Can deuterons in palladium condense into a BEC?

In this earlier post, I introduced Yeong E. Kim’s Bose-Einstein Condensate (BEC) theory of cold fusion. According to this theory, when you pack lots of deuterons into palladium, they condense into a BEC, which makes nuclear fusion possible, and then the fusion energy is collectively absorbed by the BEC, thus explaining all the mysteries of cold fusion. In my earlier post I said that the two biggest problems with the theory are: (A) The deuterons do not actually condense into a BEC; and (B) Even if they did, it would not help explain cold fusion. I already blogged about (B) hereToday I will talk about (A). I have changed my mind: Although I suspect that deuterons would not condense into a BEC, I don’t know enough to say for sure!   😛

In this post I’ll mainly just summarize Kim’s argument. If anyone reading this is a BEC expert, please comment (or better yet write a guest post, just email me) with your opinion!

BEC 2: Coulomb barrier in a BEC

In the previous post, I introduced Kim’s Bose-Einstein Condensate (BEC) theory of cold fusion. I said that the two biggest problems with the theory are:

  1. At room temperature, the deuterons cannot condense into a BEC.
  2. Even if the deuterons condensed into a BEC, they would not undergo nuclear fusion, for the same reason as usual: Because the Coulomb barrier prevents them from getting close enough.

In this post I will just talk about #2. So for the time being, please assume for the sake of argument that the deuterons really do condense into a BEC. The question is: Will that make the Coulomb barrier problem go away?

BEC 1: Overview

Yeong E. Kim at Purdue and colleagues have proposed that, in cold-fusion experiments, the deuterons condense into a Bose-Einstein Condensate (BEC). In this state, he says, they can fuse, and then the energy is collectively absorbed by the BEC. (If you’re not familiar with BEC’s, here is a very simple introduction for non-physicists, and I’ll explain more as we go.) According to him, this theory meets all the theoretical challenges of explaining cold fusion.
