I think if it's bi-directional, you'd need one-way check valves in the air chamber so the air moves through the turbine in one direction only.
Ung turbine po nya shapped like the wings of an airplane, nilagay sha sa loob ng tube, kahit na patulak or pahigop ung hangin na dumadan sa loob ng tube ang direction ng ikot ng turbine ay isang direction lan. Ung frequency nga lang nya ay hindi stable. Minsan malakas minsan mahina, kung kakabitan mo sha ng bulb power out nya para kang naglagay ng christmass lights na sira ung light controller.
