Cooling vest 4
Never give up! Talking to a co-worker about the wet cooling hat, he also recognized the potential and mentioned that they had cooled a wine-bottle with a wet towel in a boat during the summer. As the water had evaporated, the wine had chilled down. He thought it might be due to the fact that it was placed in the sun and that would remove more energy from the bottle.
Below is an example of a ceramic wine chiller, you put water in the chiller and place the bottle inside. As water passes through the ceramic, it will evaporate on the outside of the ceramic and thus cool it down as energy is taken from the chiller to the steam as the humidity will try to even out.
Here is another example of a ceramic wine chiller were the potter has not the physical insight and thus has decorated the chiller with glazing . Glaze is water tight and the chiller can not "sweat", thus it doesn't really work as intended...
Back to the hat, the cooling of a wine bottle from evaporation is not that effective since these kind of glazed wine chiller products exists and nobody seems to care.
How can we improve it?
If we blow on something it turns cold. Moving air over a hot body cools it down. So, maybe the cap needs to be blown on.
What can google dig up? Let's see... a patent?! Ohh, I'm not the first to have a go at this ;-)
Here's a link to the patent Hat with a fan
It's quite facinating to read about the improvements over other inventions in the area of hats with fans, and how the below hat is much better.
This is acutally worth testing I think... I'll try to email the innovator too see if this is in production and what his opinions are! I'll be back...
