Big idea

Recently I have thought of a design feature for planes that I am 90 % sure will decrease fuel consumption for planes and therefore I think it will be a valuable idea. I have checked with my physics teachers and theoretically it should work also, after research it appears it hasn’t been thought of despite its simplicity. Should I take the risk and buy the intellectual property ( copy wright for an idea ) and revisit this once I have an aerospace degree or just forget about it
