I wouldn't be so quick to dismiss the idea. Some of the claims are surely wrong, such as free-energy etc. but basically as an energy transfer and storage mechanism, as well as countring gravitation (which is a conservative force), there is no fundamental limit as far as physical science is concerned.
The reason for my optimism is that I saw a student at a University fair some time ago, who had built two concentric rings of different shapes connected by non-conducting rings, and the top ring connected to a CRT high voltage 40 KV (60 Hz) supply. Sure enough, the rings shot up about 10 feet in the air, and were held from going further up by the crt wire .
