Could algae be the future of green energy?
The main gas emitted by cars — carbon dioxide, or CO2 — is one of the major green house gasses, which contributes global warming and climate change. What if that CO2 exhaust was reused into something much more beneficial, such as powering street lamps?
The French bio-chemist Pierre Calleja invented carbon capture lamp that is designed to run without electricity by using the carbon emissions it gobbles up from passing cars.
Calleia is the CEO and founder of Fermentalg, a company that focuses on working with microalgae and fermentation processes, he and his team developed his lamp to double as a habitat for microalgae, which adsorbs solar energy and consumed carbon dioxide. The team installed one of these lamps in a parking garage in Bordeaux, France to exhibit the lamp’s ability to continuously illuminate places, even in unlit places.
These lights could help against rising carbon emissions and climate change.
