Science / Re: Direct Down Wind Faster Than The Wind

In 2020 one lone voice of reason will be still mocking everyone else for falling for this huge scam.

As I said earlier, as long as YOU believe in this, FX, the more sure I am that it is nonsense.

Here is a perfect description of the problem faced by the Wai Wai people ... and all such people groups living in the Amazon rain forest who have traditionally depended on slash and burn cassava cultivation plus hunting / fishing / gathering.

Quote
Following contact, the Matsés reorganized into larger, fixed super-nucleated villages along the rivers at the encouragement of missionaries to facilitate assimilation into modern culture and access to trade goods. This new permanence of settlement, coupled with the old practice of slash-and-burn agriculture, has led to rings of increasing disturbed forest around each community. Once the soil gets exhausted in a few short years after a burn, the Matsés have no alternative but to cut virgin rainforest to create new farms each year, edging their fields farther and farther away from their fixed settlements. This creates a significant burden for the families carrying heavy loads of bananas and sacks of cassava (Manihot esculenta) for as long as two-hours to return back home. It also makes for longer walks for the men on hunting trips.

Why did the missionaries encourage higher density settlements?  Aren't they aware of the Tower of Babel account in the Bible?

That being said, I do applaud the missionaries for achieving peace between this group and the Peruvian government.

Recent history
The Matsés made their first permanent contact with the outside world in 1969 when they accepted SIL missionaries into their communities. Before that date, they were in effect at warfare with the Peruvian government which had bombed their villages with napalm and sent the Peruvian army to invade their communities. Dan James Pantone and Bjorn Svensson wrote an article about how the Matsés made peaceful contact with the outside world in the Native Planet Journal called "Matsés First Contact: The End of Isolation" [1]. At present, relations between the Matsés people and the Peruvian government are very peaceful. https://en.wikipedia.org/wiki/Mats%C3%A9s

I also applaud this permaculture group trying to change things but I myself would use a small animal husbandry model.

No I didn't claim that the reality-based community was running from my 100 proofs. I claimed that the fake science crowd was running from my 100 proofs.

And my claim still stands.

You are one confused mo fo.
And here the thread stands, a testament to Dave's alternative-reality enthusiasm and patent dishonesty.
Dave doesn't have the courage to learn, but he has the smarts to figure out his PRATTs don't work, so that's "progress".

And the relationship between Arctic warmth and severe winter weather was strongest in in the northeastern U.S. -- in fact, a temperature spike in the Arctic meant that the U.S. Northeast was two to four times more likely than usual to experience a bout of extreme winter weather, the scientists reported in a new study.

I noticed the inverse relation, but hesitated to mention it until someone who studies these things did.
From when I started this topic
Now you can blame record cold and snow on global warming.  Or rather on people, who obviously control the weather now.

That's right, we are making the winters colder.

It's science.
Maybe you should read a topic before posting in it.

"A couple of years back, Rick Cavallaro and his wind-powered car--Blackbird--silenced an online debate about whether its possible for a wind-powered vehicle to move downwind faster than the speed of the wind itself by going out and outrunning the wind."

The balloon test was a bust. There is no point in arguing about that any more.

The physics of the treadmill is far more interesting. I will continue to discuss that later.

Cassava is a highly productive crop in terms of food calories produced per unit land area per unit of time, significantly higher than other staple crops. Cassava can produce food calories at rates exceeding 250,000 cal/hectare/day compared with 176,000 for rice, 110,000 for wheat, and 200,000 for maize (corn).

Trying to find a more specific source than this, especially since I'm not sure whether they mean calories or Calories (i.e. kilocalories).

Well, it does say "food calories".

Food calories are Calories or kilocalories.

It "seems" false? I am sure if you really thought that, you would show me why!


In this case it is your normal sloppy expression and definition. You say "you could have been at right angles to the wind, for all we know and of course your streamer will be pointing backwards at 20 mph!"

But as you haven't specified the wind speed, you can't get away with saying the streamer would be pointing "backwards", even if you didn't mean 'directly' backwards. It would be at an angle, which we can't see from the footage anyway, but the point is your statement therefore "seems false".

This is better than most of your statements which are "obviously false", so congratulations , partial credit.

The wind was not strong, it was no more than 10 mph, and the BB was making 20 mph as shown on my speedometer.  They had a gps on the BB and it recorded a peak of 22 mph.
The video shot through my car window shows the streamer attached to the pvc pole on my car blowing backward while we stayed alongside the BB.


Without the balloons to indicate the wind direction, you could have been at right angles to the wind, for all we know and of course your streamer will be pointing backwards at 20 mph!


Do go on.  :parrot:

OK, if you insist
We don't know what the windspeed was, but If the wind was blowing at 10 mph and the cart was travelling at 20 mph at an angle to the wind, (which is possible) the streamers will point backwards.
Does this in any way demonstrate ddwfttw to you?
Iceboats do this all the time and they do not achieve ddwfttw or claim to.
In order for the streamer pointing backwards to be meaningful, we need to know the cart was travelling ddw, or very close to it.
Since the balloons travelled off at an angle when they were released, it is clear the cart and the MikeB's car, were not going ddw and the streamers indication is meaningless.
But I do understand that crackpots must cling to the last straw even though the balloon test was an abject failure.
As I said, I give MikeB credit for trying but all that fumbling around just doesn't make any sense. They could have driven up ahead of the cart and just parked and one of them releases the balloons as the cart approaches, while the other films the whole scene. The fact is, these carts do not go ddwfttw and that is the reason why there is no film evidence of it, and there never will be any film evidence of it.


Except for all the film evidence that is.

There is none. That was the whole point of the balloon exercise. It failed.



And, if
the cart was travelling at 20 mph at an angle to the wind, (which is possible)

What is the critical angle which you believe there must be in order for it to be possible?

For example at 60 degrees to the wind anything with a sail can go 2X windspeed.

FFS can't you even do simple trig?


This is really interesting Heinz. Yes, I can do simple trig, actually did some just before to see if your assertion that ;

Seems false.

But anyway, please educate me (us) on your theory
For example at 60 degrees to the wind anything with a sail can go 2X windspeed.

And, BTW, the most recent video and Blackbird operations may not have all the experimental and instrumentation artifacts needed for proof, but the operations from a few years ago, ratified by the yacht club etc do provide very compelling evidence.

It "seems" false? I am sure if you really thought that, you would show me why!

Of course it is not false and if you cannot work it out there is no sense in me educating you about it.

And, who gives a rat's ass about what some yacht club "certified"?

If we are talking Physics here, you need to provide some scientific evidence, and you have not. In fact, the fiasco with the balloons strongly suggests this is all a load of horseshit.

BTW, the streamer in MikeB's video sometimes just hangs straight down, with the car going 20 mph, so the wind was gusting at least to 20 mph, even at an angle to the direct downwind direction!

That is strong evidence against the claim of a 10 mph wind!

The claim is a farce, face it.
