Convection occurs when lighter, warmer air rises and is replaced by heavier, cooler air sinking. To effectively harvest urban heat, wind turbines must be precisely placed where replacement air is entering to take the place of rising warm air. The rising air itself is not causing the wind, but the movement of cooler air into the space left behind. Any distance from this location means the effect dissipates. Harvesting heat in this way may slow the air flow cycle and create unique energy patterns. It could reduce the volume and density of air after energy removal, requiring more air to displace warm air and slowing convection. Heating during the day may return air flow to normal patterns or cause higher pressure over cities. Some heated air energy may conduct
