but we (主)still have not found (动)a solution (宾)as to how to get water from water without a lot of money.(定。修饰宾语的定语)

1. as to 是复合型介词,意思约等于 about。

2. how to get water from water without a lot of money,作as to 的宾语。不定式前有wh-word 时,相当于一个名词,故可以用在介词后。又如:

This is a small book on how to operate the machine. 这是一本关于操作机器的小册子。

They're both uncertain about what to do. 他们两人都拿不定主意该怎么办。
