A new solar technology based on tiny nano-sized antennae is capable of harvesting energy with 80% efficiency, as opposed to the 10-20% seen on commercial solar panels today. But if that isn't amazing enough for you, these new panels can even harvest energy at night, by absorbing light from the infrared region of the spectrum, which continues to residually radiate during nighttime. And even better still is that solar panels based on this technology could be manufactured even more cheaply than existing silicon-based solar panels today. Now these are innovations that Indians need to pay attention to, as they could liberate countless masses from misery, providing power 24/7.
