Okey dokey, Sparky, answer this:
How do you reconcile the vectors to eliminate the components that
_don't_ go in the direction you're intending to travel? Ever notice a
sailboat has to tack back and forth? Ever hear of leeway?
Think of it like this:
The rotor blades tack up wind.
They are not moving straight into the wind but sidewards relative to
the vehicle. They may spin much faster sidewards then the bike is
moving forwards.
Quoted message said:Let me guess, you're going to be pulling so much energy out of the
wind that you'll be able to make the bike a lot heavier so it won't
get blown off of the road. That's what I've always wanted - a two ton
vehicle that I don't have to pedal. Oh, wait, I already have one!
hehehe

my math cant possibly be good enough for you.
There are enough website where you can read how much energy a windmill
generates.
Quoted message said:including reasonable numbers,
Doubling the speed of a vehicle costs 4 times as much energy.
Doubling the wind blown onto a windmill generates 8 times as much
energy.
Assume:
moving at : 20 km/hr
wind:10 km/hr
total drag: 30 km/hr
Thats 5600% of the original wind power.
At those wind speeds a small mill can do usefull work.
Of course you would have to go really fast to make this self run with
a small propellor/rotor/windmill/sail. The point was for it to assist
cycling.
The wind force does not drop off when one accelerates into it.
Accelerating is more like cycling into a moving wall.
Quoted message said:and it works, I'll personally open up my coffers and pay for whatever
development expenses you incur.
I'm 100% convinced it works but not sure what size and for what speed
it should be engineered. Not at all sure about creating a useful
vortex with a prop.
you can help figure out how to build it.
Going down the wind it doesn't work but there a rotor would be a good
means of propulsion. One can convert energy from the wheels onto the
rotor and use that to push against the wind.
This topic is about using the vacuum and the pressure from the
centrifugal forces.
I want to do more with the whirly air.
If you ask around you can conclude people don't know about sailing up
the wind and Ærodynamics treats both drag and vortexi as problems.
There is loads of documentation on making wind and vortexi go away.
Same goes for resonance, and Æroflutter.
It's far far from an inspired mindset. It's like playing a victim
role. It's problem~thinking, looking for problems means you will find
them. It's just like looking for solutions. I prefer to look for the
fun of looking and develop the skill of looking. :-o)
Things are not what they seem! I can tell you that much already! If I
wouldn't be so busy looking at things I would see enough problems to
spend lifetimes complaining about. lol
lets give an example. I was looking into this.
I see a tire drags air along it's rim, this airstream becomes thicker
and more violent when you go faster.

I'm not complaining about how Aerodynamics works I'm merely observing
how a mindset doesn't try to create that what it refers to as
"problems".
Lots of people think propelling up the wind is impossible.
But it's forces not work, so it's just a mater of gearing.
It makes me think there is lots to be discovered here.
