Haken: Passive Kühlung entfeuchtet nicht. Luftfeuchtigkeit muss raus, sonst greift die Taupunktsteuerung ein & erhöht die Vorlauftemp. Folge: geringere Kühlleistung (kleineres ΔT). Stosslüften am Morgen ist Pflicht.
Fazit: Perfekte System-Integration, günstig im Betrieb! 🏡🥶

Kühlung scheint gerade DAS Thema auf X zu sein. 🥵
Wärmepumpe erfolgreich mit passiver Kühlung (Freecooling) nachgerüstet. Ergebnis: Haus bleibt bei Hitze unter 23°C. Grosser Vorteil: Gratis Kälte aus dem Boden, keine hässlichen Split-Geräte & minimaler Stromverbrauch! 🧵

Das System nutzt den Unterlagsboden nachts als Kältespeicher, tagsüber kaum Aufwärmung. Leistung trackt ein Belimo Energiezähler (via Modbus). Ausbeute zuletzt: ~20 kWh Kühlleistung bei nur 1 kWh Strom für die Umwälzpumpe! 🤯📉

Yesterday, two Boeing E/A-18G Growlers collided mid-air during an airshow demonstration at Mountain Home AFB, Idaho.

All four pilots successfully ejected using the Martin-Baker US14A (NACES) Ejection Seat.

The German Dornier Do 31 was the world's only jet-powered VTOL transport. Immensely complex, it was built with 2 Rolls-Royce Pegasus vectored engines + 8 Rolls-Royce RB162 lift engines. First flew in 1967, wowed at 1969 Paris Air Show, canceled in 1970 because it was TOO cool.😎

Yes... In case anyone was wondering, Microsoft still sucks in space.

Together with RDW, we have officially completed the final vehicle testing phase for Full Self-Driving (Supervised) and have submitted all documentation required for the UN R-171 approval + Article 39 exemptions. The RDW team is now reviewing the documentation and test results package internally. They have communicated the expected approval for Netherlands date of 4/10, shifting from 3/20 previously and we look forward to successful completion of this cooperation. 

Following the Netherlands’ approval, European countries will be able to recognize this approval nationally. We are anticipating a possible EU-wide approval during the summer.

Over the past 18 months, this approval has involved a series of intense documentation, development, testing, research & audits. Including but certainly not limited to:

– 1,600,000+ km of FSD (Supervised) testing on EU roads
– 13,000+ customer sales ride-alongs
– 4,500+ track test scenario executions
– Thousands of pages of written documentation for 400+ compliance requirements
– Dozens of research studies into safety performance/results

We're extremely proud of the work conducted with the RDW team up until this point.

We very much look forward to the approval in April, and sharing FSD (Supervised) with our patient EU customers!

Fourth pass through Melissa this morning, another side view due to my hairbrained attempt to shoot 8k video out the front.

[Tropical Cowboy of Danger @FlynonymousWX]

Third pass through Melissa. GoPro in side window as different camera looking forward shooting in ultra high res 8k. Not sure when that might get processed as the file turned out ridiculous. Barely had HD space for it and MacBook Pro promptly chocked when I tried to edit it

No surprises here for anyone. Inadequate. That covers it. Sadly.

Power duo 🤝 Our brand-new Airbus A350 on its way home to Zurich, was met in the skies by an extraordinary sight: jets from the Swiss Air Force joining in formation. 🇨🇭
A proud welcome to the newest member of our fleet. ✈️
