Lennox’s new extreme cold heat pump operates at as low as -20F

Image
Image: Lennox Lennox Residential HVAC has launched an extreme cold climate heat pump that warms a house with low global warming potential (GWP) refrigerant in temperatures as low as -20F. It’s called the  Dave Lennox Signature® Collection SL22KLV Cold Climate Heat Pump , and Lennox claims its efficiency levels are 150% higher at colder temperatures than standard heat pumps. In 2022, Lennox was the first company to complete the first phase of the US Department of Energy’s (DOE) Residential Cold Climate Heat Pump (CCHP) Technology Challenge, and the SL22KLV is a souped up version of the unit developed for that challenge. The heat pump, which pairs with a smart thermostat, uses a variable-speed compressor with Electronic Refrigerant Injection (ERI) to adjust the energy usage based on the outside temperature, which helps to lower energy costs. When the temperature drops, the ERI increases heating output efficiently.

Musk denies that U.S. will drop Starlink support for Ukraine over minerals

Image
By Zachary Visconti Posted on February 23, 2025 Following a report that the U.S. government may be threatening to turn off SpaceX’s Starlink satellite internet in Ukraine unless the country agrees to a minerals deal, Elon Musk has responded by saying that the reports aren’t true. On Saturday, a Reuters report cited three unnamed sources that claimed U.S. negotiators had brought up the possibility of turning off Starlink in Ukraine, after President Volodymyr Zelenskiy rejected a proposal earlier this month from U.S. Treasury Secretary Scott Bessent. Starlink has played a crucial role for the military staying connected in the embattled country, and sources alleged that the officials were told in a meeting that the services could face an imminent shutoff. “Ukraine runs on Starlink,” one source said. “They consider it their North Star. Losing Starlink … would be a massive blow.” In a post on X on Saturday following the report, Musk denied the claims, sayin...

Image
By Zachary Visconti Posted on February 22, 2025 Tesla and CEO Elon Musk have doubled down on plans to deploy in-house robotaxi ride-hailing services, as highlighted in a recent conversation with Uber’s top executive. Uber CEO Dara Khosrowshahi says that Musk was not interested in talking about utilizing the Uber platform for Tesla’s future robotaxis, as detailed in a recent report from Fortune .

GSA, which manages all federal government-owned buildings, also operates the federal buildings’ EV chargers. Federally owned EVs and federal employee-owned personal EVs are charged on those 8,000 charging ports. The Verge reports it’s been told by a source that plans will be officially announced internally next week, and it’s seen an email that GSA has already sent to regional offices about the plans: “As GSA has worked to align with the current administration, we have received direction that all GSA-owned charging stations are not mission-critical.” The GSA is working on the timing of canceling current network contracts that keep the EV chargers operational. Once those contracts are canceled, the stations will be taken out of service and “turned off at...
