I remember when Veritasium proved this in a video and everyone thought he was crazy for like a week before conceding.

[@ronwesilen4536]

The problem with veritasium is that he does not really understand the concepts to a level that allows him to explain them properly, so it seems wrong

[@HL1_EP1]

@@ronwesilen4536 He has a Phd in Physics education. So that's exactly what he studied for. Still, I don't like his videos that much.

[@ronwesilen4536]

@@HL1_EP1 yes but i think his older videos are a lot better because he didnt Focus so much on making them viral and more in the educating part so now It seems that he does not use enough time to really understand the concepts before putting them in the videos and a lot more filming more visual stuff or doing nicer graphics

Anyone who's into sailing knows that it is indeed possible to outrun the wind. Gybing downwind is a common method.

[@neutronenstern.]

well yes,but its different. In this case you dont go with the wind,but diagonally.

[@darrennew8211]

Given you can sail upwind, I'm not surprised you can outrun the wind downwind.

[@markjacobson4248]

Weirdly, it's a lot harder to go faster than the wind in the same direction as the wind than it is to go at an angle

[@CylindricalCow]

the purpose of the propellers is to travel "diagonally" through the air. in the car set-up, each propeller operates equivalently to the sail in a boat. that's what makes this system work. what's described in the video is an insufficient description of what's going on and doesn't properly justify how it can travel faster than the wind.

[@kotzpenner]

Finally, real troll physics

[@52flyingbicycles]

Sailing ships can also outrun the wind, particularly in directions the wind is not blowing. This doesn’t break the laws of physics, it just takes more energy out of the wind that a naive solution.

[@massgunner4152]

"what a silly troll id- the f you mean this works!"

[@NikkiTheViolist]

if you still don't understand it, this is how it works basically: 1) wind pushes vehicle kinda like a fan-shaped sailboat, making wheels move. The fan does NOT help at all. 2) wheels turn propeller backwards(!). Not in the direction you'd expect! 3) vehicle gets to same speed as wind, but wheels keep on pushing wind backwards 4) wind being pushed backwards makes vehicle speed up a little 5) Where does the energy go? Why isn't this perpetual motion? Because it's converting the momentum (from being pushed by the wind) into a fan pushing a small part of the air backwards. It can't go infinitely fast this way: all it can do is speed up until it gets balanced out by wind strength, friction, and gear efficiency like... if you want a simile imagine someone who's ice skating who gets shoved forward. And at the same time, they're also pushing back on the people shoving them. The person shoving them moves them forward, and shoving back on people gives them just a little more speed

[@back_the_bone]

Therefore, we can use the same system to go faster than li-

The problem with going faster than light is since you're on talking basis with light what's stopping you from chatting up with time?

[@r3ked272]

This isn't Troll Physics this is Honest Physics

[@tower9602]

For the same reason, heat pumps are way more efficient than burning fuel for heating

[@planets9102]

For people who think this violates thermodynamics: impulse and kinetic energy are different one is proportional to m*v=F*t (t being time) the other to (mv^2)/2 meaning that if push backward the twice the mass of something it will take exert the same force on you but take you HALF the energy ((2*mv^2)/2 < (m*(2v)^2/2 = 4*(mv^2)/2). So you can take kinetic energy from the wind and push off of the ground and because the ground has much more mass you'll gain kinetic energy even when you outpace the wind.

[@long-limbs-alias-sisifr]

so it's like we're pushing with our leg on the ground. we push backwards m, but as there is more mass on the ground than in us, it is we who move

[@bradens.3125]

physics is so fucking cool dude

[@NickWrightDataYT]

2:25 can someone PLEASE explain why East is "O" on this weather vane?? I mean it probably means "Orient" but I've NEVER seen O being used instead of E.

[@cayiika]

I assume it's German.

[@BetaDude40]

It's probably a German weather vain. the German words for North, South, East, and West are Norden, Süden, Osten, and Westen respectively, which means NSEW is NSOW

[@ManfredBlasser]

it's East in germanic languages hence the O: Osten (German, Luxembourgish) oosten (Dutch) øst (Danish, Norwegian) öst (Swedish)

[@Mythraen]

@@ManfredBlasser Thankfully, Google translate fixed your comment for me, so you said: East, East, East, east, east. Though, that does make me wonder why you said East is East. :p Also, it fixed "germanic" to "Germanic." I wonder what language it translated that from.

[@ookjannesplanting1296]

This one tripped me up, good job troll physics

[@takanara7]

1:35 It's important to point out that it's almost always the "wind driving the propeller" it's just that because the wind CAN'T push the thing backwards (because it's attached to the wheels) the wind pushes the propeller SIDEWAYS - but that means making the propeller continue to spin, basically because the propeller has an angle, the actual SURFACE of the propeller blades is never moving faster then the wind at a given point. (The only difference is when the thing is moving exactly at the speed of wind, in which case there's no force acting on the propeller really and it can 'start' like if you start one of these vehicles on a treadmill with no moving air it will start to go)

[@Enderblade18]

I always though it was because of gear ratios causing the wheels to spin x number of times for every 1 turn of the propeller

[@glitch1039]

isn't that what he's saying? i don't understand this

[@Enderblade18]

@glitch1039 He was more saying that the movement of the wheels will turn the propeller into a fan that forces air backwards, making it go faster, rather than the gear ratio explanation I thought was true.

[@fgvcosmic6752]

@Enderblade18 its a similar concept however. Like a gear, it is turning "More power but slower speed" into "less power, but greater speed

[@1KiloDepartment]

Thanks for the reply you gave me to this video! Though seems like I wasn't the only one recommending this, since someone else here posted about asking for a video about this too! :D

[@AmbroseBoaBowie]

im starting to believe perpetual motion exists but some one keeps resetting time when its discovered

[@molybdaen11]

Because wind is nut pushing you. The lack of air pressure pulls you forward.

[@TheTSense]

The real problem here is people think of two objects, the car and the wind, and both are moving at some speed. When in reality the wind is everywhere. If you move at 25 mph and the wind moves at 20 mph, you are not going to "outrun" the wind. After one hour, the wind will not be exactly 5 miles behind you and as such, can't push you. Even if you outrun the wind behind you, in front of you is more wind to work with.

[@noiseisgold3n42]

lol. that's not the problem. The problem is that wind can only provide energy at a relative velocity. Once you and the wind are moving at the same speed, you cease to have a relative velocity.

[@long-limbs-alias-sisifr]

in short, from what I understood this creates a virtuous circle when the wheels make a sort of call for energy which accelerates the fan which at one point accelerates enough to push back part of the air and accelerate at the same time, which the latter by returning increases the speed of the fan. Furthermore I imagine that this must create a pressure difference which must play a role in the acceleration. Is this it. My English is not perfect and sometimes I struggle to understand everything well

[@long-limbs-alias-sisifr]

correction: in fact what happens at the beginning is that as the ground is denser than the air pushed by the ground, and due to the mechanism of the vehicle, we will have the same effect as a leg pushing on the ground to move forward.

[@TimJSwan]

"the concept does not need wind to work" Um, it requires the wind to be a different velocity than the ground, so yes it does..

[@gljames24]

Albatross do it to stay in the air for months.

[@JNJNRobin1337]

oh so it switches from wind power to wheel power?

[@butlazgazempropan-butan11k87]

Cant you just go "diagonally" to go faster than the wind ?

[@hrishikeshaggrawal]

Here's an interesting question, if you design the propeller to have active wing angles, could you make a vehicle with negative coefficient of drag?

[@Leon-eq6ei]

I think this is possible because of you have a plane that is wind powered you can switch your pov to inside of the plane. There the wind is still. But a turbine on the plane would still spin. And the wind would keep it on a constant rotation speed. This can be used to then power a propulsion mechanism. You would propably not call it a negative cw value because of its definition though.

[@nelly5954]

Does the wind need to be blowing with or against the direction of travel?

[@blacklight683]

i thought that it works, but then because your faster than the wind the wind will be pushing you back thus turning it the other way around and slowing it back to wind speed

[@spookykitty2327]

sometimes, things just work even when you think they shouldn't. you aren't smarter than the hundreds of physicists that proved this works

[@kevincaruthers5412]

Are you getting more energy out than you put in? no? Then Thermodynamics doesn't care.

[@pavelgorokhov2976]

A more straightforward way to show that the laws of physics allow this: a lot of wind turbines power an electric train that moves faster than the wind.
