There are also more useful applications:
would this workbench, and/or any of the related tools (OpenGlider ?), work also for hang-gliders ? In other words, can this calculate aerodynamical forces and the resulting deformation on partially sustained tissue ? The main difference between a paraglider and a hang-glider is that for the latter the leading-edge is rigid, formed by some stiff "rod" (or similar).
try the Assembly4 workbench for FreCAD v0.19
install with Tools > Addon Manager > Assembly4 — tutorials here and here

No, openglider and the corresponding workbench for freecad supports only ram-air designs like paragliders, parachutes, and kites. Also, it doesn't allow to compute fluid-structure interactions. (At least this is not possible yet).

Thanx. I already seen this approach. I'm not sure if this is the solution, but it's a fact that the momentarily used Windgenerators are not as efficient as could be. Also the possibility of storeing the windenergy in Hydrogen is not explored enough in my opinion. Even if the coefficient of H2 is not that high, because of the transferency loss, wind still is a free and massive source of energy. Scientists have proposed to store the hydrogen in the already exisring gas-pipe system, for quite a while now. But nothing happens and the puplic is left in the dark. It's no problem at all, and we would have enough capacity for everything. An alternative to H2 is Windgas, which is H2 comibined with another gas. Stil being environmentaly safe. Also the electrification of cars and such, will only be a short interrim, creating money for the industry, mainley because of the batteries that are needed and the resources to build them. Electric cars are not environmentaly friendly at all. The longterm will and must be hydrogen. Combined with a society that is able to use public transportablity much more versatile, in the near future, self-driving cars f.e., can reduce the carbon footprint of mankind to an absolute minimum. But you know... Money makes the world go down(round?).
Of course this is another topic and exceeds this thread.
