Most of the criticism above is because it's _not_ about the Stanford cooling glove or any technology that actually controls core body temperature. All this does is change one's perception of hot or cold. Even if it did a perfect job of that, which it won't, it won't keep you from dying of hypo- or hyperthermia. It won't replace air conditioning because it won't do anything about the humidity in the air, which is a major discomfort factor in the summer in most non-desert climates. It's an interesting bit of psychology but it could do without overblown claims, and I personally view energy-saving as falling in that category.
