I found his US Patent for it!Ozzie wrote: ↑Sat Oct 01, 2022 7:51 pm Actually Andrew 50 years ago we had a local inventor , I can still remember his name , Arnold Delaney. He was a bit of a local identity as he was also the Editor of the Charlestown Post. He invented a bilge pump for moored boats that worked not unlike an automatic watch . Simple rocking movement of the boat cranked a long arm with a float on the end. He patented the device and was on “The Inventors” on the ABC from memory. Not sure if it ever took off but it was as cleaver as sliced bread . Anyway maybe something will come up in a similar light to create electricity. You’re dead rightlots of energy wasted in a rocking boat.
Good grief I googled him and a link came up. This forum does lead down rabbit holes occasionally
