2 What is a Smart City? Swift TG Energy AP-VAWT Smart City is a hot and happening concept in the field of urban innovation right now. This concept assumes that a city operates as a system or a group of interlocked parts working together, where technology is used to maximize its efficiency and also unlock its potential, while its chief focus remaining on sustainability. A subsidiary of 'Markaz'

3 The consequence of Traditional Thinking is to add more external infrastructure and continue to rely on low tech, low hanging fruit conventional technology. >7% Transmission Losses

4 Sacrifice the Rural areas to sustain the Cities?

5 Plenty of Wind Energy in the city but it s Dirty, i.e. The wrong sort of wind! Conventional Solution: Harvest the Clean Wind outside the City and transmit it in?

6 What is a Disruptive Technology? According to Clayton M. Christensen, a Harvard Business School professor, a disruptive technology is a new emerging technology that unexpectedly displaces an established one. For example: Mobile Internet Internet of Things Advanced robotics Cloud Autonomous or Near-Autonomous Vehicles 3D Printing IntelligentHQ.com

7 How To Harvest Dirty Wind HAWTs can t react quickly enough to accurately track wind direction to maintain efficiency. Existing VAWTs do not need to accurately track wind direction to maintain efficiency but still have drawbacks. AP-VAWT will tolerate turbulence due to the inherent characteristics of VAWT designs plus self-start and maximise the potential harvest.

10 Key Features and Benefits Active Pitch Vertical Axis Numerically Controlled Modular/Scalable Design Continuously optimised power generation Omni-directional / Turbulence tolerant Self-starting Increased operating envelope Greater reliability in power output predictions Quiet operation

11 Optimum TSR Turbine efficiency Minimum TSR Swift TG Energy AP-VAWT 70% 60% 50% 40% 30% Self-start Conventional "fixed-pitch" VAWT WindSurf Additional generation opportunity Continuous optimisation Extended operation at extreme wind conditions 20% 10% 0% -10% Turbine operational TSR range

12 Start Up Criteria Current VAWT technologies typically require a minimum Average wind speed before initiating motion Gusty urban wind does not allow for easy prediction of cut-in conditions Average wind speed does not always give an accurate prediction of output power Typical fixed pitch VAWT minimum cut-in speed AP-VAWT start-up speed range
