Hide free energy while the economy strains under gas prices? I doubt that.
and it isn't the gov profiting on gas. Exxon makes record profits when they rise. Not the gov.
Understand that I suspect gov is hiding something as well. Just not the scope we would suspect. I think if we did have alien power tech we would be struggling to understand it. Give Columbus the plans and an unlimited budget and ask him to build a nuclear submarine to discover america with. Not going to happen. Does not have the tools to make the tools.
The reason for secrecy is to try for military superiority. Also concern that other countries might get one and solve it first. There is also another consideration. If you cannot gain mastery over your own skies because aliens had superior tech, then you might want to keep that a secret until such time as you could gain technical equality.
Would you expect the gov to say aliens are getting genetic material, and kidnapping citizens for study. We just can't do anything about it. No, they would not admit anything if they could help it until such time as they could dictate to the aliens what will be here on our own planet.
It might be different if citizens were being murdered, but they seem to be returning them unharmed, just a little psychalogical trauma.
Not saying its all true, or that I know. Just making a logical what if consideration.
Whatever works, use it.
A good idea stands on its own value independent of authorship.
If it stands or falls on the credibility of the author, maybe it isn't such a good idea.
