Sphagnum cuspidatum moss, and to avoid contact with the moss against scraped or cut skin. The moss prefers damp conditions, and is relatively hardy in peat bogs. It does not perform as well in completed submerged conditions as it is incapable of producing sufficient amounts of chlorophyll to grow extensively, and natural causes also result in the death of new shoots produced. Like most species of "Sphagnum", this moss has mild antiseptic capabilities. It is very absorbent and acidic, and therefore creates environments not suitable for bacterial growth. These mosses were used up until World War I to pack wounds on the
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.
