Depalma Free Energy fields Few years ago I read some papers about Free Energy, written by Bruce de Palma, a physicist who is said to be the inventor of the N-Machine, which is an device that works with free energy latent in the space around us. There are several informal references to him and his work. However, I tried to find papers of him several times in Scielo, Science Direct, IEEE, Physical Letters, Nature and several other scientific databases and found no references to Dr. Bruce de Palma. Personally I find quite strange that a research of such importance do not have a formal paper in an journal of big impact. 
Does his work make sense?
 A: The claims are absurd--- you can't extract "zero point energy", because it just isn't there--- energy is extracted by moving something from a higher energy state to a lower energy state, and the vacuum is the lowest possible energy. Nevertheless, there are many fraudulent claims to the contrary, and this is one of them.
In response to comment
It is easy to dismiss claims that there are new fields affecting material substances--- there aren't any such fields. The author here does not provide evidence for these fields beyond speculating, and if these fields could produce macroscopic forces in matter, they will generically generate friction in materials, so that you would notice missing energy which is radiated into these modes. This is too obvious to miss.
Further, even if there were new fields, in their vacuum configuration, they would be useless for extracting energy. You would need to find an excited configuration and drain out the energy. This stuff is not worth the bother of reading it.
