Will a perpetual motion machine ever be invented or are those that try just deluded and wasting their time.The patent offices do not accept such things.

speed holes alanThe stall demonstrated is the leaking of air from beneath the wing to the top of the wing which creates destructive turbulence, due to the angle and trim that is required upside down and the lack of thrust capability that is required to summount this turbulence that most planes exhibit, this is why the planes have a bit of trouble flying upside down.Air leaking through solid aluminum. Never thought of that before.
Perhaps it's the high pressure air creeping round to fill the low pressure area above the wing,sounds like capitulation
but you have stated that there is no pressure reduction above the wing. And the air above the wing is still moving backwards at 50 - 70 kt in the video.No I didn't, if a falling object creates a bow wave of pressure, it has to create negative pressure to the stern, or rear., the area it has just passed through., something to do with vacuum creation.
An airplane is held up by the wing having an angle onto the oncoming air, thus planing it. If wings needed to be aerofoil, flat shape wings would now work but yet they do.Yes but that is up for debate whether a plane utilises the low pressure high pressure principle of boomerangs or the magnus effect, or whether a aeroplane simply planes the air, creating the pressure beneath the wing. Me personally believe the 2nd.As you increase the angle of attack, the pressure below the wing obviously increases until α = 90°. But as shown in the video clip, when α > 15° or thereabouts, the flow over the upper surface becomes turbulent and, er, the lift decreases sharply, producing a stall condition.
Only an idiot, an aerodynamicist or a qualified flying instructor would conclude that this implies that the airflow over the upper surface contributes significantly to lift. A born genius like yourself knows that airplanes are held up by faith, magic, and the underside of the wing.
Thousands of fools all over the world are busy right now removing dew, frost or insects from the upper surfaces, and designing ever more "efficient" curves that clearly contribute nothing to controlled flight. O we of little faith!
Drivel.Yes but that is up for debate whether a plane utilises the low pressure high pressure principle of boomerangs or the magnus effect, or whether a aeroplane simply planes the air, creating the pressure beneath the wing. Me personally believe the 2nd.
There are plenty of elementary texts on aerofoils, well worth studying before trying to explain it to others. I think it was part of the National Curriculum for 10-year-olds a few years ago.
Bored Chemist knows a lot more about aerodynamics than NASA, who keep designing asymmetric aerofoils in the mistaken belief that the upper surface has some influence on lift. You would think that they would have learned their lesson after 105 years and billions of dollars getting it wrong.
If you visit a science museum, beware! They will try to kid you that aeroplanes can fly and the world is not flat.
The wings on a stunt plane are designed to fly in Australia and the set to the fuselage are equal, the profile of the wing chord is the same, the angle on the fuselage is 90 degrees. This allows the economic and easy stunt antics. They are not the economy that Easy jet look for though.

The Chicxulub impactor had an estimated diameter of 11–81 kilometers (6.8–50.3 mi), and delivered an estimated energy of 21–921 billion Hiroshima A-bombs (between 1.3×1024 and 5.8×1025 joules, or 1.3–58 yottajoules).
You will have to try harder for partial agreement, I agree it is possible that a part of Earth's gold may be ejected from the sun, with some reasonable device owing to golds properties differing from iron or hydrogen. But possibilities is along way from a theory. It is possible that the atoms in another parallel universe are ejected into this universe by leprechauns trying to hide their gold.I suppose this theory has some credit. A lump of gold the same volume and velocity has more energy than a lump of aluminium. The same weight in gold is denser than a lump of aluminium. So centrifugal seperation is a possibility. The electrical magnetic qualities are worth investigating too, at the varying temperatures you envisage this theory happening at.I think there is a lot going on in stars that is yet to be discovered. The core of some planets including ours is a powerhouse factory but nothing compared to the heart of a star. Thanks for your partial agreement.
So what is the diagnosis of what appears to be a palpable lump?plus loss of consciousness, waking up on the floor covered in my own urine; double vision; weak heartbeat; shortness of breath; light-headed; dizzy loss of balance; severe pain

My neighbors are dying at an astronomical rate, and there is an elementary school near; but that alliance above is the most powerful mafia in the world insisting violently that this is not infectious or transmissible. There's not even a lump, because it's just psychiatric. If you disagree, big problems from the group above.
Well Alan where is this carbon dioxide disappearing too? If its into trees unfortunately the bacteria has evolved so this carbon is not being transmuted back into coal and oil, but is released again when the tree bio degrades.I believe it is to do with the sudden drop in fossil fuel usage leading to global cooling.That would be really annoying. Part of the carbon dioxide catechism is that it hangs around in the atmosphere for ages with a half life of between 5 and 30 years depending on where you worship.

So centrifugal seperation is a possibility. The electrical magnetic qualities are worth investigating too, at the varying temperatures you envisage this theory happening at.But where did the gold in the sun come from? Did it sink to the centre of the primeval sun? If so how is there lead copper or iron on earth?I must say I am no alchemist or geologist But I think most metals originated during the formation of the planets. Some say that gold and other rare heavy metals originated in supernova explosions and was flung throughout the universe that way. I think that stars/sun is more than capable of producing gold by their own fusion taking place deep within. The gold would be delivered to earth as very fine particle size and buildup over the time the earth has existed most of the gold has been heated on earth and with geological events sunk deep in the earth most of the gold we find has moved back to the surface plated to quartz rock. This plating breaks up and is the gold dust and flakes in the rivers. Nuggets are pieces of gold vain gold veins are accumulated gold dust that has been heated at depths.
