Here is the thing. Have been doing theoretical research in engine designs and have one that seems quite good. The basic idea and concepts have been patented. It can have many applications and modified for many different uses. A small scale model outlining the basic concept works quite well and is ready for further testing as a full scale model. I want to know how to obtain financing to continue with research and development that would cover full scale model costs, testing equipment and salary and overhead costs to build a team to carry out the testing and business issues. I have heard of angel investors but don't know a whole lot. Its preferable to obtain the seed money without signing basically all your rights for the idea and earning potential away. If anyone can help it would be appreciated.
