For the small ecat eight hours is needed to show that it's self sustaining. Three or more days is needed to show that the source isn't a chemical reaction. The eight hour figure probably comes from the three or more hours that the ecat needs to be hooked up to a power source for it to warm up.
Let’s hear the excuses directly from NASA. They claim superior knowledge in this field ~ so tell us all. We’re taxpayers. We can take it!
That being the case, there should be a finite solution here. Which chemical reactions are capable of being stored in such a small space? And capable of producing that much heat? And able to sustain that production rate for 5 1/2 hrs.
My guts are telling me that there cant be a whole lot of known chemical reactions that would meet the criteria. If there is no known chemical reaction that meets that time line / curve ... then we should give the guy a bit more opportunity to present his evidence. But, once he can prove he is outside the curve, then he has either invented a new means of extracting energy (a plus) or he has created a new chemical reaction (also a plus) or it is a type of process that is outside of the chemical realm (also a plus). But with all of these tests constantly coming up inconclusive and then being required to meet another goal post seems to be a bit disingenuous to both sides.
