C.Krafft

[GaryN]

C.Krafft was mentioned briefly in a previous post, but a 'Net search didn't come up with a whole lot about him, except behind the doors of Spingerlink and other similar sites. I'm looking to collect some info on Mr Krafft, and would appreciate any leads or articles that TB members may come across.

Biknewb passed this link on to me:

And here is the intro from his "Earth, moon and planets". He refers to Bostick and Alfven.

Duncan Steele refers to Kraffts book "Earth, Moon and Planets", which I can not find on-line, but apparently was donated to libraries. Ill have to check on that.

From Mr Steels "Electromagnetic perturbations of the orbits of asteroids":

There are several distinct forces that may act upon an asteroid due to its interaction with the interplanetary magnetic field. Here the Lorentz, Faraday and eddy current forces are considered and shown to be several orders of magnitude weaker than the radiative forces (radiation pressure, Yarkovsky force). These electromagnetic forces are therefore unlikely to be significant with regard to predictions of terrestrial impacts. Two other points are noted. One is that an electrical current flowing through a small solar system body will cause Joule heating, and it is suggested that this might be the mechanism responsible for some cometary fragmentation events.

The electromagnetic forces are weak, but what level of charge could be built up? Enough for fragmentation to occur, I'd say. And what about a metallic planet traveling through the Suns magnetic field? What kind of induced charge there?

Lots of links to info and articles penned by him. He now works for QinetiQ, part of your friendly Military Industrial Complex.
