Well this is fun for me
What a great apartment this would make… (via Photographs taken inside of instruments » Lost At E Minor: For creative people)
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.)
Fellow geeks - Oxford University Press is opening up all of its databases to the public in honor of National Library Week, until Sunday, 4/19. It’s a great opportunity to check out scholarship and research you would normally have to get through your library or university, or pay for a subscription to.
A list of sites is here:
The credentials are: libraryweek / libraryweek and will work with any of OUP’s online sites listed at the link above. (Remember, if you’re being prompted for an email address, you’re signing in at the wrong place!)
Here are some geeky titles you may want to check out:
- Science Fiction: A Very Short Introduction
- The Superhero Reader
- Gothic Science Fiction 1980–2010
- Maps of Utopia: H. G. Wells, Modernity and the End of Culture

To celebrate National Library Week (13-19 April), Oxford University Press is making all of its online products free to access in the United States for the week!
Libraries are a vital part of many communities, whether for universities, towns, corporations, or hospitals, and this is our…
As of now and I assume until Friday when the next episode airs, this link will show you the Kids in the Hall reunion on “Spun Out”. (It’s not geoblocked, so if you’re in the US you can still watch it. Canadians are nicer than we are, guys.)
@Mark_DMcKinney’s playing his goth character as Darrill is breathtakingly hilarious. And Kevin’s character is a riff on Dean, his “King of Empty Promises”. This is fucking delightful.
