What if your hour-long commute was reduced to just minutes? That's the promise of the hyperloop: a transit system designed around a pod that zooms through a vacuum-sealed space (roughly the size of a subway tunnel) at hyper-speed, powered by next-generation batteries and state-of-the-art magnetic levitation. In the visionary talk, Josh Giegel, the hyperloop's very first passenger, shares how this zipping innovation could launch us into a faster, cleaner future of transportation. Hosted on Acast.

Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80° Celsius, the Sahara Desert receives about 22 million terawatt hours of energy from the Sun every year. That's well over 100 times more energy than humanity consumes annually. So, could covering the desert with solar panels solve our energy problems? Dan Kwartler digs into the possibility. [Directed by Christoph Sarow, AIM Creative Studios, narrated by Jack Cutmore-Scott, music by André Aires]. Hosted on Acast. See acast.com/privacy for more information.
