French biochemist Pierre Calleja has invented an innovative algae lamp, and it’s claimed to absorb 200-times more CO2 than trees, at the rate of 1-ton annually, or what a tree absorbs over its entire lifetime. Pierre has basically developed a lighting system that requires no electricity for power. Instead, it draws carbon dioxide from the atmosphere and uses it to produce light as well as oxygen as a byproduct. The key ingredient? Algae. There are certain types of algae that can feed off of organic carbon as well as sunlight, and in the process produce carbohydrate energy for themselves as well as oxygen as a waste product. According to Geek.com, “Cajella’s lamps consist of algae-filled water along with a light and battery system. During the day the algae produce energy from sunlight that is then stored in the batteries. Then at night the energy is used to power the light. However, as the algae can also produce energy from carbon, sunlight isn’t required for the process to work. That means such lights can be placed where there is no natural light and the air will effectively be cleaned on a daily basis.”
