If the world would ultimately destroy itself because steven mark is hiding his device and himself, would it be possible to sue him? Or even suing him for something just to find out if he is alive or where he currently lives? Because if he doesn't show up for court, they will have a warrant for his arrest.

Please don't laugh and bash if this seems silly. It was just an idea...

we can sue him for "contempt of the forum"   

I hear you, not a bad idea, but I won't do that to the poor guy.  Just pay the $29 bucks and hire a private online detective, then call him, and wait for his pissed off voicemail.    LOL   

EM

Steven is warning us that if we slightly mis-interpret details, we may well do the destruction by our own hands, on a local scale.
I am not sure anyone can be forced to hand over FE tech, first we'd have to prove he really has it.
Wouldn't want to be in his shoes. It's easy to comment from the sideline.

The only positive thing I could see would be to do it in such a way that he, in some way, also would officially be released from the promise he gave (or had to give) to not talk about the TPU details...

I think your right, Trino. No "Non-Disclosure Agreement" is worth anything in Court. And any employee can be subpoenaed to testify under oath.

Another thing a civil suit could show, is who is really behind "U.E.C." Obviously it is not a real company, with bricks and mortar and products, but is only a holding company that is a subsidiary of another corporation; or owned by individuals hiding behind it... Created only to hold this and maybe other technologies too.

Through subpoenaing the U.E.C. information, the lawyers for the Plaintiffs might be able to show that a corp like "G.E." or "Siemens" was the real owner... Or another major corporation with Public Stock Offerings and Consumer Sales. If the news that a major corporation was deliberately shelving clean and cheap energy technology was ever made public.... What would happen to the consumer sales and stock value of that corporation once the world heard about it? 

Lol once the stock began to take a nose-dive, and the consumer sales started to crash; the executives of that corp could expect to be thrown out of the plane at 10,000 feet... Without a "Golden" or any other kind of parachute

"They" will not have a warrant for his arrest just because he fails to respond to a civil complaint.  I think you confuse civil and criminal law.
