I'm building an organic engine that runs on meat. The cats are still in one part but I will soon find a way to remove their extra weight. On the front of the test vehicle I've put a meat-grinder, this allows me to collect fuel any place and in full motion!
Of course there still is the efficiency problem of having to feed the engine while the car is standing still. So, I've quite cleverly (if I may say so myself) developed a system of inviting sceptics to come and have a look at the thing and see that it really works.
