Solar energy: Dyes help harvest lightWed, 30 Jul 2014 10:40:38 EDT
A new dye-sensitized solar cell absorbs a broad range of visible and infrared wavelengths. Dye-sensitized solar cells rely on dyes that absorb light to mobilize a current of electrons and are a promising source of clean energy. Scientists have now developed zinc porphyrin dyes that harvest light in both the visible and near-infrared parts of the spectrum. Superman's solar-powered feats break a fundamental law of physicsWed, 30 Jul 2014 09:38:37 EDT
It goes without saying that Superman can accomplish some pretty spectacular feats. But according to students, the Man of Steel actually achieves the impossible--by breaking the fundamental physics law of conservation of energy. Worldwide water shortage by 2040Tue, 29 Jul 2014 09:31:12 EDT
Water is used around the world for the production of electricity, but new research results show that there will not be enough water in the world to meet demand by 2040 if the energy and power situation does not improve before then. Steam energy from the sun: New spongelike structure converts solar energy into steamThu, 24 Jul 2014 21:39:57 EDT
A new material structure generates steam by soaking up the sun. The structure -- a layer of graphite flakes and an underlying carbon foam -- is a porous, insulating material structure that floats on water. When sunlight hits the structure's surface, it creates a hotspot in the graphite, drawing water up through the material's pores, where it evaporates as steam. The brighter the light, the more steam is generated. How to power California with wind, water and sunThu, 24 Jul 2014 14:43:16 EDT
New research outlines the path to a possible future for California in which renewable energy creates a healthier environment, generates jobs and stabilizes energy prices.
