Daikin executives headline flagship grid-reliability panel on September 21

David Calabrese, Executive Vice President of Daikin U.S. Corporation, will join the Hub Live Flagship Session "Strait Talk, Reality Check: How Do We Keep the Lights on in an Uncertain World?" at The Glasshouse on September 21 at 1:00 p.m. Calabrese said buildings need smarter energy management and efficient HVAC technology to manage demand as electrification accelerates, rather than relying solely on new energy production.

Pasadena, Calif. – September 19, 2026 -- PrismML has released Bonsai 2 27B, a ternary-compressed version of a 27-billion-parameter multimodal model that runs at just 5.9 GB while retaining 98.2% of its full-precision counterpart's benchmark performance.

Ternary compression shrinks memory footprint by more than 9x

Built on Qwen3.8 27B, Bonsai 2 27B reduces the model's memory requirement to 5.9 GB, a reduction of over nine times compared with the full-precision original. The model contains 27.8 billion parameters and was trained using Google v5 TPUs.

Pittsburgh – – September 19, 2026 -- A Windsor, Ontario-based inventor has filed a patent-pending design for COOL SCREEN, a protective cover engineered to shield air conditioning units from weather exposure and debris clogs.

Design targets AC unit longevity and energy efficiency

The invention aims to reduce premature wear on outdoor AC units by blocking environmental debris that typically causes clogs and efficiency losses. By maintaining unobstructed airflow, the product could lower the energy costs tied to reduced compressor performance over time.

Product built for homeowner installation without technical expertise

COOL SCREEN features a durable construction designed for straightforward use, positioning it for the residential HVAC maintenance market. A prototype and technical drawings are available for review by interested manufacturers.

Turku, Finland – September 19, 2026 -- Teleste has expanded its passenger information portfolio with a new outdoor e-paper display family that cuts energy consumption by up to 50% compared with comparable battery-powered e-paper solutions on the market.

Battery-powered displays can operate for up to 10 years without replacement

Depending on system configuration and operating profile, the displays support a battery lifetime of up to 10 years, running on battery or solar power. This lets public transport operators deploy real-time passenger information at remote and temporary stops that previously lacked power infrastructure or wired connectivity.

Dallas – September 18, 2026 -- RSE, a European engineering and manufacturing company with more than 1.5 GW of realized and contracted energy projects, is entering the U.S. market targeting power generation and high-efficiency cooling and heating technologies for data centers and industrial clients.

RSE Energy LLC becomes authorized Olympian dealer for diesel and gas generator sets

RSE Energy LLC has secured status as an Authorized Sales and Service Provider for Olympian, within its authorized U.S. territory. The Olympian line, designed and manufactured by Caterpillar, spans 20 to 200 kW and supports standby, demand response and prime power applications. RSE will provide local engineering and technical support across the equipment lifecycle.

Södertälje, Sweden – September 17, 2026 -- Scania has launched Scania Dynamic, a comprehensive update to its R- and S-series trucks that cuts total energy consumption by around 2 percent while overhauling the driver's cab environment.

Aerodynamic redesign drives the efficiency gain

The 2 percent energy reduction, which varies by vehicle specification and operation, stems from exterior changes that lower air drag. These include digital rear-view mirrors, side skirt extensions, redesigned A-pillars, new door handles and a front end built to support Increased Vehicle Dimension legislation. Scania says the efficiency improvement applies across both combustion and battery-electric powertrains, translating into lower fuel use for diesel fleets and reduced electricity draw for electric trucks.

Berlin – September 15, 2026 -- Midea has sold more than 10 million R290-based air conditioning units globally since 2018, cutting an estimated 5.2 million tonnes of CO2 equivalent, the company announced at IFA 2026 in Berlin.

Midea claims 16 straight years as the world's top producer of R290-refrigerant air conditioners

The natural refrigerant carries near-zero global warming potential, contains no PFAS compounds, and delivers roughly 10% higher energy efficiency than conventional alternatives, according to the company. Midea says the carbon reduction achieved through R290 unit sales matches the absorption capacity of 6.2 million hectares of Amazon rainforest.

Berlin – September 15, 2026 -- Midea has sold more than 10 million air conditioners using the natural refrigerant R290 since 2018, cutting an estimated 5.2 million tonnes of CO2 equivalent emissions, the company said at IFA 2026 in Berlin.

Midea holds the top spot in R290 air conditioner production for a 16th consecutive year

The company positioned itself as the world's largest manufacturer of R290-based air conditioning units, citing the refrigerant's near-zero CO2 footprint, absence of PFAS chemicals, and roughly 10% higher energy efficiency compared with conventional alternatives. Midea said the emissions avoided through its R290 sales volume are comparable to the carbon absorption capacity of 6.2 million hectares of Amazon rainforest. A cutaway model at its booth let visitors view the compressor technology in operation.

Berlin – September 15, 2026 -- Midea has sold more than 10 million R290-refrigerant air conditioners globally since 2018, cutting carbon emissions by approximately 5.2 million tonnes of CO2 equivalent, an impact the company compares to the carbon absorption of 6.2 million hectares of Amazon rainforest. The Chinese appliance maker detailed its sustainable HVAC portfolio at IFA 2026 in Berlin, positioning R290 natural refrigerant technology as the centerpiece of its European growth strategy.
