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

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.
