- I`ve just read an article in New Scientist Oct.31 issue (British science
- magazine) about the experiments of Eiichi Yamaguchi of NTT.
- They sound quite interesting, and are claimed to be easily reproducible.
-
- It appears he takes a `chip` of palladium (3cm x 3cm x 1mm), one side of
- which has been oxided and exposes it to deuterium gas so
- that it becomes saturated (high pressure ?). The other side of the chip is
- then coated with
- gold (to seal it?) and heated (how much?, in a vaccuum ? or in a vaccuum-tight
- container ?).
- After several hours, he observes a 100 C rise in temperature in the chip.
- Also, He4 is detected in the chamber.
- He apparently believes that deuterium `migrates` toward the Pd-oxide side
- where it fuses to form He4.
- He also claims that `at
- the peak` , 1 million-billion (10^15) fusions per sec occur.
-
- An alternative interpretation due to David Williams of Harwell is that the
- heat is due to oxidation of the deuterium (presumably due to the oxygen
- in the Pd-oxide layer ?) to form D_2O, while the He4 is due to impurities in
- the glass container. I presume however that this can be checked by using H
- instead of D (have they ?) and/or looking for D_2O. I would imagine also
- that repeating the experiment (as was done 5 times with `perfect` success)
- but with the _same_ container could also be a check.
-
-
- Can anyone provide more information on this experiment ?
