Because turbines aren't commonplace and traditionally require rigorous inspections and maintenance. Which wouldn't fit with the idea behind light sport aircraft (strong focus on simplicity for recreational pilots).
Seth, it may not be impossible to design something stable with that configuration, but it is unnecessarily difficult to do so. And stability is only one of the issues. Ultimately, it's an artists creation and no engineering has gone into it. Sorry to burst your bubble. It would be awesome if things like this could exist. But all of the numbers indicate that this design is impossible with a rechargeable battery of any currently devised chemistry. The only thing that would come remotely close to the necessary specific energy is a metal-air battery, but that technology is still a long way off for rechargeable cells. You could also use a non-rechargeable aluminum-air battery, but the operational costs would be difficult to address and there's no existing infrastructure to support battery replacement at airports.

I'm something of an "anti-skeptic", in that I sometimes feel that undue levels of skepticism are stifling innovation. Skepticism is warranted when people try to sell you something that has been proved not to work, but when new things come around I like to give them a bit more of a chance, in my mind.
