What would be the potential thrust of an "electric jet" like Lilium's? Lilium claims to fly with "electric jets". Throwing out the debate over whether a non-combustion compression of a stream of air is a jet or only a ducted fan, what is the potential thrust each of these could be getting?

Edit: since it's not compressing, what potential lift could the Lilium prototype engines provide, and are there examples of electric engines today that provide compression in a significant way?

Ignoring the stability issue of Lilium as well. Just curious about the ducted fan design they have. Also ignore the problems with it being electric and battery powered please :)
They look like 15 cm fans, thrust of which is competently ROM-ed in this answer.: about 40 to 60 Newton.

Note that the $C_T$ in the equation depends on fan solidity, the higher the number of blades and  the wider they are, the more thrust they produce, but also the higher power required. For a given fan power (and battery life) it makes more sense to increase fan diameter and decrease fan solidity.
