This has no production value. This is great "look at this thing that we can do" video but the reason no one else attempts it is because there is no next step. They didn't just stop at 744 meters for no reason, fuel is the limitation here.
It is impossible(unless you want to build something the size of Saturn V again) to put enough fuel on a launch vehicle to carry a satellite to orbit and then land it back like this.
I don't have the exact data, but as an guesstimate it would take twice as much fuel(fuel + "return fuel") to land the rocket back like this. We also need to put in extra fuel to take the "return fuel" up there in the first place...you get the idea.
Extremely un-economical. I do not see a next step for grasshopper because building another rocket is cheaper than returning the engine back like this.
