Eco Factor: Concept coffee table harvests dirt power to recharge portable gadgets.
The VoltPot by designers at Nectar Design is a unique coffee table that doubles as an indoor planter and triples as a gadget charger. The concept table puts the environment to work indoors by harvesting the power of dirt using a built-in microbial fuel cell to provide enough energy to charge your portable gadgets.
The onboard fuel cell is able to utilize the metabolic energy of microbes present in soil and convert it directly to electrical energy at a continuous rate. The designers state that harvesting about 1W of power per cubic meter of soil is achievable at the moment, but test conditions have shown that 10 times that amount is possible.
