Researchers at Ghent University have hit on a method of harvesting energy from raw sewage that treats the wastewater without using external electricity. It's all thanks to starving bacteria. Although this method is still in its lab testing stage, industry leaders are already interested in utilising it.

It took "one of the most significant severe thunderstorm outbreaks in recent decades", with seven tornadoes and a storm producing phenomenally damaging wind speeds, to bring down South Australia's power grid and cause a blackout in late September. Although the national electricity market operator and conservative commentators were quick to blame renewable energy, it's now clear that the entire network was at risk -- and the blackout could have been lessened had precautionary steps been taken.
