| Summary |
Challenging the land speed record; the toxic depths of Sydney Harbour; recycling buildings; and crustacean love potion.LAND SPEED RECORDIn 1898 the land speed record stood at just 63 kilometres per hour. Today it's 1,223 km/h. Roscoe McGlashan wants to go even faster. Graham Phillips travels to Perth, at a somewhat slower pace, to kick the tyres of the jet powered vehicle Roscoe used in his 1996 record attempt, and checks out his latest dream machine - powered by a rocket! The rocket will carry two and a half tonnes of hydrogen peroxide that will provide the thrust that Roscoe believes will propel the car to its target speed of 1,600 kilometres an hour.GREEN BUILDINGSOver 40 percent of all waste produced in Australia comes from building construction and demolition. About 6 million tonnes of waste is sent to land fill each year. But what if we were to recycle buildings? Tanya Ha finds out what a life cycle analysis of a building is, and how a new type of greener cement is set to replace the traditional form of the most commonly used building material.TOXIC SEDIMENTSEnvironmental reform and the introduction of offshore sewage outlets have improved the quality of Australian waterways including Sydney Harbour. But, beneath the surface sparkle and shine lurks a dark menace that renders bottom feeding fish like mullet dangerous to eat. Mark Horstman reports on the deadly toxins that continue to enter Australia's most famous harbour - every day. CRAYFISH ATTRACTIONWhat do crustaceans put behind their ears to attract a mate? For crayfish the answer is as simple as taking a tinkle. Females illicit male mating behaviour by urinating, but the urine also provides a chemical signal to encourage aggressive behaviour. The female provokes fights with males to weed out the weaklings and ensure that only the strongest males will sire her progeny |
