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
omg what if you made them into the SHAPE of trees
Canyon River Weyr
At the joining of three rivers…
…there was a Weyr.
In the walls of the canyon lived the dragonriders of Canyon River Weyr. This small, unusual dwelling formed when the Weyrs of Pern agreed it was a good idea to establish an overflow destination as populations grew in the decades leading up to the 8th Pass of the Red Star. Many were the voices among the Holds that questioned the return of that age-old enemy, Thread, but also many were those who believed and supported the Weyrs. Those Holds suddenly thrust under Canyon River’s authority were however divided, with some holders hanging onto their previous loyalties and not appreciating the change of leadership.
The birth of a new queen dragon on Canyon River Weyr’s sands has been a great relief to all, though many are still murmuring about what is to become of the “hematite” queen, Ziirith. Only time will tell.
And still, the Red Star drew ever closer…
Canyon River Weyr is now open for all! Come see what we have to offer and get in on the ground floor of a unique new Weyr.
