Gallery: New System Powers Your Home More Efficiently with Solar-Hydrog...


A professor at Duke University has developed an innovative solar energy system that powers buildings with hydrogen. The system, though it looks like a solar array, is made up of thousands of coiled copper tubes coated with a thin layer of aluminum and aluminum oxide and filled part-way with catalytic nanoparticles. A mixture of water and methanol is rushed through the tubes, and as it heats up and evaporates a catalyst is added to create hydrogen. The system is more efficient than any currently on the market, and the hydrogen created can be stored in a pressurized chamber to be used whenever needed.
