In this video Mr. Newman has mechanically connected Big Eureka to his Newman Generator. The electrical output of the generator is charging a bank of nine 12 volt batteries. Those batteries, in turn are powering Big Eureka. There is NO additional energy input into this closed system.

Big Eureka was run in this configuration for two sequential one hour tests. The voltage of each battery in the bank was measured before each test
and again at the end.

The remarkable fact is that at the end of each test run, the batteries all had a higher voltage than they did at the beginning of the run. The system was doing work and at the same time, the energy stored within the battery bank, was increased, not depleted!

As a control example, one battery was used to run a small motor for less than one hour. After one hour, that battery was significantly depleted.
