> isn't this expensive to run

comparing lighting to the consumption of a fridge, which is one of the most energy intensive appliances in an average house, is kinda ridiculous. Its like saying your lawn mower energy use is just fine because it consumes the same as your SUV.

Tl;dr: 2kwh per day for a light is a LOT. A standard led light would consume about 5% of that.

Every few years some company/research lab will claim they have a technology that’ll simulate sunlight coming through a window, but it still isn’t something one can buy. The moment we can buy eg a 3ft by 1ft panel that we can just mount on a wall and feels like an actual sunlit window for a few thousands dollars or so, interior design is likely going to get radically different. (And that’s not to mention the sci-fi dr…

When we were building out an office that only had a few windows I went looking for, and found one of these. Unfortunately it’s $60k instead of $2k. According to reviewers that saw it, it’s amazing.

Apparently it uses some nanoscale material that produces (mimics?) Rayleigh scattering.

This is great to see, for I've been wondering lately why being outdoors is more pleasant (in clement weather) than indoors. Is it the unpredictability? the humidity? the noises? the sunlight? In that same vein, I've wondered how to simulate outdoor conditions inside, especially something approximating more light, in part because I think a family-member is mildly susceptible to seasonal affective disorder. I can't wai…

I’ve also been wondering this lately. In particular if I’m feeling slightly ill, I feel much better outdoors. At least in my experience, it isn’t necessarily sunlight as I think it’s also better at night. And it isn’t super “fresh” air or hearing birdsong or the wind rustling through trees (positive things I associate with being outdoors) as I live in a city. I hadn’t thought about humidity. Currently my best guesses are:

- a correlation between being outdoors and stood up and moving

- colder temperature (but I guess in the summer when it’s not stifling it can be preferable to be out so maybe this is wrong)

- some psychological/placebo effect

- less CO2 in the air. I can’t really put any numbers to this hypothesis as I don’t have a meter.

Obligatory Tom Scott video on indoor CO2 levels:

(or the studies themselves https://www.gwern.net/docs/co2/2015-stafford.pdf and others)

I.e. I think air quality is likely a big factor. When it's windy and I get good airflow through my room it doesn't feel as different from outside. It's probably not only CO2, but also dust, VOCs, funghi, microorganisms, etc.

I’ve got 5 of these in my office. https://www.superbrightleds.com/moreinfo/industrial-led-ligh....

They are fantastic. I have several more of the longer fluorescent replacements in my wood shop. More light is magnificently better for energy and productivity in pretty much all environments.

I would still prefer skylights to bulbs, but these are a good solution for dark rooms.

Many offices, mostly in places like Amsterdam, Paris etc. in art-deco building, take pride in the amount of natural light they're pumping in the office. With mirrors and sunroofs (with sails as shade) and a few plants, you can really give a beautiful, open air feeling to your office.

This, feels like crutches.

edit: there is something to be said about starting an hour earlier and finishing an hour earlier if the sunset is early. It may be a good idea to live with the natural rhythm of the earth rather than some clock on the wall.

The second sentence of the article explains that he's trying to figure this out because the sun sets in Boston at 4:15 PM now.

When it gets dark by 3:30pm and there’s so much cloud cover it never gets past dusk, you’ll appreciate the crutches. Biggest downside to living in seattle atm.

My guess is more sunlight, less CO2.
