Bailey Jay, Complex, and Crazy: lebanon-hangover: partlysmith: gelunnucifera: callan-the-misandrist: positive-press-daily: 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.) solar punk sensibilities with cyber punk aesthetic Swamplamp

Pleeeeeeeeeze let me change the light bulb! Can I? Can 1? Huh? Huh? Can I? Pleeeeeeze please, please, please Poodle: I'll just blow in the Border Collie's ear and he'll do it. By the time he finishes rewiring the house, my nails will be dry ◆ The Cat's Answer: Dogs do not change ligh to take advantage of the German Shepherd: I'lI change it as soon as I've led these people from the dark, check to make I'll just pop it in while I'm sure I haven't missed bouncing off the walls any, and make just one and furniture. more perimeter patrol to Old English Sheep e see that no one has tried Dog: Light bulb? I'm situation. Jack Russell Terrier: bulbs. People change light bulbs. So, the real question is: How long will it be before I carn expect some light, some dinner, and a massage? 28 July 9, 2011 Funny
