DARPA plans 30-year endurance nuclear waste batteries to power next-gen drones, says report — project SYMPHONEE aims to harvest Strontium-90 to power persistent military drones

1 Comment

Batteries that can last decades between recharges or renewals are the stuff of tech enthusiast dreams. However, DARPA’s ‘Rads to Watts’ program could bring forth unrivaled portable power, lasting decades, via the development of a new class of radiovoltaic devices. Morgan State University recently won a $3.37M DARPA contract to advance this tech, and a report by Defense One suggests upcoming nuclear waste-powered batteries could last as long as 30 years and power next-gen drones.

Morgan State now has a considerable sum to keep its researchers employed on a project dubbed SYMPHONEE (Strontium-Yttrium Multi-junction PIN-based High-Density Output Nano-system for Extreme Environments). Radioisotope power sources have been used for quite some time in low-power draw applications such as smoke detectors and space systems for decades. However, the new initiative, led by Morgan State and with team members such as Northrop Grumman, PNNL, Project Omega, ARA, and Widetronix, aims to take the tech into the next generation. More specifically, under the auspices of (and with funds from) the 'Rads to Watts' program, they are aiming to build next‑generation radiovoltaic micro‑power systems for extreme environments.

The proposed next-gen power cells make use of radioisotopes extracted from nuclear waste, especially Strontium‑90. Research partner Project Omega has already made some devices and will build the DARPA prototype. We noticed that it has published a promotional video that highlights sea drones with a 10-year battery life, for example. Coordinated by Morgan State researchers, PNNL labs will handle nuclear materials/testing, Northrop Grumman and ARA will provide AI-driven modeling, with Widetronix designing nuclear micro‑generator radiovoltaic converter architectures.

“Our team is pushing the boundaries of radiovoltaic technology, developing high-power, long-life systems that were not previously achievable,” said Professor Michael Spencer, the technical lead for the project. “By integrating advanced materials, device engineering, and nuclear science, we are laying the foundation for a new generation of persistent power systems for extreme environments.”

With this research, development, and fabrication powerhouse assembled, it is hoped a step change will be achieved to boost radiovoltaic micro‑power system power density. The goal is to be able to power persistent autonomous operations in remote or difficult-to-access environments like space, underwater, and contested regions – for decades. A Northrop Grumman rep emphasized the potential of a ‘persistent power source’ becoming available for “next-generation defense systems.” Project Omega is also interested in developing “persistent underwater security systems” – sea drones.

It is also somewhat positive to imagine that substances long considered to be highly undesirable waste products could end up being strategic assets.

Good thing there's no way that flying radioactive waste around could possibly end badly.

Free The Icons

1 Share

With last year’s release of MacOS 26 (Tahoe), Apple made a mess of app icons. In the first betas of MacOS 27 (Golden Gate), however, there are signs of a turnaround. We’re urging Apple to continue making improvements, by restoring the ability for MacOS app icons to have distinct shapes.

Apple’s Liquid Glass App Icons

In Tahoe, Apple modified the icons for dozens of their first-party apps to give them a “Liquid Glass” appearance. The changes were a substantial regression, leading to blurry, dumbed-down icons.

Two Automator icons, one pre-Tahoe with a detailed robot and one on Tahoe, with a hard-to-distiguish robot face.

With the recently unveiled Golden Gate, Apple has again updated their MacOS app icons. This time, however, the changes are genuine improvements. Here’s the refined Automator icon, for example:

The newer icon is sharper, with superfluous Liquid Glass removed. Dozens of Apple’s apps have seen similar updates. The result is that Golden Gate’s icons are superior to Tahoe’s, as this comparison from Basic Apple Guy shows. Seeing these improvements led me to think about another fix Apple should make in MacOS.

The Problem of Tahoe’s Dictated Squircles

With the Tahoe release, Apple didn’t just mess with their own icons. They also dictated the shape of every third-party app icon, forcing them to adopt the same prescribed squircle. Any icon that failed to do so found itself shrunk down and imprisoned in an ugly gray background, in order to fit Apple’s desired aesthetic.

To avoid this icon jail, developers were forced to redesign their icons to match Apple’s preferred form. After decades of beautiful, memorable Mac icons in varying shapes, Tahoe flattened personality to obtain bland uniformity. The platform is worse for it.

Past icons weren’t just more expressive. They were also more usable. Having distinct shapes provided a useful way to tell icons apart. Tahoe eliminates that cue by forcing everything into the same squircle, leaving color as the primary way to tell icons apart at a glance.

That falls down if you’ve got color vision deficiency, or even just multiple icons with similar color schemes.1 I’m looking at you, Slack and Photos. I have to look closely, because it’s so difficult to tell you apart now.

It Doesn’t Have to Be Like This

Apple’s prohibition on shapes is a step backward for both usability and creativity in app icons. Icons are now harder to distinguish because they’re no longer allowed to be distinctive. But there’s no technical reason for it. Apple could, and should, once again allow icons to take on a wide variety of shapes.

It’s clear that some people within Apple recognize that the transition to Liquid Glass introduced mistakes. They also appear to have the authority to fix those mistakes. Refinements to Apple’s own icons in Golden Gate are a welcome course correction, as is the much-celebrated Liquid Glass opacity slider. It’s time to correct the mistake of banning icon shapes as well.2

Apple should stop forcing every icon into the same squircle. Let’s return to a world of gorgeous app icons like these:

Free the icons.


Footnotes:

  1. With color now so critical to tell icons apart, it should be no surprise that the new “Clear” and “Tinted” icon styles added in Tahoe are seeing so little uptake. As Adam Engst noted, “[I]t’s nearly impossible to identify a particular app when they’re all clear or tinted squircles, as you can see below. My brain just shuts down when it sees them.”

    A sea of identical-looking icons on Tahoe, all tinted blue

    I’m not sure this “Tinted” style would be a good idea even if these icons had distinct shapes, but I know it’s a very bad one given their uniformity. ↩︎

  2. For folks within Apple, this was feedback filed as FB23388490 (“Third-Party App Icons Should Not Be Restricted to Apple’s Dictated Squircle Shape”). I imagine it is a duplicate many times over. ↩︎

Lilbits: 8TB SD cards are coming soon (likely for a small fortune)

1 Comment

It’s been more than two years since SanDisk announced plans to launch 4TB SD cards based on the SDUC standard. They haven’t actually arrived yet, so take this next part with a grain of salt, but during the Computex show in Taiwan earlier this month, SanDisk indicated that those 4TB SDUC cards really are coming […]

CEOs Who Think AI Replaces Their Employees Are Just Bad CEOs

2 Shares

In the last three months I’ve had people forward me four separate examples of a CEO losing his or her mind over AI. What’s been striking to me is the similarity in each case: It would be an “all hands” email in which the CEO talks up how amazing LLM tools are and saying that everyone in the company MUST start learning to use them immediately or they should look for a job elsewhere. Sometimes they talk about hiring “consultants” to come in and teach the team how to use the tools properly. Sometimes they are setting up “office hours” or internal “AI hackathons.”

But in every case the gist is the same “holy shit AI is amazing and you are expected to use it at your job all the time.” The worst case of these were the few companies that set up token leaderboards, which is perhaps the dumbest way possible to encourage learning how to use LLMs well. Good usage of AI includes learning how to view tokens as a scarce resource. Simply counting how much you use as a good thing is ridiculous because it’s incredibly easy to waste tokens on counterproductive uses.

As regular readers of Techdirt know, I actually do think that these tools are powerful and important, but I also think there are many problems with them and limitations to how useful they really are. I think when someone learns how to use them well and willingly chooses to use them as a tool to assist their work, they can be quite powerful. But the willingly choosing to use them part of that is important.

No one who is forced into using these tools will ever learn to use them well.

So CEOs losing their minds over the tech are not being helpful. Box CEO Aaron Levie — himself a genuine AI believer — puts his finger on exactly why.

CEOs are uniquely prone to AI psychosis because they’re sufficiently distant from the last mile of work that still has to happen to generate most value with AI.

So when they play with AI, they see the happy path results, often not considering the next 10 or 20 things that have to happen to get sustainable results from agents.

“Look I made this awesome product prototype”. Yes but you didn’t have to review the code before it went into production and fix a bunch of issues.

“Look I generated a contract”. Yes but you didn’t verify all the terms before it goes out to the counterparty and didn’t have to wire up all the past contracts to work with.

The best thing you can do as a CEO is to use AI a ton to figure out the real implications of agents in the enterprise, and come out the other side with an appreciation for both the upside and the real work that goes into them.

I will say that I hate the term “AI psychosis” because the term is extremely misleading, and many psychologists and psychiatrists have complained that it is inaccurate and may cause more problems itself. But the general sense that CEOs are going overboard with AI is definitely happening.

And I think Levie’s thinking as to why is also dead on.

Much of the issue may be in how disconnected the traditional CEO is from the people at a company actually getting stuff done. Normally, they have teams and layers and the actual work of getting things to work in a real way is so far removed from a CEO that they just get snippets of the details that filter back through the various org charts.

The problem tends to show up when a CEO is handed an agentic tool like Claude Code, and has it create something, which will work just fine, and thinks “oh, wait, why do we need so many people, when I can just sit here and make things work?”

This is a bad CEO.

Making things work is different than making things work well. Or well at scale. Or well at scale in a specific environment. Obviously, it depends on the kind of project and what it’s being designed to do, but oftentimes the reason a company has a bunch of employees is to fill in the seemingly small, but incredibly important details that CEOs might not ever get much visibility into: things like security or legal compliance or accessibility or who knows what else.

Using an agentic tool to build something that works is all well and good, but building a product for the mass market to use — and use well, and use safely — involves much, much more. Agentic coding tools can sometimes help with that too, but the leap from “I built a thing” to “therefore anyone can build a thing” misses the entire point of why you hire knowledgeable, experienced people in the first place. It’s also why I think the best case of these tools is building totally personalized tools to assist you in accomplishing a specific task, and not for building mass market tools.

This all reminds me of cargo cult thinking: The CEO knows that somewhere in the org, employees are pecking away at computers and work gets done. So they figure that themselves pecking away with Claude Code and seeing work get done is the same thing. It’s not. All those other steps those people are handling — the ones the CEO never sees — still need to happen.

That’s not to say employees wouldn’t benefit from a deeper understanding of both the power and the limits of these tools — they would. But there’s something darkly comical about watching a CEO go all in on the tech and then immediately conclude it means they can fire half the staff.

It seems pretty clear to me that companies that think they’ll be able to layoff huge swaths of workers because of LLM tools are going to find out they’re mistaken pretty quickly. The power of LLMs is that when used well and used willingly it can help employees to get more done, but that doesn’t mean you need fewer humans. You need more humans who know how to work productively.

Separately, companies pointing to LLMs as a reason for large layoffs are, in most cases, just using it as an excuse. They over-hired, and “AI efficiencies” is a much more palatable story for Wall Street than “we made bad headcount decisions.”

Levie’s prescription, though, is right: CEOs should learn how the tech works, but that includes the limitations of the technology. If a CEO thinks the prototype they vibe coded is production-ready, let them ship it and see what happens. If they think a vibe coded contract is as solid as one a lawyer reviewed, let them find out what the legal bills look like when it falls apart.

Yes, the tools are powerful, but a CEO who thinks they replace the work of employees is simply a bad CEO.
