Newcastle Hydraulic Bridge: (Should That Be Spelt Hydrolic, Because It’s Water)
Michael Portillo’s Great British Train Journeys – Newcastle to Lindisfarne. BBC.
On the river Tyne a swing open bridge was operated by a simple vertical cylinder which filled with water and lifted a sixty five ton weight. They opened a valve at the bottom and the downward pressure drove the ‘Engine’. What more would you need to drive an electric generating turbine, but a row of those.
More power from one big turbine than a thousand wind turbines. I didn’t know, when I wrote about it before, that it already existed. Invented by a Newcastle Geordie.
