If the battery is being used for control electronics then it is reasonable. It should not be difficult to confirm that is its purpose.
There is no harm is reserving judgement and leaving open the possibility that the gadget is real. If it is not real, a million people will pile on to the inventors, so we don't need to. I would like to caution readers that this argument by Stephen A. Lawrence is logically invalid: Looking like a scammer is not good when you're trying to lure investors. > > Really talented con men show you everything, and convince you it means > something other than what it really means. That cannot be falsified. By that standard it is impossible to distinguish an honest inventor who is showing everything from a con-man who is only pretending to show everything. Every step the inventor takes to bolster his bona fides also bolsters the likelihood he is a con-man. This reminds me a little of the Soviet Union kangaroo court judges who claimed that protesting your innocence merely proves you are guilty. Anyway, we have to put aside judgements of the people involved and look at the technical issues only. Bear in mind that odd people sometimes make valid claims. It happens a lot in cold fusion. - Jed
