CSIRO's solar technology has been exported to Japan in a move that further demonstrates the viability of solar as an international trade industry for Australia.

Mitsubishi Hitachi Power Systems (MHPS), which received funding from the Japanese Ministry of the Environment to "develop and verify technologies for enhancing measures to reduce carbon dioxide emissions", will establish a field of 150 heliostats in Yokohama to run research projects.

The project is also a welcome boost to the car industry, with the CSIRO-designed heliostats being constructed by a South Australian manufacturing company actively coping with the downturn in the automotive industry.
