Thanks, Doug
Yes, the possibility of dangerous bad behavior is real - for an example
http://en.wikipedia.org/wiki/TATPThanks for the run-down - I have no formal education in chemical engineering, but have read on the subject over many years, leaving me with a spotty understanding and no lab skills. I'll think on the hydrazine reaction until I understand it.
It is probably obvious, but the business with bad behavior, the risks, seem to vary with, well, bad behavior by so-called "leaders". eg if a country invades another and blows up people and their houses and kills kids and old people, well, it pisses people off, and a few of these people sometime then do mean things. Best to be nice, share, and get along...
wiki says this about hydrazine: " Hydrazine is highly toxic and dangerously unstable, especially in the anhydrous form. Symptoms of acute (short-term) exposure to high levels of hydrazine may include irritation of the eyes, nose, and throat, dizziness, headache, nausea, pulmonary edema, seizures, and coma in humans. Acute exposure can also damage the liver, kidneys, and central nervous system in humans. The liquid is corrosive and may produce dermatitis from skin contact in humans and animals. Effects to the lungs, liver, spleen, and thyroid have been reported in animals chronically (long-term) exposed to hydrazine via inhalation. Increased incidences of lung, nasal cavity, and liver tumors have been observed in rodents exposed to hydrazine."
At some point I expect I may do some very small scale 'speriments with dirty lube oil, test tube size stuff. Getting the glycols and the suspended carbon to move over into a watery phase can't be that hard to do safely. Then a few cycles through a nice filter and dillution to fuel suitable for a listeroid.
