Dear Colleagues,
In These days I am performing very simple experiments at low
temperatures, down to 77K.
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.

*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
