We have storms with over 1000 strikes in a half hour. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.

The fact is, a lightning pulse is so short, with such a risetime, it will be hard to steer into any load. > > I dunno, it'd need to be a tall 1MV / 100kA = 10-ohm resistor > with water cooling, or something. But if rated at a puny 1MV, > it wouldn't warm up much water, with only 1MJ of energy. Sigh. Yup. Lightning is all show. > >> We don't get lightning here. I kind of miss it. > > Yes. In New Orleans, you could sit on the Lake Pontchartrain levee and watch massive thunderstorm fronts sweep in, with beautiful and noisy lightning. It was usually warm rain and made warm puddles, so you could sit there and get wet and really experience things. Here we get pretty dramatic fog shows, some compensation. John

They drop down from a mile in the sky. They can surely make it across ANY two terminal device you think you can come up with. Unless you are separating the nodes by over a mile. My cap would flash over as well, but more would remain stored than in any of the scenarios discussed here thus far. No math required. |
