Two Japanese firms have entered into a joint development agreement with Ireland-headquartered DP Energy to work on the initial phase of a tidal energy project in Canada.

In statements released earlier this week Chubu Electric Power and Kawasaki Kisen Kaisha, or “K” Line, said the agreement related to the Uisce Tapa Tidal Energy project. The development is located at the Fundy Ocean Research Centre for Energy in the Bay of Fundy, an inlet between the Canadian provinces of New Brunswick and Nova Scotia. 

Both Chubu Electric Power and “K” Line described it as “the first tidal energy project in which a Japanese company will participate overseas.”

According to DP Energy, the first phase of Uisce Tapa — Irish for “fast water” — is centered around three 1.5 megawatt turbines. The second aims to increase the project’s capacity to 9 MW.

Uisce Tapa is backed by a 15-year power purchase agreement with Nova Scotia Power Incorporated, which comes in at $530 Canadian dollars (around $422) per megawatt hour. It’s also benefited from a grant of around $30 million Canadian dollars from Natural Resources Canada.

In its announcement Wednesday, DP Energy described the Bay of Fundy as “being home to some of the highest tides in the world.” At peak surface speed, tidal currents there are “capable of exceeding 10 knots” or 5 meters per second, it added.

The project is being considered for approval by Fisheries and Oceans Canada, according to Chubu Electric Power and “K” Line. If all goes to plan, the first turbine would start operations in 2023, followed by two others in 2026.

The news comes in the same week that tidal energy business Nova Innovation said it was able to move forward with a project focused on scaling up the production of tidal turbines after receiving funding from the Scottish government.

The £2 million ($2.77 million) funding boost, announced Thursday, will be used to support the company’s Volume Manufacturing and Logistics for Tidal Energy project, also known as VOLT.

VOLT will “develop the first European assembly line to mass manufacture tidal turbines,” according to Nova, and also “trial innovative techniques and tools to ship, deploy and monitor turbines around the world.”

Last week another company, Orbital Marine Power, said its O2 turbine had started grid-connected power generation at the European Marine Energy Centre in Orkney, an archipelago north of the Scottish mainland.

The 2-megawatt O2 has been dubbed “the world’s most powerful tidal turbine,” weighs 680 metric tons and is 74 meters long.

Alibaba delivers again with this crazy octuple (8x) suspension e-bike for $350

Alibaba delivers again with this crazy octuple (8x) suspension e-bike for 0

I’m going to start this off by immediately begging you not to buy this ridiculous contraption you’ll see in the article below. You’ve been warned. Ok, now feast your eyes on this monstrosity! A $350 e-bike from Alibaba that comes with not just a suspension fork, not just full-suspension, but at least five more shocks than any bike should ever conceivably possess, seemingly randomly sprinkled around the bike’s frame.

Credit goes to my publisher, Seth, for finding this absolute gem. He and I play a little game where we send each other increasingly ridiculous Alibaba finds, trying to one-up the insanity of the other’s previous find. This one is definitely a contender.

Spotted on AliExpress’s platform, the site that makes it dangerously easy to procure the strangest (and sometimes coolest) things from the Far East, this is an e-bike that just keeps on giving.

First of all, check out the suspension. There’s a front suspension fork, which is theoretically standard. There’s also rear suspension, but instead of the single rear shock or occasional dual shocks (one on either side), the designers of this e-bike gave us quad shocks. Then, instead of leaving not-well-enough alone, they decided that a rear swingarm with quad shocks wasn’t enough, and then turned the entire rear half of the e-bike into another swingarm with two more shocks.

At this point, I’m starting to get confused. Do we call the battery sprung or unsprung weight now?

This much suspension is like trying to drink from a firehose, but we’re not even finished. Because if that wasn’t enough springiness for you, there are two more springs in the saddle, technically bringing us up to 10 springs total! A guy hit a speed bump on this e-bike last week, and some say he’s still bouncing.

While I’d like to give them the benefit of the doubt, my experience with the cheapest of Alibaba e-bikes tells me that they likely didn’t modify the spring rate of the shocks when they just kept copy/pasting them. That means the bike probably rides stiffer than if it had half the number of shocks (or it just has the proper pre-load for a 600 lb rider).

Unfortunately, the rest of the bike is rather par for the course in terms of cheap direct-from-China electric bicycles. We’ve got our “500 Watt” motor, a surprisingly large 48V 15Ah battery, folding handlebars, a cute little rear kid’s seat complete with grab bar (a nice touch, to be honest), a full twist throttle, fenders, and even a complete lighting package with turn signals.

The 66-lb (30 kg) bike isn’t very light, but each of those shocks adds to the poundage, not to mention all the other doodads we’ve got bolted on around the bike.

The bike still folds in half, which is surprising considering most of the frame is taken up by springs. At first glance, I didn’t even see the folding mechanism hiding there.

It’s a wild specimen, and the free shipping to the US makes the $350 price even more tempting. But please don’t buy something like this (that lead image is AI-generated… I didn’t buy or ride this!). There are some real concerns here. Who knows what kind of quality control or safety certification went into that battery, let alone the frame and other key components?

Let’s just enjoy this one on the screen like most of my Alibaba finds and appreciate that someone out there said, “let’s see how many cheap shocks we can fit on a bike,” and nobody stopped them.

Yes, an EV really CAN power your home – if it's one of these (*)

Can an EV really help power your home when the power goes out? It’s one of the biggest FAQs people have about electric cars — but the answer can be a bit confusing. It’s either a yes, with a but – or a no, with an unless. To find out which EVs can offer vehicle-to-home (V2H) tech to keep the lights on or even lower your energy bills, keep on reading.

Modern EVs have big, efficient batteries capable of storing enough energy to power home for days. That can mean backup power during a storm or the ability to use stored energy during expensive peak hours and recharge again when kilowatts are cheap.

That’s all true – but only in theory. Because, while your EV might have a big battery, that doesn’t mean it has the special hardware and software that allow electricity to safely flow back out of the car baked in. Car companies call this vehicle-to-home (V2H) or bi-directional charging, and only a handful of models currently support it. That’s that, “yes, with a but” asterisk.

Yes, an EV can power your home, but it has to be one of these.

Ford F-150 Lightning

Ford made early headlines using its F-150 Lightning as a life-saving generator during winter ice storms and hurricanes, so it should come as no surprise that it’s included in this list. The best-selling electric truck in America can send up to 9.6 kW of power from its onboard batteries back to the house. More than enough to keep the lights on and the refrigerator running during an outage.

To make it work, you’ll need to install the Charge Station Pro (formerly called Intelligent Backup Power) home charger, the Home Integration System (HIS), which includes an inverter, a transfer switch, and a small battery to switch the system on, as well Ford’s Charge Station Pro 80A bi-directional charger (which comes free with the Extended Range F-150 Lightning, but costs about $1,300 otherwise).

All-in, you’re looking at about $5,000 in hardware, plus installation, to make it work.

Kia EV9

With up to 300 miles of range and ultra-fast charging, the seven-passenger electric SUV from Kia has been a hot seller. And back in March, the Kia EV9 unlocked yet another new feature: vehicle-to-home charging.

When paired with the Quasar 2 bidirectional charger from Wallbox (and the associated Power Recovery Unit, or PRU), a fully-charged Kia EV9 can power a standard suburban home for three days. Longer, still, if you’re keeping the energy use low. The Wallbox Quasar 2 isn’t cheap, though – pricing starts at $6,440 (again, plus installation). For that price, you the PRU plus a wall-mounted 12 kW L2 charger with 12.8 kW of with discharge power on a split-phase system.

Pretty much all the GM EVs

With the exception of the Chevy Brightdrop, GMC Hummer EV, and the hand-built, ultra-luxe Cadillac CELESTIQ, every Ultium-based GM EV can send battery power back to your home through GM Energy’s Ultium Home System – arguably the most fully integrated EV + battery backup + solar option out there outside of Tesla.

GM Energy says its new 19.2 kW Powershift Charger delivers around 6-7% more juice than a typical 11.5 kW L2 charger, delivering up to 51 miles of range per charge hour. Bi-directional charging requires the Powershift Charger to be paired up with a compatible GM EV and the GM Energy V2H Enablement Kit. The full system retails for $12,699, plus installation, and can be financed through GM Financial.

NOTE: some 2024 models might require a software update to enable V2H functionality, which can be done either at the dealer or through an OTA update.

Tesla Cybertruck


Tesla Cybertruck stuck in mud.

Tesla Cybertruck owners may have zero taste, but they have two options when it comes to powering their homes with their trucks. If they already have a Tesla Powerwall, they don’t need anything else. If they don’t, they’ll need to install a Universal Wall Connector charger, a Powershare Gateway, and a Tesla Backup Switch.

That second option will run about $3,500, plus installation.

That rounds off the list of vehicles that ship with V2H software baked in, so if you’re wondering whether or not your EV can be used to power your home, now you know the answer is yes, as long as it’s one of the ones listed above.

But you might remember that I answered the initial question by saying it was either a yes, with a but – or a no, with an unless. So if you want to use your car’s battery as a backup, but don’t have one of the EVs liksted above, that doesn’t mean you’re completely out of luck.

No, with an unless


Fred Lambert explains Sigenergy V2X system.

As some of the earliest and most enthusiastic EV adopters, Tesla fans have also been among the loudest advocates for using the energy stored their cars’ batteries to back up their homes — or even the grid itself. Unfortunately for them, the slow-selling Cybertruck is the only Tesla vehicle that officially supports bi-directional charging. If you’re one of the many Model 3 and Y owners frustrated by those delays, there’s good news: those vehicles are now capable of V2H charging thanks to an “impressive” Powerwall competitor, Sigenergy.

The good news doesn’t stop there, however. The Sigenergy V2X also works with both the popular Kia EV6 and Electrek‘s 2024 EV of the Year, the Volvo EX30 over the DIN70121 protocol, and several VW/Audi/Porsche and Mercedes-Benz EVs over the ISO15118-2 protocol.

Our own Editor-in-Chief, Fred Lambert, recently went on a Sigenergy deep dive with Sylvain Juteau, President of Roulez Electrique, and came away deeply impressed with the system. I’ve included the video, above, and you can read more about the system itself at this link.

And, of course, I look forward to learning about any V2H models or more universal battery backup systems from you, the smartest readers in the blogosphere, in the comments.

Tesla changes meaning of ‘Full Self-Driving’, gives up on promise of autonomy

Tesla changes meaning of 'Full Self-Driving', gives up on promise of autonomy

Tesla has changed the meaning of “Full Self-Driving”, also known as “FSD”, to give up on its original promise of delivering unsupervised autonomy.

Since 2016, Tesla has claimed that all its vehicles in production would be capable of achieving unsupervised self-driving capability.

CEO Elon Musk has claimed that it would happen by the end of every year since 2018.

Tesla has even sold a software package, known as “Full Self-Driving Capability” (FSD), for up to $15,000 to customers, promising that the advanced driver-assist system would become fully autonomous through over-the-air software updates.

Almost a decade later, the promise has yet to be fulfilled, and Tesla has already confirmed that all vehicles produced between 2016 and 2023 don’t have the proper hardware to deliver unsupervised self-driving as promised.

Musk has been discussing the upgrade of the computers in these vehicles to appease owners, but there’s no concrete plan to implement it.

While there’s no doubt that Tesla has promised unsupervised self-driving capabilities to FSD buyers between 2016 and 2023, the automaker has since updated its language and now only sells “Full Self-Driving (Supervised)” to customers:

The fine print mentions that it doesn’t make the vehicle “autonomous” and doesn’t promise it as a feature.

In other words, people buying FSD today are not really buying the capability of unsupervised self-driving as prior buyers did.

Furthermore, Tesla’s board has just submitted a new, unprecedented CEO compensation package for shareholders’ approval, which could give Musk up to $1 trillion in stock options pending the achievement of certain milestones.

One of these milestones is Tesla having “10 Million Active FSD Subscriptions.”

At first glance, this would be hopeful for FSD buyers since part of Musk’s compensation would be dependent on delivering on the FSD promises.

However, Tesla has changed the definition of FSD in the compensation package with an extremely vague one”

“FSD” means an advanced driving system, regardless of the marketing name used, that is capable of performing transportation tasks that provide autonomous or similar functionality under specified driving conditions.

Tesla now considers FSD only an “advanced driving system” that should be “capable of performing transportation tasks that prove autonomous or similar functionality”.

The current version of FSD, which requires constant supervising by the driver, could easily fit that description.

Therefore, FSD now doesn’t come with the inital promise of Tesla owners being able to go to sleep in their vehicles and wake up at their destination – a promise that Musk has used to sell Tesla vehicles for years.

Electrek’s Take

The way Tesla discusses autonomy with customers and investors versus how it presents it in its court filings and legally binding documents is strikingly different.

It should be worrying to anyone with an interest in this.

With this very vague description in the new CEO compensation package, Tesla could literally lower the price of FSD and even remove base Autopilot to push customers toward FSD and give Musk hundreds of billions of dollars in shares in the process.

There’s precedent for Tesla decreasing pricing on FSD. Initially, Musk said that Tesla would gradually increase the price of the FSD package as the features improved and approached unsupervised autonomy.

That was true for a while, but then Tesla started slashing FSD prices, which are now down $7,000 from their high in 2023:

The trend is quite apparent and coincidentally began when Tesla’s sales started to decline.

FSD is now a simple ADAS system without any promise of unsupervised self-driving. This might quite honestly be one of the biggest cases of false advertising or bait-and-switch ever.
