Thats a good point.. A single cell has no brain nor consciousness but has life. So if we actually put all the components together into a dish and try to get it to run like a circuit, it should by all means power up.

I must say I feel glad that most of the tools they use are the same as we use on earth daily, even up to the red rubber grips :)

Kevlar is all good when dry.......

The trick here is the infinite additions.

Yes a very cleverly executed one.. unfortunately the cameraman did not go around his bag for a detailed analysis.

I am not too sure if what he discussed is accurate.. after all a year can be divided into 12 months and plenty of predators do not live just by years alone but by number of months. In this case 17 years as a prime number to avoid predators does not hold water so much anymore..

I am wondering how many hours was spent designing the circuit and then laying out the PCB? Circuit design software must have been close to non existant then.
