Hello again and thanks for revisiting the Free Energy Nation blog
I found a really good video which shows how wonderful it is to take nature as your teacher and design products based on the evolved and natural R&D which nature has been perfecting for at least 3.8 billion years.
>p>This time a successfull engineer also intuits about spirals and builds a water impeller which greatly influences energy savings in coolers: Just like Schauberger this engineer contemplated nature and reached to this design decision. Let me throw one picture related to Schauberger's work too ;)...amazing thought patterns!
