Thanksgiving was once a thankful time.
On this date in 1993 Piantelli and Focardi had just performed what was the
World’s first successful long-term Ni-H gas phase LENR experiment.
The prior work of Mills is not nuclear, according to him. The Thermacore
meltdown happened in 1996.
No radiation was seen by Piantelli and no evidence of anything nuclear was
shown - so it is not clear if it was LENR or some other anomaly.
Summary results: Cell "A" produced 39 watts of heat for 278 days. The
integrated excess energy was 900 MJ. The other cell was less gainful.
The input power required to maintain the unloaded Ni sample at a fixed
temperature can be up to twice the one required for the loaded Ni. This power
imbalance ca be considered the gain of the system, even without confirming
calorimetry. The actual gain ratio (COP) is nevertheless in the range of 1.5
This paper was believable and many dozens of similar papers since then have
demonstrated about the same level of COP in Ni-H gas phase, which is in the
range of 50% more thermal power out than electrical power in. The most
believable report was from Thermacore, since they were World leaders in
thermodynamics. They ran for over a year at COP of about 1.5.
Here we are - decades later and with more questions than answers. Some
experimenters who reported small gain years ago (Ahern) think there is almost
no future in the field since the COP has remained too low to attract interest.
Many observers would be very satisfied to see a bona fide and reliable COP
level which is greater than 2 if it can be independently verified.
Verification/replication is the key.
