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!

I will donate $1 (USD) per 5 notes towards the ‘American Foundation for Suicide Prevention’ 

(I’m doing 1:5 ratio as I don’t make substantial amount of money where I can up the ratio)

No rules. Ends August 26th, 2014.

Your bottled water habit is sucking California dry

If you’re reading this, chances are very high that your home has at least one — and maybe more! — magic appliance that produces clean water suitable for drinking. That’s one reason to avoid paying for bottled water.

Another reason? There’s a good chance the water you’re buying at the supermarket was bottled in California, a state currently enduring a severe drought.

Turn on the tap instead Follow micdotcom

EVERYONE PLEASE AT LEAST TAKE A QUICK SECOND TO LOOK AT THIS

BECAUSE IT IS EFFECTING THE EXACT AREA I LIVE IN

Lots of people believe bottled water is safer and cleaner than tap water, when in reality there’s no evidence proving such a thing.

Penn & Teller’s Bullshit!: Bottled Water segment, gives a very good and thorough summary of the bottled water culture https://www.youtube.com/watch?v=MHx6BX3HZJc

You want better water? Buy a Zero filter. SRSLY. Stop buying bottled if possible. You need water with you? Get reusable acrylic or glass water bottles (wrapped in a silicon sleeve) and fill it up from your filter pitcher. SAVE MONEY, SAVE MY STATE

This is all incredibly important, some cities have as little as 60 -120 days left.  Try using a refillable water container, and if you’re a California resident, make sure to report water waste in public spaces.

Also, maybe take a second and sign the petition to stop a giant Slip n’ slide from being built in Los Angeles. Priorities.

Discworld + Tumblr posts (meta edition)

Seeing as how the Discworld fandom comes up with great posts all the time, they needed their own post to themselves :)
