TED-Ed: How do jetpacks work? And why don't we all have them? | Richard Browning

The video explores the evolution of flight technology, comparing the ease of launching a massive spacecraft to the challenges of creating a functional jetpack. It delves into the physics of flight, explaining how jet engines work and why larger engines are more efficient. The video highlights the difficulties engineers faced in designing jetpacks, such as limited fuel capacity and control issues. However, advancements in materials and computing have led to the development of micro engines and the innovative jet suit by Richard Browning. Despite these advancements, personal jetpacks remain a distant possibility without further improvements in fuel efficiency and engine technology.
