Solar powered fans in suits
Caregivers are exposed to very hot conditions when responding to patients on the scene. This idea helps circulate cold air within the suit by a solar powered computer fan. This will cause the suit to inflate more, so putting rubberbands at the pivots of the body, like the elbows and knees, would help caregivers retain their mobility.
Suits that are currently used can be fitted with flexible solar panels on the shoulders which is then connected to a computer fan on the back. Rubberbands on the elbows and knees can contrain the cold airflow into the arms and legs.
