Work productivity - human and hydro.

Lately, the human kind of productivity has been encouraging but the hydro kind less so.  

To take the hydro kind first, - the line of the graph of cumulative kWh's generated for the current year continues to fall away from the trajectories taken in previous years:

...we have had rain, but it has been meagre and not done anything to increase energy output.  I doubt the year total will see 3000 kWh, - which would mean a 25% reduction on last year's total.

This disappointing output is not a result of any interruption in turbine operation, - it has run continuously with no interruption caused by the near miss of the tree falling next to it, - work on the clearing of which is the reason for the encouraging productivity of the human  sort:

The clearing away of the root plate of the tree is still a work in progress.  It's all being done with hand tools so it takes a while.

As I work on it, trying to remove each and every stone amongst the roots that will mean another sharpening of the chain saw's teeth, I keep telling myself "Rome wasn't built in a day", which alternates with "There are worse things to be doing in retirement"!

My thanks to my mate Paul, emptying his boot of saw dust in the picture. Without our arguments about how best to do the job, life would be less fun.
