A perfect espresso is more a function of science than art - contrary to many people's experience. The majority of the processes required to turn green coffee beans into a delicious espresso is dominated by fluid dynamics.

Using a Stirling engine (which converts heat into useful work) for electronics cooling seems like a perfect fit - at least according to Micro-Star International (MSI). In retrospect you wonder why no one thought of the concept sooner.

What do you get if you cross a reel lawn mower with an airplane? The answer is FanWing - a low-speed airplane concept. Unlike a traditional fixed-wing airplane, the FanWing can generate lift independent of its forward airspeed. The source of its lift is a cross flow fan resembling the cylindrical blade on a reel lawn mower.

Anyone well versed in aerodynamics knows that Computational Fluid Dynamics (CFD) is an indispensable analysis tool - just ask the automotive industry. However, CFD, like all analysis methods, has limitations. For example, try calculating the unsteady air flow around an entire Formula One (F1) car in less than a week. Fear not though; help may be at hand in the form of a new experimental analysis method using a Wind Funnel.

In the near future it's likely that airplane pilots will not actually venture into the air. Most 'pilots' will instead 'fly' Unmanned Aerial Vehicles (UAVs) from ground-based virtual cockpits. This trend is already evident in the military, but it is poised to extend to and transform all branches of piloted aerospace vehicles.

Combining a car and an airplane into a single vehicle has proved to be an elusive dream. The convenience of a so-called flying car goes unquestioned, but the technical challenges are immense. It seems that the flying car is eternally 5-10 years away from reality. Each of the latest crop of would-be flying car manufacturers thinks that they have the necessary secret sauce to bring the flying car to life.

Inspired by the (fictional - yes, it was a scaled model) underwater Lotus Espirit that James Bond drove in the movie "The Spy Who Loved Me," Frank Rinderknecht of Rinspeed commissioned ESORO to build the sQuba, a concept car for the Geneva Motor Show. What's so special about the sQuba? It can really 'fly' underwater.

I've noticed a flurry of announcements that cite the use of Computational Fluid Dynamics (CFD) in the design of new cars for public roads and race tracks. While none of these announcements say that CFD was responsible for the design of the whole car, equally they don't say, with much clarity, what exactly did CFD contribute?
