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
"What is shipping?"
Finally someone said that. #lol #lmfao #humor #funny #fun #disney #frozen
You cannot buy electronics with food stamps. You cannot buy cigarettes with food stamps. You cannot buy pet food with food stamps. You cannot withdraw money with an EBT card (food stamps).
Do you know what else you can’t buy with food stamps? Shampoo, soap, laundry detergent, toilet paper, paper towels, tissues, tinfoil, plastic sandwich bags, toothpaste, cleaning products, tampons, pads, over the counter medications (such as Tylenol, Ibuprofen, etc.), and anything else you can think of that you cannot physically ingest for nutritional purposes.
Do you know what you can buy with food stamps? Food.
Do you know what it’s like to scrounge for change to buy non-edible necessities, use a credit card and EBT card (food stamps) during the same transaction, and then have the person in line behind you judge you for buying the ingredients to make a birthday cake?
People who disseminate false information about food stamps have never had to use food stamps.
Re blogging for commentary mostly. How are people so ignorant? The ONLY thing you can buy w food stamps is fucking FOOD.
The fact that these “reporters” seem so offended that those who are bad off enough needing to rely on food stamps dare to try and enjoy life..
A pet to combat depression, Disneyland to give the kids a glimmer of hope, Vegas in an attempt to escape the low end rung of poverty. Condemning the poor for doing all the things these well-paid job holders can do without going hungry.
Oh no. Big bad poor folk. They can’t ever be happy.
Lots and lots and lots of practice
(years tbh), it was my weakest point….! I mentioned this before but Black2Sun has a wonderful resource blog, this is the hand tag so check it out.
Signal boosting in case anyone needed to know this.
This is informative as heck. Show this to everyone!
This is actually some great info! Why can’t they teach this kind of thing in school??
Wow, I’ve taken health and sex ed three times during my educational process and never learned any of this. Thanks.
Definitely some important information here!
this is supa awesome. i do think it should be noted that side effects of EC *really* vary. when I took EC I didn’t have any symptoms whatsoever.
I DON’T KNOW HOW I GOT IN HERE
AND NOW I CANNOT GET OUT
DO SOMETHING ABOUT THIS
If you always help the kitten out of the cup they’ll never learn not to get into small cups in the first place
I’VE LEARNED MY LESSON HUMAN

Do not hate homosexuals, bisexuals, asexuals, ect
But do not hate heterosexuals.
Do not hate trans*gender, agender, non-binary people
But do not hate cissexuals.
Do not hate people of color

Hatred only breeds more hatred. Is it that hard to understand?
This needs more attention than it’s gotten.

I’m not sure why I just found out about this but….amazing! So fast and simple!
oh my shit ♥
This is lovely! I’d also like to recommend Design Seeds for colour schemes.
hellllooo help for electronic illustration project
This is for you, Nose Anon!
Honestly, I suck at tutorials. I really, really do. This is my first one since…forever ago [and back then I sucked worse so that doesn’t even count] and it was kind of just a quick “Let’s see what I DO know and see if I have any idea how to convey that coherently, or maybe it’ll just explode in my face”
SO HERE YOU GO! All I know about drawing noses freehand in an almost-tutorial…ish…thing. Maybe.
