Sphagnum The moss inhibits the growth of microbes and reduces the need for chlorine in swimming pools. In New Zealand, both the species "S. cristatum" and "S. subnitens" are harvested by hand and exported worldwide for use as hanging basket liners, as a growing medium for young orchids, and mixed with other potting mixes to enhance their moisture retaining value. Peat moss is a critical element for growing mushrooms. The fungal mycelium grows in compost with a layer of peat moss on top, through which the mushrooms come out, a process called casing. Peat moss, dead or alive, is also a
Alternative fuel vehicle cells and electric motors instead of a traditional engine. Hydrogen reacts with oxygen inside the fuel cells, which produces electricity to power the motors. One primary area of research is hydrogen storage, to try to increase the range of hydrogen vehicles while reducing the weight, energy consumption, and complexity of the storage systems. Two primary methods of storage are metal hydrides and compression. Some believe that hydrogen cars will never be economically viable and that the emphasis on this technology is a diversion from the development and popularization of more efficient hybrid cars and other alternative technologies.
