Why is it in the news?

• Recently, scientists have developed a new fuel cell, claiming it can harvest energy from microbes (bacteria) living in the soil.

More about the news

• The soil-powered fuel cell is an innovative technology designed to generate power without relying on traditional chemicals. Instead, it harnesses energy from microbes present in the soil during the decomposition of organic matter.
• Microbes release electrons as a natural byproduct during the breakdown of organic matter in the soil.
• These released electrons create an electric circuit by flowing from the anode to the cathode, thereby generating power.
• One of the key features of this technology is its potential to last indefinitely.
• As long as there is organic carbon in the soil for microbes to decompose, the soil-powered fuel cell can continue generating electricity. This sustainability factor makes it an attractive and renewable energy solution.

Significance and its applications:

• The technology holds promise for applications in green infrastructure, enhancing the sustainability of various projects.
• In precision agriculture, where energy needs are diverse, this technology could find applications for sustainable power generation.
• The soil-powered fuel cell serves as a sustainable and renewable alternative to traditional batteries.
• It eliminates the use of toxic and flammable chemicals found in conventional batteries.
• By avoiding toxic chemical leaching into the ground, it addresses environmental concerns associated with traditional battery disposal.
• By providing a sustainable alternative to traditional batteries, the soil-powered fuel cell contributes to the reduction of electronic waste.
• The avoidance of toxic chemical leaching further establishes it as an eco-friendly energy generation solution.
