Tritium Wonder what happens when an airplane crash? One might imagine it would be total chaos since the electricity will go out and since there is no light‚ no one can see and people would be trampled. The truth is not like that. Even without electricity‚ people would still be able to see. This is because the plane is equipped with a self-illuminating lamp‚ a lamp that could run without electricity. That way people can still coordinate on the plane and the accident won’t be that fatal. However

Bipolar Research paper Bipolar Disorder P. 1 Of the literal hundreds of mental disorders with which people must contend‚ few are as misrepresented as Bipolar Disorder. Fewer yet have such a social stigma bound to them. The actuality of the disorder seems to be lost somewhere between rushed diagnoses and an uniformed public. This is especially an issue as BPD knows no racial‚ social‚ or ethnic boundaries. Even those in high standing can be affected by BPD. One such case of this was Kurt Cobain’s

Tritium does not occur naturally but it can be extracted from lithium‚ which is plentiful in the earths crust. Creating nuclear fusion is safe too‚ the amount of plasma being used at one time is very small‚ and the conditions require for fusion to occur are difficult to attain. There is no way the plasma can proceed
