Although its lifetime in the atmosphere as a free gas is much shorter than CO2, it is 23 times more potent in terms of its heat trapping ability.
虽然它作为自由气体在大气中的寿命比二氧化碳要短的多，但要说吸热能力，它比后者强23倍。
An altogether different, and better, idea is to use the sea to generate green, CO2-free energy.
一个完全不同的更好的思路是，利用海洋产生绿色、无co2的能量。
This means the car produces no CO2 emissions directly, but whether it is emission-free overall depends on the source of the energy used to produce the hydrogen.
这意味着汽车不直接产生二氧化碳排放，但是否完全零排放取决于用来制造氢的能量原料。
After all, the world could use more CO2-free forms of energy generation and this one's just a few kilometers beneath our feet.
总的来说，全世界或许应该多使用不产生二氧化碳的能源，而地热能就蕴藏在我们脚下数千米的地方而已。
