From someone who has multiple patents ... in mechanical patents, there is a BIG DIFFERENCE between paper and working prototype. Invest in the time / effort / money to build a working model. Once you can show that it will work, you will have much more capital available to you. Until then, it’s just another (good) idea.
It doesn't really even need to work. Just call it "green," say that it will reduce carbon emmissions and hack into Amazon's database for the names of people who bought algore's books and movie.
These are the suckers who'll be willing to throw good money your way whether it actually works or not.
