get to that. But I checked today, and it’s gone.

Om didn’t keep his health crisis secret, per se. He kept it private. That was very Om. He was generous and effusive, often ebullient, always intense. But he was, in many ways, inscrutable. Private. Contemplative. Comfortable with himself, and by himself. I’ve never met anyone like Om Malik. They broke that mold after minting one.

I seldom ask anyone for professional advice, but when I did, I often asked Om. We did not do exactly the same thing, he and I, but we did close to the same thing. He understood what I do — or at least, what I try to do here — in a way that few others could. Among those of us who came of age in the first decade of blogging, who aspired to make it a career, the common route was to go from independent blogging to a salaried byline at an established big-name publication with roots in print as a magazine or newspaper. Om went the other way — from acclaimed reporter in top-shelf print magazines to turning GigaOm into a phenomenon. I never saw Daring Fireball as a stepping stone to greater things. I wanted only to make Daring Fireball a great thing. Om recognized that. In one of my earliest memories of meeting him — I think when I was working at Joyent, circa 2006 — we discussed publishing and new media and my own ambitions. He told me I should just keep doing what I was doing. Establishment media was a bloated slow-moving mess, he said. The future, he was absolutely certain, would be controlled by creators building their own brands and reputations, not subserving a legacy media publication. I told him I had no such plan. He said, “Good. You don’t need them. They need you.”

Om Malik, Matt Mullenweg, and John Gruber at Yankee Stadium for the AL wild card game between the Astros and Yankees, 6 October 2015. Only one of us was happy with the game's outcome.

Om loved good coffee, nice watches, exotic pens, Apple products, the media industry, photography (both the art and the gadgetry), and the New York Yankees. So, yeah — he and I always had more to talk about than time to talk when we were together. Always. But it was the Yankees we talked about most. He loved about the Yankees what I love about the Yankees — that they embody the pursuit of excellence. Not just winning, but winning the right way. The Yankees play in Yankee Stadium, not Shitco Cellular Service & Financial Bank Park. He got angry about the Yankees by what gets me angry about them. Not when they merely lose. That’s baseball. But when they get cheap, or stupid, or both. (You did not want to get Om started on Hal Steinbrenner, who is definitely cheap and possibly stupid.)

We attended a handful of games together at the Stadium. One time, he told me the most amazing story. When he first immigrated to New York in 1993, and was hustling to make a career in journalism in the U.S., he supported himself with a job selling luggage across the street from (old) Yankee Stadium in the Bronx. If you’ve ever been to New York, you know those stores. He worked at one. He didn’t know anyone in New York, let alone anyone in the U.S. business or technology news media. And he didn’t know a damn thing about baseball. So, on many days, he’d work all day and into the early evening, and then go across the street and buy a cheap seat in the upper deck and watch the Yankees. You’re never alone in a stadium. He learned baseball, and he fell in love with the Yankees on the cusp of the remarkable Jeter-Rivera-Pettitte-Posada dynasty. Om’s favorite player of that era was the serene Bernie Williams, of course. (Mine was Paul O’Neill, the hothead. Of course.)

I said, “I’ve always wondered about those stores. There’s so many of them. Does anyone actually buy luggage at those places?”

“John, you would be surprised. But they do not sell themselves. You have to sell them. It is hard work. The people who buy suitcases in those stores buy them there because they want to argue about prices. It is a fight every day.”

In Om’s telling, the threads were all infused. His lonesome isolation as a young immigrant, 7,000 miles from his birthplace. Falling in love with baseball (in general) and the Yankees (in particular) at just the right time — a crash course in American culture and an antidote to loneliness, rolled into one pinstriped package. His burning ambition to break into major U.S. journalism. And the daily humbling grind of selling suitcases on the hot summer sidewalks of the Bronx.

Om, from behind, taking a photo at Steve Jobs Theater, in September 2024.

Om didn’t sell suitcases for long. But I’ll bet while he did, he was pretty fucking good at it. He didn’t wait for his future to arrive. He made it happen. Careers — hell, our entire lives — are like those suitcases. They don’t sell themselves.

He not busy being born is busy dying, wrote Dylan. Om Malik wasn’t busy dying even when he was dying.


  1. I will forever be thankful that, somehow, I had the inkling to tell Om how good his recent writing was, before he told me his health was in such dire straits. Don’t hold back on telling people they made something you love or admire. Om himself was remarkably generous in that regard. ↩︎
