[RE-wrenches] GTBB resistance

[Dan Fink]

Ray;

We always run a variety of made-up financial scenarios in our "Intro to
Off-Grid" classes.....we usually end up around 35 to 70 cents per kWh.

Or another way to put it....a monthly 'battery bill' of $25 to $120
depending on battery bank size, and how many years they pamper it to
last....or torture it to premature death.

The GTBB backlash from the utilities is just more smoke and
mirrors.....I'll try to get something up on HuffPost before I leave for
Canada next week.....
