Ongi Etorri!! Libertarian; anti war and anti censorhip. Pro neutrality; supporter for a reasonable change to sustainable energy.



Battery storage is soaking up low-cost renewable power while displacing higher-cost coal and gas power when it discharges that power back to the grid. It is no surprise that it is growing extremely quickly. Learn more: hubs.li/Q04fdGLP0





Europa hat ein Industriecluster für Großwärmepumpen – und riskiert es gerade durch politische Wankelmütigkeit. Die Hersteller der größten Anlagen sitzen in Berlin, Oberhausen, Österreich und der Schweiz. Aber wenn die Förderung wegbricht, kommen die Pumpen in zehn Jahren aus China. cleantech.ing/p/die-w-rmewen…



Primeur! Vandaag hebben we onze nieuwe volledig elektrische Fendt in gebruik genomen! ⚡️🚜



Washington has warned European allies, including the UK, Poland, Lithuania and Estonia, to expect long delivery delays for US weapons — including Nasms and Himars — as it scrambles to replenish stockpiles depleted by the Iran war. Deliveries to Ukriane have already been delayed. w/ @FT colleagues ft.com/content/f87a8b…


VW ID.Polo: 36.040€. Kleinwagen. ca. 453 km Reichweite. Tesla Model 3: 36.990€. Mittelklasse-Limousine. 534 km. Fast gleicher Preis. Komplett anderes Auto. Das muss doch ein Fehler in der Matrix sein, oder? 🤔

A massive display panel has been installed on one of the Bank of China buildings, creating a stunning visual effect.


















You cannot buy a new gas turbine until 2030. Order books at GE, Siemens, and Mitsubishi stretch to 2029. Turbine prices have nearly tripled since 2019. Every AI data center needs power and every gas plant needs a turbine. And every turbine has one part that bottlenecks the entire industry: The blade. It has to survive in gas 500°C above the melting point of the metal it's made from and spin at up to 20,000 RPM under 10,000 g of centrifugal force. Each blade is grown as a single crystal of nickel superalloy, pulled through a vacuum furnace at 3 mm per minute. A set of blades costs $600,000 and takes 90 weeks to grow. The same metallurgy powers modern jet engines. Only 3 companies on Earth can build one. China spent $42 billion trying to catch up. They bought a Russian fighter engine, took it apart, and copied every part. Their copy ran 30 hours between overhauls versus 400 for the original. Modern Western engines run 4,000. You can reverse engineer the shape of a turbine blade. You cannot reverse engineer 60 years of metallurgy.
