Yes, and by "obvious" he means:
And not the nonsense you were attributing to him.
Then put them down already.
And I have 3 emails where I challenged his claim, and he hand-waved and changed the topic, ultimately giving me the usual spiel about not understanding etc.
One of the points which generated the response
you have seen was this;
"The argument is that the ratio of the “apparent wind”, to the cart’s speed, acts like a lever,so relating the forces. To overcome the obvious problems, the prop is said to travel less distance through the air, than the cart travels over the ground,
But of course, work =force*distance, and must be the same at the wheel as at the propeller.
Alternatively,
force*time, yields the relative momentum. It is a machine that claims to be driven by the headwind of its own motion. "
Now, you tell my why that momentum problem does not blow the claim out of the water, and why it was not addressed.
Smith passed on my name and e-mail address to Spork. Not my real name of course, but one created for the purpose. It was not long before TAD hinted that they know my name, but said it was in reference to something else.
But, eventually, Spork posted that name and address, as he did the "alexia" PM.
