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.)
When I look down at this golden statue, may it remind me and every little child that no matter where you’re from, your dreams are valid. Thank you.
you can preach about slut-shaming all you want, but you can’t deny there’s something very wrong with 13 and 14-year old girls going out in skirts and dresses so short they barely cover their asses and shirts with necklines so low they show off cleave they haven’t got yet, drinking and even smoking and hooking up with guys before they even have a substantial knowledge of how sex and sexual relationships work.
Thank YOU HOLY SHIT

- desperately wants to remain single for as long as possible
I am both.
