That would only be possible if E-kitten used a different physical reaction than the E-cat. This is very unlikely. >* * > >*There was no lead shielding (lead shielding was removed) on the >E-Kitten(2.4 kilowatts thermal output) during its demo then during the demo >of the Cat-E(18 kilowatts).* > I believe the E-kitten actually used for the test was the one which still had cladding (far right).

If any fusion is taking place, then I suspect there will be at least some immediate radiation (probably X-rays or gamma rays, and the ratio between the two is probably still unstable this early in the lifetime of the device). > >* * > >*In the Cat-E system, a thermal spike of 130 KWs might have resulted in a >production of a gamma ray spike that are often detected on the larger Cat >systems.* I think the gamma spike is caused at start and end because at those times the Hydrino shrinkage level is less than during normal operation. When the Hydrinos are very small, the IC reaction predominates, resulting primarily in fast electrons that produce some X-rays (1%), but at startup and shutdown, the Hydrinos may not be shrunken quite as much, allowing gamma ray production to predominate. The X-rays are mostly soft, and largely shielded by the Lead. > >* * > >*This peculiarity of Cat-E megawatt design may well have been discovered >recently and has led to the fabrication of the one megawatts Cat-E unit with >many more E-Kittens.* > >* * > >*This would defang the NRC and would be worth the extra material cost the >build the megawatt unit due to larger numbers of smaller E-Kitten modules or >channels. * > I think the smaller size is because the instability has turned out to be larger than expected, and Rossi is trying to maintain a stable output overall. There is also the fact that if a small device explodes, it doesn't do as much damage as when a large device explodes. [snip] Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
