Contemporary Challenges Facing Our Planet

1 global warming by 2100: Intensifying humanitarian emergencies with more frequent and severe heatwaves, wildfires, floods, tropical storms, and hurricanes.

1 people live in climate-vulnerable areas, with regions having weak health systems—mostly in developing countries—least able to prepare and respond without external support.

1 people lack electricity access, and 1 depend on polluting stoves and fuels for cooking, causing harmful indoor air pollution and health risks.

1 people lack safe drinking water, causing 1 diarrhoeal deaths annually from diseases like diarrhoea, cholera, dysentery, typhoid, and polio.

4 Transformative Technological Innovations

Passive Radiative Cooling Coating

Developed by Prof. Edwin Tso, this technology uses local waste materials to reduce house temperatures by up to 30°C, enhancing thermal comfort without the need for electricity.

Applications: Community housing, rural schools, health clinics, temporary shelters.

Impact: Improved thermal comfort, reduced carbon emissions, and local community empowerment.

Affordable Printable Solar Films

Developed by Prof. Alex Jen and Prof. Angus Yip, these scalable perovskite solar cells provide affordable electricity for rural areas.

Applications: Rural homes, schools, health outposts, water pumps.

Impact: Access to electricity, clean cooking, irrigation support.

Biomass Waste-to-Energy

Developed by Prof. Charles Xu and Prof. Carol Lin, this technology converts biomass and plastic waste into biofuels, promoting circular economies.

Applications: Urban slums, agricultural villages, remote towns.

Impact: Sustainable waste management, reduced reliance on fossil fuels.

Human-Powered Sanitation System

Developed by Prof. Zhiguo Yuan, this electricity-free UV disinfection system uses triboelectric generators to provide safe, potable water.

Applications: Remote villages, disaster zones.

Impact: Improved access to clean water, reduced incidence of waterborne illnesses.
