Abstract
Bill Gates, founder of Microsoft and one of the most philanthropic men in history giving over 28 billion dollars to charity so far, states his number one wish for the world wouldn't be to rid the world of aids, vaccinate kids around the world, or feed every starving children; instead, it would be to invent and utilize a cheaper emission-free source of energy. My research aims to cut through the vast amounts of wind turbine designs and analyze the two most promising types. The first type is Small Vertical Axis Wind Turbines (VAWTs), roughly 1.5 meters by 1 meter and generating roughly 500 watts. The second subclass which is less easily defined but generally termed modified or innovative horizontal axis wind turbines (HAWTs).

In fact, The U.S. Department of Energy is pushing to have wind energy reach 20% of energy production by 2030 [2]. My research has also unveiled that traditional wind turbines are just not viable in most urban environments, although they have been implemented in many situations already. Traditional wind turbines are not the optimal solution because they cause electromagnetic interference (EMI), acoustic pollution, and size constraints [11]. Traditional wind turbines can have a diameter of 80 m and need to be able to rotate to face directly into the wind [11]. In most urban environments these dimensions are just not feasible. Vertical axis wind turbines and modified horizontal axis wind turbines also move slower than traditional models reducing some of the negative side effects. Figure 2
These slower moving technologies drastically reduce turbulence, vibration, and danger. The focus of my research will be on Vertical Axis Wind Turbines (VAWT’s) and some of the more innovative, modified HAWTs. Figure 1 is an implementation of a VAWT that is particularly interesting. It is produced by Urban Green Energy and it is a great implementation of a VAWT on a street lamp. Figure 2 is a modified HWAT installed on a European building. Many people believe VAWTs are a new technology; however it is actually an ancient technology adapted from the turbines used by the
