There is a lot going on in battery research, I would have to read 10 times as much even to “skim” what is published every week, and undoubtably most of what is being discovered is kept secret.

Ford is risking a very very large amount of money on the 2 battery plants being built on I65 in KY and TN by relying on the technology of a Korean company that does not have a track record like Samsung or Panasonic/Sanyo. I would guess that relying on the workforce available in the Memphis area is risky, but TN government is throwing money that way.

Do not count out someone making a “Super Capacitor” breakthrough as well.

Every so often a volcano emits enough gas to lower the world temperature.

Ice core drill records now show us this in ways we could only guess before.

It is very reasonable to ask:
Are carbon dioxide, NOx and methane gases raising night time temperatures,
or has it been mostly “random chance” that less volcanoes than “average” have erupted over the last 150 years?

An historical fact that almost no students are taught:
