Formula E's Futuristic Sound Puts F1 to Shame

A lot of people are not happy with the sound of the new engines in this year’s Formula One. As a result of extensive rule changes, the 2014 F1 cars are much quieter than last year’s models, with none of that ear-splitting high-pitched scream that made 2013–and earlier–cars so appealing. And now, a competitor is putting them to shame. Read More >>

Scientists Built an Impossibly-Small Engine, But Don't Know How it Works

It must be fun to invent something. One day it does not exist, and the next day it does exist. But how would you feel if you didn't exactly know why your new invention worked? The minds behind this all-new microscopic engine could tell you. Read More >>

Why Engines are Commonly Measured in Horsepower

>We owe this unit of engine power measurement to Scottish engineer James Watt. Read More >>

Pure Space Porn: These are the Naughtiest Rocket Parts

Rocket hardware is always awesome eye candy, no matter what country is sending stuff into space. Awesome, and, well, sexy. You know what I mean. I like the rockets with the boom. Just look at all these pretty space-bound asses. Read More >>

You Can Cradle This Three-Cylinder Engine Like an 40-Kilo, 400 HP Baby

An engine this small should, by conventional logic, not be this powerful. But, somehow, it is. And at this year's 24 Hours of Le Mans, Nissan plans to see just how well its under-sized, over-powered hybrid engine prototype handles F1's most gruelling challenge. Read More >>

GM's RFID Engine Bolts Prevent Assembly Line Screw-Ups

hreaded fasteners haven't changed drastically since they were invented ages ago. But now, General Motors has put RFID tags in the bolts used on engine assembly lines, turning simple hardware into tracking devices that make sure everything gets assembled properly. That bolt's got a (2kb) brain! Read More >>

It's Not Broken, The Open Rotor Turbine is Supposed to Look Like That

This is not a broken turboprop engine. It's a new radical aircraft engine design by French engine manufacturer Snecma, one that will forgo the traditional bypass system and remove the engine ducting altogether while reducing fuel consumption, greenhouse gas emissions, and engine noise.

The Next F-35 Lightning's Engine Adapts for Flight, Fight, and Beyond

Unlike commercial airliners, modern military aircraft are subjected to ever-changing flying conditions—from high-thrust takeoffs to flying at altitude to combat maneuvers. So why are they outfitted with engines that perform optimally in only one of those flight envelopes? For the next iteration of the F-35 Lightning II, Pratt and Whitney is developing an engine that performs at its best no matter what's required of it. Read More >>

NASA Successfully Test-Fires a Rocket Engine Built With 3D Printed Parts

While current real-world applications of 3D printers are usually quite depressing tales of nerds spending £3,000 to be able to print out a replacement chess piece, things are moving quickly up at the high-end sector of the market, with NASA claiming success in 3D printing spare rocket engine bits.

Bad News: 2014's F1 Cars Are Going to Sound Rubbish

The FIA's decided to get with the program of fuel efficiency and is forcing every F1 team to swap their beastly and incredibly-high-revving 2.4L V8s for smaller 1.6L V6s with turbos. On the face of it, that's better for our normal-car tech development, but what it means is they're going to end up sounding a bit crap. Like vacuum-cleaner whiny. Rubbish. Read More >>

Watching a Porsche Engine Get Torn Apart Is Truly Mesmerising

I can't stop watching this stunning timelapse. The sheer number of parts that go into even a relatively old performance engine is simply mindboggling. How a mechanic can take them apart, then rebuild them from scratch, I have no idea. Such incredible engineering displayed so beautifully. [YouTube via Jalopnik] Read More >>

NASA's Next Rocket Engine Could Be A Blast From the Past

Jeff Bezos isn't the only person interested in vintage NASA technology. Public and private entities alike are actively taking a second look at the Rocketdyne F-1 engines that helped notch Saturn V rockets as the tallest, heaviest, and most powerful rocket ever operated—even today, forty years after the demise of the Apollo program.

The World's Biggest Jet Engine Is Brawnier Than Alan Shepard's Orbital Rocket

The Wright Flyer took off in 1903 powered by a measly 12 horsepower straight-four. Little did Orville and Wilbur know that just 110 years later, their pokey engines would eventually lead to a power plant with more horsepower than the Titanic and Shepard's Mercury-Redstone 3—combined. Read More >>

Skyflash, the Personal Jetpack That Needs a Runway and a Death Wish

Skyflash is a German DIY invention that involves strapping a wing and a pair of rockets to man and seeing if it all flies. And, as today's latest test video shows, it does. Only at an altitude of a few inches, but it's a good start. Read More >>

US Warships Could Soon Run on Detonated Waves

Every one of the modern US Navy's 129 ships, and its entire fleet of aircraft, relies on gas turbines for either basic propulsion or to generate electricity for their critical systems—typically both. But as fuel costs continue to rise, these turbines now burn through nearly $2 billion of fuel annually. That's why the Naval Research Lab is developing a revolutionary new type of engine that could reduce our armada's energy consumption by as much as 25 percent (and save $400 million a year) even as the Navy transitions to "all electric" propulsion systems.

We Are So Close to Inventing a Real-Life Mr. Fusion

Some would argue that the biggest obstacle robotics currently faces isn't the Uncanny Valley or suppressing the urge to destroy all humans — it's keeping their batteries charged. The newest version of the EcoBot may have the answer — it eats poop. Our poop. Read More >>
