By the way - 6th grade math - 6kV * 10kA is 60MW of energy (which is actually a pretty weak strike). Old Colin is right, not much energy there at all...
Again, a demonstration of knowledge from advertising and emotion. One should know that simple stuff long before denying and attacking. Those most easily brainwashed only understand accusation and personal attacks. MW (watts) is not energy.
6kV exists when something (ie magic power strip protector) foolishly tries to 'block' or 'absorb' a surge. If he reads with intent to learn, then he knows an effective protector never 'blocks' or 'absorbs' a surge. But once brainwashing from advertising takes hold, then reality cannot be learned.
Effective protection is at least 50,000 amps. Then hundreds of thousands of joules (destructive surges) dissipate harmlessly outside. Then even a protector is not damaged. Effective protectors are not rated in joules. Scams are.
If not yet obvious, energy is measured in joules. Power is measured in watts. Effective solutions are measures in amps. Anyone who learned from honest sources would have grasped that simple concept long ago. Brad Humphrey wants to attack and demean. So he *knows* 60MW is energy. He could learn from Richard Harrison, Colin Bayliss, and the so many others who discuss well proven science; were not brainwashed by hearsay, wild speculation, a nasty attitude, and advertising.
Emotions replaced knowledge here long ago. These same people foolishly knew Saddam had WMDs, communists were conspiring in the State Department, and Jews were vermon. They only know what they are first ordered to believe. Somehow watts measure energy - because fables said so.
Don Kelly (another educated by science - not fables) discusses why so little energy can be obtained from lightning:
Yes there is a high peak power in a stroke but this does not translate into appreciable energy (about 55 KWH (200MJ)for an average stroke). Energy is what we need, not high peak power.
Since power plants output impressive values (tens of thousands of volts and hundreds of thousands of amps), then those inch diameter, high tension, power cables are instantly destroyed by hundreds of megawatts - using Brad Humphrey's reasoning. One should learn how the world works rather than recite parables. As if megawatts magically measure energy.
Turn in that elementary school graduation certificate. He did not earn it. Or he is only getting senile and nasty.
