We had ran with the idea of using energy as our power source for the world. In the design we decided to go for there is a giant Vespa like headlight in the middle of the world. We realised that the world around it could power this headlight, projecting the light outward.
The Vespa headlight. (I.ebayimg.com, 2016).
So what could power such a headlight? We mentioned previously that the human population could be dead energy- their bodies using the electrical impulses that power them. I wanted to calculate the power of the human population of Rome, so had to do a little bit of maths to figure this out.
Calculating the energy output.
So the population in Rome is 2,864,348. The average person makes 8 million Joules of energy per day, so in Rome 2.29148e13 joules of energy is produced by the human population per day.
In an average city of size 1.258 million, around 50e9 Joules of energy are used in a day. So therefore in Rome, 113.85e9 Joules of energy is used.
So in conclusion,
1.1385e11 Joules are needed per day and the city makes 2.29148e13 per day. So, the city itself makes enough to live on. (Quora.com, 2016).
