While the use of lethal militarydrones is a controversial subject, I give you the lifesaving promise of urban medical drones.
According to a USA Today investigation, up to a 76,000 of the 250,000 fatal heart attacks that happened outside of American hospitals every year were treatable. In this vision of our first responder future, those trained in first aid can sign up for an app that accesses a network of defibrillator-equipped drones parked atop tall buildings across the city. When someone needs help, they send a request through the app and an unmanned vehicle swoops down (0:35), bypassing any potential congested traffic to assist immediately.
It might seem far-fetched, but the drone technology already exists today. Spread the word so we can make this happen; your arteries will thank you.
