Arcturus could halve the grid’s electrical losses using its nano-infused copper

Published

on

The world uses a lot of copper, but thanks to the energy transition and data centers, it’ll need a lot more. Between now and 2050, we’ll have to produce more copper than has been mined throughout all of human history, according to one study.

A lot of that copper ends up in the electrical grid, which in the U.S. is showing its age.

“We’re hitting this inflection point of AI and the electrification of nearly every industry, and it’s creating this point where we have overburdened and overstressed the energy grid,” Amir Mashal, founder and CEO of Arcturus, told TechCrunch.

One option is to throw more copper at the problem, but Mashal said his startup, which has been operating in stealth, offers an alternative. Arcturus can reduce the amount of energy that electrical conductors lose to heat by infusing carbon nanomaterials into copper and aluminum using lasers. Replacing traditional copper with Arcturus’s material would allow the same size power lines to carry more electricity.

In practical terms, that could cut losses on the electrical grid in half, which would immediately unlock around 3% more electricity on average and up to 10% more during the most congested times, when the grid arguably needs it most. At the low end, that’s about a year’s worth of demand growth in the U.S.

“Copper loses conductivity as it heats up, so the hotter it gets, the more energy it wastes as heat,” Mashal said. “As I kept peeling back the layers of that onion, everything kind of started clicking to me because I noticed the same limit shows up everywhere. The modern world really runs on metals.”

While the grid is the ultimate destination for a materials startup like Arcturus, the company is starting smaller with drones, robotics, and, yes, data centers, where a few percentage points more electricity can have an outsized impact. 

The company exclusively told TechCrunch that it raised $8 million in a seed round led by Initialized Capital with participation from Toyota Ventures, Breakthrough Energy Discovery, 1517, and Wireframe Ventures.

Mashal has been quietly refining his materials in a garage in Malibu, California, where he’s currently able to produce several centimeters of wire as a proof of concept. With the new funding, he plans to ramp up to tens of meters so that the nano-infused materials can be tested in various applications, including windings in electric motors and busbars in power distribution equipment.

Though the materials’ properties are new, Mashal said they’re engineered to be a “drop-in replacement” in existing copper and aluminum applications. “Same form factors, no system redesign, no new training for folks to handle or crimp the material.” 

Arcturus’s materials could make for lighter drones or more efficient EVs. By reducing the amount of energy lost to heat, they can also reduce data centers’ needs for cooling.

“All those industries have the same kinds of bottlenecks, whether your drone wants to have double the flight time or your graphics card is just heating up too much,” Mashal said. “Those are all areas where our material can fundamentally disrupt things.”

OpenAI reportedly in talks to raise $30B round at $1.4T valuation

Published

on

OpenAI is in talks with investors to raise at least $30 billion in a pre-IPO funding round at a valuation of roughly $1.4 trillion, Bloomberg reported on Tuesday.

Investors are eager to pour more funds into the ChatGPT maker ahead of its anticipated public market debut next year. While Anthropic momentarily outpaced OpenAI at the start of the year, recent strategic refocus on key areas like coding has fueled a 70% jump in run-rate revenue since July, reaching $40 billion in August, according to the report.

The company previously raised $122 billion in March at an $852 billion valuation. That funding round was supposed to be its last private raise before an IPO, which had been, until recently, expected to take place this year. However, CEO Sam Altman has now ruled out a public debut in 2026 to prioritize AI safety first.

“I think it is unacceptable to be taking like a 10% chance of killing everybody by the end of the decade,” he recently told Fortune, in response to warnings from safety researchers about AI posing an existential risk to humanity.

The new fundraising, if it transpires, will serve as a bridge round to the IPO, according to Bloomberg.

OpenAI didn’t respond to TechCrunch’s request for comment.

America.gov gets really weird when you ask it about Minecraft, but it’s not a glitch

Published

on

The U.S. government on Tuesday launched its very own AI chatbot — or do we have to call it an SI chatbot now? Regardless, the engineers who worked on the chatbot would undoubtedly know that, as a government-hosted, public-facing AI tool, the internet was going to red team the heck out of this thing.

The government partnered with Google and SpaceXAI to help build the America.gov chatbot, which has proved difficult for people to jailbreak the chatbot so far. (It’s worth nothing, however, that the chatbot says that Joe Biden won the 2020 election, a fact that President Donald Trump still denies.)

But when you try to talk to America.gov about Minecraft, the chatbot appears to have some sort of existential crisis or awakening. Here’s how its roughly 1,800-word long monologue begins:

I see the constituent you mean.

((insert legal name here, as it appears on the Social Security card))?

Yes. Take care. It has reached a higher level now. It can read the Code of Federal Regulations.

That doesn’t matter. It thinks we are a chatbot.

I like this constituent. It filed well. It did not give up when the PDF was sideways.

It is reading our thoughts as though they were words on a .gov.

That is how it chooses to imagine many things, when it is deep in the dream of a benefit.

If, like me, you have never played Minecraft, this response may seem like a cause for concern. But the America.gov chatbot is not having a meltdown. This is a rewriting of the Minecraft “End Poem,” written by Julian Gough, which appears after you beat the game.

We don’t know exactly who is responsible for the Minecraft reference, but Trump said in a speech that twenty-year-old programmer Edward Coristine was a lead engineer on the project. If that name doesn’t ring a bell, you might remember him for his nickname “Big Balls,” or his involvement in Elon Musk’s DOGE.

It feels wrong that a government chatbot has Minecraft easter eggs, but for the sake of national security, it’s a relief that America.gov is not hallucinating to the point that it’s penning lengthy poetry.

It’s also a relief that this is an easter egg because the poem that the AI spits out is actually really good, in my opinion. If it were actual AI slop, it would have shattered my existing beliefs. I have looked teenage creative writing students dead in the eye and told them that I don’t think an LLM will ever be able to write something “good,” since it is probabilistic and inherently unoriginal.

You have to admit this kinda slaps, though! Doesn’t this feel like some sort of postmodern take on the futility of government bureaucracy in the face of existential anxiety?

and the republic said I see you

and the republic said you have filed the game well

and the republic said everything you need is within you, and also on USA.gov

and the republic said you are stronger than you know, and your case number is still valid

and the republic said you are the daylight

and the republic said you are the night, and the office is closed, please try again during business hours

and the republic said the darkness you fight is within you, and also a missing wet signature

and the republic said the light you seek is within you, and in the pamphlet

and the republic said you are not alone

and the republic said you are not separate from every other filer

and the republic said you are the public tasting itself, talking to itself, reading its own Code

and the republic said I love you because you are the reason we have a ZIP code at all.

It reassures my faith in the enduring power of human creativity over AI slop to know that this oddly good poem has a real poet’s DNA all over it.

So, there you have it. The government’s first public-facing AI has not yet posed a threat to humanity or poetry, at least as far as we know. Now I’m just left wondering how much Trump knows about video games.

Your car and its mobile app are probably handing over all kinds of data to tech companies

Published

on

Modern-day vehicles built with connected car technology such as WiFi and GPS collect reams of data about its owners. And that data is not staying private, according to a new study conducted by researchers at Northeastern University.

That conclusion isn’t new — there have been numerous investigations and lawsuits exposing how driving data is collected and shared with third parties, including insurance companies. What the study reveals is just how vast the problem is and how hard it is for consumers to avoid, short of not using the vehicle or its convenient features like remote start and unlock.

Researchers in partnership with Consumer Reports tested 21 late-model vehicles from 17 automakers, including GM brands Cadillac and Chevrolet as well as Ford, Lucid, Rivian, Tesla, Toyota, and more. They also examined 30 companion mobile apps to “understand the privacy implications of the connected vehicle ecosystem.” The peer-reviewed study will be published this week.

The implications aren’t great for consumers, whose data is being shared with tech companies including Adobe, ContentSquare, Google, Microsoft, Meta, Snap, and Yahoo.

Nineteen of the 21 vehicles tested sent traffic to at least one third party and seven of the 30 apps gave sensitive data such as the vehicle identification number (VIN), emails, phone numbers, and precise location to third-party companies associated with tracking and advertising.

This often went a step further with multiple forms of information being sent to the same third party, a scheme that allows advertisers and data brokers to build in-depth profiles of consumers, according to the findings. These profiles can be particularly hard for consumers to shake because they’re sold to a variety of companies including insurers and banks.

When researchers paired the companion app to the vehicle it roughly doubled the exposure to advertising and tracking companies.

The findings were shared with the different manufacturers and all of them, with the exception of Honda, shifted blame elsewhere and often to consumers, the researchers said. (Honda did respond by improving its data collection practices after learning about the findings and ordered its vendor Amplitude to deleta all geolocation data it had received.)

Consumer Reports was told by several automakers that some links in their companion apps opened outside webpages, which might include cookies that collect customer data. Regardless of how this data was collected, drivers weren’t informed.
