What it is:
A jet pack is the convenient apparatus that you wear on the back in order to permit short-range flight. There is a dissimilarity around a jet pack, a rocket pack and a rocket belt, but essentially, all of them work on the same theory. Just in case you wondered, Jet engines present two openings (an intake and an exhaust nozzle), while a rocket only has 1.
A jetpack, of any kind, is likely to be driven by jets of escaping gas.
There are many private airborne devices that do actually work, but the jet pack, despite the general silliness of that notion, still captures the imaginations of writers, inventors and adventurers the world over. So much so, that despite many (many) conceptual setbacks presented with the theory, working ‘rocket belts’ have actually been created (and used) for some time now. This is a fact that makes me unspeakably merry.
Why we want it:
Because being able to fly can be ridiculously splendid, as would having the ability to soar effortlessly over the demanding streets, traffic jams and cars screaming out crappy music twenty four hours a day.
A trip to the shops can be so friggin’ grand that the common jet pack-owning household would most likely make enough shopping trips to single-handedly save the financial system. Or something.
When can we expect it?
Jet packs are unsafe (most want huge quantities of tremendously flammable Hydrogen Peroxide in order to work). They’re also overly expensive (Hydrogen Peroxide doesn’t come cheap) and insanely risky as well as being (I’m sorry to say) completely and absolutely illogical as the mode of transportation.
Having said that, Eric Scott piloted the ‘Go Fast Sports’ Rocket Belt in San Carlos, CA in 2008, the flight was a short one, but impressive nonetheless. Similar demonstrations of rocket packs/belts may be seen via a quick trip to Youtube. All the flights are short and wildly anarchic, but all of them appear to be a lot of fun.
So, when do I need my very own jet pack?
A few years ago, a rumour circulated that it was possible to build a completely functioning jet pack from objects available about the Internet. It is not (and you’d be foolish to even try). Sadly, true jet packs, the kind seen in science fiction serials as a secure, inexpensive, dependable means of personal transport, remain within the domain of sci fi, a place where they’ll probable stay evermore.
Will the jet pack ever become a bona-fide means of transportation for the general public? No. Never, but it is nonetheless fun to fantasize.
Cool Factor: 5/5
Jet packs? Come on, there is zero more grand than that, certainly?
