Numberwatch

Drawing your attention to the excellent blog "Numberwatch", dediceted to the misuse of statistics and science to scare the public.
See side bar for link.
The "Number of the Month" collects the latest insanities, errors and downright lies that infest the popular press.
This month he picks apart a fancy scheme to fly wind turbines in the upper atmosphere and produce electricity that way. (Briefly, the real problem is not flying it - it's getting the electricity down the cable).
Might also be a problem with conservation of energy too - if the wind is providing enough energy to lift it, can it also be providing a surplus too?

Worth a regular look.
