Comment caused by friction or by water drops "rolling"? (Score 1) 47

My guesstimate is that water drops, held together by surface tension, primarily roll across the surfaces accumulating charge. IOW the charge accumulation is not a result of friction (it's not "triboelectric") - the droplet acts like the belt in a Van de Graaf generator: https://en.wikipedia.org/wiki/... So rain drops "roll like a ball" or "roll like a belt" (flattened ball), picking up charge at the front and depositing it at the rear of their path. When they fall off the edge of a surface, they carry any accumulated charge with them to any surface they strike e.g., a sheet of galvanized metal below.

Comment Landlines do not fail in a hurricane (Score 1) 123

The phone company doesn't want to maintain that even though it was part of the original deal when they were granted a monopoly.

Comment Coal Tech Can Quickly Rebuild After Nuclear War (Score 3, Insightful) 71

whereas the high-quality materials (and engineers/scientists) for nuclear plants would not be available, nor could they be created for decades after a war. But coal is a well-known proven tech, can be used to produce steel and get the manufacturing base back up to speed quickly, even if there is no sunshine (due to nuclear clouds around the earth).

Comment USA Not Stolen: Indians Were Wiped Out By Disease (Score 1) 126

The American Indians (both North and South) were doomed when the first European walked ashore and was greeted. The Indians and their ancestors had no exposure to European diseases and so, as soon as the European coughed, farted or offered his hand as a gesture of friendship, the match was lit.

The flame spread as Indians returned to their villages. It turned into a conflagration spreading in all directions slaying Indians before it. As the white man advanced, he sometimes found entire villages, sometimes entire civilizations, struck down where they stood: tools and implements scattered about among half-eaten bodies, dwellings, and crops in the field unattended,

The fate of the American Indian was sealed by his/her geographical isolation. And the American Indian could give as well as get. Syphilis was a disease that was spread from the Americas to Europe.
