And you ignore that 3d printing is not about printing things you can buy.

Where can I buy a Garmin to BMW GPS adapter plate? nowhere
Where can I buy headphone hangers for my specific desk? nowhere
Where can I buy a Death Star dice box for my friends that are Star Wars RPG lunatics? nowhere
Where can I buy a switch delete plug for a 1979 civic? nowhere
Where can I buy a China bolt style red 3Watt LED to Yamaha rear tail motorcycle mounts that look stock? nowhere.

3d printing is for creating and printing things that you can not get, its for people that use their brains and create and then want to effortlessly get a plastic part.

It has never been a "print out these things that you can just go buy" and I have no clue at all where you got such a horribly uninformed idea that it was.

Musk is the only man that is actually building shit to help society and further humanity while making a profit.

The other two are simply hiring others to make money off the masses for personal gain. Bozos and Zuck have done absolutely nothing for society, in fact many would say that have done the reverse.

Yes and Yes. and if we find a way to make a LOT of electricity, 10,000,000Kw of power into one will produce 1000N of thrust assuming a linear scale up.

      What is needed is to see if the drive will actually scale up.

The other thing is, now that it is proven to actually work, refinements can be made to the whole design to increase efficiency that may give us even more thrust per KW of electrical energy.
