Have you heard of this approach to generating energy? Its not solar panels. There are photos at the site that make the process clearer.

A solar concentration system:

Features of the National Solar Energy Centre

The NSEC is the only multi-collector facility of its type in Australia and home to the largest high concentration solar array in the Southern Hemisphere. At peak operation it generates enough energy to power more than 100 homes.

The NSEC consists of three main elements:

• A high concentration tower solar array that uses 200 mirrors to generate more than 500kW of energy. It will be capable of achieving peak temperatures of over 1000°C;

• A low concentration linear solar array that generates a hot fluid at temperatures around 250°C; and

• A control room facility that will house the centre's communications and control systems and serve as an elevated viewing platform.

The NSEC is used to research and demonstrate advances in innovative solar technologies in collaboration with other national and international research institutes. The solar concentrators will initially be used to develop two technologies.

The low concentration array will be used to provide thermal energy that drives a small, high-speed turbine designed for use in remote power applications and distributed generation markets. This will produce not only electricity but heating, cooling/chilling and desalination. Thermal storage will be used to overcome the issues of transient sunlight.

The high concentration array will be used to provide the temperatures needed to produce a solar gas that contains over 25 percent more energy than the natural gas feeding into the process. This solar gas can then be processed to solar hydrogen. Solar gas and solar hydrogen provide all the benefits of solar energy but with all the convenience of gas. It enables solar energy to be stored and transported. The technology serves as a transitional route toward higher levels of solar penetration into the energy mix.

CSIRO Energy Technology and the Energy Transformed Flagship will use the NSEC to promote collaboration through shared use of the facility by Australian and international researchers.

This project is proudly supported by the International Science Linkages programme established under the Australian Government's innovation statement Backing Australia's Ability, as well as the NSW Government's Sustainable Energy Research & Development Fund (SERDF).
