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

today my best friend asked me “why cinderella’s shoe fell off if it fit her perfectly”
In the original story the prince ordered one of his servants to put liquid tar on the staircase to stop her from running away. The shoe got stuck on the tar.
That is a liiiiittle bit creepy
LET ME TELL YOU ABOUT THE BROTHERS GRIMM FAIRYTALES HONEY
There are three things that the Harry Potter fandom seems to universally agree upon:
1. Umbridge is awful
2. Maggie Smith is a perfect Professor McGonagall
3. Everyone should be at least slightly bothered by DID YOU PUT YOUR NAME IN THE GOBLET OF FIRE?!?!?!?!?!?!?!?!?!?!!
4. book ginny is 100 times better than movie ginny
5. where the fuck was peeves
6. Voldemort was fucking useless

If Lupita is the real life Disney Princess, can Jennifer be the real life quirky side kick?
This is the best one I’ve seen.
I know that somewhere upon the grass, her dragons hatched, and so did she. I know she is proud. How not? What else was left her but pride? I know she is strong. How not? The Dothraki despise weakness. If Daenerys had been weak, she would have perished with Viserys. I know she is fierce. Astapor, Yunkai and Meereen are proof enough of that. She has survived assassins and conspiracies and fell sorceries, grieved for a brother and a husband and a son, trod the cities of the slavers to dust beneath her dainty sandalled feet.
