How Regulations Are Trying To Keep Home Battery Installs Safe

September 24, 2025 by Lewin Day 81 Comments

The advent of rooftop solar power generation was a huge step forward for renewable energy. No longer was generating electricity the sole preserve of governments and major commercial providers; now just about any homeowner could start putting juice into the grid for a few thousand dollars. Since then, we’ve seen the rise of the home battery, which both promises to make individual homes more self sufficient, whilst also allowing them to make more money selling energy to the grid where needed.

Home batteries are becoming increasingly popular, but as with any new home utility, there come risks. After all, a large capacity battery can present great danger if not installed or used correctly. In the face of these dangers, authorities in jurisdictions around the world have been working to ensure home batteries are installed with due regard for the safety of the occupants of the average home.

Who Wants A Rusty Old Smartphone?

If we’re talking about oxidized iron… probably nobody. If we’re talking about Rust the programming language, well, that might be a different story. Google agrees, and is working on bringing the language into Android. That’s not enough for [Paul Sanja], who has the first Redox OS smartphone.

Redox OS is a Unix-like operating system written entirely in Rust, and somehow we haven’t covered it until now. Unlike Asterinas, a project to recreate the Linux kernel in Rust, Redox has few pretensions of being anything but its own thing, and that’s great! On desktop, Redox has a working windowing system and many utilities, including a basic browser in the form of NetSurf.

It’s claims to be source-compatible with Linux and BSD programs, and partially POSIX compliant. A certain someone around here might want to try it as a daily driver. The header image is a desktop screenshot, because there’s more to see there and it fits our aspect ratio.

On smartphones, it… boots. Some smartphones, anyway. It’s actually a big first step. That booting is possible is actually thanks to the great work put in by the Postmarket OS team to get Uboot working on select android devices. That uboot loader doesn’t need to load the Linux-based Postmarket OS. It can be used for anything compatible. Like, say, Redox OS, as [Paul] shows us.

Of course, Redox OS has no drivers for the touchscreen or anything else, so at the moment that rusty smartphone can only boot to a login screen. But thanks to Rust, you can rest assured that login screen hasn’t got any memory leaks! Jokes aside, this is a great start and we’re hoping to see more.

Redox is a promising project on mobile or desktop, and its development seems a much better use of time and effort than fighting over Rust in the Linux kernel.

RTINGS 10-Year Equivalent TV Longevity Update With Many Casualties

For the past two-and-half years Canadian consumer testing outfit RTINGS has been running an accelerated aging experiment across a large number of TVs available to a North-American audience. In their most recent update, we not only find out about the latest casualties, but also the impending end of the experiment after 18,000 hours — as the TVs are currently failing left and right as they accelerate up the ascending ramp of the bathtub curve.

Some of these LEDs are dead, others are just wired in series. (Credit: RTINGS.com) — Some of these LEDs are dead, others are just wired in series.

The dumbest failure type has to be the TVs (such as the Sony X90J) where the failure of a single dead backlight LED causes the whole TV to stop working along with series-wired LED backlights where one dead LED takes out a whole strip or zone. Other failures include degrading lightguides much as with our last update coverage last year, which was when edge-lit TVs were keeling over due to overheating issues.

Detailed updates can be found on the constantly updating log for the experiment, such as on the failed quantum dot diffusor plate in a TCL QLED TV, as the quantum dots have degraded to the point of green being completely missing. Although some OLEDs are still among the ‘living’, they’re showing severe degradation – as pictured above – after what would be the equivalent of ten years of typical usage.

Once the experiment wraps up it will be fascinating to see who the survivors are, and what the chances are of still using that shiny new TV ten years from now.
