He didn’t have access to modern day computers. A lot of research is in progress and you may wonder how they work. Good news! You can build one in your home with some hardware store parts. Here is an instructable on How to build a Vortex tube in your own home!

My undergraduate research project is on the computational modeling of the vortex tube. The long term goal of determining the most important geometric parameters. It is also important to determine how each of these factors into various fluids, specifically hydrogen. With patented technology the plan is to use the vortex tube in … » More …
