  • 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
