NASA came up with a similar concept to yours.
A satellite that absorbs electricity from earths magnetosphere as it orbits the planet. It never happened however, as the energy output wouldn't cover the costs of producing the satellite, sending it into space, and then running it/maintaining it.
The bright individual who came up with the idea was written off because NASA claiming that even if a single unit ran for 500 years the cost wouldn't be covered.
Good thinking however, keep up the sharp imagination.

Great idea.. I actually have "invented/discovered" something along these lines. Basically, I take a large rare earth magnets put it under a table (2 in x 2 in disc with a 370 lb pulling force). Then put a sphere 1.5 in sphere rare earth magnet on top of the table. The magnetic attraction keeps them both in place. Then I take a 1/2 in sphere rare earth magnet and place it in the "orbit" of the 1.5 in sphere. The interaction of the the 1.5 and 2 x 2 magnets create a pocket where the 1/2 in mag just sits in. Then I put my finger on top of the 1.5 in sphere and "process" it one time (just like the Sun but with out rotation). The 1/2 in sphere magnet in the orbit starts orbiting the 1.5 in mag at high speeds and keeps going for about 30 seconds until I "process" the 1.5 in mag again. You can repeat this over and over again forever. Magnets in motion with copper wire positioned perpendicular generates an electrical current. So I took winding of copper I had laying around and put it above the spinning magnet. I hooked that up to an LED light and it lit up.
I still have a lot of experiments to do but I think the electricity created is more than what it would take to "process" that 1.5 in mag every 20 seconds to keep it going forever.
Then.. if you think about it.. you could easily upgrade this to any size you would like to power, say a car, an entire house, maybe even a whole town if it were big enough... (I think smaller applications would be more practical though)
This does not defy the laws of physics.. energy cannot be created or destroyed, because the rare earth magnets are actually zapped with large amounts of electricity when they are manufactured.
Anywho.. I've got to get back to work...

As has been stated, the initial idea wouldn't work, but as has also been stated, keep thinking! I have had a lot of 'bad' ideas that proved to still be useful for something that at first seemed completely unrelated.
Keep in mind that science is not divided into different sections; that is only how we as a society perceive it. Energy is out there, and while it's never 'free', can never be truly 'perpetual' (things break, that's life), and never can break the (true) laws of physics, it can be cheap and plentiful.
Remember Edison: "Invention is 1% inspiration and 99% perspiration."

hi - the obvious response is why not just tapp the output from the solar panels DIRECTLY ? i assume you
the way i read it - you intend to supply electrical energy from solar panerls to drive a motor to spinn the gyro
then tap the gyro to produce power
if that assumption is incoreect then my appologies
but now its laid out - can you see where the losses occur ?
efficiency of the drive motor to spin the gyro is < 100%
the gyro itself presumably has bearings - which have a friction load
as stated previously - the gyro will loose enegy from micro gavitational pull and interaction with particles - a very small loss - but its occuring
lastly - what ever means you use to draw enegy from the gyro and convert it to a useble force has both an effeicency rating AND exerts a braking force on the gyro
the only convebale use of a system such as you describe would be to maintain power while the solar panels are in darkness - but IMHO battery banks would be more efficient and have a higher energy density than the gyro and its associated equipment
