How close are scientists to developing a personal flying Device that would replace cars?
Imagine a Backpack with a propeller. No Car is necessary to Reach the Other Side of the City. You Can look into anyone's Window, no matter what Floor a person lives on. There will be new Traffic rules, fewer cars, fewer traffic accidents. How close are we to developing a personal flying device?
Currently, that technology is still far away. We have created jetpacks, but the amount of Fuel that they can Carry limits flying Time to about 30 seconds, and are Very expensive. However, a new scientific breakthrough will be needed to provide sufficient Power to Lift a person, as Well as sustain the person in the Air for an acceptable amount of time.
It will Come, One Day. Perhaps in 100 years, or even in 20 years. The first plane the Wright Brothers flew was Only in the air for 12 seconds, but now, 100 years later, airplanes Cross the Globe effortlessly Carrying hundreds of passengers and flying at High speeds for Many Hours. The same Case happened with trains, phones, computers, and soon, space travel.
Currently, MOLLER (www.moller.Com) is developing a flying car that could just be the forerunner of Your dream. First, Giant aircraft, then Compact flying cars, and finally, personal flying devices.
Another possibility would be that technology would develop in a Way that a personal flying device would Not be necessary. Teleportation may be developed, or an Ultra fast internet Service would Make travel obsolete, as there would be no need for it. The only problem would be obesity, as people would Walk Less, and get heavier.
The future awaits...
