Bacteria Can Be Sustainable Source of City Lighting

Science is always looking for smart ways to make our planet more sustainable, and solutions for homes and cities are also part of that.

This time, the novelty in sustainable research came with the French startup Glowee, Whose goal is that we no longer need electricity to produce light.

And how does she do it? Through a study of bacteria that have bioluminescence-the ability to shine in the dark. Keep following and learn more about the work:

Founded in 2013, Glowee has emerged to offer live and sustainable lighting raw materials. With this, he began to develop a research work with bacteria that do not need external energy to produce light, cultivating them in a kind of capsule that can be customized in different formats-such as for shop fronts, for example.

With a whole business model based on product reuse and treatment and low carbon emissions, Glowee can greatly reduce its impact on the environment. In this way, the company’s goal is to use bacteria as an alternative source of energy for city lighting by applying the technology where electricity is replaceable.

What motivates Glowee with this innovation is to reduce the 19% rate of electricity consumption in the world dedicated to artificial lighting, which is responsible for 5% of greenhouse gas emissions, as well as providing light to people and places that Suffer from the lack of electricity.

This new light source has several benefits for the environment. Because bacteria grow exponentially and without the need for a large lighting infrastructure, the capsules used for growth require only simple production processes, such as3D modeling and printing.

Moreover, the sustainability of the whole process is undeniable. Because it is a cold light and less intense, all the energy produced is used in the production process itself and, with it, it is possible to limit the effects of visual and luminous pollution in the environment.

The startup participated in a collective financing in 2015, in which it raised almost 50 thousand euros. It is currently pursuing investment and is working to expand the light intensity produced by its bacterial cultures, as well as its useful life, which for the moment is limited to three days of light.

The technology is truly amazing, but it is not yet available for marketing. However, there are already excellent alternatives to reduce the environmental impacts of lighting. One of them are LED lights via Hetongdiy.com, which have no mercury in their composition and last much longer than incandescent and fluorescent lamps.
