Scientists have been searching for clean power sources for years, and now they may have discovered a game-changing solution. In a recent study published in Energies, researchers successfully created a carbon-negative power source using algae. By leveraging photosynthesis, the process converts carbon dioxide into energy, producing only water as a byproduct. This revolutionary technology captures electrons from algae during photosynthesis to generate electricity, paving the way for sustainable and environmentally friendly power production. While scaling up to power entire cities poses a challenge, scientists are optimistic that with further research and development, carbon-negative power could significantly reduce carbon emissions. Unlike current power systems that rely on hazardous materials, this innovative approach offers a safe and efficient alternative. This breakthrough could potentially transform the future of energy production, offering a promising solution to combat climate change.
