Hacker News Stories and Comments
All the comments and stories posted to Hacker News that reference this video.Here is the list of house/indoor plants which promote cognitive function in order of ease of maintenance:Areca Plam (Chrysalidocarpus lutescens AKA Dypsis lutescens) https://en.wikipedia.org/wiki/Dypsis_lutescens
Mother-in-law's Tongue/Snake Plant (Sansevieria trifasciata) https://en.wikipedia.org/wiki/Sansevieria_trifasciata
Money Plant (Epipremnum aureum) https://en.wikipedia.org/wiki/Epipremnum_aureum
Boston Fern (Nephrolepis Exaltata) https://en.wikipedia.org/wiki/Nephrolepis_exaltata
Peace Lilly (Spathiphyllum) https://en.wikipedia.org/wiki/Spathiphyllum
Gerbera Daisy (Gerbera jamesonii) https://en.wikipedia.org/wiki/Gerbera_jamesonii
Spider plant (Chlorophytum comosum) https://en.wikipedia.org/wiki/Chlorophytum_comosum
English Ivy (Hedera helix) https://en.wikipedia.org/wiki/Hedera_helix
Take the list of plants to your local plant nursery to see how many of them they have in stock. Buying them already established is much cheaper/easier than growing them from seed/cuttings.
According to Allen et Al 2015 (see link below), having pure/fresh air in your working environment significantly improves cognitive function. i.e. having indoor plants makes you smarter!

> Conclusion: Office workers had significantly improved cognitive function scores when working in Green and Green+ environments compared with scores obtained when working in a Conventional environment.

I'm incorporating some of these concepts into my tiny house design e.g. a (truly ingenious design using mirrors!) terrarium and an hinoki ofuro, together with natural daylighting.
A poster called mantesso offered up this interesting paper: Here's the original study from NASA, Interior Landscape plants for indoor air pollution abatement :

When I flew into Heathrow last year, I was amazed by how visible the pollution was- over central London, there were no clouds (there were clouds around the outskirts) but this vague, blue haze was quite noticeable.Although compared to Shanghai, London is really clean, if you live in Shanghai you keep your windows permanently shut and run an air purifier 24/7: http://aqicn.org/city/shanghai/
> I'd recommend anyone living in a city to invest in a good air purifier from BlueAir or IQAir (if you can afford it).

Also basil plants are a natural mosquito repellent, might not be an issue in the UK though.
⬐ leonroyGood info. I have a Peace Lily in pretty much every room except the kids which has an Areca Palm (non-toxic).They do sod all for my pollen allergies - only an air purifier has brought it under control (anti-histamine free now).
One thing which did dismay me is just how baffled IQAir/BlueAir were when I asked if I can recycle the filter media or if they are biodegradeable.
If you are in China checkout SmartAir, clever startup which is blowing up the air purifier market (in a good way): http://smartairfilters.com/en/

⬐ mantessoVery interesting. Here's the original study from NASA, Interior Landscape plants for indoor air pollution abatement : http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/1993007...⬐ internautThat's a great paper. Several assumptions I had are confirmed after looking through it such as the importance of countering off-gassing. I don't think people are generally aware of this, they just sort of assume it's a solved problem or a diminutive one. Even natural materials like wood will release formaldehyde.For a small space having good air quality is very important, I plan to install a selection of plants and rig them up as dual purpose air purifiers as shown in the study, with emphasis on the kitchen, bathroom and bedroom.

It's not expensive and it'll pay for itself many times over with better health! Programmers take note! It is easier for your brain to work if it has a nice supply of oxygen. Rocket science I know. NASA science at any rate.
In general society (opinion incoming) has not paid much attention to closed loop systems in the way we ought to (see no evidence the Slingshot scales up). Especially as a way to introduce antifragility. A house in a truly futuristic suburb would recycle heat from water and reliably convert all black/grey water back into distilled water for household use while using the biomass to power the operation. Throw in autonomous air vehicles and ubiquitous net reach from Google blimps and I'd really feel like I'm living in the future. What is more, with houses spread out (side affect of self driving things on land prices), not laying cables/water/sewer lines and not maintaining roads anymore it would appear that it could be a much more economical future. Without cracking closed loop systems it is out of reach. Google Net Blimps, renewable energy, even autonomous vehicles seem like much more tractable problems in comparison despite water filtration seeming simpler.
