Actually this is not a very bad idea, but for now, unfeasable. Yes there's weight ration's and magentic fields to consider, bu hear me out.
Say sometime in the future NASA develops an extremely light solar cell that has a self-contained magnetic field. It's all very scientific so I won't go on to discuss how it'd be done. That would be step one.
Now, completely replace the fuel tanks in the aircraft with two high-powered electricity cells. Apply the solar cells to the wing an tail surfaces, but not to the aircraft body itself. This will reduce or eliminate any effects the cells would have to cockpit instruments. Furthermore, use a percentage of the jet exhast to heat a storage area of water to become steam, and tunr another generator, which would supply power to the two main cells in the body. Plus use of the GEN function on the engines would help as well.
Now, challenge GE to develop an all-electric engine requiring no fuel and a high amount of power.
Put this all together and you have a hybrid plane. It's all-electric, powered by two enourmous cells (batteries), and is recharged by solar energy, jet exhaust, and engine turbine power.
What you have is a plane that recharges itself, runs partially off solar energy, and entirely off electrical energy. This works well below the cloud level and at night too because you have a battery as a main power source, and in that situation you still have the exhaust and GEN to recharge the cell.
It's a wonderful idea!!!!
I commend you!!!
And think, this might be the way we fly in a few decades, who knows?
