The car is expected to go on sale in the US next year but both left and right-hand drive models have been designed, meaning it could be adapted for use in Australia.

Also yesterday came a suggestion from a General Motor's strategist that Australia should be looking at alternative energy sources, such as solar and biofuel, to power cars of the future.

About the same time several large Australian corporations announced an interest in building the world's largest solar thermal energy plant.

These stories illustrate changing attitudes and opportunities when it comes to energy production and personal transport.

When big business wants to get on board a renewable energy future, clearly it is a future they see as profitable.

Their involvement is seen as a precursor to funding to build the power plant, multiple versions of which it is claimed could produce half of Australia's 2020 renewable energy target.

For the many Australians keen to see a reduced reliance on coal-fired power stations, this is an encouraging prospect.

Ballarat and Australia all wish Libby well

IN 2004 Libby Lenton entered the Athens Olympic Games as a favourite in the 100m freestyle.

In that year she had set a world record in that event, although the record did not stand for long before it was eclipsed by fellow Australian Jodie Henry.

In Athens Lenton was unexpectedly eliminated from the 100m freestyle in a semi-final.

Four years later, married and now known as Libby Trickett, she has already claimed gold in the 100m butterfly at Beijing.

And today the 100m freestyle heats begin and Trickett will have a chance to overcome the disappointment of Athens.

On recent form there is every chance the beaming Queenslander will be able to demonstrate that the four years have only made her more determined to succeed.

It will be a remarkable tale of perseverance if she can add another individual gold to her trophy cabinet and many Australians will be willing her to do well.
