If you model your fuel after the gingerbread man

This whole idea came to you in a dream: A strange bald men in a ceremonial robe handed you a gingerbread man, and the cookie came to life, radiating this powerful energy. It smelt so good, and so you grabbed it to take a bite. Yummy!

You begin with your own DNA hand squeezed from your own orgasms, but this takes more money than you have, as you have so soon spent everything buying equipment and cookie dough.
