There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.
If everyone who saw this today donated $5, we would meet our goal for 2019.

James McCanney is an astronomy crank and a conspiracy theorist. He's chiefly known for his "electric comets" claims, or, as he dubs it, "The Plasma Discharge Comet Model", but he's also a fair example of crank magnetism and appears to believe in all kind of fringe ideas. In addition to pseudoscience, his website flogs survivalist supplies.
The radio show Coast to Coast AM styles McCanney "Professor," and drops the name Cornell in association with him. However, his academic qualification is M.S. in nuclear and solid-state physics and he has not taught at Cornell University since the 1980s.
Comets are negatively charged. Ergo, they grow by attracting positively-charged cosmic dust. This IS WRONG. Comets reduce in mass over their lifetimes.
The Apollo Moon landings didn't happen. No human could have survived transition through the Van Allen radiation belts. They could and they did. Evidence includes the Laser Ranging Retro-Reflectors left on the Moon, the Moon rocks, and the images of the landing sites returned from the narrow angle cameras of Lunar Reconnaissance Orbiter. 
“”If you realize that comets are not dirty snowballs, they’re a discharge of the electrical conditions in the solar system, the first question out of everybody’s mouth would be, ‘well, can we use this for power?’ and the answer is ‘Yes!’ So what does that do to the people in control of the world? We’re talking about the bankers, the people in charge; they control the world through energy: oil, nuclear power, and coal. Those are the big ones. … These are very controlling forces, and if you took that away, one of their biggest tools to control the public would go away.

“”Planet X is real, and it’s going to come to us with a bunch of comets, and people murmuring about Planet X being out there is NASA preparing us for it.
