Huh... I think your thinking of a *super-conductor* which work
only at very low temps allowing the e-'s to travel along thin
paths of no resistance: because if they were any hotter they bounce
right off the no resistance path. Normal metals' resistance goes
down as the temp goes up because more e-'s fly off the atoms: if
it got hot enough you get plasma: a soup of electrons and other stuff.
Oh yeah plants. Well after two weaks of heatwave my -sob- Darlingtonia
are dying of heat stroke. Of couse the year I get a good quantity
of them going, heat and heat and heat AAAAAAAAAAAAAHHHHHHHHHHHHHH!!!!!!
Perhaps they just don't like all those extra free electrons in their
roots.
