I was cleaning my house and saw a box full of my old rice engines and decided to demonstrate it to you guys. I saw the original design of this engine from another youtube video several years ago and I could not find the link to put it here. if I find it I ill place it in this part as a reference.
This is a thermoacoustics engine that uses steel wool and rice as a regenerator and heat exchanger. Upgrade in the design and details of how it works will come in separate videos.
Performance is fantastic and is a good classroom project for kids.

Finally I found the original video:
