I noted yesterday that French engineer Jean-Louis Naudin claimed to have replicated Steorn’s overunity motor. Today, Steorn CEO Sean McCarthy provided some feedback to an article about Naudin’s replication on the web site PESN.com.
McCarthy stated: “Thanks for that – however I must urge some caution here, what Jean-Louis will find is that all of his electrical input is being output as heat and that the work done by the rotor is free. However this does not mean that simply putting in a generator will enable him to close the loop.
The reason is that the design of the ‘active’ coils is very important so that the input uses minimum current to cause the effect in question – the production of heat is a current^2 relationship. Unless this fact is considered in the design of the input, then while the system may be more than 100% efficient, the work done by the rotor will be less than the energy input into the system, and so a closed loop system will not be possible.
Our next sequence of experiments will address these issues.
We are quite happy to discuss this in more detail with Jean if he has further interest in replication (two of our engineers are French, so they should be able to communicate well).”
This appears then to be an endorsement of sorts of Naudin’s claim of replication. According to McCarthy here, it is possible to achieve overunity in terms of energy in/energy out and yet not have a self sustaining device in this kind of configuration if the engineering is not done correctly since much energy can be lost in electronics as heat.
