Why Thank you! This my first time receiving positive comment on my micro turbine design.
I like the light weight of these plastic bottles plus even cooler becuase transparent.
Im working on 16 blade version.
This one will be much nicer
btw is that your design? the PVC pipe? Dont you think that is heavy material? Honestly you should try the same but with 2 Litre pop bottles. You be surprised how long it can last outdoors spinning
