It was on February 27th, 1892 that Diesel filed a patent inside the patent office in Germany for his method and design to the combustion engine. He sourced contracts from firms that manufactured machines and began his experimentation stage. During this stage he constructed working types of his design so as to construct the most efficient engine of these time. However the humans living for the spaceship were different to the humans who're living on the planet now. They were so fat that they are struggling to walk. they travelled around in motorised chairs with a monitor and cup & straw attached, chatting on phones and when they happened to fall out they just laid there until a robot came along and picked them up. The adults were fat, the children were fat! They just laid around all day consuming doing no exercise what so ever and to quote the captain, "Computer, define dancing".
