You would have to fold the top of the blanket back,
to avoid the cold shoulder. |
|

Hmm, I don't actually see that as a problem unless the shoulder is the only point of contact. |

The deluxe model has a chest for heating or cooling your drinks. |

I'm awed beyond the ability of one + vote to
express with how simple and cool (no pun
intended) this idea is! |
|

So would the blanket just something like a sort of
brigantine of chunky Peltier modules with lots or
wires running to them, sandwiched in crinkly
Mylar, or to somehow make the whole thing
flexible and homogenous? |

A side application would be that, removing the
power supply, you could use one rolled into a
sleeping bag as a generator to charge your small
electronics using your body heat – quite the boon
for outdoors folk with a need for ever present
radio and IT connectedness. |

There doesn't seem to be a soft, furry material for Peltiers, so I'd go with a large number of extremely small disks, say 1cm area - sequins really - covered with a fabric just thick enough to keep the little disks from being noticeable. |
