Another price for the project was for 130 billion in 1996 prices, as factored into project cost per percentage of the GNP of 1945.
The Hanford and Oak Ridge sites had the benefit of abundant hydro-electric power needed for the project, none of which was easily available in Nazi Germany. These sites were also massive industrial facilities, that could not be hidden or their use disguised from aerial recon. If Germany had constructed similar facilities, they would have been bombed to oblivion once they were seen being built.
The number of scientists and technicians needed for this project was available to the allies, since they pooled their personnel to work on the many details of building the bomb. Germany did not have the resources to do this, without impacting many other programs and its war program.
