| 摘要： | The case against using hydrogen as a substitute for diesel in internal combustion engines is a strong one, on paper at least. It retains all the inefficiencies and complexities of a reciprocating engine, with pumping losses, internal friction, and heat ejection robbing more than half of the input energy, while using a difficult-to-handle gas as a fuel. Hydrogen fuel cells are far quieter and more efficient, but electric vehicle guru Elon Musk is disparaging about even them, dubbing them 'fool cells' because much less electrical energy is lost charging a battery than in the business of converting water to hydrogen and oxygen using a lot of electricity and then combining the hydrogen with atmospheric oxygen to produce a little electricity and a small cloud of steam. |
