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.)

For the ppl saying “how y’all didn’t know about that “ don’t act like y’all know every damm thing because I know for a fact most people didn’t know about this 😂😂
peak comedy is when my friends who have alexa or google home are in a house that doesn’t but they forget and they just say out loud “alex, play–wait” and look confused and embarrassed it’s like they got sent back in time and i’m some humble farmer hosting them and they’re trying to adjust to the fact that I don’t have plumbing
that said I can’t pick on anyone for getting used to stuff too fast bc one time I lived without plumbing/running water for three months and one day I went into town and used a public bathroom and when i got in there and looked at the toilet I was absolutely taken aback. I was like a time traveler from the past seeing one for the first time. Bonkers.
I didn’t have AC growing up, have had it in the places I’ve been living for three years now, and my husband still comes home to find I’ve let the house get to alomst 90 because it doesn’t occur to me to turn it on.
By using a camera and computer vision software it is possible to make a fish control a robot car over land. By swimming towards an interesting object, the fish can explore the world beyond the limits of his tank. Via Studio diip

It was a Muslim who realized that light ENTERS our eyes, unlike the Greeks who thought we EMITTED rays, and so invented a camera from this discovery.
It was a Muslim who first tried to FLY in 852, even though it is the Wright Brothers who have taken the credit.
It was a Muslim by the name of Jabir ibn Hayyan who was known as the founder of modern Chemistry. He transformed alchemy into chemistry. He invented: distillation, purification, oxidation, evaporation, and filtration. He also discovered sulfuric and nitric acid.
It is a Muslim, by the name of Al-Jazari who is known as the father of robotics.
It was a Muslim who was the architect for Henry V’s castle.
It was a Muslim who invented hollow needles to suck cataracts from eyes, a technique still used today.
It was a Muslim who actually discovered inoculation, not Jenner and Pasteur to treat cowpox. The West just brought it over from Turkey
It was Muslims who contributed much to mathematics like Algebra and Trigonometry, which was imported over to Europe 300 years later to Fibonnaci and the rest.
It was Muslims who discovered that the Earth was round 500 years before Galileo did.
The list goes on………..
Just imagine a world without Muslims. Now I think you probably meant, JUST IMAGINE A WORLD WITHOUT TERRORISTS. And then I would agree, the world would definitely be a better place without those pieces of filth. But to hold a whole group responsible for the actions of a few is ignorant and racist. No one would ever expect Christians or White people to be held responsible for the acts of Timothy McVeigh (Oklahoma bombing) or Andreas Brevik (Norway killing), or the gun man that shot Congresswoman Giffords in head, wounded 12 and killed 6 people, and rightly so because they had nothing to do with those incidents! Just like the rest of the 1.5 billion Muslims have nothing to do with this incident!

Fire glass produces more heat than real wood, and also is environmentally friendly. There is no smoke, it’s odorless and doesn’t produce ash. You are able to stay toasty warm without cutting down trees and the specially formulated glass crystals give off no toxic deposit.
