I've had an idea for quite a while for a mod to connecting rods and pistons that could substantially change the character of ICE's, but it's been my experience that with this type of idea, unless you have the funds to complete prototype research, construction, and testing- you are dead in the water. No one wants to risk anything until it's a sure thing. The US was built on invention. In today's environment, Invention is stifled and choked to the point that only business has any chance..... that's sad....
EDIT: Even when you do have a good idea, a prototype built, and testing complete (IOW, you are ready for manufacture), it is still extremely difficult to get investors. That is the problem with
this engine. Ver, very sad.
