Self-dusting solar panels
Self-cleaning technology developed for lunar and Mars missions could be used to keep terrestrial solar panels dust free. Dust deposits can reduce the efficiency of electricity generating solar panels by as much as 80%. The self cleaning technology can repel dust when sensors detect concentrations on the panel's surface have reached a critical level.

The completed stations are now saving 242 tonnes of CO2 per year - enough to fill the Sydney Opera House five times over.

As the inventor of a low-cost solar cell, he wants to help the world avoid an energy crisis by harnessing the power of the Sun. His translucent Grätzel cells use a combination of titanium dioxide and organic dyes to convert sunlight into electricity, providing a cheaper and more environmentally friendly source of energy than silicon solar cells.

Micropower environmental energy harvesting generators offer an alternative source of renewable energy. These power supplies can help to support environmental, wearable or surgically implantable microsystems. They can assist or even replace batteries in some applications.

However, according to a report from Companies And Markets, Australia is now considered to be one of the world leaders in a technology to play a critical role in addressing how the world utilises energy in the future - smart grid development.

The scheme became national in 2000 and by then there were 15 products from 14 electricity companies and almost 57,000 customers. Most of the "green" electrons were from "biomass" sources, such as landfills with rotting organic matter, which produce methane that can be captured and used to generate electricity. Wind and solar power were miniscule but interestingly, solar was installed on the rooftops of the Sydney Olympic Village at Newington.

A total of 32 new green projects will receive funding under the Climate Ready program, spanning everything from wind turbine production for renewable energy and tree planting projects for carbon pollution reduction, to carbon neutral biofuel processors and waste management and processing technology.
