UNSW's Engineering the Future

Using renewable energy such as wind and solar to create environmentally friendly electricity is great - but what can we do to replace the use of fossil fuels in industrial sectors that can't easily be electrified? 

This can include heavy manufacturing, aviation, maritime transport, and chemical production. These industries need high-density energy or specialised fuels and processes that electricity alone cannot provide efficiently. 

That's where green fuels come in. In this episode of Engineering the Future, UNSW lecturer Dr Emma Lovell and industry expert Constantine Tsounis, join STEMM journalist Neil Martin to explain how they are made and why they are so important. 

They discuss the process of turning renewable resources into biofuels, green hydrogen, biogas, and synthetic fuels to help drive the reduction of greenhouse gas emissions - making decarbonisation possible for even the hardest-to-abate sectors.

PFAS—also known as "forever chemicals"—are in your water, your clothes, your food packaging, and even in your body. 

They’ve been widely used for decades to make products resistant to heat, stains, grease, and water, including non-stick cookware, firefighting foam, and stain-resistant fabrics. 

But engineers, regulators, and the public are increasingly concerned about their long-term impact.  

In this episode of Engineering the Future, environmental engineers, UNSW Professor Denis O’Carroll and Andrew Mitchell from ADE Consulting, joins STEMM journalist Neil Martin to unpack the science behind PFAS and how they ended up in our environment.  

They explain the new detection and removal methods used to clean up PFAS, and emphasise the need for better regulation, public awareness, and the development of better alternatives of the chemical.

Not all healthcare is created equal. 

Whether it’s a postcode that limits your services, a language barrier at the clinic, or a system that overlooks accessibility - too many people are being left behind. But how do we build healthcare systems that can fairly serve its communities regardless of postcode, income, or identity? 

In this episode of the Engineering the Future podcast, UNSW’s biomedical engineer Associate Professor Lauren Kark, and Managing Director of Taking Paediatrics Abroad, Kathryn Currow, chats with STEM journalist Neil Martin, about the challenges of ensuring healthcare that is just for all and the importance of advocating for sustainable solutions and capacity building over mere financial investment.

Cybersecurity threats are growing more sophisticated every day, making the protection of personal and corporate data more critical than ever. As artificial intelligence reshapes both attack methods and defence strategies, what are the risks of not securing our infrastructure against emerging threats?

Lecturer at UNSW School of Computer Science and Engineering and former NASA researcher, Dr. Hammond Pearce, and Director of InTune AI, Sharat Madanapalli, joins STEMM journalist Neil Martin to unravel the evolving landscape of cybersecurity and how to safeguard your privacy online.

From smart homes and cities to business and healthcare, smart technology is promising to enhance efficiency, convenience, and connectivity in daily life. But with it comes growing concerns about data security, reduced privacy, and the control of information.

Dr Sebastian Sequoiah-Grayson, Senior Lecturer in Epistemics at UNSW's School of Computer Science and Engineering, and senior experience strategist Dr Erika Whillas join STEMM journalist, Neil Martin, to discuss how smart technology will change the way we live and interact with our communities in the future - and how best to deal with the challenges it will undoubtedly create.

Too much water in the form of flooding, or too little water in the form of drought. Two of the biggest global challenges when it comes to water are at completely opposite ends of the spectrum.

They discuss the importance of ensuring the ever-increasing global population has safe water to drink, and enough water to also grow suitable amounts of food, while also dealing with issues around flooding and sea

Industrial decarbonisation is a fundamental way Australia and other countries around the world can achieve 'Net Zero' emissions targets by 2050, and therefore fulfil promises made in the Paris Agreement to help reduce climate change.

David Eyre, CEO of the UNSW Institute for Industrial Decarbonisation, and engineering and manufacturing executive Shay Chalmers join STEMM journalist Neil Martin to talk about the challenges of decarbonisation as populations grow and demand for products such as cement, steel, plastic and ammonia rise as a result.

They will explain why fostering collaborations and partnerships is important to keep producing such important materials while also reducing greenhouse gas emissions, and provide analysis about new decarbonisation technologies, revealing how technical and economic feasibility is just one part of the whole process.

Supersonic commercial planes are making a comeback, but it may be only high flyers that can afford them.

For everyone else, our cities could soon drastically change as flying cars (but not as we imagine them) are set to extend the reach of our cities and slash commute times.

UNSW senior lecturer in aerospace design, Dr Sonya Brown, and sustainable aircraft designer Andrew Moore join STEMM journalist Neil Martin to talk about the future of flight. They also debunk myths about hydrogen fuel dating back to the Hindenburg blimp disaster, discuss the use of drones to save lives by fighting bushfires, and explain the tricky balancing act needed to make flying more sustainable.

800 million people currently go to sleep hungry, but 1 in 4 of us are predicted to be obese by 2035. Securing access to food for everyone and making it sustainable for our planet are some of our greatest challenges. Professor Johannes le Coutre, the leader of UNSW’s food program, and Katherine Samaras, Laboratory Head of the Garvan Institute and specialising in diabetes and obesity prevention, join STEMM journalist Neil Martin to talk about potential solutions for keeping us fed and the planet happy. They discuss why looking back to old agricultural techniques could hold some answers, and how diabetes drug Ozempic isn’t the fix for over-eating. 

UNSW researchers are largely responsible for the way the world uses solar power today. Decades of innovation on photovoltaic cells from people at this very university have helped the world get a running start on the global green energy transition. But there’s more work to be done. A lot more. 

Executive Director for the Australian Centre for Advanced Photovoltaics, Professor Renate Egan, and Vice-President of world-leading solar module manufacturer JA Solar, Dr Zi Ouyang, join STEMM journalist Neil Martin to discuss how the industry is making leaps and bounds, what’s happening with old rooftop panels and the potential for covering houses in solar cell ‘paint’.
