Uh, the criterion for validity is replication, which has been done, and in the case of Mitsubishi, published. "Public demonstration" has precisely nothing to do with science.

Skeptopath thinking.
Horse sh!t. You remind me of those people who thought that you could fill your gas tank with water and drop a pill into it and drive.
Anything that claims to generate nuclear reactions at chemical activation energy levels needs to be viewed with extreme scepticism.
Not so. The work of Lysenko, the Russian biology fraud, was replicated many times by other self-serving Russian biologists.
