South Australia launches sweeping residential energy storage program

Rooftop solar is now providing up to 45 per cent of generation at certain times of the day, and the growing amounts of solar could push that grid demand to zero in coming years, causing AEMO to look for ways to try and “orchestrate” this resource for the overall benefit of the grid.The scheme could add up to 400MWh of storage to the grid – not quite four times the size of the 100MW/129MWh Tesla big battery next to the Hornsdale wind farm that has dominated interest from operators and market players – and this could time shift the output of solar, and provide essential grid services.More: South Australia opens biggest household battery storage support schemelast_img read more

What lies in the famous Egyptian pyramids?

first_imgAs the technology develops to see behind walls, we may be about to discover hidden wonders in the pyramids of Egypt, secret chambers, concealed passageways and, as it turns out, ‘hot’ stones! Infrared thermography has revealed a fascinating ‘anomaly’ at Giza.The Egyptian Ministry of Antiquities has announced the preliminary results of its ScanPyramids project. They suggest an anomaly in the Great Pyramid of Khufu, which could unfold some ancient secrets.Through infrared thermography and non-invasive cosmic rays, the two-week research found three ‘hot’ stones on the eastern side of the Khufu pyramid in Giza, one of the largest pyramids in Egypt and over 4,500 years old.Archaeologists are of course a thirst to know the reason behind these thermal differences.last_img read more
