Cooker hoods are simple devices with pure and decent
motives. They sit above your pot/pan heating surface of
choice and use a fan to draw away the inevitable steam
and hot air. If installed with care, they will be vented to
the outside. They are rarely installed with care with the
result that
they vent about 6 inches away, providing
nothing but noise.
The addition of a thermoelectric cooler could be used to
condense out the worst of the steam so that recirculation
would at least stop the smoke alarm going off so easily.
This device would be more expensive than the standard
type and so would never be bought by the sort of landlords
who can't be bothered running a hose through a wall. Also,
it would increase the net heat in the kitchen and need a
drain hose installed, which probably wouldn't happen, so it
would just drip into your eggs.

Just in time for this year's holiday season...a lid that
won't drip steam drippings everywhere! |

In principle, this would work great. A simpler alternative
would be an aluminium heatsink: since the kitchen air is
already sufficiently cool to condense steam, all that is
required is a heatsink which will readily convey heat from
the lid to the kitchen air. A practical realization of this
idea would be to attach a desktop computer CPU heatsink
(complete with 12V fan) to the lid of one's pot/pan. It
would be prudent to use a concave lid (instead of the
typical convex lid) so that the low point of the lid (where
water naturally collects) is in the middle. In operation,
this device would condense water and allow it to drain
back in to the pot, greatly reducing the amount of steam
vented into the kitchen. |

A more cumbersome solution would be to plumb a vent
hose to the lid of your pot, and route this vent hose
through a Graham condenser (cooled by tap water) and
draining the condensate into your sink. |

For a quick fix, a box fan (20 inch or 50cm size) placed
next to the stove would probably suffice. |

[not_morrison_rm] stoves can be cornered away from venting pressure gradients. |

[sninctown] It's not space. The water should really be put outside. Your right, the heat not so much. |

Some super computing vectoring graphics would be beautiful to look at. |
