‘I see myself as a royal’: artist Vincent Namatjira on colonialism, satire and his great-grandfather’s legacy The image of his great-grandfather has loomed large in the work he has created since 2012 – from the 13-panel series Albert’s Story in 2014 to a 2023 portrait that formed part of his Desert Songs series – but Vincent has never sought to imitate the recognisable style of his ancestor. “We have both had to fill our legacies,” he says. “I want the audience to see my work and my name, Vincent Namatjira, with the work of modern art – more portraits, figurative. It’s colourful and bold.” Namatjira’s 2018 series Legends features land rights campaigner Eddie Mabo, football player Nicky Winmar, songwriter Archie Roach and artist Gordon Bennett. Photograph: Vincent Namatjira/Iwantja Arts, This Is No Fantasy Many of Vincent’s portraits pay affectionate tribute to his heroes, including his artist father-in-law, Kunmanara (Jimmy) Pompey, Archie Roach, Nicky Winmar and Eddie Koiki Mabo.

‘I see myself as a royal’: artist Vincent Namatjira on colonialism, satire and his great-grandfather’s legacy To show our tradition and culture, and art – also to show the rest of the world that Indigenous people, we need to be heard. A few decades after winning that classroom prize with his sketch of the Endeavour, Vincent’s success means that for many younger audiences, the name “Namatjira” brings to mind his name, not Albert’s. “They tried to do what Albert Namatjira left them, that kind of technique with watercolour painting,” he says of his great-grandfather’s legacy. “To be honest, I’d like my family and my culture and tradition to change their ways, and go forth and broaden the name. “To choose. He chose his own path. Well, I choose mine.” Vincent Namatjira: Australia in Colour opens on 20 October at the Art Gallery of South Australia before touring nationally. Desert Songs is showing until 28 October at Yavuz Gallery in Surry Hills, Sydney. Vincent Namatjira (Thames & Hudson) is out now.

A new hydrogel could help pull drinking water from the air This is another in our series of stories identifying new technologies and actions that can slow climate change, reduce its impacts or help communities cope with a rapidly changing world. We all need clean water to survive. Yet across the planet, more than one in every four people live in places without enough. And climate change is making this worse. Now scientists have created a new salty gel. It sucks record-breaking amounts of moisture out of the air to make fresh drinking water — even in dry climates. Carlos Díaz-Marín is a mechanical engineer at the Massachusetts Institute of Technology (MIT) in Cambridge. His team is developing a device to address water shortages. They want it to affordably pull water from air without a need for electricity. The key ingredient: a new, super-salty gel. A hydrogel is a mesh of large molecules called polymers. The new hydrogel captures humidity — water vapor — from the air. As it does so, it expands like a sponge in water.

A new hydrogel could help pull drinking water from the air There was a problem signing you up. More food, less water Earth’s freshwater supply is falling due to climate change. By 2050, more than five billion people are expected to lack water at least one month per year. Some shortages are due to warmer temperatures and less snow to feed into rivers. That puts stress on supplies of water for drinking and growing crops. Whatever the cause, better water-slurping gels could make it easier to grow food in such water-stressed places — including those plagued by drought. Tan’s team has developed a gel-based device called the SmartFarm. This tiny greenhouse with a moving roof grows crops without having to add water. In the evening, the top opens. Gels inside capture water from the night air. A solar-powered motor closes the roof during the day. When warmed by the sun, the gel releases its water. Tan’s team used the SmartFarm to grow a leafy green vegetable called Ipomoea aquatica.

Bringing aqueous rechargeable zinc iodine batteries to the mainstream energy market New research aims to improve the stability and safety of alternatives to rechargeable lithium-ion batteries using aqueous zinc and hydrogels. The demand for rechargeable batteries as a result of the growth of both the personal electronics and electric vehicle markets has grown steadily over the last decade. Lithium-ion batteries are one of the technologies that have emerged and matured due to this demand. In 2020, Statista estimated that lithium-ion batteries accounted for 185 gigawatts (GWh) of energy consumed, and this energy demand is projected to reach 2,035 GWh by 2030. Most of this growth is accounted for by the increased desire for electric vehicles as people turn away from fossil fuels. While it is undeniable that lithium-ion batteries are more environmentally friendly than fossil fuels and while they are also relatively inexpensive, these batteries aren’t perfect.
