Good thing then, that this is run by government, and that no sensitive information is shared with any private company.

The point of the "app" is that a website can send a signed verification request "is this person over 18", and the app will, if the user approves the request, give a signed response of "yes" or "no".
The website never sees the actual age of the user, nor any identifying information.

You may know about it, but you are doing a terrible job of explaining it :)

The keel of a boat has nothing to do with it. The keel has no effect when going straight in the direction of the wind. No "ordinary" boat can go faster than the wind, going straight in the direction of the wind. (One could, in theory, make a Blackbird-like boat that can do it, though I think the friction/drag of the water would be too much of a problem to make it work)

The wheels of Blackbird power the fan, not the other way around.
The fan of Blackbird actively pushes against the wind, just like the propeller of an aircraft. This slows down that wind, which is where the energy comes from. But this is nothing like a windmill, where the wind makes the blades move. Blackbirds wheels make the blades move, while the air tries to slow down the blades.
In your pickup truck example you do not make clear what makes what move, and a pickup truck has an engine, so the example makes no sense any way.
