We're not sure what's going on here, but we're not going to complain: Blimps are making a comeback. There are powerful hauling blimps, sure, but BAE is hopping on the autonomous systems bandwagon with its nimble GA22. The 22-meter (72 feet) dirigible is meant to carry high-tech surveillance equipment weighing up to 330 pounds at an altitude around 6,500 feet. The unmanned craft could also be used for sporting events, floods, and forest fires, says BAE. Right now the vehicle is radio-controlled but the ultimate release will be completely autonomous. Unfortunately, this means we can't take a ride, but, as we said, it's still a blimp, and blimps are just straight-up cool.

We love dirigibles and we're not about to apologize for it, so that's why Boeing's new Skyhook JHL-40 airship has us ooh'ing and aah'ing in wonder. The eight-engine blimp is being developed for 40-ton 200-mile hauls in adverse environments such as wildernesses and what Boeing calls places "no other kind of transport can go." It is also slated to have a minimal impact on the environment with a carbon-minimal footprint as it won't require new roadways in remote areas. Of the eight engines, four provide lift while the other four control direction. Two production prototypes are under development at its Rotorcraft Systems facility in Ridley Park, PA. Can we sign up for a test flight? Maybe? Just a little?

It's not everyday we see innovations in blimp technology, but a team of researchers at the Swiss Federal Laboratories for Materials Testing and Research are keeping the helium-filled dream alive, developing a blimp that effectively swims through the air like a fish. According to New Scientist, that's done with the aid of some artificial "muscles" that expand and contract when given a jolt of electricity, allowing the vehicle to wiggle its way through the air, cutting down on the noise in the process. While it can currently only stay aloft for 20 minutes at a time, the team thinks the technology could eventually see a wide range of uses, including sending airships far up into the stratosphere, possibly as platforms for wireless communication. From the looks of it, however, it seems like we could be seeing the blimp in toy form well before that happens -- at least we hope so.

Although it's not exactly shocking to hear of yet another homeland security application that seems to border on Big Brother, Lockheed Martin's High Altitude Airship could keep an elevated eye on 600 miles of US countryside at any given time, and if all goes as planned, we'll have 11 of these things floating over our everyday activities by the end of the decade. The HAA prototype is a ginormous airship that measures 17-times larger than the Goodyear rendition we're all used to seeing above sporting events, and is designed to hover 12 miles above the earth in order to keep tabs on what's happening below. The airship is slated to be solar-powered and should stay in a geocentric orbit for "up to a year," and if equipped with high-resolution cameras, a single one could cover everything "between Toledo, Ohio and New York City." While Lockheed Martin is thrilled with the $40 million project they've been awarded, it's certainly understandable to get a little worried about how these blimps will actually be used, but a company spokesperson suggested then an entire fleet could actually be used for "border surveillance" -- and hey, we need a little help down there anyway, right?

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.
