It could be fake, and it could be real, but the idea that international patent offices refuse patents for cold fusion devices is rather strange. That means in order to prove it functions, he has to risk getting his design stolen and patented by someone else should it prove to be true.
Now suppose for a second that this device is real, and also suppose it could possibly be affordable where people could easily supply power to their house, off the grid, and for cheaper than the power companies sell them power?
A cold fusion reactor would be a direct threat to many current industries who have a whole lot of money and power, and they would have motive to do anything they could to keep the lid on something like this.
Cold fusion would immediately make hydroelectric, coal power, nuclear power, natural gas power, fossil fuels, solar power, wind power, all forms of green power, all obsolete. Any industries involved in any of the above would be getting put out of business by cold fusion.
I'm not arguing whether Cold Fusion is real or attainable or not, just that there is plenty of motivation, by plenty of very rich and powerful people and corporations to keep the lid on such a revolutionary technology.
Imagine if you could power your house for a year on a 5 dollar bar of nickel, and a $20 tank of hydrogen, completely off the grid? If you could power a house, you could also have a cold fusion engine driving your car that emits 0 emissions, and very rarely needs refueling.
