More written details to follow soon

in the meantime, here are some photos, graphs & a schematic of the latest experiment

the system shown below has been operating non-stop since 8th Dec 2010 (approx. 1000 hours at time of writing); during this time, the on-load terminal voltage has been sustained/recharged by ambient room heat, whilst at the same time being loaded by the LED Flasher circuit shown

on-load terminal voltage, Vcell, of DIY cell + LED Flasher cct
vs. ambient temperature, Tcell (as at 15 Jan '11)

Example completed DIY cell

Full system located inside steel case

LED Flasher circuit

in a few days time, i'll post graphical data for the terminal voltage of an unattached DIY cell vs. ambient temperature

after another week or so, i'll post graphical data for a 'control' test, using a similar LED Flasher circuit powered by two commercial 1.24V 1000 mAh NiMH cells, contained in a similar steel case and subjected to a slightly higher upper temperature swing
