Power to the regions, I say!
A new solar power plant is going to be built with the help of some funding by the state government.
Like other solar thermal systems, this new plant with a 1.5MW (initially) turbine generator located in the town of Morawa is capable of providing energy on demand, and around the clock. It does this by placing a solar receiver containing a quantity of graphite on a 24 metre high tower and surrounding it with a number of toroidal heliostats which follow the path of the sun and direct its rays onto the receiver where water is super-heated up to 800 deg C (1472 deg F).
After passing through the turbine, the steam is then condensed to water and re-circulated into the feedwater system – a feature that, along with its use of air-cooled condensers – makes the Solastor System ideally suited to arid regions, with limited water supplies.
The system is also modular, with each receiver and its surrounding array of toroidal heliostats making up a single module (and approximately 4 modules per hectare of land) (For American readers: 1 hectare = 107 639.104 square feet, or approximately 2.5 acres).
Nice and compact, isn't it?
