Biochemist Creates CO2-Eating Light That Runs On Algae 121

An anonymous reader writes "Biochemist Pierre Calleja has a solution to reducing carbon emissions that doesn't require us to cut back on our use of carbon-producing devices. Calleja has developed a lighting system that requires no electricity for power. Instead it draws CO2 from the atmosphere and uses it to produce light as well as oxygen as a byproduct. The key ingredient to this eco-friendly light? Algae. Certain types of algae can feed off of organic carbon as well as sunlight, and in the process produce carbohydrate energy for themselves as well as oxygen as a waste product. Cajella's lamps consist of algae-filled water along with a light and battery system. During the day the algae produce energy from sunlight that is then stored in the batteries. Then at night the energy is used to power the light. However, as the algae can also produce energy from carbon, sunlight isn't required for the process to work. That means such lights can be placed where there is no natural light and the air will effectively be cleaned on a daily basis."

    CO2 + Light = Algae

    CO2 + Algae = Light

    Even better

    Light - Algae = - CO2

    a cheap way to produce antimatter!

    Your equation requires we first have negative algae.

    HA! take that climate change deniers!

    CO2 + Light = Algae
    Light = CO2 + Algae
    CO2 + CO2 + Algae = Algae
    2CO2 = Algae - Algae
    2CO2 = 0
    CO2 = 0

    therefore, CO2 kills everything...

    Good math, bad conclusion. This proves that CO2 doesn't exist! Just wait till Fox catches wind of this!

    Forgive them, the light from these bacteria is really bad. They could not read the news scrolls well, and had to touch-type.

    The thing, as described in the text, violates the first law of thermodynamics.

    The first law of thermodynamics is a universal law. Universal laws violate US sovereignty.

    Yup. It's annoying. The current generation of video producers are afflicted with the same behavior we saw in the early years of the web. Remember when people used the now infamous "blink" tag? Yah! It was a real treat to load a page with 20 blinking links. And this behavior was carried on with animated gifs. I remember opening pages that had lists with each list item bulleted with an animated gif; eg, a spinning ball or star, or a flashing diamond, etc. The next "craze" was to do all sorts of stuff with flash. I'm amazed how many sites are still doing all their nav in flash. The most recent bane to web design is jQuery. Take a look at the source of some pages once. It's astonishing just how many jQuery scripts are being used on some pages.

    [begin rant] Well, now video producers are going through the same thing. It's cool to video the person talking, but they're looking somewhere else entirely. Or they zoom on the person's eye or hands or mouth while the person is talking. Real cool! I know that always stimulates my interest.[/sarcasm]

    Now they're going absolutely freaking nuts using zooming in then out and back in, fast motion to slow back to fast, strobing, flashing, blurring, jerky images, a series of 30 images within 2 secs, etc. And NONE of the programs or ads using these effects contain ANY worthwhile information.

    I was always amused by the Ford truck commercials and just how juvenile and primitive they were. All big, block letters sliding around the screen. Brilliant! I swear a person has to be functioning full-time with their lizard brain to respond to a commercial like that.

    If I should happen to meet one of these video producers, I just might club him/her senseless. Then ask, "How's THAT for a special effect?"[/end rant]

    Aw nuts! I forgot to take my meds again. Excuse me. I have to go.
