According to some embodiments, a system to improve heat transfer for a data center may include a substantially cylindrical data center tower. The data center tower may include a data center tower bottom having at least one bottom opening to receive external air and a data center tower top, smaller than the data center tower bottom, having a top opening to expel air containing heat, created by the data center, via the Venturi effect. A plurality of hydrophilic bladders may be located proximate to at least a portion of a side of the data center tower, and plurality of data center computer servers may be arranged proximate to the side of the data center tower. In some embodiments, a heat capturing bottom portion of the side of the data center tower is formed of transparent material and/or a translucent material.
