Tesco Windmills

Tesco wind power

To boost their green credentials, Barrow’s central Tesco has erected a brace of wind turbines.

The really strange thing is that they go round like the clappers even when there is little or no wind. It’s instructive to compare the working turbines off Walney or up on Kirkby Moor, which are much more sedate and purposeful. If the turbine is attached to a real generator it has to work pretty hard to get the juice out.

I wonder how much energy the Tesco turbines consume? Cynical? Moi?

  1. If an AC motor is turned at a speed greater than what it is rated,it becomes a synchronous generator,producing more energy than it consumes,any energy in excess of which is demanded by the store is fed back into the grid,and needs no fancy inverters or such.Some meters actually go backwards in this condition & the company is credited for the surplus.I hope that this a possible explanation for them turning.WALLY.
