FUD. It’s not lightning.
- martin_a 7y agoThe effect is the same, does not really matter what causes the current gradient in the ground.
- Dylan16807 7y agoYou need a huge voltage density. Ten volts between your feet is going to do nothing at all.
- gspr 7y ago> You need a huge voltage density. Does voltage density make any sense?
- ncmncm 7y agoProbably meant gradient. Fun fact, voltage gradient across cell membranes is typically megavolts per meter. At scale that is millivolts per nanometer, but the field strength is the same either way. Membranes are badass.
- hwillis 7y agoEDLC's operate at several gigavolts per meter, across a gap only atoms thick. They actually do it the same way as a cell wall -ELD stands for electrostatic double layer- by lining up two sheets of polar molecules, with charges facing each other.
- martin_a 7y agoI'm not aware of anything like "voltage density", what do you mean by that? The potential gradient is the thing that kills you. It can either be created by a lightning strike or by voltage induced into the ground as mentioned here.
- Dylan16807 7y agoI'm talking about the potential gradient without bringing up new terminology. > It can either be created by a lightning strike or by voltage induced into the ground as mentioned here. If 'it' is lethal levels, then I don't think that 'or' is correct.
- ncmncm 7y agoDoubt is was meant as FUD. Normal confusion suffices. Ground currents are interesting however they occur, and are novel to many. The remarks were correct about lightning.
