Great video! The pharaohs used a device known as the "cylinders of the pharaoh" made from copper and zinc cylinders filled with quartz crystal when held produce electrical energy starting at .6 volts and will gain .01 volts every minute held so after an hour you will produce 1.2 volts. Similar to a galvanic battery cell the copper is the cathode, zinc is anode and you become the electrolyte left side negative right side positive. Quartz emits infrared energy, is pyroelectric and piezoelectric. Make them yourself or get them on amazon or etsy.

Is this like pemf?
