Tibetan monks used to carry small
charcoal braziers under their robes to
keep themselves warm in the winter.
It is silly to heat or cool a whole building
when all you really care about the
temperature in your immediate vicinity.
Since we do most indoor activities on one
piece of furniture
or another why not just
control the temperature of the furniture
with an air heat exchanger that blows hot
or cold air through the side of the
furniture that we touch.
A peltier junction (solid state cooler) and
blower heats or cools the incoming air and
vents the waste heat/cold away from the
The furniture could have a pressure switch
to shut itself off when you were not using
||I need a heated mouse and a keyboard that blows warm air in my face. Would allow me to hack along at 50F instead of 70F. I already have a heating pad under my feet in winter.
||The improvements in my scheme would
be that liquid is not involved, so
condensation, leaks and punctures are
not a problem and you dont need to run
the garden hose into the furniture or
deal with 500lb chairs..
||Using air as the heat transfer medium
also creates a warm or cool breeze that
surrounds you rather than just cooling
or warming the part of you that is in
contact with the furniture.
||Using a peltier junction lets you choose
heating or cooling and the degree you
want of it.
||I did not mean to imply that the peltier
junction could magically dissapate heat.
||Re the heatsinks, a smaller heatsink
works fine if you move sufficient
volumes of air past to carry away the
|| My scheme calls for fans to move a
large volume of air on both the hot and
cold sides to distribute the desired
temp air and dissapate the waste temp
A peltier device will quickly cook itself
to death without something sucking the
heat away, so it makes sense to use
You might be able to make it so the
wast heat/cold keeps your coffee/cola
||Also many people dislike the idea of
being under the emf that electric
blankets give off
