    yes sir,
    u r right its proved by peteir effect only... by mit student
    n he made a climate control jacket by using thermocouple...

    i have searched so much but not able to get technical details ....
    how is that made possible..
    they say they r using a lap top sized battery
    they beark hydrogen ion..
    the temp inside the jacket will be maintained from 18 to 40 degree
    when the atmosphereric temp. is from -30 to 50 degree....
    i think they use semi conductor too....
    as per as my info...

    thanks for replying...

    plz do replyy.....
