Free energy = suicide. stay away youre not ready

Bullshit.

No complete disclosure for easy DIY replication in garage/shed of your "greatest invention" = suicide.

Obviously so named "closing inventions" is a greatest threat to corporations and elites. And the threat is not an invention itself, but possibility that everyone will be able to replicate it. As soon as inventor keep some secrets that not allow third-party replication, inventor is a primary threat source, because he could leak this important information to the public. If information is already leaked, inventor is not a threat anymore and elites have much greater problems already.

This pattern of "Inventor made a great invention, inventor kept it in secret in the hope to sell it or find investors and became new billionaire, Inventor died in accident" is either complete stupidity of inventor, either just another scam.
