Carrington Moss of years this raises the level of peat and forms a gently sloping dome (hence, raised). Such areas support a wide range of flora and fauna; "Sphagnum balticum", a medium-sized bog moss, was recorded on Carrington Moss in the 1880s, although locally it is now presumed to be extinct. Lancashire- or bog asphodel ("Narthecium ossifragum"), white beak-sedge ("Rhynchospora alba"), cranberries, bog-rosemary ("Andromeda polifolia"), and the cotton sedge have also been recorded. In 1923 species of trees recorded by E. Price Evans for the "Journal of Ecology" included English oak ("Quercus robur"), and common ash ("Fraxinus excelsior"). Undergrowth included common hazel
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.
