Semi-Artificial body system

[johnwM]

Hi,

I am doing a science project to make a semi-artificial body. I found a lot of issues in my project and fixed them. But I'm not sure if there are more issues I couldn't find (and I also don't know if it's possible!). Can anyone help me identify issues in my project, or else a person will die.
