So much the more than In the past years the rock beat frequency has been steadily risen from 2 per second (normal hart beat double pattern) to 3 per seconds (corresponding to a puls frequency of 90, as it happens when we are angry of anxious). Beverage manufacturers like Red Bull have tuned-in to this adrenaline generating trend in order to allow youngsters to sustain the faster heart beat resulting from long-lasting exposure in disco-dancing places. Adrenaline being toxic in the longer run, death casualties among young people through arythmic heart troubles have recently been reported.

Please ban the term “wind turbine” for the time being.

While there are some experimental “real” wind turbine designs, it should be borne in mind that a “turbine” always has a casing. All the current discussion deals with WINDMILLS alone.

Horizontal axis windmills need to be placed some distance apart in order to avoid wake disturbance problems, but they have a very small footprint. Less than 2% of wind farms is used for ‘footprints’.

I suspect people are misusing the term ‘footprint’ in the case of vertical axis mills. It may well be that since they generally sit closer to the ground rather than high into the better wind they might require more square feet of land for footings than taller horizontal mills.

Thanks for popping in!

nice to see that greenman face over here
