Here's next week's video, early for Patrons. This one goes put publicly on Tuesday 31st. 

I'm thinking about how I can make seals for the next version, the cylinders will be much bigger and also slower moving, so it might not be as hard as I thought.

Air Engine 2 - PREVIEW VERSION

You can’t suck yourself along with a vacuum cleaner, so don’t bother trying that. However, I did build a vacuum cleaner powered air engine which I could ride along on. This design was inspired by YouTuber Matthias Wandell, and his original design was made from wood. I’ve built a few projects recently where I pushed myself along with electric ducted fans. These run on a 6S LiPo battery and draw 80 Amps each, so they are rated at nearly 2KW each. That gives us quite a lot of airflow, and also quite a lot of pressure. Project Air recently built a hovercraft that would carry a person with just four of these EDFs providing air to inflate the skirt. So this time I’m going to build a two cylinder version of the air engine, with each cylinder being driven by an EDF. We’ll see if this is more efficient that just blowing the air against the atmosphere to propel me.

I love your work. I'm looking forward to seeing the difference with double or quadruple the area of the piston.

Loved it! I am amused by the idea. A battery powering an electric motor with a fan to blow air into an air motor to drive a wheel that could have driven directly by an electric motor to begin with. Seriously, not being sarcastic. I love and have fun with the convoluted nature of the exorcise. And yes! The second I saw the size of the pistons I thought they probably were going to be too small. While it will move slower as you note, you will gain so much more in power with a larger bore.

Pretty sure the next one will have a shop van on board powered by a main inverter and some batteries.

There was once a no-leak air actuator that used a deep diaphragm, which rolled on the piston and in the loose-fitting cylinder. We used to use them on each end of remote actuators, a long tube connecting two of these. Press one end, the other pushes out, and force goes both ways. Simple, and no electrical noise.

Sounds interesting. I think my next cylinder will just be massive and move much slower so it shouldn't be so hard to make some sort of seal. I guess this method would work if I had the right material.

I think they were called BelloFram rolling diaphragms but they don't seem to exist in that exact form anymore. I do see some interesting long-stroke rolling diaphragms from other suppliers, though.
