Over the years, due to a chosen alternating focus, projects differed over three mainstreams:
Here you can find information about projects that are in some way related to water. This may be about measuring flowspeed, about quantities, temperature, flow, density, form, art, waterplanes, turbines, propulsion etc.
Air is a different story in all; one can do all kinds of research and have fun with it; get lost in this fun, only to pick up the serious research of air again later, for sure.
Everybody looks at the possibilities of cars, bikes, speed, building, etc
So does Xietzo, only differently.
