Carbon Based Lifeforms - Supersede

with a world tour of the aurora borealis.

The tracking is automatic with the heliotrack.com 2 axis tracker, it is super precise and works very well, it has automatic return at night. For the technical data of heat, flow etc ..., I am awaiting my order of graphene powder (2-3 grams). I will do tests with cal fluid ...

Like what there was progress ..... for cesium 137 which has a period of ultra rapid degradation.

Professor do you have the curves of all isotopes and their degradation?
