Deborah Chungs appearant negative resistance.

[antimony]

Hi, yesterday I saw an episode from the Energy from the Vacuum series, about a material scientist with a background in electrical engineering called Deborah Chung. She was working with carbon r&d for new applications, when she discovered some interesting electrical properties carbon fibers have.

Do anyone know more about this womans work, and are willing to Share their knowledge with me?

One other thing she said in the end of the interview that i found very interesting also was that cement or concrete also possess these "appearant negative resistance" qualities like carbon fibers do.

Don't waste your time on negative resistance!!!! There is no such thing. The real name of these devices is 'differential negative resistor'.
They always need input power and never give it all back. 
Those who don't understand, make a big deal and even documentaries about something that is not actually that special for the OU enthusiasts.

I havent looked into it at all, and after the episode i was checking o/u to see if there was anything on Chung here, but I did not find anything.
And there May be a reason for that in your reply.

My logic was like if there really was something in this, people would make a lot more noise about it.

What is it that they are seeing in this that suggests OU?

What people see in this is a lack of understanding about what negative resistance is.  As a couple of posts have already explained it is not what people think it is.  The basic problem is that most people that are pursuing OU have never taken the time to learn the basics and language of electronics so they misunderstand what is being said or explained.

An example of this is the term self exciting generator.  I have seen so many people get all excited because they found a patent that describes a self exciting generator.  Because they don't understand what that really means they jump to the conclusion this means a generator that can power itself.  That is not what a self exciting generator is.  Self exciting just means the magnetic field for energizing the power coils comes from the residual magnetism and a circuit that allows the residual magnetism to build so it can energize the power coils.  You still have to have an external power source to turn the generator.

I could go on and on about the other misunderstood terms and devices in electronics such as magnetic amplifiers and vacuum tube amplifiers.  None of these devices amplify power.  They only amplify the signal.  The small signal controls a larger current flow.  But something else has to supply the larger current flow.  So while they do amplify the signal there is no power amplification.
