Maybe, but two things to consider. The drag force in the fluid brake is proportional to the velocity squared. So you get harder and harder braking. (The air blades still need to not blow off though.) Insulation requirements decrease with the size of the reservoir. (Since volume increases faster than area.) Besides, the reservoir could be placed inside the house as well.
