Just a short alternative look at the origins of the Matrix.

The computers had won, but due to the actions of humanity in cutting out the sun, a new power source was required. Bioelectricity was the choice but what was to supply it, the original thought was to use the heat generated by human bodies, but this was demonstrated to be inefficient and wasteful.

Why?

Cows, lots of excess heat generated by their digestive processes, with the added benefit that an extensive virtual world is not required, green field, grass and the occasional bull being all that is required.

The End...Or is Miss Daisy the 'One'
