Fog output and power consumption appeared the first problems. Power is supplied by two 4-D deep cycle marine batteries wired in parallel. Capacity is ramped up as well through a 2,500 watt inverter to provide 115 volts to the 1,700 watt fog machine for approximately 1.75 hours. This new powertrain generates 20,000 cubic feet of fog per minute, roughly a tennis court chest deep.
