Australian company Enviromission was recently on the Discovery Channel discussing their proposed solar tower in central NSW. Enviromission is run by Paul Davey who has been passionately pursuing the concept of a massive solar tower for power generation in NSW since 2001.
They are well underway on the project, nearing completion of the final feasibility phase prior to commencing construction.
Generally speaking the project is massive, truly massive. The central tower will be 600m high, taller than the tallest building on earth and will generate enough power for 100,000 homes.
The principle utilises natural convection created by the massive area of glass across the ground, creating hot air that will be drawn towards and up through the central tower driving 32 turbines that generate the power.
