and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Can a voltage exist across an ideal inductor that has a steady DC current flowing through it

yes it can
5 (25%)
no it cannot
11 (55%)
I have no idea
4 (20%)

An ideal voltage source will deliver the voltage selected by the user,for as long as the user decides to change the voltage value.
Yes, an ideal voltage source will change the voltage across itself only when a user adjusts it.
An ideal voltage source will never alter its voltage when the load tries to change it.

In other words:  An ideal voltage source obeys the user - not the load.

If an ideal voltage source can deliver an ideal voltage across any load,what happens when it is placed across an ideal short as the load?-
An infinite current flows and the universe explodes  ;D

An inductor can store energy. 
Yes, unless it is open

A capacitor can store energy. 
Yes, unless it is closed.

an ideal voltage source does not "store energy." 
but it can absorb energy from a higher voltage source or from a current source.
Where does the absorbed energy go?

Here again are the two versions of Brad's coil (ideal in red, non-ideal in violet) current traces on the same plot with the same vertical scaling.

There is obvious expected error with the non-ideal inductor (violet trace), but it is sufficiently accurate to allow us to understand how a perfectly ideal inductor would react to the same input.

It gets sucked into the Dark Energy quantum foam vortex.  Only to reappear later in the Jim Murray Dynaflux Alternator.

"It produces over 250% more electricity than it takes to run it."

Brad, verpies is agreeing that some of the energy stored in the inductor can be absorbed by the voltage source. Or at least I think he is.

What are your thoughts now?
