Tomgine open source motor as opened in the right image. In this image you can see the permanent magnets which work also as the bearings of the motor. The solenoids are missing from this image yet. This crude prototype has produced some electricity in the test and also at the Finland's Foundation of Innovations.

This image right  of the airship shows the air ducts which suck the polluted air inside to the airships cleaning factory. In this example there are 9 units. The diameter of this flying disk could be one kilometer or even more.

There is lot to clean and we need man airships like this. The task to make all these is enormous but I believe that the together we will make it.
