Can someone explain to me why wind turbine blades do not have an abrasion resistant leading edge (other than allowing them to slowly erode, BY DESIGN, in order to profit from the monumental maintenance costs)???

@wearetherace @HillF1 @SportmphMark It's not the first time it has happened. Newey often goes to extremes, especially in regards to packaging. But historically, he tends to overcome setbacks. These setbacks seem to be greater than usual, but I would bet on him and the team overcoming them for 2027, if not earlier.

Did Adrian Newey’s design request doom Honda? 😳 @HillF1 and @SportmphMark discuss why projects from F1’s greatest technical mind either end in triumph or disaster on the latest episode of The Undercut.

@battlefieldexpl It's a shame to see it in that color, but the exterior seems in quite good condition.

This Panther belonged to Panzer Brigade 107, one of the units that made Market Garden's ground advance a nightmare. It fought around the Peel Marshes and was knocked out near Overloon. It never left. It's now in the Overloon War Museum which should be on everybody's bucket list.

@alexboge I think that the relative position of the sun also changed. That alone can influence several variables.

From the very same people who demanded to see stars in photos… now come complaints about the photo that shows these stars. 🙄 Let’s walk through what you’re actually looking at. These two images were taken less than a minute apart from Orion during Artemis II, using a Nikon D5 with a 14–24mm f/2.8 lens. The EXIF data is publicly available. This is not speculation. The image on the left is essentially what the scene looks like to the eye. The image on the right uses the full capability of a modern sensor, with higher ISO, longer exposure, and a wider aperture to pull in far more light. That is why you can clearly see the stars. (ISO basically is simply the camera’s sensitivity to light.) Nothing was added. Nothing was “photoshopped.” These are two direct captures showing what happens when you change settings with a capable camera. Now here’s why this matters. For decades, one of the loudest talking points from Moon landing deniers has been: “Where are the stars in the Apollo photos?” Apollo did not use modern digital cameras. They used modified Hasselblad film cameras with low-ISO film, about ASA 64 for color and ASA 80 for black and white, chosen specifically for photographing bright, sunlit lunar surfaces. That choice was intentional. Those cameras were designed to be simple, reliable, and usable with gloved hands. Limited settings. Low light sensitivity (ISO). Built and setup for the lighting conditions they knew they would encounter. And that comes with a tradeoff. When you expose correctly for a bright foreground, faint stars do not register. There was no practical way, with that equipment, to capture both a properly exposed lunar scene and faint background stars in the same shot. What these Artemis II Orion images demonstrate, very clearly, is exactly that principle, using a modern DSLR camera. One setting → no stars Another setting → stars appear Same place. Same moment. Same reality. The only thing that changed was the camera settings. And now that the answer is literally being shown to them, the question somehow remains, because like all zombie conspiracies, the goal is not understanding and seeking the truth, it is keeping the dead conspiracy alive.

@CuriosityonX The relative position of the sun changed, the camera changed, and Apollo 17 took place in December. Those are significant changes. I would not draw any conclusions based on these images alone.

@somersetlurcher @ScarbsTech The split between ICE and battery was changed in favor of the ICE, and energy deployment was reduced (at least for quali). But it's not enough. A single, additional generator, on the front axle, would recover A LOT more energy. There's no need for 2 generators on either end.

@Lva_Sc @ScarbsTech I thought they already limited the amount of power harvested to help reduce clipping. I may be wrong but I don't think splitting collection between front and rear would reduce it as you need to spin the charge systems. Would two smaller collectors slow cars less than one big one?

@ScarbsTech What's your opinion on F1 and the FIA allowing energy recovery from the front axle as well, for 2028 or even 2027? Would there be space for it, packaging-wise? Allowing for more recovery could help reduce clipping, I think. Many thanks.

@SfameniSteve @OnDisasters @F111Driver I apologize. "Propaganda" was way too harsh of a word. Sometimes it gets frustrating seeing so many errors by so many people in regards to military/political topics. We are only human. I make plenty of mistakes myself. I sincerely apologize. I wish you a wonderful day as well.

The F-15 Eagle´s unprecedented record of over 100 kills and zero losses (despite fake mullah claims) is, in part, due to its outstanding speed and agility. The F-15's high thrust-to-weight ratio and low wing loading enable it to achieve superior maneuverability and acceleration. And that is exactly what this video demonstrates: look at it go up like a high-speed elevator!

Formula 1 has prepared 6 measures for the meeting that will take place next week, in order to solve the issues saw in the first 3 race - Increse the power of super clipping (frmo 250kW to 350kW) - Reduce energy consumption so that it does not run out so quickly - Reduce the maximum recharge per lap to 6MJ - Unrestricted use of active aerodynamics, meaning it can be activated at any point on the circuit - Increase the ICE/MGU-K ratio (at the earliest from 2027 onwards) - Simplify the rules to give the drivers more control 📰 @wearetherace

@RBRHub This idea of, effectively, punishing those who did a good job doesn't sound very appealing. RBPT and Audi at least have the argument of being new manufacturers. That fine. That makes sense. Ferrari and Honda do not. They played by the same regulations as Mercedes PU's division.

🚨 Laurent Mekies: We expect to be among the group that receives ADUO. Laurent Mekies was asked about the possible updates from ADUO, but first addressed the problems at Red Bull - "Regarding the critical aspects: we don't think there is one specific area where there are shortcomings. We think it is across the board. It's the chassis, the power unit — it's everything." "It is difficult to assess your performance relative to the competition, especially in the game of energy deployment and such. But to answer your question as directly as possible: we think Mercedes is clearly ahead. And since they are clearly ahead, we expect to be part of the group that receives ADUO."

もしもいすゞがF1に参戦していたらどうなっていたのか?自社の技術確認用に作られたガソリンエンジンをF1マシンに載せてテストした記録があるんですが、その結果が凄いんです。なんとアイルトン・セナのマクラーレン・ホンダと比べて差はわずか5〜6秒だった。もし本気で開発していたらと思ってしまう。

@elonmusk Cares so much about space exploration and moon missions that he hasn't posted a single tweet about Artemis II's mission. I'd bet that he's secretly hoping that the mission fails so he can continue to transport bananas to the Indian Ocean in that stainless steel flop.

@RealAirPower1 They have some similarities, but I wouldn't say that they are very similar in configuration. Once you look closely, they are quite different.

The MiG-29 is very similar in size and configuration to the F/A-18C/D Hornet. With its massive leading-edge strakes, canted twin fins, and those raw Klimov RD-33 engines, the Fulcrum was built for the high-alpha knife fight. This said, its short legs and basic early avionics often held it back from being the true multi-role powerhouse. Now, as it reaches the twilight of its career, do you think the MiG-29 actually lived up to its full potential, or was it always just a "point-defense" sprinter playing a marathon runner's game?

@CoreyLewis86 The weight distribution should be somewhere around 90/10. If he brakes too hard, the rear wheels will probably leave the tarmac.
