Re: Man Supposedly Flies With Custom-Built Bird Wings
#162I really wish this were real. The only part that really ruins it for me is, where is the battery powering the electric motors? I mean, since I am ignorant about aerodynamics and a bunch of stuff, I can suspend my disbelief about the wing actually providing enough lift, and suppose that there exist incredibly powerful motors that could operate in that way. I would even like to believe that there is an ultrapowerful ba…
Look at your laptop battery, they are around 50Wh which should be able to provide 2kW for almost 2 minutes, disregarding the maximum current it can pump out.
This is what makes me doubt if it really is fake or not. "Why has nobody done this before"? Because light weight power storage and motors has not been available until now. But the videos smell CG so I'm still calling fake on this one.

#163Watch a bird take off. Start with some pigeons, then some sea gulls. If you can, watch an albatross - on YouTube if nothing else. As you get larger, you get heavier; as you get heavier you need more lifting force (ie, bigger wings, moving faster). Recall that weight is a function of volume and increases with the cube of your dimensions, while lifting force is a function of surface area and only increases with the squ…
If we now switch to this mindset, the engineering and tools that we have today should allow us to achieve the desired goal.
So thanks for the hoax, Flying Dutchman - you have started something new here, and your name will not be remembered by what you did, but rather by what you did not and how others used your idea to achieve it.
