I have been discussing with my father my latest off beat ideas and mentioned my idea re the underwater dam and he rather than tell me why it would not work told me that there is such a venture he believes near Hong Kong

. apparently they have damed a bay and use it for fresh water storage

.
So there are no new ideas it seems

.
Anyways it would seem if such a dam exists we should be considering how we could apply the technology in Australia.
AND that bay dam utilises the roof run off

.
I have not looked on the net re this but will do so and see if I can find one.
