It is extremely doubtful whether at the beginning a really economic engine could be made, that is, one cheap enough to make it worth putting in a car.  But it seems safe to say that eventually, as techniques and mass production come in atomic engines, the price will go down.  This is basic economics, and manufacturers should eventually be able to produce something that will at least be cheaper than having to pay for petrol during the lifetime of the car.现在人们极其怀疑，能否造出来一台真正经济适用，即价格足以低廉可以安装到汽车上的原子能引擎。 但是，现在似乎可以说，随着技术的进步，以及原子能引擎产量的扩大，价格最终会降下来。这是最基本的经济考量。 有关厂家最终应该能生产出比较理想的原子能引擎，这种引擎的价格至少要低于普通汽车在其使用年限内必须支付的全部汽油费的总和。
