“Japanese Student Takes Flight of Fancy, Creates Flying Bicycle” [https://www.youtube.com/watch?v=ZJrJE0r4NkU](https://www.youtube.com/watch?v=ZJrJE0r4NkU)
*Edit: Far beyond regulations and air traffic control issues, only regarding to physics:*
I’ve just seen this video of a Japanese student that has achieved making a flight of about 200 or 300m with a mechanism that turns the pedalling we normally do in a bicycle to the turning of a propeller.
Now, if we as humans and a very great bike can reach 40-50 mph (and very light planes such as cessna can take of with only 60mph – not to mention Bush Planes – all of these weighting easely 4 to 5 times the weight of a person + an extra light airplane design, specifically created for that porpouse) – why does this seems too hard to achieve/sustain? I can only guess its a matter of efficiency (or the lack of it), but which one of them?
In: Physics
I mean you see how much wingspan this thing needs to get airborne, it’s extremely inconvenient and not at all useful (doesn’t go particularly fast, can’t really turn, probably breaks easily if you have any obstacles at all, doesn’t work in bad weather, etc.)
