Earth radiates millions of gigawatts of energy every second, which dissipates in the environment in vain. Now, the researchers at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have figured out a method to harvest electricity from Earth’s excess heat via a process called quantum tunneling.

This proof of concept model opens up new avenues of power generation and can be particularly useful in solar panels that currently tap a small percentage of energy from the visible light spectrum, writes Inhabitat.

The system is still in the development stage but augurs a bright future where millions of small electricity harvesting devices will ramp up power generation efforts globally, notes Science Alert
