If you haven't been watching Zero Breeze then google it. Small portable scroll compressor AC unit that looked promising. However after raising over $1MILLLLIOOONNN it looks like it's just another scam. See the comments on their www.
So the transmission goes out on the Explorer Friday and can't be fixed until Monday, and I have to work. On the road sales. 98 degrees + humidity and my backup car is the teener.
Take a 28qt ice chest, blend it gently with hole saws, epoxy in a pipe and a fan.
Add a bag of ice and everything in the freezer and away we go. This really worked for an hour keeping me cool enough but not super cold. Then the ice melted.
Verdict? I'll be using it again tomorrow. Just know it's ah hour between ice stations.
