Could the Goshawk have been a successful engine?

I just thought of another problem with steam cooling. You need absolutely pure distilled water. In a normal engine cooling system you have corrosion inhibitors but with steam it has to be pure water. Any mineral salts will turn into scale as soon as the steam condenses. You don't want the condenser loosing efficiency as it's pipework clogs with scale.

There are quite a few water additives used in steam plants as hot water and steam will react with quite a few metals.
