Tesla co-founder unveils electric garbage truck

Published

The global transition from combustion engine to all-electric vehicle continues to move into new sectors as Wrightspeed has just released its first fleet of range-extended electric refuse trucks. The powertrain represents a new era in vehicle propulsion, repowering a generation of lighter, quieter, and more efficient vehicle fleets for urban streets.

Wrightspeed’s commercial application of the range-extended, turbine-electric powertrain is the heavy-duty Class 8 Freightliner, which will be delivered to The Ratto Group, a Sonoma County solid waste collection and recycling business. The Class 8 Freightliner is the first of at least fifteen electric vehicles that will be integrated into the trash company’s fleet over the next year, according to Tim Dummer, Wrightspeed’s chief business officer. Dummer, an engineering and commercialization executive, was brought into Wrightspeed in October, 2016 as part of the company’s ramp-up of its Range-extended Electric Vehicle (REV) powertrain systems.

Called The Route, Wrightspeed’s REV powertrain is optimized for the refuse industry and can be customized to fit a variety of today’s heavy-duty truck platforms, replacing both the engine and the transmission. Much of the growing demand for the award-winning The Route is due to Wrightspeed’s founder, Ian Wright, one of the original co-founders of Tesla Motors. After his departure from Tesla Motors in 2003, Wright had a vision that electric vehicles could deliver high-performance without compromising intrinsic efficiency. Using turbines and applying electric vehicle principles to urban, heavy-duty trucks, The Route powertrain was the result.

The Wrightspeed system can power a 66,000-pound GVW truck, delivering up to 24 miles on battery power before the range extender kicks in. After that, range is nearly unlimited as long as there is fuel for the turbine. With fuel efficiency the equivalent of up to 7 mpg in combined electricity-liquid fuel operation, the powertrain can slash annual fuel consumption by 70 percent or more compared with the average diesel refuse truck. CEO Lou Ratto says he expects a fuel savings of at least 50 percent.

Eventually, all of Ratto’s 130 residential trash and recycling trucks may be retrofitted with the turbine-electric powertrain. This is an ambitious undertaking, as a refuse truck’s demanding duty cycle drains an electric powertrain’s batteries quickly.  Think start, then stop.  Start, stop. Wrightspeed’s electric powertrain drives more low-end torque to the wheels than conventional diesel engines, with less fuel, emissions, and noise.

Wrightspeed, in a sense, is recycling Ratto’s trash collection trucks. The Wrightspeed/ Ratto contract is thought to be in the range of $3 million to $5 million.

A new refuse truck that meets all California air quality standards costs more than $500,000, so Wrightspeed’s retrofit of Ratto’s existing trucks makes the system more cost-effective, Van Amburg relates. Sonoma County officials like the trash fleet electrification program because they see it as a means of improving local air quality, says Efren Carrillo, chairman of the Sonoma County Board of Supervisors. Ratto concurs. “Here in Sonoma County there is a lot of environmental consciousness, and we are always looking for ways to be cleaner, environmentally friendly, and help the bottom line. And the idea that [by electrifying the trucks] we can do this and get off the air quality rollercoaster and stop battling to meet California emissions requirements— that makes it all worthwhile.”

Wrightspeed featured its powertrain technology alongside Mack Trucks at Waste Expo 2016 in Las Vegas and signed a $30+ million agreement with NZ Bus, symbolizing multinational and multimodal demand for Wrightspeed’s powertrain technology. In June, the company was named a Technology Pioneer by the World Economic Forum (WEF), and CEO Wright was an invited presenter to the International Business Council of the World Economic Forum. He will be a keynote speaker at the upcoming SAE 2016 Range Extenders for Electric Vehicles Symposium in Knoxville, 2-3 November, 2016.

Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.

Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.

Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.

Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

Space finally faced the people living next to its next Terafab mega-project

SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.

SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.

The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.

Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry

Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.

SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.

SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.

Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.

SpaceX has solved Starship’s biggest challenge, Elon Musk says

Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.

During the company’s first-ever Earnings Call, the SpaceX CEO stated:

“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”

Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.

The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.

These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.

Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.

Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.

Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
