A supporter of Energy from nowhere and you are turning to Newton!!!!!!
Nobody but you is making the claim that the cart gets Energy from nowhere, but being as you haven't any idea, can't learn, and won't learn, how it works, that doesn't bother anybody.
In any case I was right that the thrust of a prop...
"I was right" - boy you don't get to say that very often, eh? Of course, even when you do it's false; in fact you were not
right because in the previous post you said power, not thrust
, was proportional to V^2 (and you said it again; see below). So get a clue, Stooge. That formula is for Thrust, not power. And as Thrust is Force it has exactly the squared relationship wrt velocity that I stated without any need to look it up, like probably everyone else who understands the cart (i.e. not you). And no thank you, I don't need to look up the meanings of the other terms.
And if this is true:
The power output of a wind turbine is also a square relationship to the wind speed.
then Sir Newton is turning over in his grave, but what really gets him spinning is your even bigger gaffe in thinking that both thrust and power can have the same power law relationship to the wind speed. And gee, whaddya know, there it is at http://www.awea.org/faq/windpower.html
Wind Turbine Power:
P = 0.5 x rho x A x Cp x V^3 x Ng x Nb
Velocity bloody cubed just like I said
, you hack.
