A new concept design in electronics cooling exploits ionic wind, or, more formally, a corona discharge, to improve the efficiency of traditional cooling fans. The same effect is also able to propel a levitation device called an ionocraft, and was also incorporated in an air purifier.

Since the Wright brothers' first 12-second flight in 1903 we've seen impressive development of flying machines, from the helicopter to the Space Shuttle. However, a small, personal jetpack has proved both enticing and elusive.

The remote controlled X-48B concept airplane flew for the first time on July 20, 2007. Joining an illustrious list of previous X-planes, such as the X-15, the X-48B aims to prove the viability of the blended wing-body concept – a combination of a flying wing and a lifting body. If history is anything to go by, the X-48B will have its work cut out.

Who hasn't wondered at those magical curve balls that we see in sports such as tennis, soccer, baseball and most impressively in ping pong? Or been disappointed by a horrible slice in a game of golf? Of course, there is no magic, these are just examples of aerodynamics in action – the Magnus effect to be precise.

The new Scuderi Split-Cycle engine design concept promises increased efficiency and reduced harmful NOx emissions compared to the current generation of internal combustion engines found in most cars. Ironically, this new concept is a variation on the notoriously inefficient and polluting 2-stroke engine.

The wind turbine is the poster child for extracting energy from our environment. However, there are numerous other devices that range from the mundane, such as hydroelectric dams, to the downright scary, such as the Atmospheric Vortex Engine which is another word for a controlled (?!) tornado.
