The design does make sense but I do see some potential drawbacks. First off the pressure shelves are obviously spring loaded (similar to a paper napkin dispenser) and springs can break or get worn out from use and what good is such a system when the spring breaks thousands of miles from your destination. Secondly, I doubt airlines are going to want to install a special track into the aisle for these carts (although I do think that it's an interesting way to deal with the turbulence in flight). and a motorized cart just seems lazy. I think that the motorized elements plus the sunken track will likely result in additional weight over traditional carts. A thinner cart makes absolute sense as the current designs really have a lot wasted space and are not designed for the way many airlines do inflight service these days plus take up space not just in the aisle during service, but also space in the galley. The basic design could most certainly work as a wheeled cart, but some of the other elements may be a bit more than what an airline would be willing to do. If these cart could reduce the size of airplane galleys on an a/c or reduce the number of galleys needs on an a/c, airlines could potentially add more seats to maximum revenue on flights.

While it is smaller, it really will not work. Your typical narrowbody has an aisle width of ~20" (obviously depends on the seating). Considering this is 8" wide, that leaves you with only ~12" to play. Put it in the middle as shown and that is only 6" a side, not enough for someone (especially a larger person) to comfortably slip by without making things real awkward for the person sitting in the aisle seat. You could move the cart over to one side, but you are still only realistically looking at 10-11" of space, which is still a tight squeeze.
Considering all the additional costs for this idea is it really worth it? I'd say no.

With such a tall, narrow and (presumably) heavy cart, the first thing that comes to my mind is the incredible torque that will be imposed on the track about the plane's longitudinal axis. Those things would have to be pretty strong.
But yes - as Polot said, it doesn't really seem like this will solve the problem of getting around the cart in the aisle. There's just not enough clearance.

Interesting concept and design but may only be suitable for aircraft operating short haul. It would certainly appeal to LCCs offering BOB of the takeaway type. But on an 11 hour flight where meals typically include fruit, salad, bread roll, a hot main course, cheese and biscuits, a cup of water and/or juice, the meals would not fit into the small box required.
From a cabin crew point of view, it appears more ergonomic in serving meals and would reduce strains caused by kneeling up and down placing trays into a cart. But how does it perform with reloading all the used boxes and waste after the meals service?
The track would not only provide stability during turbulence but would prevent the cart being tipped as a (dreadful euphemism alert) person of size attempts to squeeze past. Eight inches width is quite a small foot print, especially as in the diagram the cart would appear to be longer than the standard carts in use. As meals were unloaded the cart may become top heavy, increasing instability. If the cart is longer, how much space would actually be saved?

Why not just make a conventional cart about half the width, and keep the design, well, conventional? I know it would be prone to tipping over outside the confines of an aircraft aisle, but at least in the aisle if it tips, it would be stabilized by the seats...
