There doesn't appear to have been any melting inside the tube. It's interesting that the fuel formed a small diameter cylinder. There was also a small amount of fine powder left in the cell.
The fuel is shown in the picture (looks like a little stick). http://www.lenr-coldfusion.com/wp-content/uploads/2015/03/IMG_20150317_134300_957.jpg On Tue, Mar 17, 2015 at 11:39 AM, Jack Cole <jcol...@gmail.com> wrote: > To add a couple of more details.
