That will work great for the thrusters on the green rocket don't you think

A pretty slick machine that faithfully captures the Pentz design concepts and looks to be very efficient! The very small openings in the cap end of each bottle wouldn't handle any chips, however. The base opening in my Clearvue Mini CV06 shop vac cyclone is about 2" and chips descend through it very well. For a sanding attachment, however, this looks like a great design.

I had looked at soda bottles before and wondered if you could make an effective cyclone out of them. I guess so!

Do you loose anything using several smaller cyclones rather than one larger one? Fabrication of smaller cyclones for a full size dust collector probably would be easier and possibly cheaper and allow them to fit places regular sized ones can't. Would it affect static pressure or anything else?

Pretty neat, I hope Bas sees this since one of his former countrymen was the designer, I did not check the website listed in the video since my knowledge of Dutch is about nil despite having Dutch ancestors somewhere back in the family tree.

This thing is no good as a DC- insufficient CFM. It would work fine to connect up to small power hand tools, like a ROS, biscuit jointer, etc.

Yup, I saw it, definitely Dutch (including the caption on the video). Lots of tinkerers there too!

The soda bottle version is too small for a DC, but following the same concept could you make two 14" diameter cyclones instead of an 18" cyclone if you had low ceilings, or seven 10" cyclones? I'm just throwing out some random numbers for an example, but do you lose anything going in parallel vs. a single larger one given the equivalent total "capacity"?
