Derrick doesn't really deserve to be talked down to and doubted like that and it's very gracious of him to take fault in botching the explanation but holy hell that uni prof needs to take notes from Bill Nye and just be nice.

    @@kevinlasher2812 I think the professor was overconfident, put too much weight in weak arguments (like Derek getting into Blackbird many times??), and was also condescending as you suggested. Maybe he thought he would easily win $10000. The already existing treadmill-footage clearly showed the cart wasn't being "pushed forward"; there was no "bias" in that sense (the bias was in the professor's mind that people would be as silly as to do the treadmill experiment repeatedly and always "unconsciously" push it forward). But mainly, "the video falls short of providing evidence that the motion faster than the wind occurs with a non-negative acceleration and that it is not caused by the wind variability. " Derek's treadmill experiment clearly shows there is positive acceleration relative to the ground. Unless he was suggesting that somehow the wind behind the propeller acquires higer speeds, or to vary so much so as to get the negative acceleration he mentioned. Again, clearly not present in the treadmill experiments. It seems he is trying to look gracious "Oh well, I had to concede if I wasn't 100% correct". But he was just wrong. To me, the main issue was understanding how the "turbine" worked. In any case, he should have gotten himself fully familiarized with the problem (or maybe he actually was, and is playing dumb) before betting that amount of money...Apparently didn't even check the literature on the problem. The professor suggested the bet right? Kind of weird. Not sure what he wanted to get out of it. Maybe "school a youtuber"? Prevent the spread of what he thought was pseudoscience? In brief, arrogance got the better of him.

    The main difference between politics and science is science deals with matters of truth, while politics deal with matters of morality. The ultimate goal of politics is to create a society that maximizes justice and comfort for the individuals in that society as well as determine who or what that society is. In a melting pot like the US with such diverse opinions and ideologies pepole will naturally butt heads. If you reached the end of this then thank you for reading and please share your thoughts I like discussing this stuff on the internet, it's fun :)

    @I love you but You can talk about the past though, and it's still hard to show direct causality. Look how many people still argue that communism and socialism would be good for people even though every attempt at it has ended very badly. The only people who seem to be able to convincingly draw conclusions of casuality from policies are largely ignored- Thomas Sowell for example. And even then it isn't FACT, it's just conjecture and anicdote.

    The problem was his initial response to the experiments. There were multiple examples, all with the same result. And he just refused to not only believe it, but to even bother to test it himself first. And I believe the only reason he was humble was because it was all public. He was so sure he was right, but got essentially destroyed.

Would love to see videos with a similar styled format! The appeal for me however is seeing two smart people discuss small possible problems, not crazy stuff. Had to rewatch a few times to follow the math a bit better, and thats what Im here for.

    Derek's misleading when he says Professor Kusenko “changed his mind in light of the evidence.” Professor Kusenko never changed his mind and still believes the Blackbird doesn’t work. He only conceded the bet on a technicality, still insisting it was just the wind pushing it along. From Rick Cavallero: "He conceded on a technicality - that the vehicle moves marginally faster than the wind temporarily." "I offered him another $10,000 bet because his technicality is entirely wrong, but I know I won't be hearing from him." So Professor Kusenko is not a rockstar or some scientific legend. Personally, I think he was just an egotistical professor who thought he could publicly school Rick Cavellero and some dumb KZreadr, only to end up getting schooled himself. And his ego was too bruised for him to ever even consider admitting he was be wrong. Hardly very scientific of him now...

I love it because that's an old brain teaser that we got as engineering students and even machinist's training. Very easy, the output speed is equal to the ratio of the input gear and the output gear, . regardless of the size of intermediate gears. There are no co-axial gear sets, only independent idlers, therefore one tooth is one tooth consistently through the train. The answer is 30/60, or 1:2. Output is 5 RPS.

    especially since some of his concerns/challenges are actually valid concerns that should be tested for, with a "fail condition" (i.e. how the hypothesis can be disproven) the wind gradient for example, is a really good challange, because there is a diffrence in wind speed as you go higher, and a tall land based wind powered vehicle could make use of that to travel faster than the ground wind, even if the operator doesn't realise it. to disprove the hypothesis that the wind gradient is causing the vehicle to appear to go faster than the wind, you just need to show that the vehicle is going faster than the wind at the highest point on the vehicle. (or test in an enviroment where the wind gradient is minimal, like in a hanger with a fan model and a treadmill, probably with a treadmill set with a variable speed control to simulate the vehicle moving across the ground. that way twind speed, and the vehicle speed.) the gust hypothesis (a high gust of wind pushes you faster than the "normal" speed, which may look like you are traveling faster than the wind. The treadmill set up would also be a great way to disprove this hypothosis.

    @@Reverend_SalemThe treadmill test is flawed though. By holding the car on the treadmill, the force the person imparted was greater in the beginning as it not only kept the car at a constant speed but also used the resistance of the wheels to build up the speed of the fan to the point where the gust from the propeller exceeded the resistance of motor powering the propeller at the treadmill’s speed. As the fan got faster and faster, she had to use less force to keep the car still, and eventually had to use slightly more force in the opposite direction to keep it still . She was essentially charging the propeller like a battery. This would be like if there was a 30mph wind gust, but the resistance of the gears is increased such that cart can only reach 15mph and the rest of that energy is used to power the propeller. Then the wind gust drops to 15. You reduce the resistance of the gears so that all of the wind gust goes to pushing the cart forward, but the propellers still have inertia so they push forward with the energy built up under the 30mph wind gust. The cart will lurch forward faster than the 15mph wind gust, just as it did on the treadmill.

    The answer is in an analysis of the function of the propeller acting as an airfoil. The propeller blades are rotating and therefore at an angle to the apparent wind. As such they can generate forces to propel them at speeds that exceed the speed of the wind. This is how ice boats can achieve speeds five times the speed of the wind.

    very interesting experiment, thanks! From what I saw in the first video, I realized that each pinwheel represents the sail of a ship. And as has been shown, a sailing ship moves at an angle faster than straight ahead of the wind, and if it goes to the right for a while, then to the left, the ship will go faster than the wind. The spinner on the car is a sail that pulls to the left on half a turn and to the right on the other half turn, from here and at full turn it reaches beyond the wind, so it travels faster than the wind. It's like riding a bicycle, we push the pedal right and left, and as a result we accelerate forward, only here the angular force of the sail is used, when right, when left, for each complete rotation, and the car goes faster than the force that pushes the pedals.

    I'm still working my head around the forces involved there. So you apply a forward motion to the object, and that makes the wheel spin backwards propel it forwards at a higher speed than the force being applied. Saying it out loud does make it work a little better in my mind, it's just the top wheel rotating backwards that feels strange, since how is it applying the forward motion when the wheel is moving backwards. Friction working oddly?

But it really got me when you made the rolling-example with the woodplank. that really does now make sense how it can work if friction is low enough.

    Good point. I don't know if I've ever bet someone money about something I was 100% confident I was right. I'm sure they're well compensated in their professions, but $10K is still very different than betting $10. I don't think too many people, regardless of financial standing, would agree to such a large bet if they believed there was a fair chance they'd lose. Maybe the professor understood that (including as Derek said...a public bet to boot) and was fine with it, but I'd bet (let's stick with $10K ;) ) he was confident he'd win. So right...says a lot about one's character by paying up a solid chunk o' cash like that. Good character these days, is especially valuable. I believe we're more influenced than we might expect by others higher or lower nature even if only indirect or casual contact.

    ​@@FrenchcoreFlava The equation for the propeller force is just an approximation based on the velocity of the wind and the vehicle. So the fact that it gives you an infinity when the two velocities are the same is because the equation is not "exact" but only a (first-order) approximation and not because the scientific basis of deriving it is wrong.

    For me, it resembles the action of a sail boat that travels faster than the wind fillings its sails by cutting across the wind as long as it has sufficient fins or sharp bow to tract through the water. Thus, the sail acts as an air foil like your propeller and the bow/fin keel alike to your wheels. Where they are mechanically linked by the Mast as your chain does. Anyway, that what I immediately thought when I saw the testing. Very entertaining and thought-provoking. Loved it.

    You are correct. Just like the keel on the sailboat, the airfoil gearing constraint to the wheels ensures that for every unit of downwind travel, the airfoil is forced to make some specified unit ratio of crosswind travel. Remove the keel effect from a sailboat and it merely drifts downwind at some speed less than the wind. Cut the chain to the wheels and the Blackbird does the same.

    Translation for an industrial engineer. An electric motor with a gearbox can increase the speed of the output with the same energy input. Energy requirement stays (relatively, minus friction) the same despite increased speed, and given there is enough torque to move said object on output shaft the output will move faster.
