Mike Roeth has clocked thousands of miles pulling his solar-powered recreational vehicle around the country in his quest to make trucking cleaner and more efficient. For some it may seem strange that an effort to curb fuel takes fuel, since Roeth pulls his RV with a diesel-powered Ford F-250.

But for Roeth, executive director of the North American Council for Freight Efficiency (NACFE) and trucking lead for RMI, it makes total sense. Roeth likes to live by the concept of “gemba,” a Japanese word meaning “the actual place.” He learned it in the 1990s while he was managing a plant for a manufacturer of engines and power systems. His plant was implementing a production system similar to Toyota’s, and Roeth was studying the Japanese automaker’s efforts when he discovered gemba.

Gemba means going to see the actual process and learning from those who do the work. Inside a Toyota factory, it means that management walks the floor to observe the manufacturing process up close. In Roeth’s world, it means that he is constantly out on the road, meeting with trucking companies and chatting with truck drivers. His goal is to understand the latest technologies for reducing emissions in a sector that is responsible for 24 percent of transportation’s greenhouse gas footprint.

Roeth grew up on a farm near Dayton, Ohio. He has been around tractors and trucks since he was a toddler. After graduating from Ohio State University with an engineering degree and working with different companies, he eventually became a vice president at Navistar, the company that owns the International brand of trucks and diesel engines. Roeth traveled a lot for work, and when he left Navistar, he decided he wanted to spend more time with his wife, Letty. He told her he would look for a job in Fort Wayne, Indiana, where they were living at the time.

Letty, however, knew her husband better than that. “That’s not you—you have to be traveling and out with people,” she told him. “Why don’t we buy a camper? I’ll go with you and see how we like it.” Roeth became an industry consultant, and they instantly fell in love with working on the road.

Getting the Efficiency Bug

Although Roeth loves working in the trucking industry, he was bothered by the lack of interest in efficiency technologies when fuel prices were low. “I was frustrated to find out that over the past 50 years, when fuel prices went up the industry wanted to lower costs and be more efficient, but when prices went down they didn’t,” he said. As a result, a lot of efficiency technologies were being discarded. “I knew that we need to and can do better with the emissions that move our goods.”

Around the same time that the Roeths were taking to the road, RMI hosted a workshop on efficient trucking with the goal of doubling the efficiency of the trucking sector. NACFE, an independent organization helping to drive efficiency in the trucking sector, was born out of that charrette, and Roeth was the perfect person to take it on.

“The thing I like about trucking is that it’s a small industry: only about half a million trucks are produced in a given year. It forces everyone to work together,” Roeth says. “Even though all the companies have divergent goals, and there’s a very diverse, complex market of trucking, it’s also incredibly collaborative.” That dynamic is ideal for Roeth, who excels at getting people together to work toward a common goal.

“Mike has an incredible resume of experience,” says Amanda Phillips, general manager of OEM (original equipment manufacturer) sales at Meritor, a corporation that makes truck components. “He is always willing to share ideas and teach others. His energy and positive attitude are contagious.” From 2010 to 2016, Roeth nurtured NACFE from a small startup nonprofit to the leading organization on trucking efficiency. According to Phillips, “Mike’s entrepreneurial spirit and his work with NACFE have helped fleets better understand available technologies and the impact those advances can make in their fleet’s carbon footprint.”

During that same time, the Roeths got progressively bigger campers and started being gone more often. They eventually sold their house, got rid of most of their stuff, and became full-time RVers. They now have a 41-foot Jayco Eagle outfitted with a 1.4 kilowatt solar array to run their appliances.

The Roeths’ next step is to replace both their truck and camper with a motor home that pulls an electric car. Then, when parked at a campsite, they can drive their electric car for shorter trips. They hope to eventually get away from fossil fuels completely with an electric or hydrogen-powered truck that can pull an RV.

The Birth of Run on Less

In 2016, the NACFE team was trying to figure out how efficient a tractor trailer could be if it incorporated the best available efficiency technologies. The team thought the best way to do that was to track some of the most fuel-efficient trucks, driven by efficiency-focused drivers. And with that, Run on Less was born.

The first Run on Less event featured seven fleets, outfitted with different fuel-efficiency measures, in a cross-country demonstration. NACFE followed the fleets across the country and proved that fleets can improve their fuel efficiency by 25 percent if they adopt the right technologies.

The event was so successful that NACFE held a second Run on Less event in 2019. This one included 10 fleets, many very large, focused on regional haul. The second demonstration proved that the 800,000 trucks in North America could decrease their annual consumption of diesel from 8 billion gallons to 5.5 billion gallons, and eventually down to 1 billion gallons.

“Run on Less is just a gift that keeps on giving,” says Roeth. “It’s real, it’s human. We talk to truckers and the people buying trucks and running them, and then we share their stories and data. Do we like it because it’s fun or because the marketplace likes it? I think it’s a bit of both.”

To Roeth, the future of trucking looks bright. He’s most excited about electric and hydrogen trucks. “To think we can move freight with no emissions is incredible,” he says. “Trucking has done a lot. Diesel exhaust is cleaner now. I’m really proud of the industry. But it’s still carbon-based. I’m most excited about moving the industry to zero carbon.”

Roeth is getting an up-close glimpse at a carbon-free future for trucking in the third Run on Less demonstration, called Run on Less–Electric. This event, beginning September 2, features 13 electric trucks in a variety of real-world applications for companies including Frito-Lay, Anheuser-Busch, and Penske.

In addition to new technologies, Roeth is also excited about the changes in terms of diversity that he has seen over the 35 years he’s been involved in the industry. “The meetings I was in 30 years ago were all mostly white men. Now we have women and people of color involved from management to drivers,” he explains.

Living the Gemba Way

While many people took to the road during the COVID pandemic, the Roeths actually stayed put. Part of the joy of being on the road for the Roeths is not only attending industry events, but also going to museums, sporting events, and pubs, and meeting interesting people across the country.

Mike Roeth: Decarbonizing Trucking from the RoadWith COVID putting a stop to most of that, they felt they had no reason to go anywhere, so they hunkered down in Indiana. But it wasn’t the same. “During the pandemic I felt I was getting out of touch with trucking,” says Roeth. So he is now back on the road meeting with trucking companies, manufacturers, and drivers.

In the weeks leading up to Run on Less–Electric, he has been traveling around the country visiting most of the 13 companies involved, from Los Angeles to New York City. He has conducted dozens of interviews of fleet managers, company leaders, and truck drivers.

In this way, he learns firsthand about the benefits of electric trucks as well as any challenges the companies have faced. He then uses this knowledge to help increase the use of electric trucks in the industry. After one and a half years of COVID, he is back in his element: observing, listening, learning, and sharing ideas face-to-face. And that’s at the heart of how Roeth tries to live—the gemba way.

Tesla prototype sparks speculation: a Model Y, maybe slightly smaller

Tesla prototype sparks speculation: a Model Y, maybe slightly smaller

A new Tesla prototype was spotted again, reigniting speculation among Tesla shareholders, even though it’s likely just a Model Y, potentially a bit smaller, and the upcoming stripped-down, cheaper version.

Over the last few months, there have been several sightings of what appears to be a Model Y with camouflage around Tesla’s Fremont factory.

It sparked a lot of speculation about it being the new “affordable” compact Tesla vehicle.

There’s confusion in the Tesla community around Tesla’s upcoming “affordable” vehicles because CEO Elon Musk falsely denied a report last year about Tesla’s “$25,000” EV model being canceled.

Advertisement – scroll for more content

The facts are that Musk canceled two cheaper vehicles that Tesla was working on, commonly referred as “the $25,000 Tesla” in early 2024. Those vehicles were codenamed NV91 and NV92, and they were based on the new vehicle platform that Tesla is now reserving for the Cybercab.

Instead, Musk noticed that Tesla’s Model 3 and Model Y production lines were starting to be underutilized as the Company faced demand issues. Therefore, Tesla canceled the vehicles program based on the new platform and decided to build new vehicles on Model 3/Y platform using the same production lines.

We previously reported that these electric vehicles will likely look very similar to Model 3 and Model Y.

In recent months, several other media reports reinforced this, and Tesla all but confirmed it during its latest earnings call, when it stated that it is “limited in how different vehicles can be when built on the same production lines.”

Now, the same Tesla prototype has been spotted over the last few days, and it sent the Tesla shareholders community into a frenzy of speculations:

Electrek’s Take

As we have repeatedly reported over the last year, the new “affordable” Tesla “models” coming are basically only stripped-down Model 3 and Model Y vehicles.

They might end up being a little smaller by a few inches, and Tesla may use different model names, but they will be extremely similar.

If this is it, which is possible, you can see it looks almost exactly like a Model Y.

It’s hard to confirm if it’s indeed smaller because of the angle of the vehicle compared to the other Model Ys, but it’s not impossible that the wheelbase is a bit smaller – although it’s hard to confirm.

Either way, the most significant changes for these stripped-down, more affordable “models” are expected to be cheaper interior materials, like textile seats instead of vegan leather, no heated or ventilated seats standard, no rear screen, maybe even no double-panned acoustic glass and a lesser audio system.

As previously stated, the real goal of these new variants, or models, is to lower the average sale price in order to combat decreasing demand and maintain or increase the utilization rate of Tesla’s current production lines, which have been throttled down in the last few years to now about 60% utilization.

If this trend continues, Tesla would find itself in trouble and may even have to close its factories.

Ethereum is powering Wall Street’s future. The crypto scene at Cannes shows how far it’s come

Ethereum is powering Wall Street's future. The crypto scene at Cannes shows how far it's come

Ethereum succeeded beyond anyone's expectations, says network co-founder Vitalik Buterin at EthCC

CANNES — Wall Street’s new plumbing is being built on Ethereum and this week its architects took over the same French Riviera villas and red carpet venues that host the Cannes Film Festival in May.

The Ethereum Community Conference, or EthCC, took over the beachside town that was swarming with crypto founders, developers, and some of the institutional giants now building atop the infrastructure.

The crypto elite climbed the iconic red-carpeted steps of the Palais des Festivals — a cinematic landmark now repurposed as the stage for Ethereum’s flagship European event.

“The atmosphere this year was palpable in Cannes,” said Bettina Boon Falleur, the powerhouse behind EthCC for the past seven years. “The prestige of the location, combined with the quality of talks, has reinforced Ethereum’s stature and purpose in the wider ecosystem.”

Private parties sprawled across cliffside estates and exclusive resorts, but the conversations were less about price action and more about the blockchain’s evolving role as the back-end of global finance.

EthCC, now in its eighth year, has tracked Ethereum’s trajectory from scrappy experiment to institutional backbone.

“That impact was unmistakable this year,” Falleur said. “From Robinhood embracing decentralized finance infrastructure via Arbitrum to local governments like the City of Cannes exploring deeper integration with the crypto economy.”

Indeed, one of the boldest moves came this week from Robinhood, which became the first publicly traded U.S. company to launch tokenized stocks on-chain.

At a product showcase held inside a Belle Époque mansion overlooking the sea, Robinhood unveiled a sweeping new crypto strategy — including the ability for European users to trade tokenized U.S. stocks and ETFs via Arbitrum, a Layer 2 network built on Ethereum.

The announcement helped push Robinhood stock past $100 for the first time, capping off a week of fresh all-time highs and a more than 30% rally since being snubbed by the S&P 500 during a recent rebalance.

Inside the Palais des Festivals, ETHCC draws founders, developers, and institutions into the same halls that host the world’s biggest film premieres — this time, for the future of finance.

Ether, the token native to the Ethereum blockchain, was up nearly 6% on the week and several public equities tied to the blockchain have rallied alongside it.

BitMine Immersion Technologies, a company that mines bitcoin, gained more than 1,200% since announcing it would make ether its primary treasury reserve asset. Bit Digital, which recently exited bitcoin mining to “become a pure play” ethereum staking and treasury company, gained more than 34% this week. And SharpLink Gaming, which added more than $20 million in ether to its balance sheet this week, jumped more than 28% on Thursday.

Ether ETF inflows are rising again too — a sign that institutional investors are warming back up.

Ether is still down more than 20% this year and lags far behind bitcoin in market cap and adoption. But funds tracking ETH have seen two straight months of mostly net inflows, according to CoinGlass data. Still, ether ETFs total just $11 billion — compared to $138 billion in bitcoin ETFs.

Institutions aren’t betting on Ethereum for hype — they’re betting on infrastructure.

Even as prices stall and the network faces headwinds from slower base layer revenues and faster rivals like Solana, the momentum is shifting toward utility.

“Ethereum is getting plugged into these core transactional systems,” Paul Brody, global blockchain leader at EY, told CNBC on the sidelines of EthCC. “Investors, savers, people moving money — they are going to start shifting from some of the older mechanisms of doing this into Ethereum ecosystems that can do these transactions faster, cheaper, but also very importantly, with significant new functionality attached to it.”

Crypto founders and developers climb the iconic red-carpeted steps of the Palais des Festivals — a familiar backdrop for the Cannes Film Festival, now repurposed for Ethereum’s flagship European event.

Deutsche Bank recently announced it’s building a tokenization platform on zkSync — a faster, cheaper blockchain built on top of Ethereum — to help asset managers issue and manage tokenized funds, stablecoins, and other real-world assets while meeting regulatory and data protection requirements.

Coinbase and Kraken are also racing to own the crossover between traditional stocks and crypto.

Coinbase has filed with the SEC to offer trading in tokenized public equities, a move that would diversify its revenue stream and bring it into more direct competition with brokerages like Robinhood and eToro.

Kraken announced plans to offer 24/7 trading of U.S. stock tokens in select overseas markets.

BlackRock‘s tokenized money market fund, BUIDL — launched on Ethereum last year — offers qualified investors on-chain access to yield with redemptions settled in USDC in real time.

Stablecoins, meanwhile, continue to serve as the backbone of Ethereum’s financial layer.

Circle’s USDC — the second-largest stablecoin — still settles around 65% of its volume on Ethereum’s rails. According to CoinGecko’s latest “State of Stablecoins” report, Ethereum accounts for nearly 50% of stablecoin market share.

“The builders and contributors at EthCC aren’t chasing the next bull run,” Falleur said, “they’re laying the groundwork to make Ethereum home for the next billion users.”

Even as newer blockchains tout faster speeds and lower fees, Ethereum is proving its staying power as a trusted network.

Vitalik Buterin, Ethereum’s co-founder, told CNBC in Cannes that there is an assumption that institutions only care about scale and speed — but in practice, it’s the opposite.

Ethereum co-founder Vitalik Buterin delivers a keynote at ETHCC, laying out the network’s next steps — and its values test — as institutional adoption accelerates.

EthCC

“A lot of institutions basically tell us to our faces that they value Ethereum because it’s stable and dependable, because it doesn’t go down,” he said.

Buterin added that firms often ask about privacy and other long-term features — the kinds of concerns that institutions, he said, “really value.”

Tomasz Stańczak, the new co-executive director of the Ethereum Foundation, said institutions are choosing Ethereum for the same core reasons.

“Ten years without stopping for a moment. Ten years of upgrades, with a huge dedication to security and censorship resistance,” he said.

He added that when institutions send orders to the market, they want to be “absolutely sure that their order is treated fairly, that nobody has preference, that the transaction actually is executed at the time when it’s delivered.”

Those guarantees have become increasingly valuable as stablecoins and tokenized assets move into the mainstream.

The Senate’s recent passage of the GENIUS Act, along with Circle’s IPO, gave the industry a regulatory tailwind and helped reinforce Ethereum’s role as the infrastructure layer for tokenized finance.

Ethereum’s core values — neutrality, security, and censorship resistance — are emerging as competitive advantages.

The real test now is whether Ethereum can scale without losing its values.

“We don’t just want to succeed,” Buterin said from the mainstage of the Palais this week. “We want to be something that is worthy of succeeding.”

He said the hope is that future generations will look back and see a network that truly delivered openness, freedom, and permissionless access to the masses.

White-clad guests dance poolside at the rAAVE party in Cannes.

But the week didn’t end in the conference halls, it closed with tradition. On the balcony of Villa Montana, overlooking the Bay of Cannes, the rAAVE party lit up.

White-clad guests sipped cocktails as the DJ spun by the pool, haze curling from smoke machines.

This year, Chainlink co-founder Sergey Nazarov and DeFi icon Stani Kulechov, founder of Aave, stood atop the balcony overlooking the crowd and the light-dotted skyline of Cannes.

It was a fitting snapshot of the momentum behind Ethereum’s institutional rise and symbolic of Web3’s shift from niche experiment to financial mainstay.
