We have used electricity on Mars. The Mars rovers, Spirit and Opportunity had solar panels to keep their batteries charged.
you are not asking anything or saying anything that isnt common knowledge, it as if you lack direction to what you are seeking , maybe you dont know what you are seeking and this is your way of asking for direction?
however what is not common knowledge was in my original post. two devices operating at same frequency or rates communicate energy with each other
by my orignial post in the thread (about tesla's discovery) you can see i am tryin to inspire a creative force in people with this (his) knowledge. they can then create a question of as to whether what would benefit they can detain by operating two devices at same frequencies, at a distance, to communicate energy?
