The creators of the solar-powered locomotive of the future were aiming to set a Guinness record for speed last weekend, and that is more than just your ordinary attention-getting stunt. Demonstrating the functionality of PV panels on rail cars could help set the stage for solar power to knock diesel fuel out of the railroad business. No word yet on the official results, but solar is beginning to wiggle its way into a field dominated by fossil fuel.

The Solar Train Of The Future Hits The Tracks, With Only Solar Power

When people say “solar train,” they usually mean a battery-powered train charged by solar panels parked in a solar farm, such as the UK’s Riding Sunbeams project. In other words, the solar power is there, but it is not actually along for the ride.

Placing solar panels on the roof of the train itself is a whole ‘nother kettle of fish. A cute retro solar train began ferrying passengers on a six-kilometer round trip route in Byron, Australia back in 2017, but that’s the main extent of the activity so far, at least in terms of powering entire trains with sunlight.

It’s possible that the Byron train could go faster and farther with more solar panels, but integrating rooftop panels into the train’s 1940s-era styling was a key consideration that limits its ability to soak up energy from the sun.

The team behind the record-aspiring Solar Train are under no such constraints. Aesthetics have been tossed aside in favor of function, and solar panels are just about all there is to the Solar Train in its current 42-foot long iteration. Aside from a small space for the driver and a couple of passengers, all of the rail car’s flat surface is taken up by solar panels.

The goal for 2022 is to engineer an 80-foot version that can reach a top speed of 65 miles per hour on raw solar power alone.

As for that whether or not the Solar Train made the record books last weekend, check back with the The Press-Democrat of Sonoma County, California. They covered a test run of the Solar Train last Friday and their story is loaded with interesting details about the self-funded labor-of-love project, so maybe they’ll do a followup after the official results roll in.

Who Hearts Solar Power For The Locomotive Of The Future?

The Solar Train began as a DIY project in 2016, and now some heavy hitters in the US railway business are eyeballing the action.

Solar Train’s website lists Northwestern Pacific and Sierra Railroad as supporters, along with American Systems Controls & Integration, Inc., Cal Poly, and something called robotcity.io.

Northwestern Pacific has undergone something of a transformation from its roots in the great age of the steam locomotion, back in 1869. The whole industry shifted into diesel by the 1930s, and in 2006 NWP embarked on a major renovation and expansion project in its California territory. The company began its modern era of service in 2011, right about the time when President Obama’s plans for climate action began to kick into gear.

The Obama Clean Power Plan got hung up in court, but meanwhile NWP kept expanding its network into Marin and Sonoma counties. While still relying on diesel, NWP touts the advantages of railways for freight transportation over diesel trucks.

“Railroads are a very efficient mode of transportation; steel wheels on steel rail give very little rolling resistance, therefor reducing overall fuel consumption, pollution, and greenhouse gasses. NWP takes this one step further by using low emission Tier 3 locomotives for goods movements along the hwy 101 corridor. Each railcar that NWP hauls can handle up to 220,000 pounds of payload, that’s more than 8 trucks off the busy highways and roads per railcar for each round trip!” NWP enthuses.

Interesting! They left out that bit about the labor advantage of railways over trucks. If and when the trucking industry shifts into battery electric and fuel cell technology, each truck is still going to need at least one driver, and the the truck driver shortage shows little sign of easing. Meanwhile, it’s a piece of cake for one engineer to manage a 100-car freight train, though rail safety regulators may have something to say about that.

Sierra Railroad & The Electric Train Of The Future

As of this writing NWP has not built much of a public profile in the clean power area, though positive press related to the Solar Train could convince the company to throw some clams into the innovation pot. NWP’s Sonoma County rail network has been hosting the train’s trial runs, and the activity will continue at least into 2022, when the Solar Train team will try for the 65 mph goal.

Sierra Railroad has staked out a somewhat more ambitious position. Last year the company nailed down a $4 million grant to build a “green” switcher locomotive powered by zero emission hydrogen fuel cells. That’s actually not very green at all, considering that the primary source of the global hydrogen supply is natural gas. This year, the California utility SoCalGas also hopped on board the project, which doesn’t exactly inspire confidence in a green makeover.

On the bright side, interest in the green hydrogen field is blowing up like a rocket to Mars. SoCalGas is among those dipping a toe in the power-to-gas field, which refers to systems that apply clean kilowatts from solar power, wind power, and other renewables to water, in order to release renewable hydrogen gas.

Here in the US, signs of a green makeover for the hydrogen economy are already brewing, and the activity is especially strong in sunny California and the sunny southwest, which could mean good things for solar developers.

In a couple of especially interesting developments in the western US, Texas is eyeballing a green hydrogen hub that leverages its considerable solar and wind assets, and Utah is helping to propel the natural gas-to-green-hydrogen turbine trend along with the hydrogen-as-storage model.

Onward & Upward For The Solar Powered Railway Of The Future

Meanwhile, solar power is already beginning to establish workhorse status in the railroad industry. One interesting example comes from the firm Herzog, which is pitching a solar-powered system for remotely unloading ballast cars, which are freight cars that can be unloaded by opening a vent at the bottom.

“During ballast distribution, our remotely operated hydraulically-powered doors provide easy opening and closing. The doors eliminate the need for manual manipulation/operation, and only a single operator is required for ballast distribution, increasing efficiency and safety for your employees,” Herzog explains.

The company Trina Solar also takes note that India has been deploying solar panels on trains to power fans and other equipment. While not replacing diesel entirely, the addition of solar power can make a significant difference.

“In India, the addition of solar PV panels to just one train is estimated to save 5,547 gallons of diesel every year, a savings equivalent to nearly $20,000. These panels do not yet propel the locomotive but merely power its fans, lights and comfort systems, underscoring the enormous opportunity to further curb operating expenses by switching to renewables,” says Trina.

Electrified railways have already made diesel fuel obsolete for many commuter lines, but there are still plenty of other opportunities for solar power to wiggle its way into the railways of the world.

This new wireless e-bike charger wants to be the future of electric bikes

This new wireless e-bike charger wants to be the future of electric bikes

Forget fumbling with cables or hunting for batteries – TILER is making electric bike charging as seamless as parking your ride. The Dutch startup recently introduced its much-anticipated TILER Compact system, a plug-and-play wireless charger engineered to transform the user experience for e-bike riders.

At the heart of the new system is a clever combo: a charging kickstand that mounts directly to almost any e‑bike, and a thin charging mat that you simply park over. Once you drop the kickstand and it lands on the mat, the bike begins charging automatically via inductive transfer – no cable required. According to TILER, a 500 Wh battery will fully charge in about 3.5 hours, delivering comparable performance to traditional wired chargers.

It’s an elegantly simple concept (albeit a bit chunky) with a convenient upside: less clutter, fewer broken cables, and no more need to bend over while feeling around for a dark little hole.

TILER claims its system works with about 75% of existing e‑bike platforms, including those from Bosch, Yamaha, Bafang, and other big bames. The kit uses a modest 150 W wireless power output, which means charging speeds remain practical while keeping the system lightweight (the tile weighs just 2 kg, and it’s also stationary).

TILER has already deployed over 200 charging points across Western Europe, primarily serving bike-share, delivery, hospitality, and hotel fleets. A recent case study in Munich showed how a cargo-bike operator saved approximately €1,250 per month in labor costs, avoided thousands in spare batteries, and cut battery damage by 20%. The takeaway? Less maintenance, more uptime.

Now shifting to prosumer markets, TILER says the Compact system will hit pre-orders soon, with a €250 price tag (roughly US $290) for the kickstand plus tile bundle. To get in line, a €29 refundable deposit is currently required, though they say it is refundable at any point until you receive your charger. Don’t get too excited just yet though, there’s a bit of a wait. Deliveries are expected in summer 2026, and for now are covering mostly European markets.

The concept isn’t entirely new. We’ve seen the idea pop up before, including in a patent from BMW for charging electric motorcycles. And the efficacy is there. Skeptics may wonder if wireless charging is slower or less efficient, but TILER says no. Its system retains over 85% efficiency, nearly matching wired charging speeds, and even pauses at 80% to protect battery health, then resumes as needed. The tile is even IP67-rated, safe for outdoor use, and about as bulky as a thick magazine.

Electrek’s Take

I love the concept. It makes perfect sense for shared e-bikes, especially since they’re often returning to a dock anyway. As long as people can be trained to park with the kickstand on the tile, it seems like a no-brainer.

And to be honest, I even like the idea for consumers. I know it sounds like a first-world problem, but bending over to plug something in at floor height is pretty annoying, not to mention a great way to throw out your back if you’re not exactly a spring chicken anymore. Having your e-bike start charging simply by parking it in the right place is a really cool feature! I don’t know if it’s $300 cool, but it’s pretty cool!

Tesla launches new software update with Grok, but it doesnt even interface with the car

Tesla launches new software update with Grok, but it doesnt even interface with the car

Tesla has launched a new software update for its vehicles that includes the anticipated integration of Grok, but it doesnt even interface with the car yet.

Earlier this week, CEO Elon Musk said that Tesla would integrate Grok, the large language model developed by his private company, xAI, into its vehicles.

Today, Tesla started pushing the update to the fleet, but there’s a significant caveat.

The automaker wrote in the release notes (2025.26):

Grok (Beta) (US, AMD)

Grok now available directly in your Tesla

Requires Premium Connectivity or a WiFi connection

Grok is currently in Beta & does not issue commands to your car – existing voice commands remain unchanged.

First off, it is only available in vehicles in the US equipped with the AMD infotainment computer, which means cars produced since mid-2021.

But more importantly, Tesla says that it doesn’t send commands to the car under the current version. Therefore, it is simply like having Grok on your phone, but on the onboard computer instead.

Tesla showed an example:

There are a few other features in the 2025.26 software update, but they are not major.

For Tesla vehicles equipped with ambient lighting strips inside the car, the light strip can now sync to music:

Accent lights now respond to music & you can also choose to match the lights to the album’s color for a more immersive effect

Toybox > Light Sync

Here’s the new setting:

The audio setting can now be saved under multiple presets to match listening preferences for different people or circumstances:

The software update also includes the capacity to zoom or adjust the playback speed of the Dashcam Viewer.

Cybertruck also gets the updated Dashcam Viewer app with a grid view for easier access and review of recordings:

Tesla also updated the charging info in its navigation system to be able to search which locations require valet service or pay-to-park access.

Upon arrival, drivers will receive a notification with access codes, parking restrictions, level or floor information, and restroom availability:

Finally, there’s a new onboarding guide directly on the center display to help people who are experiencing a Tesla vehicle for the first time.

Electrek’s Take

Tesla is really playing catch-up here. Right now, this update is essentially nothing. If you already have Grok, it’s no more different than having it on your phone or through the vehicle’s browser, since it has no capacity to interact with any function inside the vehicle.

Most other automakers are integrating LLMs inside vehicles with the capacity to interact with the vehicle. In China, this is becoming standard even in entry-level cars.

In the Xiaomi YU7, the vehicle’s AI can not only interact with the car, but it also sees what the car sees through its camera, and it can tell you about what it sees:

Tesla is clearly far behind on that front as many automakers are integrating with other LLMs like ChatGPT and in-house LLMs, like Xiaomi’s.

Robinhood is up 160% this year, but several obstacles are ahead

Robinhood is up 160% this year, but several obstacles are ahead

Florida AG opens probe into Robinhood. Here's the latest

Robinhood stock hit an all-time high Friday as the financial services platform continued to rip higher this year, along with bitcoin and other crypto stocks.

Robinhood, up more than 160% in 2025, hit an intraday high above $101 before pulling back and closing slightly lower.

The reversal came after a Bloomberg report that JPMorgan plans to start charging fintechs for access to customer bank data, a move that could raise costs across the industry.

For fintech firms that rely on thin margins to offer free or low-cost services to customers, even slight disruptions to their cost structure can have major ripple effects. PayPal and Affirm both ended the day nearly 6% lower following the report.

Despite its stellar year, the online broker is facing several headwinds, with a regulatory probe in Florida, pushback over new staking fees and growing friction with one of the world’s most high-profile artificial intelligence companies.

Florida Attorney General James Uthmeier opened a formal investigation into Robinhood Crypto on Thursday, alleging the platform misled users by claiming to offer the lowest-cost crypto trading.

“Robinhood has long claimed to be the best bargain, but we believe those representations were deceptive,” Uthmeier said in a statement.

The probe centers on Robinhood’s use of payment for order flow — a common practice where market makers pay to execute trades — which the AG said can result in worse pricing for customers.

Robinhood Crypto General Counsel Lucas Moskowitz told CNBC its disclosures are “best-in-class” and that it delivers the lowest average cost.

“We disclose pricing information to customers during the lifecycle of a trade that clearly outlines the spread or the fees associated with the transaction, and the revenue Robinhood receives,” added Moskowitz.

Robinhood CEO Vlad Tenev explains 'dual purpose' behind trading platform's new crypto offerings

Robinhood is also facing opposition to a new 25% cut of staking rewards for U.S. users, set to begin October 1. In Europe, the platform will take a smaller 15% cut.

Staking allows crypto holders to earn yield by locking up their tokens to help secure blockchain networks like ethereum, but platforms often take a percentage of those rewards as commission.

Robinhood’s 25% cut puts it in line with Coinbase, which charges between 25.25% and 35% depending on the token. The cut is notably higher than Gemini’s flat 15% fee.

It marks a shift for the company, which had previously steered clear of staking amid regulatory uncertainty.

Under President Joe Biden‘s administration, the Securities and Exchange Commission cracked down on U.S. platforms offering staking services, arguing they constituted unregistered securities.

With President Donald Trump in the White House, the agency has reversed course on several crypto enforcement actions, dropping cases against major players like Coinbase and Binance and signaling a more permissive stance.

Even as enforcement actions ease, Robinhood is under fresh scrutiny for its tokenized stock push, which is a growing part of its international strategy.

The company now offers blockchain-based assets in Europe that give users synthetic exposure to private firms like OpenAI and SpaceX through special purpose vehicles, or SPVs.

An SPV is a separate entity that acquires shares in a company. Users then buy tokens of the SPV and don’t have shareholder privileges or voting rights directly in the company.

OpenAI has publicly objected, warning the tokens do not represent real equity and were issued without its approval. In an interview with CNBC International, CEO Vlad Tenev acknowledged the tokens aren’t technically equity shares, but said that misses the broader point.

JPMorgan announces plans to charge for access to customer bank data

“What’s important is that retail customers have an opportunity to get exposure to this asset,” he said, pointing to the disruptive nature of AI and the historically limited access to pre-IPO companies.

“It is true that these are not technically equity,” Tenev added, noting that institutional investors often gain similar exposure through structured financial instruments.

The Bank of Lithuania — Robinhood’s lead regulator in the EU — told CNBC on Monday that it is “awaiting clarifications” following OpenAI’s statement.

“Only after receiving and evaluating this information will we be able to assess the legality and compliance of these specific instruments,” a spokesperson said, adding that information for investors must be “clear, fair, and non-misleading.”

Tenev responded that Robinhood is “happy to continue to answer questions from our regulators,” and said the company built its tokenized stock program to withstand scrutiny.

“Since this is a new thing, regulators are going to want to look at it,” he said. “And we expect to be scrutinized as a large, innovative player in this space.”

SEC Chair Paul Atkins recently called the model “an innovation” on CNBC’s Squawk Box, offering some validation as Robinhood leans further into its synthetic equity strategy — even as legal clarity remains in flux across jurisdictions.

Despite the regulatory noise, many investors remain focused on Robinhood’s upside, and particularly the political tailwinds.

The company is positioning itself as a key beneficiary of Trump’s newly signed megabill, which includes $1,000 government-seeded investment accounts for newborns. Robinhood said it’s already prototyping an app for the ‘Trump Accounts‘ initiative.
