Ceramic fuel cells thus offer a more efficient and less polluting alternative to currentpowergeneration technologies.By-products from fuel cells are high quality heat, carbon dioxide and steam.
燃料电池生成的副产品都是高热质的热量、二氧化碳和蒸汽。

That means the next generation of power lines could carry up to a quarter more current without adding any more bulky insulation.
由此可见，下一代电线会比现在多传输四分之一的电流，而且不需要添加任何大容量的绝缘材料。

They are able to align themselves in the current like windsocks at an aerodrome, so that they find the best position for powergeneration.
