I mean, it's a product that has been available since the early 1970s, so yeah, there is a small market for it.

@@0106johnny 🔴 What Is Islam? 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

That would be amazing to get little blasts of wind on your face after an explosion in a VR game. Or even opening a door or window of a moving vehicle.

@@thebaddestogre-3698 Yea, I was thinking that it would be best to have a minimum of 3→4 of these solid state fans. Aimed partially at your neck, you'd be able to give more accurate directional wind effect. If you used binaural audio to create a truly 3D wind effect, the player would be able to tell exactly which direction that the wind is coming from. I'm also assuming that these solid state fans can get a lot smaller than traditional fans.

Hi there! That is an excellent idea and could be done smaller and lighter than magnetic fans.

@@thebaddestogre-3698 This fan has 0 static pressure. meaning it moves air but you wont really feel the air. Its boggling to see it move smoke as well as a normal small slow fan but feel only the tinniest amount of force from the blowing air. so unfortunately it would not work in VR plus it would take way more room than a small fan.

The thing has only one resonant frequency, so why do you want to put other frequencies through it? Other than curiosity of course ;) If ou feed it a nonresonant frequency then you simply make it inefficient.

@@rhalfik I'm not asking about being able to input different electrical frequencies. I was worried that this would make a hum at a narrow frequency range and if changing the geometry could help flatten the frequency response.

Hi there! It is not superior, possibly lighter and lower power consumption.

Hi Travis! This could be done. Although, it would be easier and cheaper with an off the shelf magnetic motor.

Hi there! In principal, yes, but we haven't seen this idea completely prototyped.

A piezoelectric crystal generates no magnetic field.

Hi Seppe! At the present, induction would be cheaper. However, it is also heavier, larger and higher powered.

Yes but the frequency of operation will be close to 0 Hz

I see so it does create other issues

Hi Colleen! The fan is not really a good pump, i.e. the ability to transport air from one location to another through a tube is very limitied.

@@MideTech oh it's moving through a tube. I thought it was pushing free air.

lifetime ? for this product

Hi there! Yes, you can!

Hi there! Correctly designed, a thermoelectric source with the right environment and drive circuit could do it.

@@MideTech sounds great, but even more. What if we put heat pipes, the one out of copper and water vapor inside, on the ceiling, from one side to another multiple rows, while being cooled by this small fan. Would that be enough to cool the whole room even on hot days?
