The design looked to me like a load of those vibrating poles but mounted on a raised track. But it seems that the blades actually travel around the track.
The claims about costs seem insanely generous, but I do appreciate that making it easier to move the parts of a conventional HAWT is reall tricky, plus the heavy equipment and cranes for assembly.
But .......... I'm not convinced, till we hear/see these operating economically.

Craziest Ever Wind Turbine Is Not So Crazy After All
If you’re on the lookout for crazy looking wind turbines, look no farther. At this stage of development, the Airloom concept looks more like a rather aggressive clothesline rather than a device for harvesting wind energy.
Instead of mounting massive blades on gigantic turbine towers, the Airloom device consists of 10-meter wings that travel along a lightweight track, supported by a series of poles that are only 25 meters high. Depending on the desired scale, the track can range in length from meters to miles. The height of the track can also vary.
The low-profile arrangement runs counter to the trend of wind turbines that reach high into skies with longer blades to capture the most efficient wind resources. However, depending on the landscape, local wind conditions, and neighbors, a more modest silhouette could open up a wide range of new sites where conventional turbines are either impractical or restricted by local laws.
Here’s What Airloom Says
Bizarre-looking it may be, but Airloom’s test-scale device was enough to convince Breakthrough and other investors. The cash infusion will enable Airloom to scale up from the current development phase of 50 kilowatts, leading to megawatt-scale devices and full deployment in wind farms where megawatts are counted by the hundreds.
If all goes according to plan, Airloom calculates that its wind farms can be built for less than 25% of the cost to build a conventional wind project. That may seem over-ambitious, but the company estimates that its device costs less than 10% of the cost of comparable wind turbines.
