New Stirling Ultracold ULT Freezer Receives Lowest Validated Environmental Impact Score (in U.S.) from My Green Lab® ACT® Ecolabel as of March, 2025

STIRLING's VAULT100™ upright freezer receives ACT U.S. Environmental Impact Factor (EIF) score of 23—the lowest validated score of any ultra-low temperature (ULT) model listed in the ACT database as of today.
ATHENS, Ohio, March 28, 2025 /PRNewswire/ -- Stirling Ultracold, innovative developer and manufacturer of ULT freezers, today announced completion of its ACT Ecolabel audit by My Green Lab and inclusion of the company's new VAULT100 upright ULT freezer in the ACT database, with total EIF scores of 23, 35.3 and 35.4 for the US, EU and UK respectively. This represents a notable improvement in third-party validated EIF from Stirling's previous upright model and demonstrates the company's commitment to quantifiable environmental performance improvements in the lab equipment and ULT markets.
'It's very gratifying to see our latest effort to reduce ULT environmental impacts being validated by a respected lab sustainability advocate like My Green Lab,' noted Stirling Ultracold CEO, Clayton Newman. 'The VAULT100 builds on our sustainability legacy and 360-degree approach, which the ACT Ecolabel EIF recognizes through an industry-standard scoring process.'
Recently replacing the company's SU780XLE upright model with the same storage capacity and matching external dimensions, the VAULT100 is the first freezer in the industry with a -100°C to -20°C temperature range and features temperature uniformity of +/-3°C at -80°C throughout the interior cabinet. The wider temperature range gives customers more storage choices without compromising energy efficiency and is ideal for labs that frequently access samples from the freezer. Operating at the -100°C setpoint, the VAULT100 interior cabinet remains below -70°C when the door is open for up to 2 minutes.
Stirling Ultracold revolutionized the ultra-low freezer market in 2011 with the commercial introduction of the company's free-piston Stirling engine cooling technology, a more energy-efficient alternative to traditional compressor-based systems. The VAULT100 is powered by the new M6D Stirling engine that builds on those original advantages with a more robust design and new linear motor that allows lower power consumption at the control board. The M6D engine improves system reliability and energy efficiency over previous Stirling designs, allowing the VAULT100 to use only 5.8 kWh/day (steady-state) with a Maximum Daily Energy Consumption (MDEC) of 0.22 kWh/day/cu-ft, validated by ENERGY STAR®-certification.

Former EPA administrator, activists react to 'One Big Beautiful Bill'

As President Donald Trump touts a bill currently making its way through Congress as a win for the public, a former regional Environmental Protection Agency administrator is prepared to see devastating cuts to the office that could negatively impact human health. 'It's proposing severe cuts to both the scientific work that EPA's Office of Research and Development does and to the agency as a whole,' said Debra Shore, former administrator for EPA Region 5. 'It would severely reduce the agency's ability to fulfill its mission of protecting public health and the environment.' As the 'One Big Beautiful Bill' Act has passed the U.S. House of Representatives and moved to the Senate, activists nationwide have worried about the consequences. Shore said it's heartbreaking to see public servants at the EPA go through these cuts, especially as the administration tries to make the 'One Big Beautiful Bill' seem like a win. 'I have never worked with a group of such smart, devoted professionals who had a shared sense of mission as EPA employees,' Shore said. 'I know that's the case across the agency. … They could be working for far higher salaries in many cases, but they are dedicated to the foundational mission of the EPA, which is to protect public health and the environment.' On Tuesday and Wednesday, the EPA posted on Facebook, saying it 'delivers for all Americans.' 'One Big Beautiful Bill is putting American workers, taxpayers and families first,' the EPA's Tuesday post said. 'Under (Trump), the U.S. can unleash American energy while ensuring we have the cleanest air, land and water on (Earth).' The bill eliminates hundreds of billions of dollars in Green New Deal tax credits, repeals former President Joe Biden administration's electric vehicle mandates, and opens federal lands and waters to oil, gas, coal, geothermal and mineral leasing, according to the EPA's Tuesday post. According to the Wednesday post, the bill also 'streamlines onerous permitting processes,' refills the Strategic Petroleum reserve and 'delivers certainty to energy producers, saves and creates energy jobs, lowers energy costs for families.' A spokesperson for Sen. Todd Young, R-Indiana, provided a statement about the bill Friday. 'Senator Young continues to have conversations with his colleagues and stakeholders about improving the House-passed bill and addressing our nation's debt and deficit challenges,' said Leah Selk, spokesperson for Young. Representatives for Sen. Jim Banks, R-Indiana, did not respond to a request for comment Friday. Within the bill, the White House would also have the ability to cut federal agencies and reduce workforce, Shore said. 'This is just an utter abrogation of Congress' authority and power,' Shore said. 'It requires an annual report of planned reorganizational moves, and it also streamlines the ability of any future president to rebuild federal agencies because of some of the language in it.' Susan Thomas, director of policy and press for Just Transition Northwest Indiana, said it's concerning that EPA is treating the 'One Big Beautiful Bill' like a win, especially on social media platforms that are easily accessible. 'No one can take any information for granted anymore,' Thomas said. 'You must do your own research with trusted sources because the amount of greenwashing that's coming down is so dangerous. … This is becoming increasingly difficult, but it's more important than ever.' Thomas and Gary Advocates for Responsible Development board member Carolyn McCrady are both worried about the effects that environmental justice communities will face if the bill passes the Senate. McCrady expects public health to worsen as a result of EPA rollbacks. An October report from Industrious Labs found that most residents in Gary are in the top 10% of U.S. residents most at-risk for developing asthma and at-risk of low life expectancy. In 2020, Indiana had a lung cancer rate of 72.5 per 100,000 people, with Lake County as one of the state's counties with the highest cancer mortality rates, according to the American Lung Association. A 2016 JAMA Network report also found Gary as one of the top five U.S. cities with the lowest life expectancy at one point. 'I think people are going to be sicker faster,' McCrady said. 'I don't think people will be able to be served in the medical community in the same way, because in Indiana, millions of people are going to lose their health insurance because of the Medicaid cuts.' Although McCrady believes the EPA cuts are devastating, she isn't surprised to see them included in 'One Big Beautiful Bill.' Cuts will continue to put communities like Gary at a greater disadvantage, McCrady said. Thomas also believes that Northwest Indiana's environmental justice communities will struggle as a result of the 'One Big Beautiful Bill.' 'They've already stripped away all of the environmental justice provisions that had taken years to recognize and acknowledge and to start to put in place,' Thomas said. 'This is just a very sad state that we're in.'

Pelosi added millions to net worth last year: report

She might be the She-Wolf of Wall Street. Rep. Nancy Pelosi (D-California) raked in between $7.8 and $42.5 million in 2024 — meaning her estimated net worth with venture capitalist hubby Paul Pelosi could now top out at $413 million, new financial disclosures showed. The staggering sum is an eye-popping jump from 2023, when financial disclosures showed the couple's net worth topping out at a possible $370 million. Advertisement 4 The Pelosi's added between $7.8 and $42.5 million to their net worth in 2024. Getty Images Pelosi's exact net worth is not known because lawmakers are only required to disclose ranges. Market research firm Quiver Quantitative, which estimates a single figure based on daily stock values it tracks, placed the pair's 2024 worth at $257 million — up $26 million from a year earlier. Advertisement But the value of their various other ventures — which include but are not limited to a Napa Valley winery, ownership in a political data and consulting firm and a stake in a Bay area Italian restaurant — mean Pelosi's worth could be far higher in the estimated range. A large chunk of the couple's fortune has come from a sizable stock portfolio and timely trades, all done in Paul Pelosi's name. The former House Speaker, who's so infamous for trading Missouri Rep. Josh Hawley named a bill after her, and her husband dumped 5,000 shares of Microsoft stock worth an estimated $2.2 million in July — one of their largest sales in three years — a few short months before the FTC announced an antitrust investigation into the tech giant. They also sold 2,000 shares — worth an estimated $525,000 — of Visa stock, less than three months before the credit card company was hit with a DOJ monopoly lawsuit. Advertisement 4 Some have nicknamed Pelosi the 'Queen of Stocks.' Getty Images for The Museum of Contemporary Art (MOCA) Their best trade though might have been exercising a call option in December they bought in late 2023 at an estimated premium of $1.8 million, allowing them to nab 50,000 shares of hot AI chip stock NVIDIA for $12 a pop — less than one tenth of its market price. In total the couple paid an estimated $2.4 million for the investment, which on paper is now worth more than $7.2 million. NVIDIA wasn't their only AI play of 2024. Advertisement The couple also paid between $600,000 and $1.25 million for a call option on California cybersecurity company Palo Alto Networks in February, the same week it was revealed the White House briefed lawmakers on a serious national security threat related to Russia. The shares rose close to 20% in the days after the move. 4 A bill aiming to ban lawmakers and their spouses from trading individual stocks was named 'The PELOSI Act.' Jack Forbes / NY Post Design The option allowed the pair to scoop up 14,000 shares of Palo Alto in December at a $100 strike price — half its trading value. The company has been crushing earnings over the past year and the investment is now worth around $2.8 million. But the Queen of Stocks did suffer one setback — when she and Paul Pelosi ditched 2,500 shares of former Department of Government Efficiency boss Elon Musk's Tesla in June, losing somewhere between $100,000 and $1 million on the trade. In all, their investment portfolio pulled in an estimated 54% return in 2024, more than double the S&P 500's 25% gain — and beating every large hedge fund, according to numbers in Bloomberg's end-of-year tally of hedge funds' returns. 4 Pelosi and her good fortune have been at the center of arguments about why Congress shouldn't be allowed to trade stocks. Ron Sachs – CNP for NY Post The formidable profits come amid growing calls to ban Congress from trading individual stocks, arguing lawmakers have access to market-moving information ahead of the public. Advertisement Pelosi in the past rejected calls for a ban, stating 'we're a free‑market economy.' She has since softened her stance in the face of growing criticism. When asked in May whether Congress should pass a trading ban, she replied, 'If they do, they do.' 'Speaker Pelosi does not own any stocks, and she has no prior knowledge or subsequent involvement in any transactions,' a spokesperson told The Post. The couple is already off to a rocking 2025. Advertisement In January, they bought call options for then-little-known artificial intelligence health firm, Tempus AI, which has since inked a $200 million deal with AstraZeneca and doubled its stock price. The couple also took out call options for energy company Vistra — whose stock climbed last month after it unveiled a massive $1.9 billion deal to acquire natural gas facilities across the country from a private equity firm, citing rising US power demand.

Jetoptera Executes FETT for FTC-250 at Paris Air Show 2025

PARIS, June 21, 2025 (GLOBE NEWSWIRE) — On the occasion of Jetoptera's debut at the Paris Air Show 2025, we are proud to announce the successful completion of the first test of the engine that will power the J-500, the 500-lb VTOL cargo unmanned aircraft system Jetoptera is developing in collaboration with Eanan Al Samma, for the United Arab Emirates (UAE) market. The First Engine To Test (FETT) was evaluated at the VAN DER LEE Turbo Systems facilities in Zaandam, The Netherlands. The 250 kW turbocompressor, that is the heart of the Fluidic Propulsive System™, is a two-shaft engine using a free turbine that is mechanically coupled to a two-stage axial compressor designed to produce the appropriate flow rates and pressure ratios required by the FPS™. 'The FETT demonstrated a very smooth startup and operability when operated in a turbofan mode. The engine was instrumented in this configuration, to monitor pressure and temperature as well as thrust produced. The next step includes the performance mapping of the turbocompressor, followed by the integration with the FPS™ onto the J-500 airframe,' said Dr Andrei Evulet, CEO/CTO of Jetoptera, Inc. The J-500 prototype is developed specifically for the UAE and MENA market and will be uniquely enabled by the FPS™ to perform unmanned cargo missions with VTOL and unmatched speed, low noise, and reliability thanks to the patented propulsion system. The modularity of the FTC-250 system allows its components to operate in turbojet, turbofan and FPS™ modes. Jetoptera and Eanan Al Samma thank Parametric Solutions, Inc. and VAN DER LEE Turbo Systems for their critical support in the design and manufacturing of the unique FTC-250 architecture in record time.
