Great Hunt!
Looks like a cool and unique product with a good use-case in many regions. I spend the summer in my hometown and just got back a few days ago and friends told me the temperature in the city wasn't bare-able this summer and one even bought him a mini AC. With them now being in the funding phase a single piece is just about $60 USD so will definitely think about it to be prepared for the next summer.
Keep on the good work!
