It potentially could. It may not be very effecint though. U may need "fins" like that of a compressor wheel in a turbocharger.
U need more surface area while the disks are smooth. So a few more this disks could help. This is a tesla turbine. If u add fins it would be called "tesla's fan pump" whcih ,1, isnt right, 2nd, it doesnt work the same way, 3rd -its a whole lot louder then the actually turbine speed. The fins can also cause a very large resistance. It will spin slower thin it is capable. This can also lead to lots of rattling if the fan is unbalanced. Also the fan may act as a compressor wheel like one in a turbocharger. This will create more resistance to work against. How ever if u ruffed up the disks with sandpaper, it will have more torque, but again, it will mess with the air flow a little bit. So u may need to do some slightly bigger exhaust ports for better flow. As asked, a gear box or g…

How ever if u ruffed up the disks with sandpaper, it will have more torque, but again, it will mess with the air flow a little bit. So u may need to do some slightly bigger exhaust ports for better flow. As asked, a gear box or gear ratio added to it can greatly increase. For more torque, the ratio of the turbine shaft to the slave shaft will need to be greater thin 1:1.1 gear ratio. So if the drive shaft (turbine) is connected to a pulley or gear that is 1.1 times bigger (.1 change difference in size) then the torque wull change. In this example of 1:1.1, u will not see a noticable difference. I would do a ratio greater then 1:2. This can drematicly increase the torque. It will be a very slow speed but it will be strong with turbine at high speed. That number can increase if there are more gears. Like 1:2 gear to a another 1:2 and so on... it gets stronger and stronger. (At least till the final slave pulley brakes because of the torque load lol). If u do the gears the other way then the speed increases while torque decreases. ( just if u want your turbine that spins 70 thousand rpms to increase to 120 thousand rpms)-(insane) ur ideas would work. The "fin" one just wouldnt be a tesla turbine. (Remeber sand paper) sorry if the explenation is sooooo long, so ill just make it loooooooonger lol
If u use a tap and dy set then just thread the shaft and use very small, light ,thin nuts like wat is used with potentiometer on soundboards.
U just need a good round housing. He used clear acrylic to see through (which is kind of cool). But something round could work just as well if done right. Also the square acrylic piece he used made it easier for making it stand upright withou falling over and he could use it mounting hardware for the other pieces. But as i said someyhing (like pvc) could just a little harder to work with.
