While we're still waiting for our jet pack
and saving up for our Moller Skycar
, it looks like we may soon have another flying machine at our disposal once the Skyacht personal blimp hits the market. The blimp's been in development since 2002 (including some makeshift wind tunnel testing) but just recently underwent its first tethered test flights and is set to make its first untethered flight later this month. Unlike traditional blimps, the Skyacht simply uses hot air instead of helium, and employs a "virtually silent" motor for propulsion. The use of hot air makes the Skyacht cheaper to operate than other blimps but, as you can see, also requires a much bigger balloon. Rest assured though, it is the world's first "practical" personal blimp.
