It’s no secret that it’s much easier to create heat than to remove heat, which is probably why no one has created a “reverse microwave” yet.  It’s also one reason why there is only a small amount of clothing and accessories built around cooling people off outdoors, especially those who work in the construction industry.  Sure, you can install some fans around the job site, but they only help workers when it’s blowing directly at them.  Now, a Japanese company is releasing their personal cooling jackets and hard hat fans to US customers and targeting the construction industry.
