A new study in the American Chemical Society's journal Nano Letters says thermocells based on carbon nanotube (CNT) electrodes might eventually be used for generating electrical energy from discarded heat.
Looks a great idea, much of our energy usage is wasted as heat, recovering a portion of that could offset costs, and save money in homes. It seems the technology is already as efficient as solar power.
What do you think of this new technology?
