I cannot stop laughing. omg.

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
do you ever just have that sobering realization of like, “holy shit, i exist. i am a biological being of the universe, 15 billion years of evolution from the big bang and here i am. a chemical structure of atoms and molecules that once had their birth in the centre of stars, i am the universe looking back upon itself. i am the universe.”
and then have trouble going to work or taking life seriously at all haha
Wow this .gif is so good
This gif is the highest quality gif I have ever seen everx
Probably the best gif I’ve ever seen.
i hope kesha’s return includes her taking down perez hilton but with the utmost class and dignity and a lil bit of crazy bitch
