Widespread adoption of electric cars in New South Wales would increase demand on the power grid by an average of eight per cent, according to new research from the School of Engineering.
Sohaib Rafique and Professor Graham Town used data from the New South Wales Household Travel Survey to determine the demand that electric cars would place on the grid if they were used in 82 per cent of weekday and 81 per cent of weekend commutes, with trips less than 35km in length.

A new approach to horticultural spraying could be the result of a collaboration between design students from Kyoto Institute of Technology and Swinburne University in Melbourne.
“Yanmar is a manufacturer of farm machinery, and they asked us to solve a big problem for grape-growers,” says Natsumi Takamatsu, a design student at Kyoto.
“What we developed was a sprayer to mitigate the drift of sprayed agricultural chemicals. Really it was the actual viticulturists when we interviewed them and they were saying things like ‘If only I had something like this.’”
“Australia and Japan enjoy the seasons at opposite times of the year so we can conduct field research in the vineyards all year,” says Yoshiro Ono from Kyoto Institute of Technology.
Harnessing the sun and improving agriculture
Mitsubishi Heavy Industries have built a pilot concentrated solar power plant in Yokohama. It uses CSIRO technology now being manufactured by South Australian company Heliostat SA.
“We’re making seven-and-a-half-metre square solar mirrors,” says David Linder-Patton, the CEO of Heliostat SA.
They focus the sun’s energy into a tower receiver that generates heat which can be used in industries such as steel manufacturing, brick processing and mineral refining.
The Mitsubishi plant will test their technology on receivers they have developed and also CSIRO’s suntracking technology and heliostat manufacturing.
“Working with companies the size of Mitsubishi helps us to get to industrial scale a lot quicker than we could do otherwise,” says David.
Over sixty-five million Indonesians live off the grid. But what does that mean in the era of micro-grids, batteries and efficient solar panels? And how do communities change with 24/7 energy?
Providing reliable electric power is one of the keys to unlocking the potential of the remote islands and landlocked areas of Indonesia and of Australia’s north, a priority for both countries.
But there’s much more to it than installing the right mix of technologies. Bringing night-time activity, television, the internet and smart machines within the reach of people who have never had access to them before involves huge, potentially disruptive changes to their daily lives, their economic and political relationships, their whole culture.
A team of Australian and Indonesian scientists and social scientists is coming to grips with the scope of the problem by studying two sites in Indonesia where a start has already been made on introducing electricity. The seed project is financed by the Australia Indonesia Centre.
