We owe this unit of engine power measurement to Scottish engineer James Watt. In the early 1780s, after making a vastly superior steam engine to the then classic Newcomen steam engine, Watt was looking for a way to market his invention, advertising the fact that his engine used about 75 per cent less fuel than a similarly powered Newcomen, among many other improvements.

Threaded 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!
Unlike commercial airliners, modern military aircraft are subjected to ever-changing flying conditions — from high-thrust takeoffs to flying at altitude to combat manoeuvres. 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.
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.
Boeing's 787 Dreamliner and Airbus' A380 are both competing to replace an ageing fleet of 747s that have served passengers for more than 40 years. But what's to be done with all those jumbo jets once they're been replaced? MotoArt has the answer, at least when it comes to the 747's gigantic engines: a stylish conference table that looks suitable for a meeting of the world's most evil supervillains.
When it comes to make LEGO engines, it's hard to beat Rolls Royce's 152,000-piece Trent 1000, but the doesn't mean we should give up entirely. In fact, we should follow the example of YouTube user "Solde1" and his plastic V16 4AGE engine.
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, 40 years after the demise of the Apollo program.
Even though today's largest aeroplane engines are capable of producing more than 45,000kg of thrust, they are still susceptible to ice build-up in the sub-zero temperatures at cruising altitude. To ensure the next generation of mega-engines can withstand the worst that Old Man Winter can throw at them, GE has set up a testing centre in the coldest, most inhospitable frozen environment this side of Hoth — Winnipeg, Canada.
The 109,000 HP Wärtsilä-Sulzer RTA96-C diesel engine is the largest and most powerful, but at 2000 tonnes, any warship it's attached to is going to have trouble outmanoeuvring jellyfish, much less torpedoes.
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 $US2 billion of fuel annually.
That's why the US Naval Research Lab is developing a revolutionary new type of engine that could reduce our armada's energy consumption by as much as 25 per cent (and save $US400 million a year) even as the navy transitions to "all electric" propulsion systems.
Conventional natural gas turbines suffer from a hefty performance tradeoff: they can either burn fewer BTUs per hour, or they can rapidly adjust their output to meet changing energy demands. The new FlexEfficiency gas turbine from GE, however, promises to do both while making renewable energy even cheaper.
The 152,455-piece Lego Rolls-Royce Trent engine may be the most complex Lego machine ever built, but it's nothing compared to the real thing. This awe-inspiring time-lapse video shows how they built the turbo-fan engine that powers some of the most popular airliners in the world, including the Boeing 787 Dreamliner.
