This generator produces electromagnetic waves in a helical pattern that knocks electrons loose off of atoms‚ in order to turn the gas into a cold plasma. The cold plasma can reach temperatures at or above 5800 degrees Kelvin (“Our Engine”). The cold plasma is a mixture of the electrons and the ionized atoms. The shell and components are protected from the intense heat through the use of magnetism. Next stage of VASMIR is utilizing another coupler called the Ion Cyclotron

CHEM 3411‚ Fall 2010 Solution Set 5 In this solution set‚ an underline is used to show the last significant digit of numbers. For instance in x = 2.51693 the 2‚5‚1‚ and 6 are all significant. Digits to the right of the underlined digit‚ the 9 & 3 in the example‚ are not significant and would be rounded off at the end of calculations. Carrying these extra digits for intermediate values in calculations reduces rounding errors and ensures we get the same answer regardless of the order of arithmetic
