The Future of Light is Living

The Future of Light is Living



Light pollution is an issue that is happening
in more than 99% of Earth's inhabitants. The intensity of LEDs is so high it has increased
lighting pollution. We need to find alternative solutions that
are both more respectful for the environment and also offer a new energy sobriety. We use a reaction called bioluminescence which is the ability a lot of organisms in
nature have to produce light like fireflies or glowworms, but also 80%
of marine organisms. So we use this chemical reaction to produce
a biological source of light. I was fascinated by the fact that it's so
simple, it exists in nature, it works pretty well, so why not just translate that into a product? In the sea something that is very common is
not extraordinary and so you have to understand that if it's
common it means that it is efficient and behind us we have 3.8 billion years of
research and development through evolution in nature to find those
efficient solutions like bioluminescence. So the first goal behind Glowee is really
to use a growing raw material to replace these lighting systems. Our job today is to identify the best bacteria
that are able to produce the best bioluminescence. Once we have them we work with them in labs,
we engineer them to make them more efficient in terms of intensity, in terms of stability
over time, in terms of temperature resilience and when we have that we can grow those bacteria, mix them with a nutritive medium and then
find the best conditions for them to grow. The type of water is the first variable, the
temperature is also important, the way we feed them is very important. The reaction of bioluminescence needs oxygen
to produce light. When you switch on the oxygen, the light switches
on. The overall goal of playing with the different
settings is first improving intensity, second in improving stability over time to
make the bacteria light as long as possible to make them be fed as less as possible to
improve in terms of cost efficiency. Our goal is to go outdoors, so we need bacteria
to resist at less than 15 degrees (Celsius) and more than 30 degrees to cover the most
geographies as possible. Once we have all the recipes we can put this
raw material into different shapes to make lighting systems happen. Today we don't really face nature in our daily
lives as citizens living in cities and this connection humans have to nature
is just essential for our wellbeing. We figured out that this light is very hypnotic,
it's very soothing and so it really brings a wellbeing feeling so we've designed the 'Glowzen Room' which
is a biophilic experience of bioluminescence. The goal is to fully relax, to reconnect to
nature. So when you look at this soft light you can
look at it without getting your eyes tired which is something that is very unique because
it never happens with electrical lighting. As you're in darkness and your eyes get used
to darkness progressively, then your brain focuses on little details
that you see and those little details are very simple things flowers, leaves, a tree. When your brain thinks about these simple
things it just doesn't think about what you forgot to do yesterday. Using a biological material to produce light
changes all the value chain of lighting from producing it because we can grow light, to using it because it's not an object like a bulb, but you can really play with the raw material,
it can take a lot of shapes. It can also really change the way a building
looks like, the way signage looks like to really give more design
possibilities to it. So we're gonna start with urban furniture,
signage, but the more time is going, the more we think that we can really rethink
the whole way we light our cities, so tomorrow maybe there are no lamp posts
but just different ways of lighting the areas because it's gonna be more pedestrian, there's
going to be less cars. The interesting thing is that light won't
be a one-shot use. When there is a problem, or no more bacteria,
or no more light we can just restart a little culture of bacteria
and then a few hours later you will have the system working again. In the societies we live in we can not just
switch off all the lights. It can be used to illuminate, for security
purposes, to enhance something, to give visibility. We need to find the best energy sources at
the best place so that we create this mix of energy to really
have positive effect. It's really interesting in terms of how to
think of the cities of tomorrow

  1. We're introducing the first episode of our new series, Second Nature. Have you noticed light pollution to be a problem where you live?

  2. Is this b for real with light pollution Is a problem I would never invest in this garbage idea. I reinvented neon lights but there alive and a pain in the ass to keep alive

  3. If I needed to talk to someone at Bloomberg about an invention that saves lives and is not yet being produced, how would I do that?

  4. Uuum, long term environmental effects of bringing bacteria that stay deep in the ocean to land in large quantities?

  5. Really hope this bioluminescent lighting makes it past the research phase and get widespread adoption, either that or the way streetlights are managed in Hawaii becomes the norm, kind of miss being able to see the stars at night

  6. It's a shame that people are so afraid of the dark. You can see quite well after a few minutes in the dark but most people never try.

  7. Wat if that bio watever is harmful once the tube is destroyed, think o global warming mannn … air pollution abuse is damn imp, not light abuse thats dumb asf

  8. Obviously instead they should engineer trees with the firefly gene. No maintenance required. Already been done in other plants.

  9. So other than being "all natural", what's the advantage? I'm sure the amount of energy required to create and maintain these organisms are about the same, if not more, than the amount of energy required to create a light bulb and generate the electricity… or maybe I'm wrong… it wasn't clear in this video.

  10. It's impressive they can generate this much light already, but it's still a long way from human use.

    Our eyes are most comfortable when receiving "sunlight." That is, natural light with all the colours in the wavelength spectrum. That is actually very difficult to replicate. If you ever see fluorescent lights that feels uncomfortable to look at, or makes you feel like you are in a morgue, that's because the wavelength is off the mark.

    Right now, it only looks cool, but it takes more to scale.

  11. Come on people! Seriously? Light pollution? Look, you are going to make this crap and it is going to cause other problems!

  12. The color and mellow intensity of bioluminescence is absolutely beautiful, but the variety we have in just the color temperature alone in current lighting is much more desirable. Different color temperatures affect mood and emotion.

  13. We tried exactly that in a small startup. Her claims are ridiculous – scam alert for investors. You can imagine how dark these tubes are when you look at the graininess of the video footage. Even when you could enhance the light production by a factor of 10 large tubes wouldn't produce as much light as an ordinary light bulb.

  14. "scientists were so preoccupied with whether they could, they didn't stop to think if they should" – Ian Malcolm

  15. I'm not knocking bio-luminescent sources, but light pollution is a question of concentrated intensity, not source of light.

  16. Light pollution is light pollution no matter what source emits the light. If these GMO bugs find a way to survive on their own, then we'll have a lot more light pollution.
