Plastic magnet field controlled by light

[Honk]

I'll bet almost anything that a regular solar cell is many times more efficient than this "mag-light"

Well with this material we can build a rotating generator that get it's energy from the sun.  But only if the magnetism cuts instantly as the light goes out.

You only need a little piece of this material to build a small motor. 

This is interesting, could be the key for free energy!

Look Honk, you talk about efficiency and other parameter we all know are needed to achieve high performance motors, but think only in a "magnetic stick" as a rotor, and you have only 2 magnets on the sides 1 N facing the stick and 1 S facing the stik.  You only need to change the polarity of the stick to make it move.  If the magnetic field changes only by light...

I am sure you could use this to make some king of rotary device, but I was thinking more on the lines of a pump. You put a weight on the bottom of a piston that weighs the same as the lifting power of the 60% reduction in force to pull down the piston and then when the green light force of 150% is applied, it would pull up the piston.

Honk, dude, investigations on magneto optical components are based on the teory of being more efficent and faster than traditional electromagnetism 

[Honk]

I doubt more efficient, but most probably faster and easier to miniaturise to fit inside a chip or harddrive.

This is a amazing break through. This could be used for what all of us magnet motor over unity searchers have been looking for.

If the blue light creates a draw and then the green light reverses the effect by 60%, it would only require a 40% placement difference with in to two distances from the magnets to get rid of the draw back effect.

I see this as a amazing opportunity for us provided we could get our hands on the technology.
