Thank you, professor. Also, electromagnetic coils are very inefficient, as they produce a lot of heat, especially at high speeds, instead of producing a magnetic force, and this is according to the well-known principle that the passage of electrical current through a wire produces heat.
Would it get hotter and evaporate quicker if using a black liner under the 'dirty water'? Also I'm not sure how this got recommended to me but cool demonstration nonetheless. Edit: just saw the next slide that shows the blackened surface!
solar & wind are not green tech Why? both end up with 40-60% in land fill so what is green tech? RDP Marines add on units to dam to make more power from the same volume of water used lasts 100years fully recyclable and unlike pump hydro which uses 40% more power to lift that water than is returned
one long-term problem of tidal energy extraction is that it will slow down Earth's rotation because this is where the energy is ultimately extracted from! A similar but smaller effect, that modern wind energy extraction would have, too! An amazing new scientific result about Earth's rotation is described here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SPutgPjdb8g.html Day On Earth Was 19 Hours Long For a Billion Years and The Reason is Very Surprising The wind energy extraction in Germany is already at a maximum limit, I think. And more wind turbines couldn't generate more electricity in Summa. These would just change and alter the weather (cyclones) more and more. (The same may be valid for California) In the mid-latitudes Northern Hemisphere, we used to have prevailing Westerly Winds (Coriolis effect) but now, after 2 decades of wind turbine build-up, the winds come from North or South, more often. Nobody but me seems to recognize this!
