I have an idea for an invention. Not so much one particular item but for a process created by existing items that could be applied to almost every facet of our everyday lives. It could not only save people money but also our natural resources as it is a very "green"idea. It could kill our dependency on oil. I could build a prototype but don't want to share my idea unless I know it is protected. I don't know where to start and am not sure how a patent or other would apply. I have been "kicking" this idea around for a long time but think that now is the time to do something. I even think,well a friend said to me, that big companies might even pay to keep it quiet. In the right hands it could be a billion dollar idea but i am not interested in that as much as i would love to just see it come to light.
