[net.sf-lovers] Identify Story

smann (08/13/82)

Can anyone help me identify the following book or story:

There were two worlds - on one world (Earth?), someone
designed a heat pump which tapped an unknown source of energy
from the universe.
The other world was populated by beings who were differentiated
into three entities - emoters, reasoners & tactiles(?).  Together
they form a triad, in which form they can reproduce and are complete.
It turns out, of course, that their planet is in jeopard because
somehow they are losing their energy (the heat pump from earth is
draining their planet.)  One of the three of a triad - either
an emoter or a tactile - begins feeling strange and starts
acting like a reasoner.
Can't remember where it all leads to, - in fact, looking
this over, it seems pretty sketchy.  However, any help recalling
the title (& author) will be appreciated.
