This ad ran in our local newspaper this morning. I just can't wait to buy one... as soon as I get the money from reselling my $600 hospital-grade a.c. line cord.
"This advanced heating element was discovered accidentally by a man
named John Jones. He had a large old farmhouse that was impossible to
heat. Jones had a coal furnace in his basement. Jones placed a sheet
of cured copper next to the furnace to store it. Cured copper is a
type of copper that goes through an extensive heating process that
gives it
special properties. After the fire went out, Jones noticed
that the copper was heating his entire basement evenly, even though
the furnace was no longer putting out heat. He also was amazed at
how long the heat stayed in the copper and continued to warm the
room."
Yep copper is a good heat sink. Read all about it:
