RE: Glowee - Bio-inspired solutions: Bacteria-alternative source of light

in #steemhunt • 7 years ago

During my childhood days, I got my senses first into incandescent bulb which was emitting very yellowish light. They said it consumes too much electricity but it was cheaper than flourescent lamp which emits near to daylight effect. Nowadays we have LED. This Glowee may not totally replace home and office lightings because of its color (but who knows, someone may discover turning its color into daylight) though it will definitely help the consumers and the environment if its existence is established in the market globally.

    I've just found the video and added it into the post where Glowee founder, Sandra Rey, tells us (beginning at 5th min.) about opportunities that might allow us to add a switch into this material to turn-on the light only at night & to change the colour of it.
    Also I wanna add that just as in case of your post about "Paper bag vs. Plastic Pag", I'm not sure this as they called it "Pollution-free light" is really waste-free. & I'm not the only one (Edith Widder):

    To get the bacteria to continue working for more than a few days requires adding extra nutrients and removing waste products, she says. “If you do the math, it doesn't make sense, especially when you factor in how incredibly efficient LED lighting has become.”source.

    And what will then happen with these waste products?

      I wonder what waste products Eddith Widder is referring to because there is nothing mentioned on the article. If those are waste products from the sources of bacteria like jelly fish then I think there should be no problem.I am not a scientist so I just talk as layman - the wastes products will just be disposed like how jelly fish does it.

      Also,

      Glowee is undeterred. Having adjusted the make-up of its gel, it is now genetically engineering the bacteria. Rey says her team is developing a molecular switch that will activate the bioluminescence only at night. This will let the bacteria save energy during the day and make the nutrients last longer.

      The team also plans to make the bacteria glow brighter and survive temperature fluctuations of up to 20 °C. Rey says the company will launch a commercial product in 2017 that lasts a month.

      Solutions exist in nature, says Rey. “Now that we have the tools to copy them, we can build far more sustainable processes and products.”

      Just like any inventions, hurdles will come along as Rey outlined in her video. But no breakthroughs came easy.

      I guess that bacteria eat something (nutrients) & excrete something (byproducts) - waste products (so if we just put bacteria (with nutrients) into a container and leave it on the street signs then the population of these bacteria will die because of their own waste products which they can not utilize anymore & supply of nutrients is limited) which that woman was referring to. But I'm pretty sure there should be a way to utilize them for something useful. Maybe even to turn these waste products into nutrients (he he). that would be really cool )

        Well, yes. Many waste products are known to be utilized as fertilizers. Maybe our researchers can find ways to do the same with bacteria wastes.
