Abstract: We introduce a new method to detect the absolute neutrino mass scale. It usesa macroscopic mass of tritium source. We explain that the neutrino mass can bemeasured by scaling the mass difference of the source between initial and finalstate, and its heat value. This method is free from the electron energyresolution limit and the statistical error. We estimate the required accuracyto measure the neutrino mass. We also report that the {u,d} component of theCKM matrix, |Vud| may be determined in 10^-6 accuracy as an application ofthis work.
