Designs for an adjustable bottle holder were made but abandoned due to complexity. Five simple designs were drafted. Four designs were new while the middle size was a copy of the design made previously. All five designs were meant to hold bottle at various lengths from the axle to test the advantages of spacing versus space constraints. The current hypothesis is bottles spaced farther apart will provide higher torque with lower speed compare to relatively closer bottles. Results should show a speed which most closely matches the wind speed instead of being slowed by the resistance of the generator.
A method of bisecting 2-liter bottles had been delaying the process. Cutting the bottles with a saw or razor knife shouldn't be difficult but finding a method of accurately bisecting a bottle was not forthcoming. Originally the design was to build a jig which would encompass half of the bottle and make it easy to trace the cut lines. Since this device could be deployed to remote locations a simple method was preferable and the method decided upon was to fill a 1-liter bottle with warm water, pour it into the 2-liter bottle, lay it on its side, and trace the water line. Without a 1-liter bottle the method could be recreated by filling the bottle approximately half way then checking for accuracy by looking how close the water was to half way in relation to the cap and bottom. Warm water was used because cold water could cause condensation and prevent a marker from marking the sides.
