Solar-powered fan system
Designed to provide comfort in both cool and warm weather, the MacroVoltaic fan system mixes elevated, warmer air with cooler air nearer the ground. A 5-mph speed and 360-degree circulation allow the fan to achieve the same effects with 400 watts as comparable models that consume 64 times as much power. Solar panels supply direct-current energy, which is converted for use by a controller coordinated with the fan’s motor.
