My most immediate question (after others you already answered in this thread) is about getting enough CO2.
When you start absorbing CO2 from the air, won't the CO2 in the neighborhood be depleted very quickly? And I'm assuming you can't pump enormous amounts of air either for various reasons (noise, energy usage, other environmental issues).
Of course there's wind to bring more CO2, but I'm curious about your computations.
- maelito 7y agoDon't you just need to open a window and wait a few seconds to desaturate a room where too many people breathe ?
- sjg007 7y agoDoesn't matter, air is a fluid, so diffusion works in your favor.
- rmcginnis 7y agoThis won't be a limiting factor. It won't be stagnant air, and the diffusion rate for gases is high.

- jtolmar 7y agoThey're looking at cheap off-peak electricity sources, one of which is excess wind power at night, so they're likely to be operating when the wind is blowing anyway. (Not that they need it - gas diffusion is fast - but it's a cute synergy.)
