Last night, I got an idea while sleeping. How about using Acoustic Levitation to fake gravity in Space Stations.
Acoustic levitation is also known as ultrasonic levitation, acoustic tractors, and ultrasonic tractors.
The reason I said “fake” is that we are not really creating a gravity field but instead we are using the principle of acoustic levitation to push the astronaut towards one direction (which would be considered the floor).
Note: I don’t know if this is a good idea since I don’t have the budget, the knowledge, the time or the way to experiment this concept; however, if this is actually plausible, then I think it would be interesting to experiment and find out.
I am not going to over over the details of Acoustic Levitation in this post since there are many places where its explained such as HowStuffWorks (check link here).
I leave you with some videos below showing how acoustic levitation works.
This is a video made by Argonne National Laboratory:
And here is a video of BristoLIG showing how to make one at home:
