Eco Racing

The idea of environmentally friendly motor racing at first glance seems like an oxymoron. Yet there are numerous examples of eco racing where speed isn't the only measure of success. And it's not just driving skills that are tested; most events require the manufacture of a vehicle - stretching engineering skills too.

Wind Turbine Powered Tricycle

What do you get if you combine a wind turbine with a tricycle? The Ventomobile - a vehicle that can drive directly into the wind, but is also powered by the wind.

Whales Inspire New Turbine Blades

Turbine blades inspired by whales (that's the mammals and not a misspelling of the country Wales) show promise in delivering improved efficiency and operational range. This example of reverse engineering of a naturally evolved design (referred to as biomimicry) demonstrates that nature is still a rich resource of inspiration for traditional engineering disciplines.

NASA is 50

It's fast approaching 50 years since US President Dwight D. Eisenhower and the US Congress created the National Aeronautics and Space Administration (NASA to its friends). October 1, 1958 marks the moment when the US started taking space seriously and the rest, as they say, is history - a glorious history.

Greenbird: World Land Yacht Speed Record Contender

Wind power, with its green credentials, is a primary force in our attempt to reduce our reliance on fossils fuels in order to reduce global warming. The majority of effort to exploit wind power is focused on converting its energy into electricity. However, if you are willing to live on the edge you'll find examples of wind energy used directly to power land-based vehicles, and very quickly in Greenbird's case - a world land yacht speed record contender.

Green Power in the City

Mayor Michael Bloomberg has proposed a bold green-power vision for New York. As a first step his administration has issued a formal request for proposals to exploit natural energy sources (wind, solar and water) to power the city.

General Aviation Technology Challenge

August is a busy month for competition fans, what with the Beijing Olympics just wrapping up, the US Open Tennis Championship about to start, numerous motor racing events, such as Formula 1 Grand Prix, and the 2008 General Aviation Technology (GAT) Challenge. OK, so maybe the GAT Challenge isn't quite in the same league as those other competitions, but with US$300,000 up for grabs, it's a serious competition intended to stimulate innovation in the personal air vehicle (PAV) arena.

Beijing 2008 Olympics: Sports Engineering

It's not only the stadiums at the Beijing 2008 Olympics that have received the attention of engineers wielding the latest Computer-Aided Engineering (CAE) analysis software - it's also the sports events themselves.

Beijing 2008 Olympics: Civil Engineering

Prior to the August 8 start date of the 2008 Olympics in Beijing, there was already evidence of outstanding performances; not from athletes (their turn will come), but instead from the army of engineers and architects responsible for the design and construction of the Olympic sports venues.
