Towards the end of actually designing the house and everything that was involved in "STEP 4", we did a small lab on wind turbines. The objective was to build multiple propellers and place them in front of fans. This was done so we could analyze what types would spin the best. Ideally, we wanted the propellers to spin quickly and for a long period of time. We tried multiple variations out: small long ones, short thick ones, etc. At the end, out of all the ones we tried, we came to the conclusion that a small turbine at a horizontal axis worked the best.
