Whisper Aero ultralight aircraft scores $500K for “UltraQuiet” electric jet motor tests
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.

Enbridge is going big on solar again in Texas, and Meta is snapping up all the solar power it can get.
Last month, Electrek reported that the Canadian oil and gas pipeline giant just launched its first solar farm in Texas. Now it’s given the green light to Clear Fork, a 600 megawatt (MW) utility-scale solar farm already under construction near San Antonio. The project is expected to come online in summer 2027.
Once it’s up and running, every bit of Clear Fork’s electricity will go to Meta Platforms under a long-term contract. Meta will use the solar power to help run its energy-hungry data centers entirely on clean energy.
The solar farm project’s cost is around $900 million. Enbridge says it expects Clear Fork to boost the company’s cash flow and earnings starting in 2027.
Enbridge EVP Matthew Akman said the project reflects “growing demand for renewable power across North America from blue-chip companies involved in technology and data center operations.”
Meta’s head of global energy, Urvi Parekh, added that the company is “thrilled to partner with Enbridge to bring new renewable energy to Texas and help support our operations with 100% clean energy.”
Meta’s first multi-gigawatt data center, Prometheus, is expected to come online in 2026.
Clear Fork is part of a growing trend: tech giants like Meta, Amazon, and Google are racing to lock down renewable energy contracts as they expand their fleets of AI-ready data centers, which use massive amounts of electricity.
The 30% federal solar tax credit is ending this year. If you’ve ever considered going solar, now’s the time to act.

A fully electric Japanese electric pickup truck? It’s not a Toyota or Honda, but Isuzu’s new electric pickup packs a punch. The D-MAX EV can tow over 7,770 lbs (3,500 kg), plow through nearly 24″ (600 mm) of water, and it even has a dedicated Terrain Mode for extreme off-roading. However, it comes at a cost.
Meet Isuzu’s first electric pickup: The D-MAX EV
After announcing that it had begun building left-hand drive D-MAX EV models at the end of April, Isuzu said that it would start shipping them to Europe in the third quarter.
By the end of the year, Isuzu will begin production of right-hand drive models for the UK. Sales will follow in early 2026.
Isuzu announced prices this week, boasting the D-MAX EV features the same “no compromise durability” of the current diesel version.
The D-MAX EV pickup features a full-time 4WD system, a towing capacity of up to 3.5 tons (7,700 lbs), and an added Terrain Mode, which Isuzu says is designed for “extreme off-road capability.” With 210 mm (8.3″) of ground clearance, Isuzu’s electric pickup can wade through up to 600 mm (24″) of water.
Powered by a 66.9 kWh battery, Isuzu’s electric pickup offers a WLTP range of 163 miles. With charging speeds of up to 50 kW, the D-MAX EV can recharge from 20% to 80% in about an hour.
The electric version is nearly identical to the current diesel-powered D-Max, both inside and out, but prices will be significantly higher.

OpenAI and Anthropic continue to lead a fundraising bonanza in artificial intelligence, raising historic rounds and stratospheric valuations.
But when it comes to finding AI exits for venture firms, the market looks a lot different.
AI startups raised $104.3 billion in the U.S. in the first half of this year, nearly matching the $104.4 billion total for 2024, according to PitchBook. Almost two-thirds of all U.S. venture funding went to AI, up from 49% last year, PitchBook said.
The biggest deals follow a familiar theme. OpenAI raised a record $40 billion in March in a round led by SoftBank. Meta poured $14.3 billion into Scale AI in June as part of a way to hire away CEO Alexandr Wang and a few other top staffers. OpenAI rival Anthropic raised $3.5 billion, while Safe Superintelligence, a nascent startup started by OpenAI co-founder Ilya Sutskever, raised $2 billion.
While Meta’s massive investment into Scale AI amounted to a lucrative exit of sorts for early investors, the overarching trend has been a lot more money going in than coming out.
In the first half, there were 281 VC-backed exits totaling $36 billion, according to PitchBook. That includes the roughly $700 million acquisition of EvolutionIQ, an AI platform for disability and injury claims management, by CCC Intelligent Solutions, and the public listing of Slide Insurance, which builds AI-powered insurance offerings for homeowners. Slide is valued at about $2.3 billion.
“The dominant exit trend right now is frequent but lower-value acquisitions and fewer IPOs with significantly higher value,” said Dimitri Zabelin, PitchBook’s senior research analyst for AI and cybersecurity.
CoreWeave’s IPO, which took place at the very end of the first quarter, was the exception on the infrastructure side. The stock shot up 340% in the second quarter, and the company is now valued at over $63 billion.
Zabelin said the pattern of more investments in applications with smaller deals has been in place for the past year.
“Vertical solutions tend to plug more easily into existing enterprise gaps,” Zabelin said.
The acquisitions wave is being driven, in part, by what Zabelin calls bolt-on deals where larger companies buy smaller startups to enhance their own future valuations, hoping to enhance their value ahead of a future sale or IPO.
“That also has to do with the current liquidity conditions in the macro environment,” Zabelin said.
Outside of AI, activity is slow. U.S. fintech funding dropped 42% in the first half of the year to $10.5 billion, according to Tracxn. Cloud software and crypto have also seen sharp pullbacks.
Zabelin said IPO activity could pick up if economic conditions improve and if interest rates come down. Investors clearly want opportunities to back promising AI companies, he said.
“The appetite for AI, specifically vertical applications, will continue to remain robust,” Zabelin said.
