I happen to be VERY in-depth into this subject, and i can tell you something about it... Do your research.. because you'll find there are soooo many more ideas out there than what you can just see... And FYI, the moller skycar can fly forward, it just is not alowed to because they are not legally alowed to fly it over land, and claim to need to make a lake... That is, if they are not lying about the amount of horsepower it has.. I belive with the system they have (which i actually do not think is very efficent) Is doable...
And for other aspects.. Theres a man named Henry Coanda, and he has made a solution for this.. Its called vortex thrusters, and as unreal as it may seem, it is more real than you can think... In fact, its takes just as much time, effort, and HP to make something that is 10 times more efficient for its size..

And dont forget about these little things called "lifters".. These work for sure, because i mad one... No moving parts, with complete off-the-ground hovering... too good to be true? I beg to differ;
