Demo of a TEC1-04902 thermoelectric module like the ones used in the Cool India wearable technology project:
This is an unloaded TEC1-04902 at 5V constant voltage at 22.2C ambient and 42% relative humidity.
Starting temp is 36.7C and low temp is 11.3C, so total delta T is 25.4C.
Starting current was about 2A. At 11.3C current was 1.7A.
A 1.1 CFM Sunon B0503AFB2-8(MS) magnetic levitation (maglev) blower was used for the fan (specs here: http://www.hardwarespecialty.com/products/pdf/sunon/sunon_dc_brushless_blowers.pdf).
