How to Cool the Planet by Capturing Contrails | Dr Sarah Qureshi | TEDxFaisalabad Medical University
Perhaps more than carbon emissions, the streaks that plague our skies are contributing to global warming?
In order to prevent global warming and provide a new source of onboard water, Dr. Sarah Qureshi, Pakistan's leading aerospace innovator, reveals a ground-breaking solution: engine-side technology that absorbs contrails, or those lingering white lines behind aircraft, and transforms them into stored liquid. Her vision? Clean skies, a cooler climate, and even rainfall on demand.In this talk, you’ll discover:Why contrails contribute more to global warming than aviation’s carbon dioxide alone—accounting for up to 50–60% of aviation’s climate impactHow her patented technology condenses water vapor inside aircraft engines to eliminate persistent contrails at source, drastically cutting aviation’s hidden warming effects
A compelling financial and environmental case for retrofitting existing planes—scalable, low-cost, and globally impactfulA bold mission for Pakistan: to showcase global leadership in green aviation and contribute to environmental solutions from Lahore to the world"We aim to make skies blue again—one aircraft at a time."
Leading a climate technology movement based on local creativity and global responsibility, Dr. Qureshi is turning research into practical action.Dr. Sara Qureshi, PhD in Aerospace Propulsion from Cranfield and a licensed pilot, is co-founder of Aero Engine Craft, Pakistan’s first aero-engine R&D company. She invented a contrail-free engine system with major climate benefits and is among the few women globally to invent a supersonic jet engine. With 33 international awards and a passion for green aviation, she’s redefining sustainable tech. A true trailblazer for women in aerospace, Dr. Qureshi was honoured with the Tamgha‑i‑Imtiaz in 2025 for her groundbreaking contributions. *We rise by lifting others.* This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

- 10:47Pixels and Perspectives: Finding Meaning in the Details | Daniyal Harris | TEDxIBAWhat if the smallest, most overlooked moments in your life held the key to who you're meant to become? In this talk, Daniyal Haris explores how life’s tiniest “pixels”—the hardships, rejections, and quiet victories—can come together to form a meaningful picture. Drawing from his journey as a filmmaker and student, Daniyal argues that it's not about fitting into someone else’s frame—it's about building your own image, one pixel at a time. This talk is a reminder that no one else defines your potential, and sometimes, the clearest perspective comes from the blurriest beginnings. [Filmmaker - Storyteller]An IBA student with a filmmaker's soul, Daniyal Harris crafts stories that blur the line between memory and magic. His nostalgic style of filmmaking doesn't just tell a story - it transports you into it.
