How did SpaceX film inside a 33-Engine Raptor inferno without the camera melting? 🚀🔥 What looks like a camera melting inside a massive explosion is actually a masterclass in extreme aerospace engineering: SpaceX capturing close-up footage of its 33-Engine Raptor ring firing simultaneously. Instead of relying on standard commercial camera housings that would vaporize instantly, this setup uses heavy-duty, customized protective enclosures engineered to withstand thousands of degrees of intense heat and vibrational stress. Paired with optical-grade sapphire crystal viewports and active cooling systems, the lens remains entirely uncompromised as the engine cluster ignites into a blinding wall of fire. At a time when deep-space exploration requires pushed technical boundaries, this unbelievable footage proves that capturing the heart of a rocket blast no longer requires sacrificing the gear. Simply put: Bringing highly specialized thermal shielding to a high-speed camera setup marks a massive evolution in aerospace diagnostic engineering and launch documentation.

BMW M5, E60. This is what made it special. The engine. V10 in a family saloon, what was BMW thinking or snorting back then? 500 hp from the S85B50 V10 engine, high revving and one of the best sounding V10's ever and the best sounding BMW of all time. Nothing else matters as much. Of course, there are downsides. Reliability isn’t great. This is not a simple car to own. But that’s part of it, high risk, high reward. You take care of it, and it gives you that V10 sound. Some even converted them to manual to ditch the SMG gearbox and USA even got the manual from factory. And there’s a Touring as well, even more added insanity.

Shell in the Spotlight Again as More Motorists Blame Contaminated Fuel Sold at Their Stations for Engine Damage Fuel service stations operated under the Shell brand, which is managed by Vivo Energy Kenya, are once again on the spot after another frustrated motorist blamed poor-quality fuel for allegedly damaging his car engine. The incident reportedly happened just moments after the driver refueled at Shell Links Road in Mombasa when the vehicle began losing power on the way to Voi. Despite pushing forward, the problem worsened, and the car eventually stalled a few kilometres before Kitui, forcing the motorist to seek emergency mechanical assistance. A mechanic from Kitui ran a diagnostic test and found severe engine damage, including a completely worn-out piston, citing contaminated fuel as the likely cause of the problem. With no alternative, the motorist had the vehicle towed back to Mombasa and reported the matter to Vivo Energy Kenya. A representative from the company requested a fuel sample for testing at their laboratory. On Tuesday, they informed her that the sample had passed all tests. The motorist, dissatisfied with Vivo Energy’s response, instructed his mechanic to conduct a more thorough inspection of the engine to determine the extent of the damage. Upon dismantling the engine, the mechanic once again confirmed that one piston was completely worn out, an issue he attributed to contaminated fuel. According to the mechanic, the level of damage was consistent with prolonged exposure to poor-quality fuel, suggesting that the problem began soon after refueling. The motorist, convinced that bad fuel was responsible, claims to have gathered video evidence showing the fuel sample in a mixed and compromised state. She insists that the sample, which was taken directly from her vehicle, appeared discoloured and inconsistent with what is expected of high-grade V-Power petrol. Despite presenting this evidence, Vivo Energy reportedly maintained that their tests found no issues with the fuel. The motorist is now escalating the matter, determined to hold Vivo Energy accountable for the damage. She has shared video evidence, showing the contaminated fuel and is calling for independent testing to verify its quality. Frustrated by what she sees as the company’s unwillingness to take responsibility, she is considering legal action and has reached out to consumer rights groups for support. This case adds to growing complaints from Kenyan motorists about fuel quality, with recent independent tests exposing major discrepancies in octane levels at several stations. An automotive content creator Kim JH of Tanuki Garage recently went around Nairobi, purchasing fuel samples from different stations and conducting on-the-spot octane tests. The findings revealed that some premium fuels, including Shell V-Power, underperformed compared to standard fuels. For instance, Total Limuru Road recorded the highest performance with a PON of 92, while Shell V-Power scored lower, challenging the common perception of premium fuel superiority. His findings, shared widely on social media, sparked outrage, with motorists demanding accountability from fuel retailers. Following the viral exposé, oil marketers, including Vivo Energy rushed to dismiss the findings, arguing that independent tests lacked credibility and did not follow industry-approved procedures. Shell Kenya, through Vivo Energy, insisted that its fuel met regulatory standards, pointing to tests conducted by the Energy and Petroleum Regulatory Authority (EPRA). However, the issue has refused to die down as more motorists continue to report unusual engine problems after refueling from previously reputable stations. Meanwhile, consumer advocacy groups have joined the debate, urging EPRA to conduct random and independent fuel quality tests at petrol stations across the country. They argue that the current reliance on oil marketers’ internal tests is inadequate and fails to protect motorists from potentially damaging fuel. The controversy has also drawn the attention of lawmakers, with some calling for stricter oversight and stiffer penalties for companies found selling substandard fuel. For motorists like the one affected at Shell Links Road, the issue is not just about technical standards but about accountability and compensation for the damage suffered. "Hi Nyakundi. I am Here to seek your intervention I fueled at shell links road ,vpower on Saturday, by the time I reached voi my car lost power I kept going but got worse as I moved. A few kms before kitui,the car stalled...I called a mechanic from kitui who came with a diagnosis machine and from what he said,I had put bad fuel. I towed the car back to msa. I reported to vivo. A guy from vivo by the name Brian mbaabu called and asked me to take the fuel for tests in their lab. He then called yesterday, on Tues and said that the sample passed all tests.... I asked my mechanic to open up the engine and to our surprise one piston is totally worn out an indication of bad fuel I will attach all I have including videos as I got the sample and it's all mixed up"

In 1909, the Gnome Omega became the first mass-produced rotary engine, marking a major step forward in early aviation. At a time when aircraft struggled with heavy, overheating powerplants, the Gnome Omega introduced a radical solution: the cylinders and engine block rotated around a fixed crankshaft, improving cooling and reducing weight. This unusual design allowed air to flow directly over the spinning cylinders, eliminating the need for bulky radiators. The high power-to-weight ratio made it ideal for pioneering aircraft, including those used by Louis Blériot during his historic 1909 crossing of the English Channel. Although rotary engines were eventually replaced by more efficient designs, the Gnome Omega remains a symbol of the experimental ingenuity that defined the birth of powered flight.

This video shows a static fire test of the Archimedes rocket engine, developed by Rocket Lab. Archimedes uses liquid methane (LCH.) as fuel and liquid oxygen (LOX) as the oxidizer, a combination known as methalox. During combustion, these cryogenic propellants produce extremely high temperatures (over 3,000°C), hotter than lava. To survive this, the engine circulates cold fuel through its walls before burning it, a technique called regenerative cooling. Multiple Archimedes engines will power Rocket Lab's upcoming Neutron rocket, which is being built to launch satellites and cargo to orbit with lower cost and higher reliability. Rocket Lab is best known for its Electron rocket and is now expanding into larger, reusable launch vehicles with Neutron.
