A computer being built by a company in Chippewa Falls is said to be the most powerful computer in the world. The super-computer company Cray Incorporated is constructing the computer for a Tennessee company. Cray’s C-E-O says it will be faster than the top 160 super-computers combined. The machine will weigh more than one million pounds and carry a price tag of 600-million dollars. The work should be finished by 2021.
