Windmills do work, lots of work, and they're just powered by air.

But THEY are designed to face into the airflow.
Just like your ram air generator.
Not be sideways to the airflow like a wheel spinner.
(which does not depend on airflow to spin it)
When you hook it up to your compressor load, it

It would take only a tiny amount of power to pump a few cubic inches
of air a day. At thousands of strokes per day, its displacement would
be tiny... think about a piston the size of a pencil lead.


Nobody would buy either one. But that doesn't make the ideas much less
interesting. You can never develop new stuff if you whack-a-mole every
idea as soon as it pops up.

John

From what you've posted,that guy patented your concept 10 years ago,and
AFAIK,no one has seen any prototype proving it would work.

Which doesn't say much for the present competence of the USPTO.

"Reduction to practice" is supposed to be one of the criteria for
award.

Consider a spoked spinner on a car going a steady 60 miles
per hour. Assume a centrifugal clutch so that it spins at
the same rate as the wheel.

The tips of the spokes on the top will be moving at over
100 miles per hour relative to the air. The tips of the
spokes on the bottom will be moving at less than 20 mph.

You don't think that 100 mph wind will put enough torque
on the spinner that it could be tapped to drive a piston
the size of a pencil lead?

No, in fact, I've never heard of it. But you're talking cable,
not real TV, right? ;-)

Well, they certainly could - just shape the blades like this:

Kinda like little scoops.

Macon?? That's almost as good as having "...bored..." do it ;-)

No, MissingProng can't do math at all. He's entirely number-phobic.



You're an idiot. I can do the math without even making a single actual
calculation.

That's very Zen: doing the math without doing the math.
It is 100% obvious that it is a futile endeavor, and then
there are several other factors that make it a prohibitive venture.

The term for today is:

UNSPRUNG WEIGHT

You know... that thing that one does NOT want to add to their
suspension assembly, particularly at the wheel... ;-]

Gosh, why do people have wheel covers?

John

Generally found on NON-performance autos.

Is wheel bling found on performance autos?
(ones people don't care about handling or unsprung weight)

How many care? ISTM that properly inflated tires is more important
for "performance" than bling.
Also,often found on the side of the road after passing a pothole. ;-)

As opposed to Dimbulb in this argument (found in the middle of the
road with John's tire marks up his backside).

In Orlando,there are few service stations that have repair bays/mechanics.

The civilized areas of the country aren't as Mickey-Mouse as Orlando.
google the MF-1040,I bought it at PepBoys.
It runs on 12 volts DC from your cig lighter outlet.
As I said,it's not one of those cheapo auto compressors.

$21 puts it in the cheapo class. I have no use for one. My house is
plumbed for air. My next one will have compressed air in every room.
....but she doesn't know it yet. ;-)

Is wheel bling found on performance autos?

Most of them have aftermarket rims that do not need/won't accept wheel
covers. Some of those rims come with built-in spinners.
Spinners are considered excess weight,and tacky.

Even higher-level factory autos now come with non-wheel-cover rims.
Most people who use the term "bling" would not consider them to BE
"bling",not being gaudy enough. "Bling" is about ATTENTION.
How many care? ISTM that properly inflated tires is more important
for "performance" than bling.

There are cars built for "looks",and cars built for "go",looks being
secondary. "Bling" is about ATTENTION.

The civilized areas of the country aren't as Mickey-Mouse as Orlando.

Ah,the standard liberal comeback;"civilized".How elitist.
(so much for their vaunted "diversity";if you're not like us,you're
"uncivilized".)

Did you hear about the Democrats calling for(and getting) immunizations
before attending a NASCAR race? I guess that sort is too icky for the
Democrats to be near without having their shots.
$21 puts it in the cheapo class.


No,inexpensive,but not "cheap".
It has a powerful motor,not some slot-car salvage,metal gears,all-metal
housing,and is quiet compared to those "cheapo" auto compressors.
$21 was the SALE price,including a rebate.It's similar to what AAA
responders have in their service vehicles.(but not chrome plated like
theirs)

Of course,you didn't bother to check it out before tagging it as "cheapo".
I have no use for one. My house is
plumbed for air.

Which doesn't do you any good away from home...
(and I can't run a compressor in my apartment,it disturbs the neighbors)

No,he's right;those wheel spinners use low friction bearings,and any
crud will stop them.

So, you won't do the math either.

John





Math without practical experience is useless.

Practical experience without math is amateur guesswork.

John

John, I think you've got yourself out on a limb, on the wrong side of
the saw ;-)

I think it's you who has to put some numbers to it.

...Jim Thompson

I already did. And Guy confirmed it.

John

Macon?? That's almost as good as having "...bored..." do it ;-)


No, MissingProng can't do math at all. He's entirely number-phobic.

I think you need a pendulum of _substantial weight_ so that it
_doesn't rotate, but acts as a "pinning" point for the piston(s).


That could work, too. But we'd need a small amount of energy per day.
I'm guessing 1 kilojoule would be plenty - and easy to get - based on
the performance of a little cigaret-lighter-plugin compressor I have.
The bling-spinner idea was cute, and would be a nice sales gimmick.


What
weight does it take for a 1/2" piston working against 30PSI, and what
are the respective arm lengths?


Why 1/2"? The amount of air we'd need is tiny.

I'm not going to design it, much less build one to prove something to
rude strangers, but the numbers seem well in the ballpark of
feasibility. That's the first step in engineering, a quick numerical
estimate to see if an idea has a chance of working. This one does.

John

Low tire pressure alarms will become standard and manditory in a year or
two.
They already are stock on high end vehicles.


They are ridiculously more cost effective than zillions of pumps that
does nothing for virtually all of their lifetimes.

Of course, that was in Britain.

My Q45 has them. But rather annoying this time of year where daytime
temperature is 90°F and nighttime is 60°F. The inflation placard
advises 33PSI, the alarm goes off at 30PSI :-(

By the time I'm awake it's usually 70°+. Guess I need to sit down and
calculate what I should inflate to for 33PSI at 50°F (allowing for
WINTER temperatures ;-)

Perhaps you have seen the TV show "TMZ" or the web site TMZ.COM?
The show is on every night at 11:30 PM for those of us lving in
Southern California and interested in that sort of thing.

From TMZ.com:
What does TMZ stand for?
'TMZ' stands for "Thirty Mile Zone," a term which originated
in the 1960's. Due to the growth of 'on location' shoots,
studios established a "thirty mile zone" to monitor the
regulations of shooting throughout Hollywood. The zone was
originally centered in Los Angeles around the old offices
of The Association of Motion Pictures and Television Producers
at Beverly and La Cienega Boulevards in California. It was
often said that "Everything entertainment happens in the
'Thirty Mile Zone.'" So essentially, the "Thirty Mile Zone"
represents the epicenter of Hollywood! Interesting, huh?!

Hollywood is, as usual, self-absorbed, self-referential, and pretty
much devoid of imagination, taste, or integrity.

So there.

Car tires usually run about 32 psi.


Bullshit. Your old POS high profile radials MAYBE, but the modern, low
profile tires kids use these days does not follow that claim.

And we design electronics, and you don't.

Sure I do, dipshit. When did I ever say that I didn't?
You can't, not because
you're too dumb, but because you refuse to do simple math,

You're an idiot, and you have yet again made another retarded
assumption.
and because
you refuse to consider new ideas.

Yet another retarded assumption. I considered it for as long as it
needed to be considered. A whole five seconds.

Want some math? That's 5000 milliseconds.
And you won't fix either problem

Problems you made up... err... pulled out of your ass?
because you're too damned stubborn.

Same remark. You're a goddamned idiot.
Pbbbbbttttt!


And an illiterate as well (unless that is a fag noise).
