Good observation. Yes it is slightly unbalanced. The blades are unsurfaced i.e. not smooth but rough which is a material mass distribution inaccuracy. Only noticable at 200 rpm and above. Vibration is caused but the blades are totally scilent due to the lack of blade tips. The air speed for this video is only 13 Kph average. Its pulling near 120 rpm. It is deisgned for performance in disturbed & limited air flows noticed in domestic settings with height restrictions.

WORLD RECORD: BIGGEST WIND TURBINE

ZERO-NOISE from the gears and the generators because they are sealed underground (Only the outer parts of the turbines may be heard.).
SAVES THE BIRDS AND BATS because the turbines are slow-moving since the speed is in the transmission gears and in the generators.
DOES NOT NEED TO OCCUPY WIDE LANDSCAPE because the turbine can be very tall.
HELPS THE WIND ENERGY COMPANIES because it is FREE FOR ALL.

Good start, I personally built one some months ago. It's a good choice for very strong winds in residential areas.

looks to me like its unbalenced, causing vibration, noice and reducing efficiency?
