 | | The vacuum tube-based computers built for the SAGE project, which was the brain child of physicist George E. Valley, were even larger than the ENIAC (in fact they are the largest computers in history). |
 | | The total project cost of SAGE was around $10 billion (or $60 billion adjusted for inflation), which is more than double the inflation adjusted price of the Manhattan project that built the first atomic bomb! |
 | | Their power consumption was enormous; if you ran a SAGE computer in your house today, your electricity bill would be around $150,000 per month. |
