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]

NEAT

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.)

SCIENCE!

LOL YES.

I was afraid when they killed [Brown]. I was scared about my big brother, Taujh, ’cuz he’s around 18. So I was kind of scared for him because he wears hoodies and stuff.

10 year old Antonio Jones from Ferguson explains his fears for his older brother. 

Even at the age of 10 this boy recognizes that wearing a hoodie and being black is enough to make his brother an extremely likely target. These are the concerns of black children in the U.S, these are their fears and this is the reality they face.

white/non-black privilege is not having to worry about wearing a hoodie outside…

Saving Face (2012), acid attacks on women in Pakistan

Meanwhile, in America, feminists are complaining about how dress codes are oppressive.

You idiots have never experienced oppression, and pray you never do, because this is what it looks like.

As a South Asian American feminist, let me remind everyone that oppression is not a competition.

Just because we fight one type of sexism doesn’t mean we don’t care about other instances of sexism that don’t affect us directly in our day to day lives.

My heart goes out to this woman and the hundreds of other victims like her. I want to educate people about these kinds of incidents. I support organizations that help women like this.

You may think that dress code issues are trivial, but they are related to a larger issue of women’s bodily autonomy, which affects women’s health and safety.

So please, let’s try to bring awareness and bring about change instead of insulting entire groups of people because they are facing issues that are less scary than the one presented.

oppression is not a competition

thank you so much for this wording
