This lamp absorbs 150 times more CO2 than a tree
It’s still in the “so crazy it just might work” stage, but these microalgae-powered lamps, invented by French biochemist Pierre Calleja, could absorb a ton of carbon from the air every year. That’s as much as 150 to 200 trees. [x]
YOU DON’T UNDERSTAND. This is ingenious.
The design is a light bulb surrounded by a glass casing. The glass is filled with (water based) media and microalgae. The top is permeable to gasses so that gas exchange can occur. All of the wiring is linked to the grid underground.
Since the light source is inside, it gets scattered and “dimmed” by the water and algae. This makes it less glaringly bright and scatters the light wider, which is good for a street light. It is not longer white light as well, which helps make it easier on the eyes while still providing light.
At the same time, it provides the light for photosynthesis in the algae, so they are continuously exchanging CO2 for O2, not just in the day. It also provides a source of heat, which helps keep the algae from going dormant during cold weather (as in the snowy picture above).
And notice how I did not specify permeability - that’s because NOx’s (NO and NO2) are also permeable and can be used as nitrogen sources to microalgae. In fact, algae are relatively low maintenance. As autotrophs, they don’t require super complex media, not does it really need to be changed/added to. (I’m actually fairly certain that there would still be algae in these tanks a year later; it may need to be cleaned or something, but there would be some living algae.)
and they’re so pretty too
we need to make this a thing
So this is cool but all I see is cities full of these and people not giving a crap about real trees anymore. Again, way cool but we tend to get lazy and rely on science to solve problems when nature could do it without any waste and fo free.
Yes the Lorax came to mind when I saw this
I don’t think so, because trees provide a lot that these don’t . People don’t only plant trees for CO2 exchanges. Most city trees are there for decoration purposes, as well as to provide shade and shelter from the elements. Things that these lights would not provide. Moreover, i think enough people know trees provide habitat for various species.
"aesthetic" is a very good word, important word. "i love the fifties." no you don’t the fifties kinda TOTALLY SUCKED for many human beings in America. "i love fifties aesthetic" well then, awesome. go you with your bright blocks of color and cute skirts and mini jackets and hair poufs.
Previous research on racial disparities has revealed that when white people see someone experiencing physical pain, they sweat more if the person is white than if the person is black.
In fact, one alarming study found that some doctors prescribe better pain medication for their white patients than black patients.
But when does this bias start? Psychologists at the University of Virginia in Charlottesville surveyed a sample of mostly white children at age five, seven, and 10. The children rated how much pain they expected two other children — one black and one white — would feel in certain situations, like biting their tongue, or hitting their head.
The five-year-olds reported that the two children would feel about the same amount of pain. But a weak racial bias emerged in the seven-year-olds, and by age 10, the children showed a “strong and reliable racial bias" in that the white child would feel more pain than the black child.
I have endometriosis, a condition that causes ridiculously painful periods, cysts, and other horrible painful side affects. Because of this I am prescribed narcotics for the pain. Or I should be.
I’d like to think the reason my PCP suddenly stopped asking if i wanted a script for Vicodin is because of the rise of prescription drug abuse.
However it’s on my chart that I NEED to have a pain medicine more power than an anti inflamatory.
That said, if I go to my gyno they give it to me without question or hesitation.
This is incredibly important.
