In March last year I posted about the installation of this tidal power generator [ 1 ]. Sadly earlier this month the company running it announced that it had gone into liquidation [ 2 ]. It seems the use of a vertical turbine was technically flawed and unsuitable for commercial use. It's one of those instances were the small scale models gave misleadingly optimistic results that the full scale could not deliver. This is a considerable setback to the development of tidal power on the Humber.
