Komatsu just launched its first-ever electric underground drilling and bolting rigs, signaling a new beginning for the Japanese construction giant’s hard rock mining portfolio.

Part of a broader range of updates and options for the second-generation of Komatsu‘s Z2 line of small-class development drill and bolting equipment that includes an innovative resin-pumping system, optimized cabin ergonomics for the operator, and more advanced telematics, the all-electric versions of the Komatsu ZJ21 jumbo drill and ZB21 are (like their predecessors) built on a common platform. That platform features a modular battery driveline that’s been specially designed to withstand the demanding duty cycles and challenging of hard rock mining.

“As underground mining operations increasingly shift toward electrification of their fleets, our innovative, battery-powered Z2 jumbo drills and bolters will support that pivotal transition. By integrating into existing infrastructure, we can help enhance productivity while helping to reduce operating costs,” said Johan Kempe, product director for underground drilling at Komatsu. “The rollout of our second generation Z2-class marks a milestone in our commitment to advancing mining technologies and building upon the proven success of our products to empower the future of mine operators.”

The new Komatsu ZB21 is a small-class bolter featuring a fully enclosed ROPS/FOPS-certified operator cabin with updated operator controls, integrated screen handling, and industry-leading drifters manufactured by Montabert.

The second-generation bolter also introduces an optional pumpable resin system using J-LOK P developed by Jennmar. Komatsu says this unique solution pumps into the drilled hole prior to bolt installation, permitting the use of more economical (read: cheaper) bolts and driving down overall project cost.

The updated ZJ21 jumbo drill, which shares a number of modular components with the ZB21, features a similar operator cabin, innovative drilling feeds, advanced pilot hydraulics, and the same, new Montabert drifters.

Both vehicles feature an 83 kWh li-ion battery pack presumably developed in concert with American Battery Solutions (ABS), which Komatsu acquired late last year. That purchase was part of a company-wide effort to help Komatsu achieve its stated ESG goals. Those being: a 50% reduction of CO2 emissions from the use of its products by 2030 (compared to 2010 levels) and company-wide carbon neutrality by 2050.

Electrek’s Take

Komatsu says its BEVs are designed to increase productivity compared to diesel through a mix of onboard charging, smart opportunistic charging capabilities, and 100% compatibility with existing infrastructure (translation: your accessories will fit). As for whether or not its new EVs will deliver – well, it’s hard to argue with Komatsu engineers. They’re smart, they’ve done the math, and they’ve built lithium-powered EVs specifically to mine for more lithium (again: smart).

Here’s hoping we get to read about more EVs from Komatsu sooner than later, then.

The Invanti Tornado is the Swiss Army knife of e-bikes [Video]

Want your electric bike to have utility as well as comfort and style? Then, the Invanti Tornado, with its impressive array of optional accessories, could be your ideal ride.

Invanti is developing multi-functional e-bikes to reinvent the e-bike industry. It will launch an Indiegogo crowdfunding campaign on May 22 for its first product, the versatile Tornado e-bike series. Early backers can purchase the Tornado for a super early bird price of $1,299, significant savings vs. gas bikes.

Invanti makes it easy to protect your e-bike from theft with its “invantimobility” app. The smart version Tornado Pro has a smart front hub lock feature that, once activated, can only be unlocked using the app.

This zippy and efficient utility e-bike has a 750W rear hub motor, 1,000 peak power, and a 48V 14.7Ah battery with Samsung cells that give a top speed of up to 25 mph. The Shimano 7-speed transmission, 80 mm travel suspension, 4-piston hydraulic disc brakes, and torque sensor means riding is smooth. It also sports a pair of 20-by-3-inch puncture-resistant tires.

The Tornado provides a range of 60 miles on pedal assist and 25 miles on throttle only. You can additionally install an extra 48V, 10.4Ah battery that you take with you, giving a cumulative total of 100 miles on pedal assist and 43.5 miles on throttle only. Plus, you can use the extra battery as a portable powerbank for your phone.

What makes the Invanti Tornado stand out is the cool accessories it comes with. Your e-bike arrives with a front rack, a rear cargo rack, a rear fork storage bag with lockout, and rear wheel mudguards. It also features front and rear lights with integrated turn signals.

Plus, it offers a choice of nine upgrade accessories, which give this bike an almost modular feel. This means you can make your e-bike bespoke:

If you want to cart around passengers, you can make it happen with the Invanti Tornado’s optional rear seat pad and passenger foot rest, and there’s also a child safety handrail. Its dual-tube aluminum alloy frame can handle payloads of up to 440 pounds.

Invanti’s super early bird price on the Tornado is $1,299, and the official crowdfunding price is $1,499.

This startup is about to install bladeless rooftop wind turbines on box buildings

Aeromine Technologies just closed a $9 million funding round, and it’s ready to scale up production of its bladeless rooftop wind turbines.

Energy research, investing, and strategy firm Veriten is the lead investor in Aeromine Technologies’ Series A funding round.

Aeromine, launched in 2022, makes compact 50 kW or larger “wind harvesting platforms” that it mounts on the edge of a building’s roof. The rooftop wind units, which have no external moving parts or blades, capture wind flowing up and over the building and convert it into onsite electricity. Its generator system is a rotor-stator system with a highly efficient 5 kW permanent magnet generator. (Specs are here.)

The noiseless technology leverages aerodynamics like airfoils on a race car to capture and amplify each building’s airflow to generate energy. Aeromine says its systems typically consist of 20-40 units installed on the edge of a building facing the predominant wind direction.

Each 1,000-pound unit can withstand winds of between 120 and 158 mph depending on specification.

Aeromine’s units can operate independently or be integrated with existing rooftop solar arrays. Onsite power generation eliminates grid supply disruptions.

Maynard Holt, founder & CEO of Veriten, said:

We believe that distributed power innovation will play a vital role in helping companies fulfill their need for reliable, reasonably priced electricity and desire for low-impact power. We’re excited to partner with Aeromine, as its ability to quickly and affordably help a wide variety of companies meet their energy needs with wind resources is unique among distributed energy solutions.

The bladeless wind turbines are designed to power apartment buildings, warehouses, manufacturing facilities, offices, hospitals, retail centers – basically any big box building with a flat, unobstructed roof.

The company says it has 400 qualified projects in its pipeline and expects to roll out commercially in Europe and North America in 2025.

Ford likely to enable all dealers to sell EVs amid shifting plans

Ford likely to enable all dealers to sell EVs amid shifting plans

With changes expected to Ford’s electric vehicle certification program, all Ford dealers will likely be able to sell EVs. Ford is reportedly preparing to open the program amid feedback from its dealers.

Ford poised to open dealers network to sell EVs

After asking dealers to pause EV investments this week, Ford is finalizing changes to the program. Ford already eased requirements last year due to “changes in the market.”

Ford spokesperson Marty Gunsberg confirmed that several dealers opted out of the program this past December. Gunsberg said, “Enrollments for 2024 are just over 50% of the network.” That’s down from about two-thirds confirmed by CEO Jim Farley a year prior.

According to Automotive News, after a series of meetings between dealers and executives, Ford is now preparing to allow all dealers to sell EVs.

Ford is expected to update the financial requirements needed to qualify. Previously, dealers were required to invest at least $500,000 to enroll in the program. For $1.2 million, dealers could be eligible for the “Elite” tier, which included additional chargers, demo units, and a presence on Ford.com.

If dealers didn’t want to invest, they couldn’t sell Ford EVs. Ford’s vice president of EV programs, Lisa Drake, said the company no longer believes having select dealers sell EVs is the right plan.

More dealers want in but with less financial commitment

“What we’re finding is more dealers want to be involved in it and we don’t want to be exclusive to just a handful,” Drake said. “And so we’re making a change where we’re opening up that and not requiring as many certifications or investments for a dealer to participate in the EV revolution.”

Meanwhile, the changes will not be finalized until early June, when Ford meets with its dealer council.

It’s unclear how much Ford will reduce financial requirements to sell EVs, but many believe it will be drastically relaxed to promote participation.

Drake said Ford will be “more ubiquitous with our training and make sure essentially all of our dealers are equipped to sell them” going forward. Ford will need to figure out how to deal with those who have already made investments at the upcoming dealer council meeting.

Ford slashed prices on its popular Mustang Mach-E and F-150 Lightning in recent months to boost sales.

After cutting Mach-E prices by up to $8,100 earlier this year, Ford introduced a new 0% APR offer on 2024 models this week.

2024 Mustang Mach-E trim Range Starting Price
Mustang Mach-E Select 250 mi $39,995
Mustang Mach-E Premium 320 mi $43,995
Mustang Mach-E GT 280 mi $53,995
Mustang Mach-E Rally 265 mi $59,995

Ford also introduced new discounts on the 2023 F-150 Lightning this week, offering up to $15,000 off MSRP. F-150 Lightning lease prices were cut by over $400 a month.
