Who says EVs can’t plow through water? A team of engineers, commercial divers, and enthusiasts successfully drove an electric retrofit Toyota LandCruiser across Darwin Harbour, an over 4 mile (7 km) trip. The EV was submerged entirely underwater, navigating depths up to nearly 100 feet (30 m).

Electric LandCruiser travels 4 miles underwater

You heard that right. The team converted a 1987 Toyota LandCruiser to an all-electric underwater powerhouse.

However, the story started 40 years ago when the same LandCruiser attempted the run but failed after hitting a rock less than 2 miles (3 km) in. The unfinished SUV project was bought for $5,000 (via Unsealed4x4), picking up the name “Mudcrab.”

Tom Lawrence, who launched the project, said it’s named the Mudcrab “because it’s orange and crawls along the bottom of the Darwin Harbor.”

Lawrence and others like Glen Summers, an electrical engineer, heard of the story growing up, which drew them to the project.

Three of the team members worked as electrical engineers in Silicon Valley, one being a former Tesla employee.

TV personality behind Aussie Salvage Squad, Luke Purdy, said the project was “the opportunity of a lifetime” and really three projects in one.

Meet the EV that traveled underwater

“First we had to build an electric car. Then build an underwater car and restore a LandCruiser,” Purdy explained.

Submerging a car comes with several hurdles, which kept the team busy “understanding the theory of what happens with pressure and what happens to oxygen underwater,” as well as keeping key components dry.

For this reason, the 37-inch tires are filled with water so they can handle the pressure of being nearly 100 feet (30 m) underwater.

The primary focus was to keep everything simple with one task in mind – crossing the Darwin Harbour underwater.

The electric LandCruiser is powered by a 32 kWh battery pack. Although that’s about half the average EV battery pack size, it’s enough to get the job done without adding too much.

Due to its instant torque, the electric motor can make it easier to move underwater than a gas-powered one. Meanwhile, the electric motor is a NetGain HyPer9, a popular choice for mid to light EV conversions.

The powertrain provides 88 kW power and 162 lb-ft of instant torque. Mounted on the front of the gearbox, the electric motor is protected from water with “innovative engineering techniques.” Purdy explained, “We basically put a garbage tin over the top of it and saturated it with silicon oil” to keep the electrons moving.

Not everything needed to be sealed. “The transmission and diffs can handle water,” Purdy said. “So we’ve gone for an open system because it’s easier.” Instead, the team opted to fill many drive components with food-grade grease to lubricate and keep seawater out of unwanted areas.

Once the electric LandCruiser was ready, it was time to send it underwater. A team of roughly 30 divers took turns driving the submerged EV for about 15 minutes each, reaching depths of up to nearly 100 feet (30 m).

The trip was anything but easy. The team entered Darwin Harbour around 9 a.m. Saturday, four hours later, barely clearing the descent with so much mud, silt, and sand swelling the Mudcrabs tires.

Using inflatable buoys chained to the car, the team lifted the car out of the mud each time. They expected to resurface around 4 p.m. to 5 p.m., but the journey took nearly 12 hours. But they did it, appearing before a cheering crowd around 9 p.m.

We don’t recommend this at home, but the Tesla Model S did float well enough to turn into a boat in this 2016 video.

Argonne Nat'l Lab is spending big bucks to study BIG hydrogen vehicles

Argonne National Laboratory is building a new research and development facility to independently test large-scale hydrogen fuel cell systems for heavy-duty and off-road applications with funding from the US Department of Energy.

The US Department of Energy (DOE) is hoping Argonne Nat’l Lab’s extensive fuel cell research experience, which dates back to 1996, will give it unique insights as it evaluates new polymer electrolyte membrane (PEM) fuel cell systems ranging from 150 to 600 kilowatts for use in industrial vehicle and stationary power generation applications.

The new Argonne test facility will help prove (or, it should be said, disprove) the validity of hydrogen as a viable fuel for transportation applications including heavy trucks, railroad locomotives, marine vessels, and heavy machines used in the agriculture, construction, and mining industries.

“The facility will serve as a national resource for analysis and testing of heavy-duty fuel cell systems for developers, technology integrators and end-users in heavy-duty transportation applications including [OTR] trucks, railroad locomotives, marine vessels, aircraft and vehicles used in the agriculture, construction and mining industries,” explains Ted Krause, laboratory relationship manager for Argonne’s hydrogen and fuel cell programs. “The testing infrastructure will help advance fuel cell performance and pave the way toward integrating the technology into all of these transportation applications.”

The Hydrogen and Fuel Cell Technologies Office (HFTO) of DOE’s Office of Energy Efficiency and Renewable Energy is dedicating about $4 million to help build the new Argonne facility, which is set to come online next fall.

Electrek’s Take

It’s going to be hard to convince me that the concentrated push for a technology as inefficient as hydrogen fuel cells has more to do with any real consumer or climate benefit than it does keeping the throngs of people it will take to manufacture, capture, transport, store, house, and effectively dispense hydrogen gainfully employed through the next election cycle.

As such, while case studies like the hydrogen combustion-powered heavy trucks that have been trialed at Anglo American’s Mogalakwena mine since 2021 (at top) and fuel cell-powered concepts like Komatsu’s medium-sized excavator (above) have proven that hydrogen as a fuel can definitely work on a job site level while producing far fewer harmful emissions than diesel, I think swappable batteries like the ones being shown off by Moog Construction and Firstgreen have a far brighter future.

Speaking of Moog, we talked to some of the engineers being their ZQuip modular battery systems on a HEP-isode of The Heavy Equipment Podcast a few months back. I’ve included it, below, in case that’s something you’d like to check out.

Velocity truck rental adds 47 high-speed truck chargers to California dealer network

Velocity truck rental is doing its part to help commercial fleets electrify by energizing 47 high-powered charging stations at four strategic dealer locations across Southern California. And they’re doing it now.

The new Velocity Truck Rental & Leasing (VTRL) charging network isn’t some far-off goal being announced for PR purposes. The company says its new chargers are already in the ground, and set to be fully online and energized by the end of this month at at VTRL facilities in Rancho Dominguez (17), Fontana (14), the City of Industry (14), and San Diego (2).

45 120 kW Detroit e-Fill chargers make up the bulk of VTRL’s infrastructure project, while two DCFC stations from ChargePoint get them to 47. All of the chargers, however, where chosen specifically to cater to the needs of medium and heavy-duty battery electric work trucks.

The company says it chose the Detroit e-Fill commercial-grade chargers because they’ve already proven themselves in Daimler-heavy fleets with their ability to bring Class 8 Freightliner eCascadias, Class 6 and 7 Freightliner eM2 box trucks, and RIZON Class 4 and 5 cabover trucks, “to 80% state of charge in just 90 minutes or less.”

At Velocity, we are not just reacting to the shift towards electric mobility; we are at the forefront with our customers and actively shaping it. By integrating high-powered, commercial-grade charging solutions along key transit corridors, we are ensuring that our customers have the support they need today. This charging infrastructure investment is a testament to our commitment to helping our customers transition smoothly to electromobility solutions and to prepare for compliance with the Advanced Clean Fleets (ACF) regulations.

David Deon, velocity president

Velocity plans to offer flexible charging options to accommodate the needs of different fleets, including both managed, “charging as a service” subscription plans and self-managed/opportunity charging during daily routes. While trucks are charging, drivers and operators will be able to relax in comfortable break rooms equipped with WIFI, television, snacks, water, and restrooms.

Electrek’s Take

While it feels a bit underwhelming to write about trucking companies simply following the letter of the law in California, the rollout of an all-electric, zero-emission commercial trucking fleet remains something that, I think, should be celebrated.

As such, I’m celebrating it. I hope you are, too.

This new $5,000 electric drone can carry you and your brave friends

This new ,000 electric drone can carry you and your brave friends

As I peruse Alibaba for all sorts of fun and interesting electric vehicles, I often stumble across seemingly outlandish products that often have a real use case behind them. The best of those make it into the recurring Awesome Weird Alibaba Electric Vehicle of the Week column, and that’s precisely where this man-carrying drone lands today.

To be fair, I’m not sure the main purpose of this flying EV is to carry people.

They do advertise it with a few images of a person suspended beneath it to show off the drone’s carrying capacity. And at least one of the photos seems like it’s actually non-recreational as the guy appears to be in the process of accessing a communications tower platform.

I guess for those who don’t want to spend half an hour climbing a ladder to change a light bulb or swap a connector, a drone might be a shortcut to some of these difficult access areas. It could also open up the worker pool for that job to not only people with Popeye’s forearms.

But manned work doesn’t seem like the main use case for a heavy-lift drone like this.

Instead, it appears to me that it’s primarily a work drone designed for utility tasks where you’d want to lift a serious amount of weight in tools or supplies.

The stated 200 kg (440 lb) weight-carrying capacity is quite impressive, especially since the unit only weighs 40 kg (88 lb) by itself. But you’ll want that extra lift potential for a number of its other advertised uses, such as a water sprayer for cleaning tasks or a heavy-lift drone for moving supplies in mountainous or otherwise hard-to-reach areas.

Some companies even seem to use them to clean wind turbine blades.

Interestingly, the drone can either run off of its 16 on-board batteries or can be tethered to an electrical cable for continuous flying. For longer duration jobs like window washing, that’s probably the better way to go.

The batteries only offer 20 minutes of flying time, and replacing 16 batteries with freshly charged units would probably take you another 20 minutes on the ground. That limited battery flight time also means that if you are going to use it to carry workers up onto aerial platforms, you better not take the scenic route.

The drone does come with three parachutes that can automatically deploy if it enters free fall, which makes me feel only marginally better about hanging onto that rope ladder and going for a ride.

The factory also advertises that the controls can be run tethered, so you don’t have to use radio frequency in areas where it might be jammed. That has me a bit worried about what other uses they’re envisioning for a heavy-lift drone like this, but I’ll leave that for another day.

How our resident Photoshop wizard imagines I’d look on one of these things

With an advertised price of US $5,000, it also seems weirdly affordable. I have no idea what the going rate for a man-lift drone is these days, but I probably would have guessed more than that. You can barely buy an electric motorcycle for that much, and those only move in a single plane.

Of course, the catch is that you have to buy two of them, as that’s the minimum order quantity from the seller. So if you’re crazy enough to strap into one of these things, you better find an equally crazy friend for the second one.

And in case it wasn’t yet clear, please don’t actually try to buy one of these from Alibaba. This column is a tongue-in-cheek exercise in exploring just how amazing and interesting the world’s largest EV provider’s catalog of wacky vehicles has become. But I am certainly not encouraging anyone to run the financial and emotional gauntlet of trying to buy something expensive on Alibaba. I’ve been there and done that, and it’s not for the timid.
