>> Correct me if I'm wrong, but doubling the speed of wind should therefore MORE than quadruples its force. More molecules per second and vastly more energy per molecule.
DE - although I (still) agree with you from a logic point of view - the equations for pressure as a function of velocity say we would be wrong on that one.
It is one of the vagaries that have prevented me from every understanding this apparent discrepancy. Took an engineering course in 'alternate energy' at Texas A&M - and (closely associated to this topic) it was stated time and again that two bladed wind turbines were just as efficient as four bladed. Never understand that, but my brother, who has a lot of aeronautical engineering under his wing, confirmed that was indeed the case, two bladed props on aircraft are just as efficient as four bladed ones. So ...in light of those basis- WTH are there three and four (and more) bladed props on aircraft ??
I like the visual of the ball bearing experiment - haven't ever seen it - but can picture it quite clearly. Thanks. *S*
And yes, Einstein's equation caught my fancy during replying as soon as I wrote the equation out, where c is the speed of light. Now here's a conundrum - we are told that as any mass approaches the speed of light, it's mass actually goes to infinity ...so ... why is the E limited ? *w* and chuckling - guess I'm no Einstein,eh ?
