Re: LQD - A new definition of 'affordable' (4.00 / 2)

This is possibly a question for Crazy Horse. Is it possible to submerge turbines in the water to take advantage of the strong tidal currents as opposed to damming the Severn estuary? Also, could something similar (submerged turbines without damming) be done in the Thames estuary, which also has large tidal currents?

In water, one could also use a vertical axis turbine to avoid having to reorient the nacelle in turbulent water. My reasoning is that the higher density of water may put more strain on the mount point of the nacelle on the base of the turbine.

They are doing it in the East River in NYC.

The problem (none / 0)

is that maintenance under water is a bitch. It's not bankable as of today.

Re: The problem (none / 1)

maintenance under water is a bitch.

As is off-shore oil platform maintenance. Companies supplying divers for the oil industry could supply divers for these facilities. Hopefully, the East River Project will provide information on that issue. It may prove possible to remove-repair-reinstall. For some aspects tidal estuaries seem worst case, but at least, in this case, they are close to shore.
