这个是对结论的评估!!不是对 extracting uranium from seawater的评估
C只是说是否有这种技术使cost下降
看看是否评估until the cost of extracting uranium from seawater can
somehow be reduced, this method of obtaining uranium is unlikely to be
commercially viable
正面: 存在这种技术: 文章本来就在说是cost太高,现在可以降低cost。。。那么商业化就变的viable ...支持了结论
反面:不存在这种技术 ....咋评估????没有任何东西可以拿来评估until the cost of extracting uranium from seawater can
somehow be reduced, this method of obtaining uranium is unlikely to be
commercially viable
