This zippy RC submarine lets you explore beneath the waves

OpenROV’s Kickstarter campaign for its new Trident underwater drone is now live, and the early sales are impressive. The campaign has absolutely exploded on Kickstarter, reaching its goal within five minutes of launch. With 44 days still left to go, the consumer-oriented underwater vehicle has raised $370,000, exceeding its original goal of $50,000 by a factor of six. According to OpenROV, the Trident has the versatility of a ROV (remote operated vehicle) and combines it with the efficient operation of an AUV (Autonomous Underwater Vehicle). And with a starting price of $599 for the Kickstarter “Super Early Bird Special”, it’s no surprise the drone is selling like mad.

The Trident isn’t OpenROV’s first drone.The company kickstarted another model, the OpenROV – Open Source Underwater Robot, back in 2012. The original OpenROV drone was sold a kit that contained all the parts necessary to build the underwater vessel. Using their experience and feedback from the enthusiast community, the OpenROV team went to work on Trident. Trident features a hydrodynamic design that is efficient at flying through in the water in long, straight runs, yet maneuverable enough to slide in between underwater rocks and crevices. It’s also smaller than its predecessor with a form factor that allows the drone to fit in a backpack.

The Trident is packed to the max with features that make flying in the water fun. The ROV can fly in long, straight lines when surveying an area or perform delicate maneuvers when needed to navigate in tight spaces. The drone also includes LED lights for underwater viewing and a built-in HD camera capable of capturing images or videos that can be used to create a 3D model of the ocean floor. Similar to OpenROV’s earlier drone, the software that powers the Trident is open source, allowing enthusiasts to add new features.

Right now the Trident is selling out quickly, with the $599 and $799 packages no longer available. Interested buyers can still grab the discounted $949 or full price $1,199 bundle that includes the drone, as as well as a neutrally-buoyant tether for sending telemetry data back to the surface and a wireless topside buoy.

EVs top gas cars in German reliability report — but one weak spot won’t quit

future electric cars 2021 volkswagen id4 official 32

Electric vehicles are quietly crushing old stereotypes about being delicate or unreliable, and the data now backs it up in a big way. According to Germany’s ADAC — Europe’s largest roadside assistance provider — EVs are actually more reliable than their internal combustion engine (ICE) counterparts. And this isn’t just a small study — it’s based on a staggering 3.6 million breakdowns in 2024 alone.
For cars registered between 2020 and 2022, EVs averaged just 4.2 breakdowns per 1,000 vehicles, while ICE cars saw more than double that, at 10.4 per 1,000. Even with more EVs hitting the road, they only accounted for 1.2% of total breakdowns — a big win for the battery-powered crowd.
Among standout performers, some cars delivered exceptionally low breakdown rates. The Audi A4 clocked in at just 0.4 breakdowns per 1,000 vehicles for 2022 models, with Tesla’s Model 3 right behind at 0.5. The Volkswagen ID.4, another popular EV, also impressed with a rate of 1.0 – as did the Mitsubishi Eclipse Cross at 1.3. On the flip side, there were some major outliers: the Hyundai Ioniq 5 showed a surprisingly high 22.4 breakdowns per 1,000 vehicles for its 2022 models, while the hybrid Toyota RAV4 posted 18.4.
Interestingly, the most common issue for both EVs and ICE vehicles was exactly the same: the humble 12-volt battery. Despite all the futuristic tech in EVs, it’s this old-school component that causes 50% of all EV breakdowns, and 45% for gas-powered cars. Meanwhile, EVs shine in categories like engine management and electrical systems — areas where traditional engines are more complex and failure-prone.
But EVs aren’t completely flawless. They had a slightly higher rate of tire-related issues — 1.3 breakdowns per 1,000 vehicles compared to 0.9 for ICE cars. That could be due to their heavier weight and high torque, which can accelerate tire wear. Still, this trend is fading in newer EVs as tire tech and vehicle calibration improve.
Now, zooming out beyond Germany: a 2024 Consumer Reports study in the U.S. painted a different picture. It found that EVs, especially newer models, had more reliability issues than gas cars, citing tech glitches and inconsistent build quality. But it’s worth noting that the American data focused more on owner-reported problems, not just roadside breakdowns.
So, while the long-term story is still developing, especially for older EVs, Germany’s data suggests that when it comes to simply keeping you on the road, EVs are pulling ahead — quietly, efficiently, and with far fewer breakdowns than you might expect.

You can now lease a Hyundai EV on Amazon—and snag that $7,500 tax credit

amazon autos hyundai evs lease ioniq 6 n line seoul mobility show 2025 mk08

Amazon has changed how we shop for just about everything—from books to furniture to groceries. Now, it’s transforming the way we lease cars. Through Amazon Autos, you can now lease a brand-new Hyundai entirely online—and even better, you’ll qualify for the full $7,500 federal tax credit if you choose an electric model like the Ioniq 5, Ioniq 6, or Kona EV.
Here’s why that matters: As of January 2025, Hyundai’s EVs no longer qualify for the tax credit if you buy them outright, due to strict federal rules about battery sourcing and final assembly. But when you lease, the vehicle is technically owned by the leasing company (Hyundai Capital), which allows it to be classified as a “commercial vehicle” under U.S. tax law—making it eligible for the credit. That savings is typically passed on to you in the form of lower lease payments.
With Amazon’s new setup, you can browse Hyundai’s EV inventory, secure financing, trade in your current vehicle, and schedule a pickup—all without leaving the Amazon ecosystem.
It’s available in 68 markets across the U.S., and pricing is fully transparent—no hidden fees or haggling. While Hyundai is so far the only automaker fully participating, more are expected to join over time.
Pioneered by the likes of Tesla, purchasing or leasing vehicles online has been a growing trend since the Covid pandemic.
A 2024 study by iVendi found that 74% of car buyers expect to use some form of online process for their next purchase. In fact, 75% said online buying met or exceeded expectations, with convenience and access to information cited as top reasons. The 2024 EY Mobility Consumer Index echoed this trend, reporting that 25% of consumers now plan to buy their next vehicle online—up from 18% in 2021. Even among those who still prefer to finalize the purchase at a dealership, 87% use online tools for research beforehand.
Meanwhile, Deloitte’s 2025 Global Automotive Consumer Study reveals that while 86% of U.S. consumers still want to test-drive a vehicle in person, digital tools are now a critical part of the buying journey.
Bottom line? Amazon is making it easier than ever to lease an EV and claim that tax credit—without the dealership hassle. If you're ready to plug in, it might be time to add to cart.

Humanoid robots race against humans at unique half-marathon in China

A humanoid robot running in a half marathon.

You may have seen robots dancing like the music icon Mick Jagger, doing parkour, or even painting on a canvas. Tesla’s Optimus humanoid robot is eagerly anticipated, while Google and Meta are also planning to enter the field. The competition in the East, however, is on a different level altogether.

China just put humanoid robots to the test in the world’s first race of its kind, where they ran alongside humans in a half-marathon. A total of 21 robots lined up for the event in the Yizhuang half-marathon, following a long spell of supervised learning on roads.
