Jet pack - In the same bracket as flying cars - Superflous

Consumer Jetpacks Will Be Flying By 2016, Martin Aircraft Says, But First You Need $150K 

The first flight of the Martin Jetback, shown here in 2008, reminded observers of science fiction fantasies popularized in the 1950s and 1960s.

The jetpacks have finally arrived. Decades after science fiction writers first popularized the idea of strapping a rocket to your back and piloting yourself through the air, a New Zealand aircraft company has announced it will actually start selling commercial jetpacks for a price of $150,000. But consumers will need to wait until 2016.

Built by the Martin Aircraft Company, the jetpack (known as the Martin Jetpack) would be the first aircraft of its kind to go on sale to the public. Rather than being powered by rockets, though, the jetpack lifts off and navigates with help from large fans, which are easier to control. It's capable of carrying a 260 pound person 1,000 meters into the air before they deploy a parachute, company sources told Reuters.

Even with such a high cost, Martin suggested jetpacks will be more than a toy for millionaires. They say the aircraft can safely land on wire-laden rooftops and navigate tight areas, two advantages over a helicopter.
