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.-- bs0u0155, Nov 08 2018 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.-- sninctown, Nov 11 2018 Err, open a window?-- not_morrison_rm, Nov 11 2018 [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.-- wjt, Nov 11 2018 random, halfbakery
