| > Is there any kind of CO2 scrubbing that's at all practical for home? Not scrubbing in the way that a power plant does, but you can improve ventilation, but you probably need to do more than crack a window. Options from cheapest to most expensive (in upfront cost): 1. Run your stove extractor fan (assuming it is externally vented), and open the window that is furthest from it in the house. 2. Open 2 windows and put a fan in 1 facing out, and if it's winter, wear a sweater. 3. Install a whole house ventilation fan (i.e. Panasonic Whisper Green fan) and keep the furthest away window slightly cracked. All of the above will cost less upfront but will result in a significant increase in your heating/cooling energy use during hot/cold seasons. If you want to minimize the increase to your heating/cooling energy use, then you need to spend more upfront and: 4. Install a whole house <heat|energy>-recovery-ventilation system. This system brings in fresh air 24/7 while transferring much of the heat/"cold" from the conditioned space to the fresh air from outdoors. What all of these solutions share is that they don't rely on wind/convection to ventilate the house, they are all mechanical. |
