The energy savings from spot cooling with fans can be incredible compared to AC. A garage AC unit consumes ~1300W while a 20” fan consumes about ~150W.

My startup, Following Fan, has built a person-tracking 20” fan that uses computer vision to automatically stay pointed at the user as they move around. This technology provides the location agnostic benefits of AC with the energy consumption of fans.

But ac also reduce humidity. Fans just blow air, at high humidity and high temps the fan would be useless?

You’re right that fans don’t affect humidity and are less effective in extreme heat.

However, there are many places such as garages, airplane hangers, and large warehouses where AC is impractical due to a lack of insulation and the need to open large doors to move vehicles or goods in and out.

In those environments, fans are about the best cooling solution you can get. One big issue with traditional fans though is that they just point in an single direction or oscillate back and forth regardless of the location of the user.

Yeah, this is a big one for people in humid climates.

Here, it doesn't get that cold in the winter, but the house gets absolutely balmy and gross feeling. I have to turn the AC on just to get some humidity out of the air, despite it being in the 60s or 70s.

I have a dehumidifier also, but it can't do the job alone. It's really weird seeing how much water it sucks out of the air.
