But whatever sticks out into the airflow, is not very streamlined as a rule.
These gaspods are streamlined shapes, so while they will still push a bit of air up and aside, it won't be much, and it'll be done fairly gently, allowing the air to return to where it was before ... so where would their claimed effect come from ?
