Swartz has been working in this area for a long time. He has SB, SM, and SCD degrees in Course 6 (electrical engineering in MIT-speak; I also went there and my degree is in the same course).
Swartz's cold fusion generator (Nanor) was recently shown to generate a COP of 80. This is up significantly from that demonstrated at last years MIT cold fusion short course, where the same device was putting out a COP of 14.
One of the more interesting comments from Swartz was "...our device exhibits a COP of 80....attempts to reach higher outputs resulted in the device melting". Since the device consists of a dispersion of palladium nanoparticles in a zirconium matrix, this means that quite a high temperature was reached.
If you're interested in an excellent review of the science of LENR, I highly recommend Charles Beaudette's book "Excess Heat". It can be purchased from Amazon, or, if you don't want to shell out the bucks, your local library can borrow it for you via "Interlibrary Loan", for either no cost, or a small fee (usually just to cover postage).
Dr. Swartz says the technology will not be accepted in his lifetime. Due you know how old he is?
