Thanks for the thoughts. We think it could be especially useful in places such as warehouses, auto shops, and garages where there is no air conditioning but get extremely hot in the summer.
That is a good point. Large ceiling fans are one solution and probably superior when there are a lot of people. However, Following Fan is more efficient when there are not a lot of people since it will be less than 1/10th the cost of a 14' ceiling fan, use less energy, and provide more focused airflow to a specific person.
