Nuclear fusion future

Visit the world's largest nuclear fusion reactor, which uses the same process as the Sun to produce energy. Look at the new advances in fusion technology which mean, for the first time, a fusion reactor should now be able to produce more energy than it consumes. It offers a future alternative energy source, but is not without ...

Hydrogen-diesel engine

How might we reduce damaging emissions from diesel engines and increase their fuel efficiency at the same time? Watch as Dr Vishi Karri from the University of Tasmania describes the development of a new type of engine: the hybrid hydrogen-diesel engine. Dr Hafez A Hafez explains how the technology can be easily adapted ...

Hydrogen and its properties

Imagine the possibilities if we could turn the most abundant element in the universe into a source of fuel. Watch as the Surfing Scientist, Ruben Meerman, investigates the properties of hydrogen and then demonstrates its potential as a fuel when he sets fire to hydrogen-filled soap bubbles.

Radio image of the Circinus Galaxy, 2002

This is a false-colour velocity field image of the neutral hydrogen gas in the Circinus Galaxy. It was composed from data collected by the Australia Telescope Compact Array, located at the Paul Wild Observatory near Narrabri in New South Wales. Different colours represent different speeds. Red areas are moving away from ...

Hydrogen void in our galaxy, 2002

This is a false-colour image of warm atomic hydrogen gas in the outer Milky Way Galaxy made with the Australia Telescope Compact Array at Narrabri and the Parkes radio telescope. The gas is shown as bright yellow and orange in colour and there is a large void in the centre of the image indicating that hydrogen is absent ...

Large Magellanic Cloud, 2002

This is a false-colour image of the Large Magellanic Cloud made with the Australia Telescope Compact Array at Narrabri and the Parkes radio telescope. It shows clouds of atomic hydrogen which appear to be swirling in a circular motion.

Water molecule

This is a colour image of a model of a molecule of water, H₂O. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The water molecule contains one oxygen atom (the red sphere) and two hydrogen atoms (the grey-white spheres).

Structures and Bonding

This simulation allows students to explore the chemical reactions between hydrogen, oxygen, carbon, nitrogen and chlorine. They can form water, carbon dioxide, hydrochloric acid, ammonia and methane. Word and chemical equations are provided. The diagrams distinguish single, double and triple bonds and shapes of molecules.
