Prime Minister Julia Gillard last week used the example of Spain to indicate how Australia’s energy mix could be transformed. The potential for this transformation is nothing more than wishful thinking…
Fracking. It’s a hotbed of controversy that spans our increasingly energy-hungry globe. The French have turned their back on it. Permanently. And now the NSW government has temporarily frozen the use of…
The Earth energy balance – the difference between energy/heat absorbed by the Earth from solar radiation and the energy/heat emitted back to space – is currently offset by the cooling effect of sulphur…
Scientists have created a glucose-powered biofuel cell that is five to 10 times more powerful than existing cells and lasts weeks longer, paving the way for implanted medical devices that run on the body’s…
That tangled collection of chargers could one day be obsolete, as Australian researchers report a breakthrough that brings us closer to a world where gadgets are recharged every time you press them. Scientists…
