With that said, all these lighting systems using LED bulbs still use a huge amount of energy, which is why … [Read more...] about This tech makes sunlight more potent so normal greenhouses can grow more
This cheap mineral is making LED lighting technology far more efficient
Light-emitting diodes (LEDs) may be the most energy efficient light-generating technology we have now, but scientists have found a way to make them even more efficient. Using perovskite, a mineral found abundantly in the Earth’s mantle, as the semiconductor, the LED can produce … [Read more...] about This cheap mineral is making LED lighting technology far more efficient
