This should serve as a caution flag to experimenters. The effect that lead to the explosion needs to be determined and may serve as an additional clue about the process involved. It is not surprising that he saw a PTC which I believe is normally assumed at the higher typical temperatures of operation.

I am using two wires, one with 2 Layers (called "nanodiamandois") and the other usual with 500 Layers, Both of Constantan type ISOTAN 44. * Under vacuum and / or He (2.5bar), I detected a PTC (Positive Temperature Coefficient) with the 2L Constantan (about 4%). 500 With Layers The NTC detected (about 3.5%). * When I added H2 (2.5bar) During cooling down, at a temperature of about -50 ° C, The EXPERIENCEDEXPLOSIO N. * The bottle, nominally tested at 16 bar at 50 ° C, was completly destroyed. No. iniury to us, thanks to the open plastic tube used as dewar. Just big noise. * There is a Possibility That Such material is cathalitic even at low temperatures, as reported by Also in old paper of Hydrogen absorption at low temperatures using Constant tick film. !! PLEASE, SHARE SUCH INFORMATION TO ALL THE PEOPLE INVOLVED in the replication efforts. Dear [omitted], put in the MFMP Such new blog, ASAP! Tanks for your collaboration. Francesco CELANI Shortly after one of the recipients of the email responded in this way: Francis, Thank you for the warning - most interesting. Also I can add a warning - we have had a runaway event with Cuprothal 49 - from a constantan alloy Kanthal (9 meters of 0.7, wire prepared in our own experiments) at a very modest temperature: <180C. Fortunately the event was contained in a titanium tube reactor Although it melted the tube Which gave at least as the ability to estimate the temperature and power output at 800-1000C for 30-60min resulting in an estimated power output of around .5-1kWh. This incident occurred During cool down after the completion of several weeks testing and with all electrical inputs disconnected ... I know it appears that a runaway event is possible with zero input under conditions That are difficult to predict / reproduce. Cheers
