GREEN BAY, Wis. (WBAY) - The sun doesn’t just keep us warm and help us find our way during the day. Enough sunlight hits the Earth in one hour to meet the human world’s energy needs for an entire year.

Talk about a wasted opportunity.

Solar cells can create energy from the sun’s light but they’re not very efficient, converting maybe 25% of it into electricity. A Purdue biophysicist, Yulia Pushkar, says nature has already solved this problem: Plants have been converting solar rays into energy since before animals walked the earth.

Brad explains how she’s harnessing the energy of “artificial photosynthesis” in 3 BRILLIANT -- some would say “BRIGHT” -- MINUTES!
