Much of the government’s case against Sam Bankman-Fried hinges on the testimony and text messages from those in his crypto inner circle who turned against him late last year after the implosion of FTX and sister hedge fund Alameda Research.
Of the dozens of items entered into evidence in the first three weeks of the trial, a bank of messages on encrypted app Signal paint perhaps the clearest picture of Bankman-Fried’s alleged crimes.
Bankman-Fried faces seven criminal counts, including wire fraud, securities fraud and money laundering that could land him in prison for life. Bankman-Fried, the son of two Stanford legal scholars, pleaded not guilty to all charges.
In trying to prove its case to a Manhattan jury, the government has presented a series of Signal exchanges involving Bankman-Fried, Caroline Ellison (his ex-girlfriend and the ex-CEO of Alameda Research), and former friends and top business execs Gary Wang, Nishad Singh and Ryan Salame. They date back to November 2021.
The messages gave jurors a rare look inside the casual conversations that culminated in a scheme described by U.S. Attorney Damian Williams as “one of the biggest financial frauds in American history.”

‘Small group chat’
The Signal thread dubbed “small group chat” includes Ellison, Bankman-Fried, and Joe Bankman, the defendant’s father who advised the company on tax-related issues and other things. Also in the group were Ramnik Arora, a former product lead for FTX, Ryne Miller, who was the company’s general counsel, Constance Wang, ex-operating chief, as well as Salame, Singh, Wang and four others.

The thread begins with two messages from Bankman-Fried posted at 3:47 a.m. on Nov. 7, 2022, the day FTX announced a liquidity crisis and began searching for cash to plug the gaping hole in its balance sheet.
At the time, Bankman-Fried pretended in public that all was well.
“FTX is fine. Assets are fine,” he wrote in a tweet that day. The post has since been deleted.
But as Bankman-Fried was tweeting reassurances and promising that customer funds were safe, executives were growing increasingly alarmed at the expanding shortfall, according to prosecutors.
In the “small group chat” thread, Bankman-Fried put forth some “potential todos,” including halting withdrawals, sending a “confident tweet thread” and reaching out to firms like Silverlake, Sequoia, and Apollo as they “wake up over the next few hours” to try and shore up cash.
Later that morning, at about 5:22 a.m., Salame linked to a tweet from an anonymous crypto trader saying, “cant wait for my FTX airdrop for not moving any of my funds.”
Bankman-Fried chimed in with different ideas about how to take advantage of the post in an apparent effort to provide false hope to FTX customers that they’d receive free tokens if they kept their funds on the platform.

The next day, Nov. 8, Ellison appealed to the group for help on optics and public messaging.
She wrote, “multiple people internally asking me whether they should continue to make statements to external parties like ‘Alameda is solvent.’ should i suggest they stall instead? just stall on responding to their messages? or what?”
That’s the same day FTX issued a pause on all customer withdrawals. The price of FTT, FTX’s native token, plummeted by over 75%, and a high-tech bank run was in full force. Out of options, Bankman-Fried turned to Binance CEO Changpeng Zhao, who announced he’d signed a non-binding letter of intent to acquire FTX.

On Nov. 9, Ellison again looked to the group for guidance about how to handle the now infamous all-hands meeting of Alameda’s roughly 30 employees.
She proposed saying, “Alameda is probably going to wind down” and that there was “no pressure” to stay but help with “stuff like making sure our lenders get paid” would be “super appreciated.”
Bankman-Fried suggested she say something about there “being a future of some sort for those who are excited.”
Ellison ended up divulging a lot more than that in the staff meeting.
“Alameda borrowed a bunch of money,” which it used to make investments, Ellison said at the meeting, a secret recording of which was played by the prosecution. But as crypto prices fell, “FTX had a shortfall of user funds” and then “users started withdrawing their funds” and they “realized they would not be able to continue.”
When she was asked by a staffer whose idea it was to plug Alameda’s loan losses with FTX customer money, she said, “Um, Sam, I guess,” and giggled.
“FTX basically always allowed Alameda to, like, borrow user funds, as far as I know,” Ellison said on the recording.
Meanwhile, a day after signing the non-binding purchase agreement, Binance withdrew the offer, citing reports of “mishandled customer funds” and federal investigations.

‘Lots of withdrawals’
Zhao, an early investor in FTX before becoming a principal rival, had made himself a central character in the FTX downfall days earlier.
On Nov. 6, he tweeted that because of “recent revelations that have came [sic] to light, we have decided to liquidate any remaining FTT on our books.”
In a group chat with Bankman-Fried, Ellison, and Singh starting that day, Singh wrote “lots of withdrawals on ftx are queueing up,” with net changes of $1.25 billion in the last day, $230 million in the last three hours, and $120 million in the last hour.
Ellison responded with a “:(” and Bankman-Fried with an “oof” after first mistakenly writing “of.”
The three continued to strategize. Singh suggested a few hours later that they reach out to Zhao privately and “ask for a truce” to “stem the bleed,” though he and Bankman-Fried both worried that Binance wouldn’t deescalate in public.
Ellison separately tried to figure out what to tell Salame about whether FTX could meet all withdrawals. Bankman-Fried suggested she write, “we can meet a ton, though it’s already getting large.”

Later, Sam Trabucco, who had already departed as co-CEO of Alameda Research in August 2022, as well as Ellison, Ben Xie (Alameda’s head of trading), and Bankman-Fried, were in a group chat discussing how to respond to Zhao’s threat to liquidate his FTT tokens.
Ellison, who told jurors that she largely avoided social media, said she would tweet at CZ, a nickname for Zhao, that FTX would buy his entire stake at $22 per coin. Ellison also testified about the practice of using FTX customer funds funneled through Alameda to buy FTT to buoy the price during times of market volatility.

Bankman-Fried weighed in within minutes, writing, “I think the main point is just to counter the PR/narrative here — and Binance probably won’t take us up on it; I also think FWIW that the market is likely to buy more if we tweet it, but idk.” (FWIW is an acronym for for what it’s worth. IDK stands for I don’t know.)

The author’s visit
Author Michael Lewis, whose book profiling Bankman-Fried was published the day the trial began, was also the subject of some Signal exchanges.
In a chat on Jan. 5, 2022, Bankman-Fried alerted a group that included Ellison and Singh that Lewis would be coming to the Bahamas the next month to do reporting.
Ellison said her “instincts are more toward under the radar.” Bankman-Fried, a notorious press hound, responded, “same, except exactly the opposite.”
‘People of the House’
Adam Yedidia, one of the prosecution’s lead witnesses, met Bankman-Fried in college at the Massachusetts Institute of Technology, and the pair remained close friends.
In his testimony, Yedidia referred to a Signal thread called “People of the House,” referring to Bankman-Fried’s $35 million penthouse, where many employees lived.
In terms of who was paying the rent, Yedidia recalled Bankman-Fried saying he “assumed it’s just alameda paying for it in the end.”

The subject of campaign donations was pivotal to Singh’s testimony. The former FTX engineering chief, who pleaded guilty to six charges in February, alleged that his former boss was behind much of the scheme to funnel money to political campaigns.
Singh testified that Bankman-Fried directed money held in accounts belonging to Alameda Research be used for political donations. That continued even after Bankman-Fried was apparently aware that his crypto hedge fund couldn’t pay back the $13 billion in FTX customer funds it had borrowed.
While Bankman-Fried doesn’t face chares for campaign violations in this trial, a superseding indictment alleged he used customer funds to make more than $100 million in campaign contributions for the 2022 midterm elections. The government has incorporated that accusation within two of the charges that are still standing: wire fraud and money laundering.

‘Donation Processing’
Singh walked the jury through how the process worked.
He described a Signal chat dubbed “Donation Processing” that included Bankman-Fried and his brother, Gabe, Salame, and a political consultant named Michael Sadowsky, among others. Singh testified that Bankman-Fried or his brother would use this chat to request donations be made in Singh’s name. Salame, who had access to Singh’s bank account at Prime Trust Bank, would set up the transfer and then ping Singh in the channel to prompt him to go to his email and approve the wire request.
“My role was to click a button,” Singh said of the operation, adding that Salame had other ways to make the transfer from Singh’s funds that did not involve Singh having to do anything at all.

In a separate Signal chat between Singh and Sadowsky, Singh wrote on Jul. 5, 2022, that he was “averse” to “explicitly-woke stuff” but added that it was “hard to interact productively with democrats without that.”
Sadowsky called Singh the “center left face of our spending,” meaning that he would be “giving to a lot of woke s—.”
So, “if you’re not comfortable about it, you should think about that a lot,” wrote Sadowsky.
Singh responded, “don’t love boxing myself into only associating with people i don’t like” and said he would look to see if there were “other viable people at FTX for it.”
In questioning witnesses, the government homed in on loans made to Wang and Singh in the range of hundreds of millions of dollars.
Direct messages between Singh and Bankman-Fried showed an attempt by the witness to be cleared of these debt obligations.
In a direct appeal to Bankman-Fried, Singh wrote on Nov. 6, 2022, “one thing that’d seriously help me is if I didn’t have debts.”
He wrote, “I think most of them are loans: 500m for me exercising, more for US investments. I hope we can unwind these but not sure.” He said he would return anything he had in his bank account, but there wasn’t much there.
I “(will think about this),” Bankman-Fried wrote.

In the same thread, on Nov. 8, Singh wrote that Ryne Miller, FTX’s general counsel, seemed “super on edge” and “likely to resign” if they didn’t get it right.
Singh wrote, “this is wildly selfish of me, but they may need to know that it wasn’t a ton of people orchestrating it.” He added that, “it makes them more likely to want to be here to help save the situation and the others at least.”

As the grand scheme collapsed, Ellison expressed a great deal of relief in a private chat with Bankman-Fried.
Ellison wrote, “this is the best mood I’ve been in in like a year tbh.” (TBH is short for to be honest.)
In three consecutive messages, Bankman-Fried responded, “wow,” “uh,” “congrats?”
Ellison wrote, “I think I just had an increasing dread of this day that was weighing on me for a long time, and now that it’s actually happening, it just feels great to get it over with one way or another.”

‘Repowering’ era for America’s aging wind energy industry begins, despite Trump’s effort to kill it
Jeffrey Sanders / 500px | 500px | Getty Images
On Inauguration Day, President Donald Trump issued an executive order indefinitely halting permits for new onshore wind energy projects on federal land, as well as new leases for offshore wind farms in U.S. coastal waters. The action not only fulfilled Trump’s “no new windmills” campaign pledge, but struck yet another blow to the wind industry, which has been hit hard over the past few years by supply chain snags, price increases upending project economics, public opposition and political backlash against federal tax credits, especially those spurring the fledgling offshore wind sector.
Nonetheless, the nation’s well-established onshore wind industry, built out over several decades, is generating nearly 11% of America’s electricity, making it the largest source of renewable energy and at times last year exceeding coal-fired generation. On April 8, the fossil-fuels-friendly Trump administration took measures to bolster coal mining and power plants, but as the infrastructure driving wind energy ages, efforts to “repower” it are creating new business opportunities for the industry’s key players.
This repowering activity has emerged as a bright spot for the wind industry, giving a much-needed boost to market leaders GE Vernova, Vestas and Siemens Gamesa, a subsidiary of Munich-based Siemens Energy. Following several challenging years of lackluster performance — due in particular to setbacks in both onshore and offshore projects — all three companies reported revenue increases in 2024, and both GE Vernova and Siemens stock have moved higher.
GE Vernova, spun off from General Electric a year ago, led overall onshore wind installations in 2024, with 56% of the U.S. market, followed by Denmark’s Vestas (40%) and Siemens Gamesa (4%).
GE Vernova stock performance over the past one-year period.
According to the U.S. Energy Information Administration, installed wind power generating capacity grew from 2.4 gigawatts (GW) in 2000 to 150.1 GW as of April 2024. Although the growth rate for launching new greenfield onshore wind farms has slowed over the last 10 years, the U.S. is still poised to surpass 160 GW of wind capacity in 2025, according to a new report from energy research firm Wood Mackenzie.
There currently are about 1,500 onshore wind farms — on which more than 75,600 turbines are spinning — across 45 states, led by Texas, Iowa, Oklahoma, Illinois and Kansas. Virtually all of the wind farms are located on private land, and many of the largest ones are owned and operated by major energy companies, including NextEra Energy, RWE Clean Energy, Pattern Energy, Clearway Energy, Xcel Energy and Berkshire Hathaway‘s MidAmerican Energy, which generates 59% of it renewable energy from wind, including 3,500 turbines operating across 38 wind projects in Iowa.
A growing number of the turbines are 20-plus years old and nearing the end of their lifecycle. So increasingly, operators have to decide whether to upgrade or replace aging turbines’ key components, such as blades, rotors and electronics, or dismantle them altogether and erect new, technologically advanced and far more efficient models that can increase electricity output by up to 50%.
“What’s becoming clear is that more and more of the U.S. installed base [of onshore turbines] has exceeded its operational design life,” said Charles Coppins, research analyst for global wind at Wood Mackenzie, “and now operators are looking to replace those aging turbines with the latest [ones].”
To date, approximately 70 GW of onshore wind capacity has been fully repowered in the U.S., according to Wood Mackenzie, while an additional 12 GW has been partially repowered. The firm estimates that around 10,000 turbines have been decommissioned and that another 6,000 will be retired in the next 10 years, Coppins said.

Beyond the fact that aged-out turbines need to be upgraded or replaced, repowering an existing wind farm versus building a new site presents economic benefits to operators and OEMs. To begin with, there’s no need to acquire property. In fact, in certain situations, because today’s turbines are larger and more efficient, fewer turbines are needed. And they’ll generate additional electricity and have longer lifecycles, ultimately delivering higher output at a lower cost.
Even so, “there are some limitations on how much capacity you could increase a project by without having to go through new permitting processes or interconnection queues” to the power grid, said Stephen Maldonado, Wood Mackenzie’s U.S. onshore analyst. As long as the operator is not surpassing the allowed interconnection volume agreed to with the local utility, they can add electricity to the project and still send it to the grid.
Public opposition, Maldonado said, may be another hurdle to get over. Whether it’s a new or repower wind project, residents have expressed concerns about environmental hazards, decreased property values, aesthetics and general anti-renewables sentiment.
RWE, a subsidiary of Germany’s RWE Group, is the third largest renewable energy company in the U.S., owning and operating 41 utility-scale wind farms, according to its CEO Andrew Flanagan, making up 48% of its total installed operating portfolio and generating capacity, which also includes solar and battery storage.
One of RWE’s two repower projects underway (both are in Texas), is its Forest Creek wind farm, originally commissioned in 2006 and featuring 54 Siemens Gamesa turbines. The project will replace them with 45 new GE Vernova turbines that will extend the wind farm’s life by another 30 years once it goes back online later this year. Simultaneously, RWE and GE Vernova are partnering on a new wind farm, immediately adjacent to Forest Creek, adding another 64 turbines to the complex. When complete, RWE will deliver a total of 308 MW of wind energy to the region’s homes and businesses.
Flanagan noted that the combined projects are related to increased electricity demands from the area’s oil and gas production. “It’s great to see our wind generation drive the all-of-the-above energy approach,” he said. What’s more, at its peak, the repower project alone will employ 250 construction workers and over its operating period bring in $30 million in local tax revenue, he added.
In turn, the twin projects will support advanced manufacturing jobs at GE Vernova’s Pensacola, Florida, facility, as well as advancing the OEM’s repower business. In January, the company announced that in 2024 it received orders to repower more than 1 GW of wind turbines in the U.S.

Siemens Gamesa has executed several large U.S. repowering projects, notably MidAmerican’s expansive Rolling Hills wind farm in Iowa, which went online in 2011. In 2019, the company replaced 193 older turbines with 163 higher-capacity models produced at its manufacturing plants in Iowa and Kansas.
Last year, Siemens Gamesa began repowering RWE’s 17-year-old Champion Wind, a 127-MW wind farm in West Texas. The company is upgrading 41 of its turbines with new blades and nacelles (the housing at the top of the tower containing critical electrical components) and adding six new turbines.
In early April, Clearway announced an agreement with Vestas to repower its Mount Storm Wind farm in Grant County, West Virginia. The project will include removing the site’s 132 existing turbines and replacing them with 78 new models. The repower will result in an 85% increase in Mount Storm’s overall electricity generation while using 40% fewer turbines.
Preparing for ‘megatons’ of turbine recycling and tariffs
Another benefit of repowering is invigorating the nascent industry that’s recycling megatons of components from decommissioned turbines, including blades, steel, copper and aluminum. Most of today’s operational turbines are 85% to 95% recyclable, and OEMs are designing 100% recyclable models.
While the majority of mothballed blades, made from fiberglass and carbon fiber, have historically ended up in landfills, several startups have developed technologies recycle them. Carbon Rivers, for example, contracts with the turbine OEMs and wind farm operators to recover glass fiber, carbon fiber and resin systems from decommissioned blades to produce new composites and resins used for next-generation turbine blades, marine vessels, composite concrete and auto parts.
Veolia North America, a subsidiary of the French company Veolia Group, reconstitutes shredded blades and other composite materials into a fuel it then sells to cement manufacturers as a replacement for coal, sand and clay. Veolia has processed approximately 6,500 wind blades at a facility in Missouri, and expanded its processing capabilities to meet demand, according to David Araujo, Veolia’s general manager of engineered fuels.
Trump’s new-project moratorium isn’t his only impediment to the wind industry. The president’s seesaw of import tariffs, especially the 25% levy on steel and aluminum, is impacting U.S. manufacturers across most sectors.
The onshore wind industry, however, “has done a really good job of reducing geopolitical risks,” said John Hensley, senior vice president for markets and policy analysis at the American Clean Power Association, a trade group representing the clean energy industry. He cited a manufacturing base in the U.S. that includes hundreds of plants producing parts and components for turbines. Although some materials are imported, the investment in domestic manufacturing “provides some risk mitigation to these tariffs,” he said.
Amidst the headwinds, the onshore wind industry is trying to stay focused on the role that repowering can play in meeting the nation’s exponentially growing demand for electricity. “We’re expecting a 35% to 50% increase between now and 2040, which is just incredible,” Hensley said. “It’s like adding a new Louisiana to the grid every year for 15 years.”
GE Vernova CEO Scott Strazik recently told CNBC’s Jim Cramer that the growth of the U.S.’s electric load is the largest since the industrial boom that followed the end of the second world war. “You’ve got to go back to 1945 and the end of World War II, that’s the infrastructure buildout that we’re going to have,” he said.
As OEMs and wind farm developers continue to face rising capital costs for new projects, as well as a Trump administration averse to clean energy industries, “repowering offers a pathway for delivering more electrons to the grid in a way that sidesteps or at least minimizes some of the challenges associated with all these issues,” Hensley said.
Capable of delivering up to 1,200 kW of power to get electric commercial trucks back on the road in minutes, the new ABB MCS1200 Megawatt Charging System is part of an ecosystem of electric vehicle supply equipment (EVSE) that ABB’s bringing to this year’s ACT Expo.
ABB E-mobility is using the annual clean trucking conference to showcase the expansion of its EVSE portfolio with three all-new charger families: the field-upgradable A200/300 All-in-One chargers, the MCS1200 Megawatt Charging System for heavy-duty vehicles shown (above), and the ChargeDock Dispenser for flexible depot charging.
The company said its new product platform was built by applying a computer system-style domain separation to charger design, fundamentally improving subsystem development and creating a clear path forward for site and system expansion. In other words, ABB is selling a system with both future-proofing and enhanced dependability baked in.
“We have built a system by logically separating a charger into four distinct subsystems … each functioning as an independent subsystem,” explains Michael Halbherr, CEO of ABB E-mobility. “Unlike conventional chargers, where a user interface failure can disable the entire system, our architecture ensures charging continues even if the screen or payment system encounters issues. Moreover, we can improve each subsystem at its own pace without having to change the entire system.”
The parts of ABB’s new EVSE portfolio that have been made public so far have already been recognized for design excellence, with the A400 winning the iF Gold Award and both the A400 and C50 receiving Red Dot Design Awards.
New ABB chargers seem pretty, good
ABB says the systemic separation of its EVSE enhances both reliability and quality, while making deployed chargers easier to diagnose and repair, in less time. Each of the chargers’ subsystems can be tested, diagnosed, and replaced independently, allowing for quick on-site repairs and update cycles tailored to the speed of each systems’ innovation. The result is 99% uptime and a more future-proof product.
“The EV charging landscape is evolving beyond point products for specific use cases,” continued Halbherr. “By implementing this modular approach with the majority of our R&D focused on modular platforms rather than one-off products … it reduces supply chain risks, while accelerating development cycles and enabling deeper collaboration with critical suppliers.”
Key markets ABB is chasing
- PUBLIC CHARGING – with the award winning A400 being the optimal fit for high power charging from highway corridors to urban locations, the latest additions to the A-Series All-in-One chargers offer a field-upgradable architecture allowing operators to start with the A200 (200kW) with the option to upgrade to 300kW or 400kW as demand grows. This approach offers scalability and protects customer investment, leading to Total Cost of Ownership (TCO) savings over 10 years.
- PUBLIC TRANSIT AND FLEET – the new Charge Dock Dispenser – in combination with the already in market available HVC 360 – simplifies depot charging with a versatile solution that supports pantograph-, roof-, and pedestal charging options with up to 360kW of shared power and 150m/490 ft installation flexibility between cabinet and dispensers. The dispenser maintains up to 500A output.
- HEAVY TRUCKS – building the matching charging infrastructure for commercial vehicles and fleets represents a critical innovation frontier on our journey to electrify transportation. Following extensive collaboration with industry-leading truck OEMs, the MCS1200 Megawatt Charging System delivers up to 1,200kW of continuous power — 20% more energy transfer than 1MW systems — providing heavy-duty vehicles with purpose-built single-outlet design for the energy they need during mandatory driver breaks. To support other use cases, such as CCS truck charging, a dual CCS and MCS option will also be available.
- RETAIL – the award winning C50 Compact Charger complements the family as the slimmest charger in its category at just 9.3 inches depth, optimized for convenient charging during typical one-hour retail experiences. With its large touch display, the C50 takes the award-winning A400 experience even further — setting a new standard for consumer experience and very neatly echoing our own take on that “Goldilocks” timing zone for commercial charging.
ABB says that the result of its new approach are chargers that offer 99% plus uptime — a crucial statistic for commercial charging operations and a key factor to ensuring customer satisfaction. The new ABB E-mobility EVSE product family will be on display for the first time at the Advanced Clean Transportation Expo (ACT Expo) in Anaheim, California next week, then again at Power2Drive in Munich, Germany, from May 7-9.
Electrek’s Take
The ACT Expo is one of – if not the most important sustainable trucking event in North America, featuring all the big names in heavy trucks, construction equipment, material handling, infrastructure – even Tier 1 suppliers. Mostly, though, it’s many fleet buyers’ only chance to test drive these zero emission trucks before writing a big PO (which just makes it even more important).
Electrek will be there again this year, and we’ll be bringing you all the latest news from press events and product reveals as it happens.

Along with Tennessee Tech, Tennessee-based ultralight aircraft company Whisper Aero has secured a $500,000 grant to help advance the company’s innovative electric jet motor concept off the drawing board and onto the testing phase.
Earlier this month, the Tennessee Department of Economic and Community Development (TNECD) announced plans to award $500,000 to Tennessee Tech and Whisper Aero through the Transportation Network Growth Opportunity (TNGO) initiative.
“We look forward to using these award dollars to place students in internships working directly with Whisper Aero leaders,” said Tennessee Tech President Phil Oldham. “By learning from an electric propulsion innovator like Whisper Aero, our students will gain invaluable perspective and can take what they have learned in the classroom and apply it right here in Tennessee.”
The grant will see a Whisper Aero glider fitted with a pair of the company’s eQ250 electric-powered jet “propulsors” for UltraQuiet flight. Tennessee Tech faculty and students will carry out copper-bird ground testing to ensure the safe integration of engines, batteries, and controllers, and kickstart Tennessee Tech’s new Crossville Mobility Incubator.
Those propulsors, by the way, are super cool.
Whisper Aero’s main claim to fame is its innovative UltraQuiet WhisperDrive (above). It’s effectively an electrically spun ducted fan jet engine that uses a large number of stiff composite fan blades inside a lightweight, acoustically treated duct. With so many blades, the Whisper Aero propulsor can push more air than a conventional prop while spinning much more slowly. As such, the “blade passage frequency” moves up to more than 16,000 Hz – outside the range of most human hearing but not, supposedly, high enough to freak out the beagles.
The Whisper Aero ultralight is effectively an Aériane Swift3 glider fitted with a pair of Whisper’s eQ250 propulsors, each capable of up to 80 lbs. of thrust. The Ultralight has a wingspan of over 40 ft with a maximum L/D of 35:1 and can be stressed to a design loading of +6/-4g, making it capable of some pretty impressive acrobatic feats.
The Swift3 glider is designed for a low speed, low power cruising speed of 45–55 knots with “just” 6.5 hp. Power-off glides from a few hundred feet showed a low sink rate, and a climb rate of 1,250 ft/min with full self-launching power (in other words: the Whisper glider doesn’t have to be towed by a launch vehicle, like a conventional ultralight glider).
Quiet cool
Range under full power is about 109 miles with current battery tech, but it’s expected that range under the latest EPiC 2.0 energy batteries would rise to nearly 170 miles.
Nathan Millecam, CEO of Electric Power System, said, “EPiC 2.0’s leap in energy density and thermal performance has enabled a significant increase in range, a clear validation of our next-gen cell technology. We are impressed by what the Whisper team continues to achieve in advancing electric aviation.”
The press release concludes explaining that flight tests are expected to show that the Whisper Aero glider can be flown, “a few hundred feet away from neighborhoods without any disturbances, while carrying a 220 lbs. payload with full range,” which is all kind of ominous in today’s political climate, but still pretty neat from a purely tech perspective.
The TNGO grant follows a separate grant from NASA awarded last year, though that grant aims to develop the eQ250s – not as a propulsion system, but as a key component in future spacecraft ventilation systems.
Tennessee Tech announces TNGO grant
With support from TNECD’s Transportation Network Growth Opportunity (TNGO) initiative, Tennessee Tech University and Whisper Aero are partnering to advance next-generation propulsion technology in the aerospace industry. This collaboration will enhance aerospace research and workforce development, ensuring Tennessee remains a leader in cutting-edge mobility solutions.
