Years after Twitter replaced the pistol emoji with a green-and-orange water gun, X has decided to change it back to a regular handgun. An X employee announced the change in a post last week.

Emoji are universal insofar as they share common designations across platforms (U+1F52B is the water pistol), which are decided by the Unicode Consortium. But it’s up to each platform owner to decide how they’re visually represented. That’s how we got the Great Cheeseburger Emoji Debacle that was resolved in November 2017.

You’ll only see the gun if you’re looking at X on the web — as of this writing, it doesn’t appear to have updated in mobile versions of the app, though that’s apparently on its way at some point.

In the world of heavy industry, change often comes at a glacial pace. But every once in a while, an innovation emerges that sends shock waves through the sector. Enter Hitachi Construction Machinery’s latest creation: the world’s first ultra-large, fully electric mining dump truck. This isn’t just another incremental improvement; it’s a game-changer that could reshape the future of mining operations worldwide.

Revolutionizing mining with zero emissions

Picture a machine as tall as a three-story building, capable of hauling over 200 tons of earth in a single trip. Now, imagine that this colossus runs entirely on electricity without a drop of diesel in sight. That’s exactly what Hitachi has achieved with their groundbreaking electric dump truck.

Developed in collaboration with ABB Ltd., a leader in electrification and automation, this electric titan represents the culmination of years of research and development. The project, which kicked off in 2021, aimed to tackle one of the mining industry’s most pressing challenges: reducing greenhouse gas emissions without sacrificing productivity.

The technology behind the electric dump truck

What sets Hitachi’s electric dump truck apart is its innovative charging system. Unlike electric cars that need to stop and plug in, this behemoth keeps on rolling thanks to a clever combination of overhead charging lines and regenerative braking.

As the truck moves along its route, it draws power directly from overhead lines, much like an electric train. Simultaneously, its regenerative braking system captures energy that would otherwise be lost during deceleration, feeding it back into the batteries. This dual-charging approach allows for continuous operation, eliminating the downtime associated with traditional battery charging.

The result? A mining truck that can operate for up to 20 hours a day, 350 days a year, matching the grueling schedules of conventional diesel-powered vehicles while slashing emissions to zero.

BULLET TRAIN-LOOKING GIANT SEMI TRUCK TO HIT US HIGHWAYS

From Japan to Zambia: The road to real-world testing

Hitachi isn’t content with proving their concept in controlled conditions. Instead, they’ve taken their electric dump truck to the heart of the mining world: First Quantum’s Kansanshi copper and gold mine in Zambia.

This choice of location is no coincidence. Zambia, with its abundance of renewable energy sources, provides the perfect backdrop for testing a zero-emission vehicle. The country’s energy grid, powered by hydroelectricity and an expanding portfolio of solar and wind projects, aligns perfectly with the ethos behind Hitachi’s electric truck.

Moreover, the Kansanshi mine already boasts an extensive network of overhead power lines for its existing fleet of trolley-assisted trucks. This infrastructure, coupled with the site’s varied terrain and real-world operating conditions, offers an ideal proving ground for Hitachi’s revolutionary vehicle.

MONSTER PLANE COULD REPLACE TRUCKS AND TRAINS

The impact: Beyond just another truck

The implications of Hitachi’s electric dump truck extend far beyond the confines of a single mine. If successful, this technology could pave the way for a dramatic reduction in the mining industry’s carbon footprint.

Consider this: a single one of these electric giants could eliminate the need for 1,200,000 liters of diesel fuel annually. That translates to a staggering 3,000 metric tons of CO2 emissions avoided each year per truck. Now, multiply that by the hundreds of trucks operating at major mining sites worldwide, and the potential for emissions reduction becomes truly monumental.

However, the benefits don’t stop at the environmental impact. The electric dump truck’s design, with its smaller battery pack and dynamic charging system, allows it to maximize payload capacity. This means more efficient operations, potentially leading to increased productivity and reduced operating costs for mining companies.

Looking to the future of mining

As the two-year trial at the Kansanshi mine unfolds, all eyes in the mining industry are on Zambia. The success of Hitachi’s electric dump truck could signal the beginning of a new era in mining operations, one where the roar of diesel engines is replaced by the quiet hum of electric motors.

This shift wouldn’t just benefit the mining industry. The technologies developed for these massive vehicles could find applications in other heavy industries, from construction to logistics. We might be witnessing the first steps towards a broader electrification of heavy-duty vehicles across various sectors.

Kurt’s key takeaways

As we watch this electric titan tackle the rugged terrain of Zambia’s copper belt, we’re not just observing a new piece of machinery at work. We’re witnessing the potential dawn of a new, cleaner era in mining. It’s a future where the extraction of Earth’s resources no longer comes at the cost of polluting its atmosphere. The road to a zero-emission mining industry may be long and challenging, but with each electric haul, Hitachi’s dump truck is bringing that future a little bit closer. And that’s something worth digging into.

TP-Link has debuted the Archer BE3600, a $99 Wi-Fi 7 router that is the cheapest one we’ve seen released in the US so far since the first routers supporting the new standard started arriving last year.

It doesn’t have the new 6GHz band like its pricier cousins or even many of the Wi-Fi 6E routers already on the market, though. As a result, for many people, TP-Link’s new router probably won’t get you your downloads a lot faster — if at all — than would a much older router.

The new tricks can mean a little throughput boost or a more stable connection than routers built to older specs in congested areas, though, thanks to the way Wi-Fi 7 handles its data streams. But without the one-two 6GHz punch of wider data channels and much more unoccupied space, you simply won’t see many of the multi-gigabit benefits hyped in Wi-Fi 7 marketing, and if you have a multi-gig internet connection, you should probably connect it to something a little more upmarket.

There are things to like here, though. Two of its five ethernet ports offer 2.5Gbps connections, which is rare at this price. It also supports Multi-Link Operation, which won’t be so much a throughput benefit (again: no 6GHz band) but could mean a more stable connection for a Wi-Fi 7-capable phone or VR headset — if one band fails or is too busy, your future device can fall back onto the other one. And it supports the Wi-Fi Alliance’s EasyMesh standard, meaning it can make mesh netwok with routers from other brands that also support the standard.

The most significant thing about this router seems to be that it offers Wi-Fi 7 for less than $100. That’s a first, and by a fair amount — the low end right now is otherwise generally around $300 (see TP-Link’s Deco BE63 or Archer BE550).
