Few ideas for getting from A to B have gripped popular imaginations in the modern era as strongly as the personal jet pack. The ultimate gravity- and traffic-defying machine has appeared in comic books, science fiction novels, Hollywood films, and circus side shows for decades.
The dream is alive and well today. This photo shows a flier strapped into a jet pack from Jetpack International over Denver, Colorado. The company makes three jet pack models, each weighing 180 pounds. One model, sold only to specially trained pilots, can fly for an estimated nine minutes or 11 miles (18 kilometers), up to 250 feet (76 meters) in the air.
Two other models, built for demo use only, run on hydrogen peroxide. The mild antiseptic and hair bleach can be used as a rocket propellant in concentrated form. (It doesn't burn but releases a great deal of energy when it decomposes in the presence of a catalyst.) But as an energy alternative, hydrogen peroxide has disadvantages, including the amount of energy required to produce it. And don't expect to go far in one of these demo jet packs; maximum flight time is less than a minute.
Would you buy one if they are being sold? Even though i assume the prices will be extremely expensive.
I probably wouldn't buy something that would only last me a few minutes. But I would definitely want to try it sometime if that ever were an option! Maybe rent one???
I wouldn't buy a jetpack, it'd be too expensive. Maybe I'd try it out of a friend had one but I'm scared of heights and something would probably go wrong
