Algae Bulb lights up with the power of biological and chemical reactions to provide light almost equal to that from LEDs. Speaking from the concept view, that’s a very interesting theory. Basically, the bulb is a container for algae, where the power of the micro-organism is extracted to act as a power source that can light up LEDs for a few hours.
The concept by Gyula Bodonyi includes an air compressor, tank and hydrophobic material working with the algae to provide light. The air compressor is powered by electricity and we can only assume it takes more power than an LED to provide light for a limited time and in a complex setting.
