Now as I am extremely slow when it comes to technical issues being a marketing guy, I dont fully understand this concept very well....
....now the "KoolerAir" unit in the link is sucking warm air in, using ice to cool the air and then blowing it out. ok....I understand this concept.
Your peltier fan idea I assumed did not use ice as your thinking was that the peltiers and cold plate absrob the heat from the sealed mirror area and blow it cooler air back on the mirror surface right? Is the cold plate on top of the perspex and on the outside, or on the inside facing the mirror?
I also thought peltiers worked by taking heat away not blowing cold air back in? is the fact that the ambient is lower on the outisde dealed tub means that the air being blown on the mirror by the peltiers is colder than the mirror it self? therefore the mirror will cool by thermaly equalizing?
