Heh, Joker made a thead just like this one...
I'd patent it and then black mail the car industry/gas industry and compare which would make me more money going into buesiness myself or getting an exorbiant amount of money from those companies. With that money I'd buy a small island with a tribal people, and then put them all into concentration camps in which I'd rape them of htere humanity, and kill anyone over the age of 25 thus making sure I'd have only mindless drones, women would be use purely as a way of controling my soldiers primal needs and another tool for dehumanization. I then conquer the closest most rich neighboring island and repeat the process till I control the entire island chain and of course the UN and US wouldn't give a **** because it in no way affect them, then I'd of course slowly take over a small asian country. And soon I'd control a land mass close to the US in size and money, and I'd make one last conquering move, conquer a country which in some way directly effects the US in terms of exports and imports, then I'd stop and I'd be a world power... Biding my time to control the entire world!
