I do most of my work in notepade,,, but we all aware of energy shortage . sometimes it goes down suddenly. A person can forget to save it again and over again,

please suggest me any software that can save recent document(while writing) with interval of one second automatically...
MS WORD provides facility to save data after every 60 sec.. but it's of no use.
notepade++ also doesn't work,,,,,,,,,
please help me dears,,,,,,,,,,,,,,,,,,,,,,,
